A switching device

Abstract

This invention discloses a switching device, including a body, a switching component, an operating component, and a transmission component. The switching component is adapted to slide relative to the body along a first direction to change the state of the body. The operating component is rotatably connected to the body about a first axis perpendicular to the first direction, and has a first abutment surface and a second abutment surface that are inclined relative to and facing each other in a second direction perpendicular to the first direction and the first axis, forming a first gap between the first abutment surface and the second abutment surface. The transmission component is rotatably connected to the body about a second axis parallel to the first axis and is used to drive the switching component to slide. It has a force-receiving part, which is placed in the first gap and is pushed by the first abutment surface or the second abutment surface to slide within the first gap, causing the transmission component to rotate about the second axis. This method changes the sliding direction of the switching component through the transmission component, thereby making the radial dimension of the body smaller. When applied to a shower head, it can make the radial dimension of the handle smaller and easier to grip.

Description

Technical Field

[0001] This invention relates to the field of aquatic products, and more specifically to a switching device. Background Technology

[0002] In the prior art, a shower head includes a button, a switching element, and a main body. The main body has two water outlet modes and a handle for holding. Water enters through the handle along the axial direction. The button is mounted on the handle and is rotatably connected to the handle and the switching element. When the button is rotated, the button drives the switching element to move radially perpendicular to the axial direction, thereby changing the water outlet state of the main body. When switching in this way, at least two water outlets need to be provided radially on the handpiece, so the radial length of the handle needs to be large enough, that is, the handle will become thick and inconvenient to hold. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a switching device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Option 1: A switching device, comprising...

[0006] ontology;

[0007] A switching element adapted to slide relative to the body along a first direction to change the water outlet state of the body;

[0008] An operating component is rotatably connected to the body about a first axis perpendicular to the first direction. It has a first abutting surface and a second abutting surface that are inclined relative to a second direction perpendicular to the first direction and the first axis and are arranged facing each other. A first gap is formed between the first abutting surface and the second abutting surface.

[0009] A transmission component is rotatably connected to the body about a second axis parallel to the first axis and is used to drive the switching component to slide. It is provided with a force-receiving part, which is placed in the first gap and is pushed by the first abutting surface or the second abutting surface to slide in the first gap, and causes the transmission component to rotate about the second axis.

[0010] Option 2, based on Option 1, involves the connection point between the transmission component and the switching component in the second direction being located between the force-bearing part and the second axis.

[0011] Option 3, based on Option 1, involves the first gap being located between the first axis and the second axis.

[0012] Option 4, based on Option 1, the main body is provided with a guide hole extending along a first direction; the transmission component is provided with a second gap and a sliding groove that are inclined relative to the first direction and pass through the transmission component, the sliding groove communicating with the second gap; the switching component is provided with a switching part and a pushing part, and the pushing part is placed in the second gap and pushed by one of the two side walls of the second gap to slide along the first direction, the switching part passes through the sliding groove and is guided and cooperated with the guide hole along the first direction, and the switching part changes the state of the main body when it slides along the first direction with the pushing part.

[0013] Option 5, based on Option 4, the main body is provided with a first water outlet, a second water outlet, and a water passage cavity extending along a first direction. The water passage cavity is provided with a water inlet and a first water branch and a second water branch communicating with the water inlet. The first water branch and the second water branch are respectively connected to the first water outlet and the second water outlet. The switching component is adapted to slide along the first direction to block the first water branch or the second water branch.

[0014] Option 6, based on Option 5, further includes a reset component, which acts along a first direction on the cavity wall of the water passage chamber and the switching component, and is configured to drive the switching component to block one of the first water outlet and the second water outlet when the water passage chamber is not flowing.

[0015] Option 7, based on Option 5, the main body includes a water outlet component and a spindle; the guide hole is provided on the spindle, the spindle is rotatably connected to the operating component around a first axis, the transmission component is rotatably connected to the spindle around a second axis, the water outlet component is detachably connected to the spindle and surrounds the water passage cavity, and the first water outlet and the second water outlet are provided on the water outlet component.

[0016] Option 8, based on Option 6, has an obtuse angle between the first gap and the second gap, and this angle gradually increases during the process from the switching component blocking the second water outlet to the switching component blocking the first water outlet.

