A waterproof camera device and its focusing and zoom adjustment mechanism

Abstract

This invention discloses a waterproof camera device and its focusing and zoom adjustment mechanism. The adjustment mechanism includes a mounting base, a first fixed gear, a second fixed gear, a movable component, a transmission gear, an adjustment component, a first transmission assembly, and a switching assembly. Through the control of the switching assembly, the transmission gear can switch between a first position and a second position, thereby realizing the focusing and zoom adjustment of the camera inside the waterproof housing. This meets various needs for composition changes and sharpness adjustments during underwater shooting, adapting to more shooting scenarios. More importantly, the focusing and zoom adjustments share the same set of adjustment components, eliminating the need for two separate mechanisms. This significantly reduces the space occupied by the adjustment mechanism inside the waterproof housing, without increasing the size and weight of the waterproof camera device, thus ensuring convenient underwater operation and a good grip.

Description

Technical Field

[0001] This invention relates to the field of underwater photography equipment technology, specifically to a waterproof camera device and its focusing and zoom adjustment mechanism. Background Technology

[0002] Underwater photography is an important branch of film and television special effects photography. Its core lies in the photographer carrying a camera or video camera equipped with a special waterproof shell and using diving equipment (such as a breathing apparatus and buoyancy regulator) to dive underwater and record images in high-pressure, low-visibility, and complex current environments. This technology not only realistically recreates the magnificent underwater landscape, such as coral reef ecosystems, fish migrations, and seabed topography, but also provides valuable first-hand data for scientific research fields such as marine biology, geology, and archaeology—for example, mapping shipwreck sites and studying the changes in ancient coastlines. Furthermore, underwater photography plays an irreplaceable role in underwater engineering acceptance, sports training movement analysis, and science education. With advancements in waterproof materials, sealing techniques, and digital imaging technology, underwater photography has gradually moved from early professional exploration activities to civilian use, becoming a popular method for diving tourism, underwater wedding photography, and short video creation.

[0003] In terms of camera operation, the zoom and focus rings on the lens are the core mechanical components for adjusting composition and sharpness. To ensure these components can still operate normally inside a sealed underwater housing, current engineering solutions typically involve adding a ring gear around the zoom or focus ring. This gear is then connected to an external adjustment mechanism (such as a knob, dial, or push rod) mounted on the waterproof housing wall via gear meshing or friction transmission. When the user rotates or actuates the handle on the outside of the housing, power is transmitted through a sealed shaft to the internal gear, which in turn drives the corresponding adjustment ring to rotate, thus adjusting the lens parameters without compromising the watertightness of the housing.

[0004] However, most adjustment mechanisms currently on the market can only control a single gear independently—either driving the zoom gear ring or the focus gear ring, without interference. When photographic tasks require separate adjustments to focal length and focus (such as tracking fast-moving marine life or zooming from a wide-angle perspective to a macro close-up), photographers often need to operate two independent adjustment units. This forces waterproof housing designers to install two or more independent drive systems. Each system includes external adjustment knobs, sealing shafts, internal gears, and positioning brackets, significantly increasing the internal space occupied by the housing and the number of sealing interfaces, thus increasing the risk of leakage. Even more problematic is the extremely limited internal capacity of the waterproof housing, which must also accommodate the camera body, storage units, and cables. The stacking of unnecessary mechanisms inevitably leads to increased housing size and weight, disrupting the original compact, streamlined design and even affecting the ease of underwater operation and grip.

[0005] Therefore, the current "single-ring, single-drive" adjustment mode has become one of the main bottlenecks in the miniaturization and multi-functionality development of underwater photography equipment. The aforementioned structure has significant shortcomings in terms of space utilization, sealing reliability, and ease of operation. How to achieve zoom and focus adjustment within a limited space is both a real challenge in engineering design and an important direction for the future optimization of underwater photography equipment. Summary of the Invention

[0006] This invention provides a waterproof camera device and its focusing and zoom adjustment mechanism, which solves the problems of space utilization, sealing reliability and ease of operation of the adjustment mechanism.

[0007] In one embodiment, a focusing and zoom adjustment device for a camera waterproof housing is provided, comprising: a mounting base located inside the camera waterproof housing, a first fixed gear rotatably disposed on the mounting base and used to drive a zoom gear on the camera lens to rotate, and a second fixed gear rotatably disposed on the mounting base and used to drive a focusing gear on the camera lens to rotate.

[0008] Also includes:

[0009] A movable component is movably disposed on the mounting base, and the movable component has a first position and a second position on the mounting base;

[0010] A transmission gear is rotatably mounted on the movable component, and the transmission gear moves synchronously with the movable component;

[0011] Adjustment components are located on the outside of the camera's waterproof housing;

[0012] A first transmission component is installed on the mounting base. One end of the first transmission component extends out of the camera waterproof shell and is connected to the adjusting component, and the other end is connected to the transmission gear.

[0013] A switching component, mounted on a camera waterproof housing, is used to drive the movable member to switch between a first position and a second position; when the movable member is in the first position, the transmission gear meshes with the first fixed gear; when the movable member is in the second position, the transmission gear meshes with the second fixed gear.

[0014] In one embodiment, the axis of the first fixed gear is parallel to the axis of the second fixed gear, and the first fixed gear and the second fixed gear are staggered at intervals.

[0015] In one embodiment, the axial width of the transmission gear is greater than the axial distance between the first fixed gear and the second fixed gear.

[0016] In one embodiment, the first transmission assembly includes a first adjusting gear, a second adjusting gear, a third adjusting gear, and an adjusting transmission shaft. The first adjusting gear is mounted on one end of the adjusting transmission shaft and located inside the camera's waterproof housing. The other end of the adjusting transmission shaft passes through the camera's waterproof housing and is connected to the adjusting member. The adjusting member, the adjusting transmission shaft, the first adjusting gear, the second adjusting gear, the third adjusting gear, and the transmission gear are sequentially connected in a transmission manner.

[0017] In one embodiment, the axis of the third adjusting gear is parallel to the axis of the first fixed gear; the axis of rotation of the movable member relative to the mounting base coincides with the axis of the third adjusting gear, and the transmission gear is connected to the third adjusting gear when the movable member is in the first position or the second position.