[0017] Option 9, based on Option 1, wherein the force-bearing part is an elastic protrusion.

[0018] Option 10, based on Option 9, wherein the first gap is a hole-like structure having an opening in its extending direction or a hole-like structure not having an opening in its extending direction.

[0019] Option 11, based on Option 5, uses the switching component blocking the second water outlet as the first state and the switching component blocking the first water outlet as the second state. In the first state, the angle between the first gap and the second gap is α1, and the angle between the line connecting the highest point of the rightmost end of the operating component along the first direction and the first axis and the horizontal line parallel to the first direction is β1. In the second state, the angle between the line connecting the first gap and the second gap is α2, and the angle between the line connecting the highest point of the rightmost end of the operating component along the first direction and the first axis and the horizontal line parallel to the first direction is β2. Wherein, α1 is 83.87°-111.13°, β1 is 17.26°-19.65°, α2 is 107.22°-133.22°, and β2 is 8.92°-9.05°.

[0021] Scheme thirteen, based on scheme eleven, has α1 of 83.87°, β1 of 17.26°, α2 of 107.22°, and β2 of 8.92°.

[0022] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Option 1: The switching component is adapted to slide relative to the body along a first direction to change the state of the body;

[0024] The operating component is rotatably connected to the main body about a first axis perpendicular to the first direction. It has a first abutting surface and a second abutting surface that are inclined relative to the second direction and face each other, forming a first gap between the first abutting surface and the second abutting surface. The transmission component is rotatably connected to the main body about a second axis parallel to the first axis and has a force-receiving part. The force-receiving part is placed in the first gap and slides in the first gap by being pushed by the first abutting surface or the second abutting surface. When the operating component rotates about the first axis, the first abutting surface, the second abutting surface and the first gap also rotate about the first axis, and their positions change. Therefore, the force-receiving part will be pushed by the first abutting surface or the second abutting surface and slide in the first gap. At the same time as the force-receiving part slides, it rotates about the second axis, so that the entire transmission component rotates about the second axis. Then, the rotation of the transmission component drives the switching component to slide along the first direction, thereby realizing the state switching of the main body. This method changes the sliding direction of the switching component through the transmission component, so that the radial dimension of the main body can be smaller. When applied to a shower head, it can make the radial dimension of the handle smaller and easier to grip.

[0025] 2. Option 2: In the second direction, the connection point between the transmission component and the switching component is located between the force-bearing part and the second axis, thereby forming a force-saving lever structure, which is more convenient for users to use.

[0026] 3. Option 3: The first gap is located between the first axis and the second axis, which makes the layout more compact, reduces the space occupied, and reduces the installation difficulty and body length.

[0027] 4. Option 4: The main body is provided with a guide hole extending along the first direction. The switching part is guided and engaged with the guide hole along the first direction. Therefore, the switching part will not rotate with the transmission part because it is restricted by the guide hole. When the transmission part rotates, the position of the pushing part in the second gap changes, and the position of the switching part in the slide groove changes. This allows the transmission part to rotate while the pushing part slides along the first direction only when it is pushed by one of the two side walls of the second gap. This allows the switching part to slide along the first direction.

[0028] 5. Option 5: The switching component is adapted to slide along the first direction to block the first or second water outlet, thereby switching the water output of the first and second water outlets. Users can switch according to their water output needs.

[0029] 6. Option Six: The reset component acts on the cavity wall and the switching component along the first direction, and is configured to drive the switching component to block one of the first and second water outlets when the water outlet is not flowing, so that the state is unique when the water is turned off, which is convenient for the user to use the mode frequently used next time and reduces switching operations.

[0030] 7. Option 7: The main body includes a water outlet component and a spindle; a guide hole is provided on the spindle, the spindle is rotatably connected to the operating component around the first axis, the transmission component is rotatably connected to the spindle around the second axis, the water outlet component is detachably connected to the spindle and surrounds it to form a water passage cavity, and the first water outlet and the second water outlet are provided on the water outlet component, thereby facilitating the installation of the switching component and the processing of the water passage.

[0031] 8. Option 8: Since the second water outlet is always blocked initially, the angle between the line connecting the first gap and the second gap is an obtuse angle, and this angle gradually increases during the switching process. Therefore, it becomes increasingly easier to press the operating component, making it more convenient to use. When the water passage is not filled, the switching component automatically resets to block the second water outlet, and the user does not need to press it again. Even if more force is required when switching from blocking the first water outlet to blocking the second water outlet, this force is provided by the reset component, and the user does not need to operate it.

[0032] 9. Option Nine: The force-bearing part is an elastic protrusion. The elastic protrusion has a certain degree of flexibility, is not easy to get stuck, and can easily slide within the first gap.

[0033] 10. Option 10: The first gap can be a hole with an opening in its extending direction. This method facilitates assembly with the transmission component. The force-bearing part of the transmission component can be directly inserted into the first gap through the opening, or it can be a hole without an opening in its extending direction. After assembly with the transmission component in this way, the transmission component is not easy to detach. The force-bearing part is an elastic protrusion, which deforms and is then assembled into the first gap.

[0034] 11. Option 11: In this embodiment, α2 > α1 is greater than 90 degrees. During the pressing process, as the angle becomes larger and larger, it can be pressed down more and more easily, resulting in a better effort-saving effect.

[0035] 12. Option Twelve: Since α1 is an acute angle, i.e., when it is less than 90°, the pressing process becomes easier and easier as the angle of α1 increases. However, the pressing force will be relatively heavy in the first half of the stroke until α1 crosses the 90° right angle inflection point. This situation will create a sense of jolt at the beginning of the operation, allowing the user to clearly perceive the switching operation (similar to the function of a ball to be in position). There is a thumping sound when pressing at the 90° inflection point. In this method, the pressing distance of the operating component is shorter than that of the first embodiment, and the part of the operating component protruding from the outer surface of the main body is not very large, making it more aesthetically pleasing.

[0056] Example 1:

[0057] refer to Figures 1-10 A switching device, in this embodiment, includes a body 1, a switching component 2, an operating component 3, a transmission component 4, and a reset component 5.

[0058] refer to Figures 1-5 The main body 1 is provided with a first water outlet 11, a second water outlet 12, a receiving cavity 13, a guide hole 14, and a water passage cavity 15; in this embodiment, as shown... Figures 2 to 5 As shown, the first water outlet 11 and the second water outlet 12 have the same water outlet direction, and the water outlet direction of the first water outlet 11 and the second water outlet 12 in the figure is taken as the left direction in the first direction. The first water outlet 11 outputs aerated water, and the second water outlet 12 outputs shower water. The second water outlet 12 is arranged around the first water outlet 11. The two water outlets allow users to choose according to their needs. The guide hole 14 extends along the first direction and its two ends are connected to the water passage cavity 15 and the receiving cavity 13 respectively. The receiving cavity 13 has an opening along a second direction perpendicular to the first direction, as shown in the figure. The opening is along the second direction and faces upward.

[0059] The water passage 15 is provided with an inlet 151 and a first branch inlet 152 and a second branch inlet 153 connected to the inlet 151. The inlet 151 is connected to an external water pipe. The planes on which the first branch inlet 152 and the second branch inlet 153 are located are both perpendicular to the first direction, and the first branch inlet 152 is farther away from the guide hole 14 than the second branch inlet 153. The first branch inlet 152 is connected to the first outlet 11, and the second branch inlet 153 is connected to the second outlet 12. The connection between the inlet 151 and the external water pipe, the connection between the first branch inlet 152 and the first outlet 11, and the connection between the second branch inlet 153 and the second outlet 12 are conventional water circuit designs and will not be elaborated further.

[0060] For details, please refer to Figure 10 The main body 1 includes a water outlet 18 and a spindle 17; a guide hole 14 and a receiving cavity 13 are provided on the spindle 17. The spindle 17 and the operating member 3 are rotatably connected around a first axis. The transmission member 4 is rotatably connected to the spindle 17 around a second axis. The water outlet 18 and the spindle 17 are detachably connected and enclosed to form a water passage cavity 15. The spindle 17 is provided with a water passage groove that opens along a first direction and communicates with the guide hole 14. The water inlet 151 and the second water outlet 153 are provided in the water passage groove of the spindle 17. The first water outlet 152 is provided on the water outlet 18. The water outlet 18 and the spindle 17 are detachably connected by a sealed plug-in fit to enclose the water passage groove to form the water passage cavity 15. The first water outlet 11 and the second water outlet 12 are provided on the water outlet 18.