[0018] In one embodiment, the switching assembly includes a switching element and a second transmission assembly. The switching element is mounted on the outside of the camera's waterproof housing. One end of the second transmission assembly extends out of the camera's waterproof housing and connects to the switching element, while the other end is connected to the movable component in a transmission manner.

[0019] In one embodiment, the second transmission assembly includes a first switching gear, a second switching gear, a third switching gear, a fourth switching gear, a fifth switching gear, and a switching transmission shaft. The first switching gear is mounted on one end of the switching transmission shaft and located inside the camera's waterproof housing. The other end of the switching transmission shaft passes through the camera's waterproof housing and is connected to the switching component. The switching component, the switching transmission shaft, the first switching gear, the second switching gear, the third switching gear, the fourth switching gear, the fifth switching gear, and the movable component are sequentially connected in a transmission manner.

[0020] In one embodiment, at least a portion of the structure of the movable member is an arc-shaped structure, the arc-shaped structure having teeth, and the teeth of the movable member meshing with the fifth switching gear.

[0021] In one embodiment, the switching assembly further includes a first elastic element, one end of which is connected to the mounting base, and the other end of which is connected to the fifth switching gear; when the movable member is in the first position, the first elastic element applies a pulling force to the fifth switching gear to drive the transmission gear toward the first fixed gear; when the movable member is in the second position, the first elastic element applies a pulling force to the fifth switching gear to drive the transmission gear toward the second fixed gear.

[0022] In one embodiment, a waterproof camera device includes:

[0023] Focusing and zoom adjustment devices;

[0024] And a camera waterproof housing having a receiving cavity for accommodating the camera, wherein the focusing and zoom adjustment device is used to adjust the zoom and focus of the camera from the outside of the camera waterproof housing.

[0025] According to the above embodiments, a waterproof camera device and its focusing and zoom adjustment mechanism are disclosed. The focusing and zoom adjustment mechanism includes a first fixed gear for driving the zoom gear on the camera lens to rotate, a second fixed gear for driving the focusing gear on the camera lens to rotate, a movable component, a transmission gear, an adjusting component, a first transmission assembly, and a switching assembly. The switching assembly drives the movable component to switch between a first position and a second position. When the movable component is in the first position, the transmission gear meshes with the first fixed gear. At this time, the adjusting component, the first transmission assembly, the transmission gear, the first fixed gear, and the camera's zoom gear are sequentially connected, allowing the user to adjust the camera's zoom by operating the adjusting component. When the movable component is in the second position, the transmission gear meshes with the second fixed gear. At this time, the adjusting component, the first transmission assembly, the transmission gear, the second fixed gear, and the camera's focusing gear are sequentially connected, allowing the user to adjust the camera's focus by operating the adjusting component. This focusing and zoom adjustment mechanism, through the switching of the switching assembly, enables zoom and focus adjustment of the camera within the waterproof housing, meeting the shooting needs of the camera in various underwater scenarios.

[0026] This focusing and zoom adjustment device uses a switching assembly to drive a transmission gear to switch between a first position and a second position, thereby switching between zoom and focus adjustments. Both zoom and focus adjustments are achieved through a single adjustment assembly consisting of an adjustment component and a first transmission assembly. Compared to using two separate adjustment assemblies for zoom and focus adjustments, this significantly reduces the space occupied by this focusing and zoom adjustment device within the camera's waterproof housing. More importantly, the reduced size of this focusing and zoom adjustment device does not increase the size or weight of the waterproof camera equipment, and does not affect the ease of underwater operation or the feel of holding the waterproof camera.

Detailed Implementation

[0042] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the invention. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present invention are not shown or described in the specification. This is to avoid obscuring the core parts of the invention with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0043] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0044] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this invention, unless otherwise specified, include both direct and indirect connections (linkages).

[0045] In one embodiment, a focusing and zoom adjustment device for a camera waterproof housing is provided. This device is mounted on the camera waterproof housing and is used for focusing and zooming the camera housed within it. It is particularly suitable for underwater environments and can meet the adjustment needs of different shooting scenarios. The core design of this adjustment device integrates focusing and zooming functions into two switchable positions: during use, the user first selects between the "focus position" and the "zoom position" and then performs the corresponding adjustment operation. This position-switching mechanism requires only one set of adjustment components to simultaneously achieve both focusing and zooming functions, completely changing the traditional approach of using two separate adjustment components for focusing and zooming. Compared to the design of two separate components, this adjustment device significantly reduces the internal space occupied by the camera waterproof housing, making installation and layout more flexible and convenient; it does not increase the overall size and weight of the camera waterproof housing, nor does it affect the original internal structure; and it can be directly upgraded from existing products without redesigning the housing, exhibiting strong compatibility and practical value.

[0046] Please refer to Figure 1 , Figure 2 and Figure 3 The focusing and zoom adjustment device 100 in this embodiment mainly includes a mounting base 1, a first fixed gear 2, a second fixed gear 3, a movable component 4, a transmission gear 5, an adjustment component 6, a first transmission assembly 7, and a switching assembly 8.

[0047] Please refer to the details. Figure 12 The mounting base 1 is located inside the camera's waterproof housing 200. The mounting base 1 can be a single integrated component or assembled from multiple parts. The mounting base 1 serves as the base for the focusing and zoom adjustment device 100, and most of the components of the focusing and zoom adjustment device 100 are mounted on the mounting base 1.

[0048] Please refer to the details. Figure 11 For ease of description, the focusing and zoom adjustment device 100 has a first direction, a second direction and a third direction that are perpendicular to each other, wherein the first direction is the lens axis of the camera lens 300, the second direction is the left-right direction of the camera waterproof housing 200, and the third direction is the up-down direction of the camera waterproof housing 200.

[0049] Please refer to the details. Figure 3 The first fixed gear 2 is rotatably mounted on the mounting base 1 and is used to drive the zoom gear 302 on the camera lens 300 to rotate. The first fixed gear 2 is rotatable on the mounting base 1 via a rotating shaft, and the first fixed gear 2 can rotate around the axis of the rotating shaft. The axis of the first fixed gear 2 is parallel to a first direction. When the camera lens 300 is installed inside the camera waterproof housing 200, the axis of the first fixed gear 2 is parallel to the axis of the zoom gear 302 of the camera lens 300. The zoom gear 302 of the camera lens 300 meshes with the first fixed gear 2, and the first fixed gear 2 can drive the zoom gear 302 of the camera lens 300 to rotate, so as to realize zoom adjustment.