[0061] refer to Figures 4-6 The switching member 2 is adapted to slide relative to the body 1 along a first direction to change the state of the body 1. Specifically, in this embodiment, the switching member 2 is adapted to slide along the first direction to block the first water outlet 152 or the second water outlet 153. The switching member 2 is provided with a switching part 21 and a pushing part 22. The switching part 21 includes a guiding part 212 and a blocking part 213. The blocking part 213 is adapted to block the first water outlet 152 or the second water outlet 153. The guiding part 212 and the guiding hole 14 guide and cooperate along the first direction, so that the switching member 2 can only slide along the first direction.

[0062] Specifically, the switching component 2 includes a rod body, a first sealing element, and a second sealing element. One end of the rod body forms a push-off portion 22, which is approximately spherical, and the size of the portion of the rod body connected to the push-off portion 22 is smaller than the size of the push-off portion 22. The portion of the rod body that passes through the guide hole 14 forms a guide portion 212, and the outer contour of the guide portion 212 matches the contour of the guide hole 14. The first sealing element is sleeved on the rod body and located inside the water passage cavity 15. The first sealing element forms a sealing portion 213, and the size of the first sealing element is larger than that of the first water outlet 152 and the second water outlet 153. When the first sealing element is attached to the end face where the first water outlet 152 or the second water outlet 153 is located, a seal is achieved. The second sealing element is also sleeved on the rod body and located between the water passage cavity 15 and the guide hole 14 to prevent water from the water passage cavity 15 from flowing out of the guide hole 14.

[0063] refer to Figure 2 , Figure 3 , Figure 7 and Figure 8 The operating component 3 is rotatably connected to the body 1 about a first axis perpendicular to both the first and second directions. The first axis is located at the midpoint of the operating component 3 along the first direction. Specifically, the operating component 3 is connected to the body 1 by a pin, the central axis of which is the first axis. The operating component 3 has a first abutment surface 31 and a second abutment surface 32 that are inclined relative to the second direction and face each other. A first gap 33 is formed between the first abutment surface 31 and the second abutment surface 32. The first gap 33 can be a hole with an opening in its extending direction, such as... Figure 8 This method facilitates assembly with transmission component 4, or uses a hole-like structure without an opening in its extending direction, such as... Figure 7 After being assembled with the transmission component 4, this method ensures that the transmission component 4 is not easily detached. The body 1 is provided with two limiting surfaces 16 distributed on both sides of the first axis. When the operating component 3 rotates, the end of the operating component 3 is adapted to abut against the limiting surface 16 to prevent the operating component 3 from rotating further. The first abutting surface 31, the second abutting surface 32, and the first gap 33 are two sets, which are arranged parallel to each other along the extension direction of the first axis.

[0064] refer to Figure 9 , Figure 10The transmission component 4 is rotatably connected to the body 1 around a second axis parallel to the first axis and is used to drive the switching component 2 to slide. Specifically, the transmission component 4 can be connected to the body 1 by a pin. The connection point is located in the accommodating cavity 13. The other end of the transmission component 4 extends out of the accommodating cavity 13 and forms a force-bearing part 41. There are two force-bearing parts 41, which are respectively placed in the two first gaps 33. The force-bearing parts 41 extend in a direction parallel to the second axis and are elastic protrusions. The elastic protrusions have a certain degree of flexibility, are not easy to jam, and can easily slide in the first gaps 33. When the operating component 3 rotates around the first axis, the first abutting surface 31, the second abutting surface 32 and the first gap 33 also rotate around the first axis and their positions change. Therefore, the force-bearing part 41 will be pushed by the first abutting surface 31 or the second abutting surface 32 and thus slide in the first gap 33. While the force-bearing part 41 slides, it rotates around the second axis, thereby causing the entire transmission component 4 to rotate around the second axis.

[0065] The transmission component 4 is provided with a second gap 43 and a slide groove 42 that are inclined relative to the first direction and pass through the transmission component 4. The slide groove 42 is connected to the second gap 43. The second gap 43 is used to accommodate the pushing part 22, and the switching part 21 passes through the slide groove 42. When the transmission component 4 rotates, the switching part 21 will not rotate because it is guided and engaged with the guide hole 14 in the first direction. Therefore, when the transmission component 4 rotates, the position of the pushing part 22 in the second gap 43 changes, and the position of the switching part 21 in the slide groove 42 changes. This allows the transmission component 4 to rotate while the pushing part 22 slides only in the first direction when it is pushed by one of the two side walls of the second gap 43. This allows the switching part 2 to slide in the first direction.

[0066] refer to Figure 2 , Figure 3 In the second direction, the connection point between the transmission component 4 and the switching component 2 is located between the force-bearing part 41 and the second axis, thereby forming a force-saving lever structure, which is more convenient for users to use. That is, in the second direction, the pushing part 22 is located between the force-bearing part 41 and the second axis. The first gap 33 is located between the first axis and the second axis, thereby reducing space occupation, reducing installation difficulty and the length of the body 1, and ensuring that the three of them can form an angle.

[0067] refer to Figure 4 , Figure 5 The reset member 5 acts along the first direction on the cavity wall of the water passage 15 and the switching member 2, and is configured to drive the switching member 2 to block one of the first water outlet 152 and the second water outlet 153 when the water passage 15 is not flowing. When the reset member 5 resets, it drives the switching member 2 to slide. When the switching member 2 slides, it drives the transmission member 4 to rotate. The rotation of the transmission member 4 causes the operating member 3 to rotate, thereby also realizing the reset of the operating member 3. In this embodiment, the reset member 5 is a spring.

[0068] During installation, insert the pushing part 22 of the switching component 2 into the water groove of the spindle 17 until it passes through the guide hole 14 and extends into the receiving cavity 13. Then, fit the reset component 5 onto the switching component 2, and then seal the water outlet component 18 into the spindle 17 to complete the assembly of the water outlet part. Next, align the second gap 43 and the sliding groove 42 of the transmission component 4 with the switching part 21 and the pushing part 22 respectively, so that the switching part 21 is partially placed in the sliding groove 42 and the pushing part 22 is placed in the second gap 43. Then, rotate the transmission component 4 to connect with the spindle 17. Finally, rotate the operating component 3 to connect with the spindle 17 and place the force-bearing part 41 in the first gap 33 to complete the installation. The installation of the rotating connection can be achieved by deformation and snapping it in, thus achieving a rotating connection while preventing it from easily detaching after assembly.

[0069] refer to Figure 2 , Figure 3 In this embodiment, the first state is when the switching component 2 blocks the second water outlet 153, and the second state is when the switching component 2 blocks the first water outlet 152. In the first state, the angle between the first gap 33 and the second gap 43 is α1 (with the force-bearing part 41 as the connection point between the first gap 33 and the second gap 43). The angle between the line connecting the highest point of the rightmost end of the operating component 3 along the first direction and the first axis and the horizontal line parallel to the first direction is β1 (in this embodiment, the central axis of the body 1). The height between the highest point of the rightmost end of the operating component 3 along the first direction and the surface of the body 1 along the second direction is h1. The extension of the second gap 43... The angle between the direction and the horizontal line parallel to the first direction is γ1, and the minimum distance from the end face of the rod perpendicular to the first direction to the guide hole 14 is d1. In the second state, the angle between the line connecting the first gap 33 and the second gap 43 is α2, the angle between the line connecting the highest point of the rightmost end of the operating member 3 along the first direction and the first axis and the horizontal line parallel to the first direction is β2, the angle between the extension direction of the second gap 43 and the horizontal line parallel to the first direction is γ2, the minimum distance from the end face of the rod perpendicular to the first direction to the guide hole 14 is d2, and the highest point of the rightmost end of the operating member 3 along the first direction is flush with the surface of the body 1. Wherein, α1 is 83.87°-111.13°, β1 is 17.26°-19.65°, α2 is 107.22°-133.22°, and β2 is 8.92°-9.05°.