[0050] The second fixed gear 3 is rotatably mounted on the mounting base 1 and is used to drive the focusing gear 301 on the camera lens 300 to rotate. The second fixed gear 3 is rotatable on the mounting base 1 via a rotating shaft. The second fixed gear 3 can rotate around the axis of the rotating shaft. The axis of the second fixed gear 3 is parallel to the first direction, and the axis of the first fixed gear 2 is parallel to the axis of the second fixed gear 3. When the camera lens 300 is installed inside the camera waterproof housing 200, the axis of the second fixed gear 3 is parallel to the axis of the focusing gear 301 of the camera lens 300. The focusing gear 301 of the camera lens 300 meshes with the second fixed gear 3, and the second fixed gear 3 can drive the focusing gear 301 of the camera lens 300 to rotate, so as to achieve focus adjustment.

[0051] The first fixed gear 2 and the second fixed gear 3 are used to connect the zoom gear 302 and the focus gear 301 of the camera lens 300, respectively. The zoom gear 302 and the focus gear 301 of the camera lens 300 are coaxial and axially spaced apart, that is, the axial direction of the zoom gear 302 and the axial direction of the focus gear 301 are parallel to the first direction, and the zoom gear 302 and the focus gear 301 are spaced apart along the first direction. Correspondingly, the first fixed gear 2 and the second fixed gear 3 are spaced apart along the first direction, and the first fixed gear 2 and the zoom gear 302 are located in a first plane perpendicular to the first direction, while the second fixed gear 3 and the focus gear 301 are located in a second plane perpendicular to the first direction.

[0052] The first fixed gear 2 and the second fixed gear 3 can rotate relative to the mounting base 1, but the first fixed gear 2 and the second fixed gear 3 cannot move relative to the mounting base 1. The first fixed gear 2 and the second fixed gear 3 have relatively fixed mounting positions so that after the camera lens 300 is installed inside the camera waterproof housing 200, the first fixed gear 2 can mesh with the zoom gear 302 of the camera lens 300, and the second fixed gear 3 can mesh with the focus gear 301 of the camera lens 300.

[0053] Please refer to the details. Figure 1 , Figure 2 The movable component 4 is movably disposed on the mounting base 1, and the movable component 4 is movable relative to the mounting base 1. Specifically, the movable component 4 is rotatable relative to the mounting base 1, and the movable component 4 rotates about an axis parallel to the first direction.

[0054] The transmission gear 5 is rotatably mounted on the movable component 4. The transmission gear 5 is rotatably mounted on the movable component 4 via a rotating shaft. The axial direction of the transmission gear 5 is parallel to the first direction. The transmission gear 5 can rotate relative to the movable component 4, and the movable component 4 can drive the transmission gear 5 to move synchronously.

[0055] The movable component 4 can be moved to a first position and a second position. When the movable component 4 is in the first position, the transmission gear 5 rotates to mesh with the first fixed gear 2. When the movable component 4 is in the second position, the transmission gear 5 rotates to mesh with the second fixed gear 3.

[0056] The adjustment component 6 is located outside the camera waterproof housing 200. The adjustment component 6 can be a knob or other operating component, allowing the user to operate it from outside the camera waterproof housing 200.

[0057] The first transmission assembly 7 is mounted on the mounting base 1. One end of the first transmission assembly 7 extends out of the camera waterproof housing 200 and connects to the adjusting member 6. The other end of the first transmission assembly 7 is connected to the transmission gear 5. Most of the structure of the first transmission assembly 7 is located inside the camera waterproof housing 200, and part of the structure of the first transmission assembly 7 passes through the camera waterproof housing 200 and connects to the adjusting member 6 located on the outside.

[0058] The adjustment component 6 is connected to the transmission gear 5 via the first transmission assembly 7, and the user can adjust the zoom and focus of the camera lens 300 by operating the adjustment component 6.

[0059] The switching assembly 8 is mounted on the camera waterproof housing 200. One end of the switching assembly 8 is located outside the camera waterproof housing 200, and the other end is located inside the camera waterproof housing 200 and connected to the movable member 4. The switching assembly 8 is used to drive the movable member 4 to switch between a first position and a second position. That is, the switching assembly 8 has two positions, and it switches between a focus position and a zoom position.

[0060] Please refer to Figures 4 to 6 When the switching component 8 is switched to the zoom position, the switching component 8 drives the movable component 4 to move to the first position. The movable component 4 drives the transmission gear 5 to move to mesh with the first fixed gear 2, and the transmission gear 5 separates from the second fixed gear 3. At this time, the adjusting component 6, the first transmission component 7, the transmission gear 5, the first fixed gear 2 and the zoom gear 302 of the camera lens 300 are connected in sequence. The user can drive the zoom gear 302 to rotate forward and backward by operating the adjusting component 6 to realize the zoom adjustment of the camera lens 300.

[0061] Please refer to Figures 7 to 9 When the switching component 8 switches to the focus position, the switching component 8 drives the movable component 4 to move to the second position. The movable component 4 drives the transmission gear 5 to move to mesh with the second fixed gear 3, and the transmission gear 5 separates from the first fixed gear 2. At this time, the adjusting component 6, the first transmission component 7, the transmission gear 5, the second fixed gear 3, and the focus gear 301 of the camera lens 300 are sequentially connected. The user can drive the focus gear 301 to rotate forward and backward by operating the adjusting component 6 to adjust the focus of the camera lens 300.

[0062] In this embodiment, the focusing and zooming device includes a first fixed gear 2 for driving the zoom gear 302 on the camera lens 300 to rotate, a second fixed gear 3 for driving the focusing gear 301 on the camera lens 300 to rotate, a movable component 4, a transmission gear 5, an adjusting component 6, a first transmission assembly 7, and a switching assembly 8. The switching assembly 8 is used to drive the movable component 4 to switch between a first position and a second position. When the movable component 4 is in the first position, the transmission gear 5 meshes with the first fixed gear 2, and the user can adjust the zoom of the camera lens 300 by operating the adjusting component 6. When the movable component 4 is in the second position, the transmission gear 5 meshes with the second fixed gear 3, and the user can adjust the focus of the camera by operating the adjusting component 6. This focusing and zooming adjustment device 100, through the switching of the two positions of the switching assembly 8, can realize the zoom and focus adjustment of the camera inside the camera waterproof housing 200, realize dual-focus adjustment, realize more varied composition and sharpness adjustment, and meet the shooting needs of the camera in more different underwater scenes.

[0063] This focusing and zoom adjustment device 100 uses a switching component 8 to drive the transmission gear 5 to switch between a first position and a second position, thereby switching between zoom and focus adjustments. Both zoom and focus adjustments are achieved through a single adjustment component consisting of the adjustment element 6 and the first transmission component 7. Compared to using two separate adjustment components for zoom and focus adjustments, this significantly reduces the space occupied by the focusing and zoom adjustment device 100 within the camera's waterproof housing 200. More importantly, the reduced size of the focusing and zoom adjustment device 100 does not increase the size or weight of the camera's waterproof housing 200, and does not affect the ease of underwater operation or the feel of the grip.

[0064] Please refer to Figure 1 and Figure 2 In one embodiment, the movable member 4 is rotatably mounted on the mounting base 1. At least a portion of the structure of the movable member 4 is an arc-shaped structure with teeth. The teeth of the movable member 4 engage with the switching assembly 8.

[0065] In some embodiments, the movable component 4 is an arc-shaped structure, with the center of the arc serving as the rotation center of the movable component 4. The movable component 4 is rotatably configured so that its rotation drives the transmission gear 5 to switch between a first position and a second position. When rotated to the first position, the transmission gear 5 meshes with the first fixed gear 2; when rotated to the second position, the transmission gear 5 meshes with the second fixed gear 3. The overall arc-shaped structure of the movable component 4, compared to a circular structure, allows for a reduction in its volume and weight while still enabling the transmission gear 5 to switch between the first and second positions, thus minimizing the space occupied by the movable component 4 and avoiding interference with connections between other gears.

[0066] Please refer to Figure 1 and Figure 2 In one embodiment, the movable component 4 is provided with an arc-shaped guide groove 41. The guide groove 41 can be a slot structure that penetrates the movable component 4. The rotation center of the arc-shaped guide groove 41 coincides with the rotation center of the movable component 4. The mounting base 1 is provided with a guide rail 11. The protrusion direction of the guide rail 11 is parallel to the first direction. The guide rail 11 is an arc-shaped boss, and the curvature and width of the arc-shaped boss are adapted to the curvature and width of the guide groove 41. The guide rail 11 is disposed in the guide groove 41. When the movable component 4 is driven to rotate by the switching component 8, the guide rail 11 remains stationary, and the guide groove 41 of the movable component 4 slides relative to the guide rail 11. The guide rail 11 plays a limiting and guiding role, so that the movable component 4 can accurately switch to the first position and the second position.

[0067] One end of the guide rail 11 is fixedly connected to the mounting base 1, or the guide rail 11 and the mounting base 1 are an integrated structure, and the other end of the guide rail 11 is provided with a limiting part 12, so that the movable component 4 cannot be dislodged from the guide rail 11.

[0068] The guide rail 11 is an arc-shaped boss with a certain arc length. With this configuration, when the movable component 4 is switched to the first position, one end of the guide rail 11 abuts against one end of the guide groove 41, forming a mechanical limit on the movable component 4 in the first position, ensuring the accuracy and stability of the meshing between the transmission gear 5 and the first fixed gear 2; when the movable component 4 is switched to the second position, the other end of the guide rail 11 abuts against the other end of the guide groove 41, forming a mechanical limit on the movable component 4 in the second position, ensuring the accuracy and stability of the meshing between the transmission gear 5 and the second fixed gear 3.

[0069] Please refer to Figure 1 The limiting part 12 includes a screw and a washer. The outer diameter of the washer is larger than the width of the guide groove 41. The screw passes through the washer and is threaded to the guide rail 11. The screw and the washer limit the movable member 4 on the mounting base 1, limiting the degree of freedom of the movable member 4 relative to the mounting base 1 in the first direction.

[0070] Please refer to Figure 1 and Figure 2 In one embodiment, the movable member 4 is provided with multiple arc-shaped guide grooves 41, which are distributed on the same circumference, the center of which coincides with the rotation center of the movable member 4. For example, the movable member 4 is provided with two arc-shaped guide grooves 41, and a guide rail 11 is installed in each guide groove 41. With this arrangement, the sliding cooperation between the multiple guide grooves 41 and the guide rails 11 can improve the rotational stability of the movable member 4; furthermore, a solid part (not shown) can be formed between the multiple guide grooves 41 to install the transmission gear 5.

[0071] In one embodiment, the overall shape of the movable component 4 can also be a ring or a circular disc structure, which can also drive the transmission gear 5 to switch to the first position and the second position.

[0072] Please refer to Figure 5 and Figure 7 In one embodiment, the axial thickness of the transmission gear 5 is greater than the distance between the axes of the first fixed gear 2 and the second fixed gear 3. Specifically, in the first direction, the thickness of the transmission gear 5 is greater than the distance between the first fixed gear 2 and the second fixed gear 3. This arrangement allows the transmission gear 5 to connect with the first fixed gear 2 when it rotates to the first position with the movable member 4, and to connect with the second fixed gear 3 when it rotates to the second position with the movable member 4. That is, the transmission gear 5 can connect with the first fixed gear 2 and the second fixed gear 3, which are spaced apart in the first direction, without needing to move in the first direction. In one embodiment, the first fixed gear 2 has a first side facing away from the second fixed gear 3, and the second fixed gear 3 has a second side facing away from the first fixed gear 2. In the first direction, the thickness of the transmission gear 5 is greater than or equal to the distance between the first side of the first fixed gear 2 and the second side of the second fixed gear 3. This configuration allows the transmission gear 5 to mesh with the full tooth surface of the first fixed gear 2 in the first position, and to mesh with the full tooth surface of the second fixed gear 3 in the second position. This effectively improves the stability and accuracy of the meshing transmission, thereby enhancing the stability and accuracy of zoom adjustment and focus adjustment.