[0070] In this embodiment, α2 > α1, which is greater than 90 degrees. During the pressing process, as this angle increases, it becomes easier to press down, resulting in better effort-saving effect. In the first state, α1 is 111.13°, β1 is 19.65°, γ1 is 106.86°, h1 is 4.12, and d1 is 3.02. In the second state, α2 is 133.22°, β2 is 9.05°, γ1 is 118.36°, and d1 is 0.82. Therefore, during the transition from the first state to the second state, the operating component 3 rotates clockwise by 10.6 degrees, the transmission component 4 rotates counterclockwise by 11.5°, and the switching component 2 slides by 2.2 degrees. Similarly, since the first axis is located at the center of the operating component 3 in the first direction, it is an equal-arm lever, and the left and right ends of the operating component 3 rotate at the same angle.

[0071] refer to Figure 4 , Figure 5 In the first state, the switching element 2 is stopped by the rightward elastic force of the reset element 5 and the rightward water force. In the second state, the switching element 2 is stopped by the rightward elastic force of the reset element 5 and the leftward water force, with the water force being greater than the elastic force. When the water passage 15 is not filled with water, the switching element 2 is only subjected to the rightward elastic force, thus stopping in the first state. From the state where the water passage 15 is not filled with water to the state where the water passage 15 is filled with water, the switching element 2 is still stopped in the first state by the rightward elastic force of the reset element 5 and the rightward water force. Therefore, regardless of the state, as long as no force is applied to the operating element 3, the state will not switch, ensuring stability during use. Furthermore, when the water is turned off, the state is unique, making it convenient for users to use the frequently used mode next time, reducing switching operations. Since the second water outlet 153 is always blocked initially, the angle between the line connecting the first gap 33 and the second gap 43 is an obtuse angle, and this angle gradually increases during the switching process. Therefore, it becomes increasingly easier to press the operating component 3, making it more convenient to use. When the water passage 15 is not filled, the switching component 2 automatically resets to block the second water outlet 153, and the user does not need to press it again. Even if more force is required during the process of switching from blocking the first water outlet 152 to blocking the second water outlet 153, this force is provided by the reset component 5, so the user does not need to operate it, or the operation is more effortless due to the function of the reset component 5.

[0072] This method changes the sliding direction of the switching component 2 through the transmission component 4, thereby making the radial dimension of the body 1 smaller. When applied to a shower head, it can make the radial dimension of the handle smaller and easier to grip.

[0073] Example 2:

[0074] refer to Figure 11 , Figure 12In the first state, α1 is 83.87°, β1 is 17.26°, γ1 is 93.50°, h1 is 3.2, and d1 is 3.06. In the second state, α2 is 107.22°, β2 is 8.92°, γ1 is 108.5°, and d1 is 0.91. Therefore, during the transition from the first state to the second state, the operating component 3 rotates clockwise by 8.34°, the transmission component 4 rotates counterclockwise by 15°, and the switching shaft slides by 2.15. In this mode, since α1 is an acute angle, i.e., it is less than 90°, the pressing process at this time... As the angle of α1 increases, it becomes easier to press down. However, the pressing force is relatively heavy in the first half of the stroke until α1 crosses the 90° right angle inflection point. This situation will create a sense of jerkiness at the beginning of the operation, allowing the user to clearly perceive the switching operation (similar to the function of a ball to be in position). There is a thumping sound when pressing at the 90° inflection point. In this method, the pressing distance of the operating part 3 is shorter than that of the first embodiment. The part of the operating part 3 that protrudes from the outer surface of the body 1 is not very large, which is more aesthetically pleasing. However, the applied force is correspondingly greater than that of the first embodiment.

[0075] According to Embodiments 1 and 2, the closer the first gap 33 is to the right end, i.e., the farther it is from the first axis, the larger the lever arm and the less effort is required. Furthermore, according to the lever principle, this is also related to the tilt angle of the first gap 33, the distance between the connection point of the transmission member 4 and the switching member 2 and the second axis in the second direction, and the position of the force-receiving part 41 relative to the first gap 33. Under the same work done (i.e., the distance the switching member 2 moves), more effort is required to save pressing distance. Conversely, to save effort, the pressing distance needs to be appropriately increased.

[0076] Of course, in other embodiments, in order to make the sliding distance of the switching member 2 greater, the force-bearing part 41, the second axis and the pushing part 22 can be distributed from top to bottom in sequence, and the distance between the force-bearing part 41 and the second axis is less than the distance between the pushing part 22 and the second axis.

Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