[0073] In one embodiment, the movable member 4 may be provided with two transmission gears 5 spaced apart along a first direction. The two transmission gears 5 include a first transmission gear (not shown) and a second transmission gear (not shown). In the first direction, the distance between the first transmission gear and the second transmission gear is the same as the distance between the first fixed gear 2 and the second fixed gear 3. When the movable member 4 rotates to a first position, the first transmission gear is connected to the first fixed gear 2, and the second transmission gear is separated from the second fixed gear 3. When the movable member 4 rotates to a second position, the first transmission gear is separated from the first fixed gear 2, and the second transmission gear is connected to the second fixed gear 3. With this configuration, the movable member 4 can drive the two different transmission gears 5 to connect to the first fixed gear 2 and the second fixed gear 3 respectively, and can also realize the switching between zoom adjustment and focus adjustment.

[0074] In one embodiment, the movable member 4 is movably mounted on the mounting base 1 along a first direction. The mounting base 1 has a mounting hole or mounting groove (not shown) extending along the first direction. The movable member 4 is a movable column (not shown) extending along the first direction, which can be slidably inserted into the mounting hole or mounting groove. The movable member 4 switches between a first position and a second position by moving along the first direction. Correspondingly, the switching component 8 is configured as a linear movement driving component. For example, the switching component 8 is configured as a push-button switch structure. After a single press, the switching component 8 sinks down, driving the movable member 4 to move along the first direction to the first position. After pressing the switching component 8 again, the switching component 8 springs back to its original position and drives the movable member 4 to move along the first direction to the second position. With this configuration, the switching component 8 can also drive the movable member 4 to move the transmission gear 5 to connect with the first fixed gear 2, and to move the transmission gear 5 to connect with the second fixed gear 3, thereby realizing the switching between zoom adjustment and focus adjustment.

[0075] Please refer to Figure 1 and Figure 2 In one embodiment, the first transmission assembly 7 includes a first adjusting gear 71, a second adjusting gear 72, a third adjusting gear 73, and an adjusting transmission shaft 74. The first adjusting gear 71 is installed at one end of the adjusting transmission shaft 74 and is located inside the camera waterproof housing 200. The other end of the adjusting transmission shaft 74 passes through the camera waterproof housing 200 and is connected to the adjusting member 6. The first adjusting gear 71, the second adjusting gear 72, and the third adjusting gear 73 are rotatably mounted on the mounting base 1 via rotating shafts.

[0076] Adjusting component 6, adjusting drive shaft 74, first adjusting gear 71, second adjusting gear 72, third adjusting gear 73, and transmission gear 5 are sequentially connected for transmission. Adjusting component 6 is fixedly connected to one end of adjusting drive shaft 74, and the other end of adjusting drive shaft 74 is fixedly connected to first adjusting gear 71. First adjusting gear 71 and second adjusting gear 72 mesh, second adjusting gear 72 and third adjusting gear 73 are coaxially fixed, and third adjusting gear 73 meshes with transmission gear 5.

[0077] The axis of the first adjusting gear 71 is parallel to the second direction, and the axes of the second adjusting gear 72 and the third adjusting gear 73 are parallel to the first direction, and the axes of the second adjusting gear 72 and the third adjusting gear 73 coincide. The first adjusting gear 71 and the second adjusting gear 72 are mutually cooperating helical gears or spiral gears. The first adjusting gear 71 and the second adjusting gear 72 form a helical gear or spiral gear set to convert the rotational joint of the adjusting member 6 about the second direction into a rotational joint about the first direction, so as to drive the focusing gear 301 and zoom gear 302 on the camera lens 300 to rotate about the first direction.

[0078] The adjustment drive shaft 74 is equipped with a sealing structure such as a sealing ring. The sealing structure is locked in the first mounting hole (not shown) of the camera waterproof housing 200 to seal the first mounting hole through which the adjustment drive shaft 74 passes, thereby playing a sealing and protection role to prevent water from entering the camera waterproof housing 200 through the first mounting hole through which the adjustment drive shaft 74 passes during underwater photography.

[0079] The movable component 4 is rotatably mounted on the mounting base 1. The rotation axis of the movable component 4 coincides with the axis of the third adjusting gear 73. This allows the transmission gear 5 to be located at different circumferential positions of the third adjusting gear 73 when the movable component 4 is switched to the first position and the second position, and the transmission gear 5 is always engaged with the third adjusting gear 73. More importantly, during the rotation of the movable component 4, the transmission gear 5 can roll along the circumferential edge of the third adjusting gear 73. The transmission gear 5 is always engaged with the third adjusting gear 73 and the two never separate. This ensures that when the movable component 4 is switched to the first position and the second position, the transmission gear 5 and the third adjusting gear 73 form a stable meshing state, ensuring the stability of the transmission. Furthermore, the third adjusting gear 73 can provide guidance for the movement of the transmission gear 5, allowing the transmission gear 5 to move more accurately to the first position and the second position.

[0080] The first transmission component 7 uses a combination of a rotating shaft and a gear set, which enables the first transmission component 7 to change the transmission direction of torque. This allows the adjustment component 6 to be set on the side wall of the camera waterproof housing 200 in the second direction. The rotational torque input to the adjustment component 6 around the second direction can ultimately drive the zoom gear 302 and the focus gear 301 rotating around the first direction. The adjustment component 6 is located on the upper left or right side of the camera waterproof housing 200, close to the handles on the left and right sides of the camera waterproof housing 200, so that the user can operate the adjustment component 6 while holding the handle. This provides greater operational convenience, especially underwater, allowing the user to hold the camera stably while adjusting the zoom and focus to capture the desired image.

[0081] In one embodiment, the second adjusting gear 72 and the third adjusting gear 73 are mounted on the same rotating shaft so that the axis of the second adjusting gear 72 and the axis of the third adjusting gear 73 coincide, thus ensuring the accuracy of transmission.

[0082] In one embodiment, the second adjusting gear 72 and the third adjusting gear 73 have the same axis and can be configured as an integrated structure, meaning they are machined from a single component. This arrangement reduces the need for coaxial installation of the second adjusting gear 72 and the third adjusting gear 73, ensuring their coaxiality through machining. Compared to the installation method, the machining method offers higher precision and greater stability.

[0083] In one embodiment, the first transmission assembly 7 may also include other transmission structures. For example, the first transmission assembly 7 includes a third adjusting gear 73 and an adjusting transmission shaft 74, with the adjusting member 6, adjusting transmission shaft 74, third adjusting gear 73, and transmission gear 5 sequentially connected. In this scheme, helical gears or spiral gear sets are not provided, and the adjusting transmission shaft 74 is directly connected to the third adjusting gear 73. With this configuration, the adjusting member 6 is located on the side wall of the camera waterproof housing 200 in the first direction, which can also realize zoom and focus adjustment of the camera lens 300.

[0084] Please refer to Figure 1 and Figure 2 In one embodiment, the switching assembly 8 drives the movable member 4 to rotate via a pivot to switch between a first position and a second position. The switching assembly 8 includes a switching element 81 and a second transmission assembly 82. The switching element 81 is mounted on the outside of the camera waterproof housing 200. One end of the second transmission assembly 82 extends out of the camera waterproof housing 200 and is connected to the switching element 81. The other end of the second transmission assembly 82 is connected to the movable member 4 via the transmission assembly 82. The switching element 81 drives the movable member 4 to switch between the first position and the second position via the second transmission assembly 82.

[0085] The switch 81 is a lever, which makes it convenient for users to switch gears. Users can easily switch the switch 81 to the focus mode and zoom mode.

[0086] The switching element 81 can also be other structures, such as a knob, which allows the user to switch between focus and zoom levels.

[0087] Please refer to Figure 1 and Figure 2 In one embodiment, the second transmission assembly 82 includes a first switching gear 821, a second switching gear 822, a third switching gear 823, a fourth switching gear 824, a fifth switching gear 825, and a switching transmission shaft 826. The first switching gear 821 is mounted on one end of the switching transmission shaft 826 and located inside the camera waterproof housing 200. The other end of the switching transmission shaft 826 passes through the camera waterproof housing 200 and is connected to the switching member 81. The switching member 81, the switching transmission shaft 826, the first switching gear 821, the second switching gear 822, the third switching gear 823, the fourth switching gear 824, the fifth switching gear 825, and the movable member 4 are sequentially connected in a transmission manner. The switching member 81 and the switching transmission shaft 826 are coaxially fixedly connected. The first switching gear 821 meshes with the second switching gear 822, the third switching gear 823 meshes with the fourth switching gear 824, the fourth switching gear 824 and the fifth switching gear 825 are coaxially fixedly connected, and the fifth switching gear 825 meshes with the movable member 4.

[0088] The axes of the switching drive shaft 826, the first switching gear 821, the second switching gear 822, and the third switching gear 823 are all parallel to the second direction, while the axes of the fourth switching gear 824 and the fifth switching gear 825 are parallel to the first direction. The switching drive shaft 826 is equipped with a sealing ring or other sealing structure, which is fitted into the second mounting hole (not shown) of the camera's waterproof housing 200 to seal the second mounting hole through which the switching drive shaft 826 passes, thus providing a sealing protection to prevent water from entering the camera's waterproof housing 200 through the second mounting hole during underwater photography.

[0089] The third switching gear 823 and the fourth switching gear 824 are mutually cooperating helical gears or spiral gears. The helical gear or spiral gear set composed of the third switching gear 823 and the fourth switching gear 824 is used to change the transmission direction of torque. The helical gear or spiral gear set composed of the third switching gear 823 and the fourth switching gear 824 is used to convert the torque input by the switching element 81 rotating about the second direction into a torque rotating about the first direction, and drive the movable member 4 rotating about the first direction through the torque rotating about the first direction, so as to drive the movable member 4 to rotate to the first position and the second position. With this configuration, the switching element 81 can also be set on the side wall of the camera waterproof housing 200 in the second direction. The switching element 81 is located on the lower left or right side of the camera waterproof housing 200, close to the handles on the left and right sides of the camera waterproof housing 200, so that the user can operate the switching element 81 when holding the handle, which provides greater operational convenience, especially underwater, allowing the user to hold the camera stably while switching between zoom and focus adjustment to capture the desired image. Furthermore, the switch 81 and the adjustment 6 can be placed on the same side of the camera waterproof housing 200, and the two can be placed close to each other, so that the user can perform gear switching and adjustment operations with one hand, making the operation more convenient.

[0090] In one embodiment, the second switching gear 822 and the third switching gear 823 are mounted on the same rotating shaft, and / or the fourth switching gear 824 and the fifth switching gear 825 are mounted on the same rotating shaft. This mounting ensures that the axes of the second switching gear 822 and the third switching gear 823 coincide, and the axes of the fourth switching gear 824 and the fifth switching gear 825 coincide, thereby ensuring the accuracy of the transmission.

[0091] In one embodiment, the second switching gear 822 and the third switching gear 823 are an integrated structure, and are machined from a single component; and / or, the fourth switching gear 824 and the fifth switching gear 825 are an integrated structure, and are machined from a single component. This configuration ensures the coaxiality of the second switching gear 822 and the third switching gear 823, as well as the coaxiality of the fourth switching gear 824 and the fifth switching gear 825, through machining. Compared to the installation method, this machining method offers higher precision and greater stability.

[0092] In one embodiment, one or more of the fourth switching gear 824, the fifth switching gear 825, and the movable member 4 include a partial tooth structure. Preferably, the fourth switching gear 824, the fifth switching gear 825, and the movable member 4 are all configured with partial tooth structures, that is, the fourth switching gear 824, the fifth switching gear 825, and the movable member 4 each include an arc-shaped tooth section, and the central angle of the arc is larger than the central angle of rotation required for switching between the focus position and the zoom position. With this configuration, the fourth switching gear 824, the fifth switching gear 825, and the movable member 4, while ensuring the switching requirements between the focus position and the zoom position, minimize their respective size and weight, making it easier to arrange the focus and zoom adjustment device 100 within the camera waterproof housing 200, and also reducing the overall size and weight of the camera waterproof housing 200.

[0093] In one embodiment, one or more of the fourth switching gear 824, the fifth switching gear 825, and the movable member 4 can also be configured as circular gear structures. For example, the fourth switching gear 824, the fifth switching gear 825, and the movable member 4 can all be configured as circular gear structures. This configuration can also meet the switching requirements between focus and zoom modes.

[0094] Please refer to Figure 1 and Figure 2 In one embodiment, the switching component 8 further includes a first elastic element 83. One end of the first elastic element 83 is connected to the mounting base 1, and the other end of the first elastic element 83 is connected to the fifth switching gear 825. The first elastic element 83 is connected to the fifth switching gear near its edge. Please refer to [reference needed]. Figure 6 When the movable component 4 is in the first position, the movable component 4 drives the first elastic element 83 to move, the first elastic element 83 is stretched, and the first elastic element 83 applies a pulling force to the fifth switching gear 825, so as to drive the transmission gear 5 to move towards the first fixed gear 2; please refer to Figure 9When the movable component 4 is in the second position, the movable component 4 drives the first elastic element 83 to move, and the first elastic element 83 is also stretched. The first elastic element 83 applies a pulling force to the fifth switching gear 825, so as to drive the transmission gear 5 to move towards the second fixed gear 3. The first elastic element 83 can be a cylindrical spring.

[0095] When the movable component 5 switches to the first or second position, the end of the guide rail 11 engages with the guide groove 41 to form a mechanical limit. The preload applied by the first elastic element 83 to the movable component 4 can accurately lock the movable component 4 and the transmission gear 5 to the first or second position. In addition, adjusting the tension value of the first elastic element 83 can resist the friction and reaction force of the lens during focus or zoom adjustment, preventing it from slipping or slipping. Furthermore, when the transmission gear 5 is misaligned or teeth are misaligned with the first fixed gear 2 or the second fixed gear 3, the shifting process is paused. At this time, rotating the adjusting element 6 can drive the transmission gear 5 to rotate until it is fully aligned with the first fixed gear 2 or the second fixed gear 3. Then, under the tension of the first elastic element 83, it moves to the first or second position on its own, forming an automatic return position, ensuring the smoothness and accuracy of the movable component 5 switching to the first and second positions.

[0096] Please refer to Figure 10 In one embodiment, the outer wall of the camera's waterproof housing 200 is provided with a first limiting part 202, such as a limiting groove, and the switching member 81 is rotatably located within this limiting groove. When the switching member 81 rotates to contact the side wall at one end of the limiting groove, the switching member 81 switches to the focus position; when the switching member 81 rotates to contact the side wall at the other end of the limiting groove, the switching member 81 switches to the zoom position. With this configuration, the limiting groove positions the switching member 81, allowing it to switch more accurately between the focus and zoom positions. The user only needs to push the switching member 81 all the way in different directions to quickly and accurately switch between the focus and zoom positions.

[0097] Please refer to Figure 2In one embodiment, in the third direction, the mounting base 1 can be an L-shaped support plate structure. The mounting base 1 has a first mounting plate 1a perpendicular to the first direction, a second mounting plate 1b perpendicular to the second direction, and a third mounting plate 1c perpendicular to the second direction. The mounting base 1 is an integrally formed structure. Movable component 4, second adjusting gear 72, third adjusting gear 73, fourth switching gear 824, and fifth switching gear 825 are mounted on the first mounting plate 1a. The first adjusting gear 71 and adjusting transmission shaft 74 are mounted on the second mounting plate 1b. The second switching gear 822 and third switching gear 823 are mounted on the third mounting plate 1c. The switching transmission shaft 826 is mounted on the camera waterproof housing, and the first switching gear 821 is mounted on the switching transmission shaft 826. With this configuration, the mounting base 1, by mounting components through the perpendicular first mounting plate 1a, second mounting plate 1b, and third mounting plate 1c, can ensure the parallelism and perpendicularity between components mounted on the mounting base 1, improving installation accuracy and ensuring the stability and accuracy of transmission.

[0098] In one embodiment, the mounting base 1 is movably installed inside the camera waterproof housing 200. The mounting base 1 can move forward and backward along a second direction. When the mounting base 1 moves forward along the second direction, it moves towards the inside of the camera waterproof housing 200; when the mounting base 1 moves backward along the second direction, it moves towards the outside of the camera waterproof housing 200. Furthermore, the mounting base 1 can drive the entire focusing and zoom adjustment device 100 to move forward and backward along the second direction. This configuration allows the focusing and zoom adjustment device 100 to avoid obstructing the installation of the camera lens 300, preventing the camera lens 300 from being improperly installed due to misalignment between the first fixed gear 2 and the zoom gear 302 or between the second fixed gear 3 and the focusing gear 301.

[0099] Specifically, when the camera lens 300 needs to be inserted for installation or removed for disassembly, the mounting base 1 can move relative to the camera waterproof housing 200 to a clearance position and a connection position. In the clearance position, the mounting base 1 moves a certain distance towards the outside of the camera waterproof housing 200, the first fixed gear 2 separates from the zoom gear 302, and the second fixed gear 3 separates from the focusing gear 301. At this time, the camera lens 300 can be freely inserted or removed. After the camera lens 300 is inserted for installation, the mounting base 1 moves a certain distance towards the inside of the camera waterproof housing 200, the first fixed gear 2 engages with the zoom gear 302, and the second fixed gear 3 engages with the focusing gear 301. At this time, the focusing and zoom adjustment device 100 can realize zoom adjustment and focus adjustment of the camera lens 300. As the mounting base 1 moves toward the inside of the camera's waterproof housing 200, the operable adjusting member 6 drives the first fixed gear 2 and the second fixed gear 3 to rotate, so that the first fixed gear 2 is aligned with the zoom gear 302 and the second fixed gear 3 is aligned with the focus gear 301, thus avoiding tooth collision between the first fixed gear 2 and the zoom gear 302 or between the second fixed gear 3 and the focus gear 301.

[0100] Please refer to Figure 1 and Figure 2 In one embodiment, the focusing and zoom adjustment device 100 further includes a clearance component 9, which includes an operating member 91, a fixing member 92, and a second elastic member 93. The operating member 91 and the fixing member 92 are used to install on the outside of the camera waterproof housing 200. The operating member 91 and the fixing member 92 are annular structures, sleeved on the adjustment drive shaft 74, and located between the adjusting member 6 and the outer wall of the camera waterproof housing 200. The fixing member 92 is installed on the outside of the camera waterproof housing 200, and the operating member 91 is located between the fixing member 92 and the outer wall of the camera waterproof housing 200, and the operating member 91 can rotate relative to the fixing member 92. The second elastic member 93 is used to install inside the camera waterproof housing 200. One end of the second elastic member 93 is connected to the inner wall of the camera waterproof housing 200, and the other end of the second elastic member 93 is connected to the mounting base 1. The second elastic member 93 is a straight spring extending in a second direction.

[0101] The operating member 91 has multiple wedge-shaped protrusions 911 spaced apart on a circumference on its side facing the fixing member 92. The outer ring of the fixing member 92 has elastic portions 921 in the same number as the wedge-shaped protrusions 911. A receiving portion (not shown) is formed between adjacent elastic portions 921, and the wedge-shaped protrusions 911 are located within the receiving portion.

[0102] The avoidance component 9 has an avoidance position and a connection position, and the avoidance component 9 can switch between the avoidance position and the connection position by rotation.

[0103] When switching from the connected position to the avoidance position, the user operates the operating component 91 to rotate. The wedge-shaped protrusion 911 of the operating component 91 disengages from the receiving part and presses against the protrusion 922 next to the receiving part. After the protrusion 922 deforms, it presses against the operating component 6. The operating component 6 moves outward along the second direction towards the camera waterproof housing 200, thereby driving the entire focusing and zoom adjustment device 100 to move outward along the second direction towards the camera waterproof housing 200. The first fixed gear 2 separates from the zoom gear 302 of the camera lens 300, the second fixed gear 3 separates from the focusing gear 301 of the camera lens 300, and the second elastic member 93 is compressed to store elastic force. At this time, the avoidance component 9 is in the avoidance position, and the entire focusing and zoom adjustment device 100 avoids the camera lens 300. The camera lens 300 can be freely inserted into or pulled out of the camera waterproof housing 200.

[0104] When switching from the avoidance position to the connection position, the user operates the operating component 91 to rotate in the opposite direction. The wedge-shaped protrusion 911 of the operating component 91 returns to its original position and enters the receiving part. The elastic part 921 releases the squeezing force, causing the operating component 91 to move inward along the second direction toward the inside of the camera waterproof housing 200. The second elastic component 93 releases the stored elastic force to drive the mounting base 1 to move inward along the second direction toward the inside of the camera waterproof housing 200, thereby driving the entire focusing and zoom adjustment device 100 to move inward along the second direction toward the inside of the camera waterproof housing 200. The first fixed gear 2 meshes with the zoom gear 302 of the camera lens 300, and the second fixed gear 3 meshes with the focusing gear 301 of the camera lens 300, achieving automatic return to its original position. At this time, the avoidance component 9 is in the connection position, and the focusing and zoom adjustment device 100 can switch between focusing and zooming on the camera lens 300, as well as perform zoom adjustment and focus adjustment.

[0105] Please refer to Figure 2 In one embodiment, the operating member 91 is provided with a radially protruding operating part 912 in the circumferential position. The radially outward protrusion of the operating part 912 makes it easier for the user to access the operating member 91 and facilitates the user's operation. Furthermore, the radially outward protruding operating part 912 also has an extended operating lever arm, allowing the user to apply less force to drive the operating member 91 to switch between the connection position and the avoidance position.

[0106] Please refer to Figure 10In one embodiment, the outer wall of the camera waterproof housing 200 is provided with a second limiting part 203, such as a limiting groove, and the operating part 912 of the operating member 91 is rotatably located within the limiting groove. When the operating member 91 rotates to the point where the operating part 912 contacts the side wall at one end of the limiting groove, the operating member 91 switches to the avoidance position; when the operating member 91 rotates to the point where the operating part 912 contacts the side wall at the other end of the limiting groove, the operating member 91 switches to the connection position. With this configuration, the limiting groove positions the operating member 91, allowing the operating member 91 to switch more accurately between the avoidance and connection positions. The user only needs to move the operating member 91 to quickly and accurately switch between the avoidance and connection positions.

[0107] Please refer to Figure 6 In one embodiment, multiple second elastic elements 93 may be provided, distributed around the adjustment drive shaft 74. This arrangement provides greater elastic force to drive the entire focusing and zoom adjustment device 100 from the avoidance position to the connection position, making the switching process faster and more stable.

[0108] In one embodiment, the focusing and zoom adjustment device 100 further includes two first guide structures 13, which are bolted to the inside of the camera waterproof housing to guide the mounting base 1 to move smoothly relative to the camera waterproof housing 200 along a second direction.

[0109] Please refer to Figure 5 and Figure 8 Two first guide structures 13 are located on the upper and lower sides of the mounting base 1 in the third direction, respectively. The first guide structure 13 includes a limiting block that contacts the mounting base 1 and bolts for fixing the limiting block to the inner wall of the camera waterproof housing 200. The limiting block guides the focusing and zoom adjustment device 100 to move smoothly in the second direction, so as to achieve a smooth switch between the avoidance position and the connection position. In particular, it ensures that when moving to the connection position, the first fixed gear 2 aligns with the zoom gear 302 to form accurate engagement, and the second fixed gear 3 aligns with the focus gear 301 to form accurate engagement, thus ensuring the stability and accuracy of zoom adjustment and focus adjustment.

[0110] Please refer to Figures 10 to 12 In one embodiment, a camera waterproofing device is provided, which includes the focusing and zoom adjustment device 100 and the camera waterproof housing 200 in any of the above embodiments.

[0111] Please refer to the details. Figure 11The camera housing 200 has a cavity 301 inside. The camera housing 200 has an openable rear cover on its rear side in a first direction, which is the forward / backward direction for shooting. The camera lens 203 faces the first direction and is used for shooting. The camera lens 300 can be installed into or removed from the camera housing 200 by opening the rear cover. When the rear cover is closed, the camera housing 200 forms a completely sealed cavity 301, preventing water from entering and damaging the camera and camera lens 300 during underwater shooting. The camera housing 200 also has a transparent glass on its front side in the first direction, allowing shooting through the glass after the camera lens 300 is installed inside.

[0112] In this embodiment, the adjustment component 6 and the switching component 81 of the focus and zoom adjustment device 100 are located on the outside of the camera waterproof housing 200. When the user takes pictures underwater using the camera waterproof equipment, he / she can switch between the focus mode and the zoom mode through the switching component 81, and make corresponding focus or zoom adjustments through the adjustment component 6.

However, those skilled in the art will recognize that changes and modifications can be made to the exemplary embodiments without departing from the scope of this document. For example, various operational steps and components for performing operational steps can be implemented in different ways depending on the specific application or considering any number of cost functions associated with the operation of the system (e.g., one or more steps can be deleted, modified, or combined with other steps).
