Description

“ENHANCED NEXT-GENERATION ELECTRO MECHANICAL COUPLING SYSTEM FOR ENDOSCOPIC INSTRUMENTS”FIELD OF INVENTION

[0001] The present application is based on and claims priority from an Indian Provisional Application Number 202441012232 filed on 21stFebruary 2024, the disclosure of which is hereby incorporated by reference herein. The proposed embodiments relate to medical devices. More particularly relates to enhanced next-generation electro-mechanical coupling system for endoscopic instruments.BACKGROUND

[0002] Endoscopy is a medical procedure that involves the insertion of a flexible or rigid tube, known as an endoscope, into the body to visualize internal organs and tissues. The engineering field of endoscopy encompasses the design and development of various components, connectors, and mechanisms that ensure the secure and efficient operation of endoscopes. These components maintain the electrical connections and manage the insertion forces on the connectors, which, in turn, enhance the overall functionality and durability of endoscope systems.

[0003] A typical video endoscope used in medical procedures includes a video processor, a light source, and a scope part designed for viewing internal body structures. The scope part connects to the video processor via a scope connector that facilitates electrical connection and data transfer. The electrical contacts in the scope connectors are generally prepared using over-molding techniques such as injection molding or insert molding.

[0004] In conventional electrical systems, pogo connectors or pogo contacts are commonly used for the electrical connections and data transfer. However, pogo connectors necessitate a constant holding force and lack a locking mechanism, which can result in potential issues with the reliability of the electrical connection between the scope connector and the video processor. This lack of secure locking mechanisms can lead to an intermittent connection, which compromise the quality and reliability of an endoscopic procedure.

[0005] Furthermore, conventional connectors often incorporate additional components such as permanent magnets, electromagnets, and solenoids to create an external force that maintains the pogo connections in place. These components can introduce undesirable jerking motions during engagement and disengagement operations, which can be detrimental to the usability of the device and delicate nature of endoscopic equipment. Additionally, the inclusion of these extra components increases the size of the connectors due to the need for additional space and separate electrical circuitry. This increase in size can make endoscopes more heavier and complex in design which further increases the cost.

[0006] Thus, it is required to address the above-mentioned disadvantages or other shortcomings or at least provide a useful alternative.OBJECT OF INVENTION

[0007] The principal object of the embodiments herein is to provide an enhanced next-generation electro-mechanical coupling system for endoscopic instruments. The electro-mechanical coupling system ensures secure and efficient electrical connections as well as the management of insertion forces on connectors, thereby enhancing the overall functionality and durability of endoscope systems.

[0008] Another object of the invention herein is to encompass the design and development of components, connectors, and mechanisms used in endoscopes to ensure secure and efficient electrical connection, as well as the management of insertion forces on pogo connectors, thereby enhancing the overall functionality and durability of endoscope systems.

[0009] Yet another object of the invention herein is to provide a mechanical pogo connector that does not rely on magnetism or electromagnetism for locking and keeping the connection engaged throughout. This unique feature is achieved through the external spring -based mechanism provided for pogo connectors. This mechanism, when combined with the locking mechanism, enables the scope connector to enter and automatically lock in place once it reaches its designated position without requiring human intervention.SUMMARY

[0010] In one aspect, the objects are achieved by providing an electromechanical coupling system for endoscopic instruments. The electro-mechanical coupling system includes a first connector assembly and a second connector assembly. The first connector assembly includes a first lock member on a surface of the first connector assembly and a first electrical connector at a face of the first connector assembly. The second connector assembly is configured to connect with the first connector assembly. The second connector assembly includes a housing defining a cavity for receiving the first connector assembly, a second lock member positioned on the housing, a static structure connected at an end of the housing, and an electrical connection assembly affixed to a moving plate, positioned between the housing and the static structure. The electrical connection assembly includes a second electrical connector affixed to the face of the movable structure. The movable structure is mounted on the static structure using alignment guides. During an insertion operation, an insertion force applied to insert the first connector assembly into the housing causes the first lock member to automatically engage the second lock member and establishes an electrical connection by engaging the second electrical connector with the first electrical connector. During a removal operation, the applied insertion force is removed by pressing the first lock member by a user that automatically unlocks the second lock member and disengages the second electrical connector with the first electrical connector, stopping the electric connection.

[0011] In an embodiment, the electrical connection assembly includes a printed circuit board (PCB) connected to the second electrical connector and a mechanical energy storing element mounted on each of the alignment guides, wherein the mechanical energy storing element gets pulled in when the first connector assembly is inserted inside the cavity of the second connector assembly to connect the first connector assembly to the second connector assembly. When the insertion force is removed, the mechanical energy storing element pushes the first connector assembly outward the cavity to disconnect the first connector assembly from the second connector assembly. Further, the electrical connection assembly includes a motion limiting element mounted over the mechanical energystoring element on each of the alignment guides, wherein the motion limiting element restricts movements of the movable structure beyond a maximum insertion point indicating the user of maximum insertion.

[0012] In an embodiment, the first lock member automatically allows the first connector assembly to enter inside the cavity without the user need to lift the first connector assembly, and wherein the first lock member works in one side direction allowing the first connector assembly to go inside the cavity while restricting the first connector assembly from coming outside the cavity without intervention of the user.

[0013] In an embodiment, the mechanical energy storing element is compressed during the insertion when the insertion force is applied, allowing complete insertion of the first connector assembly into the cavity.

[0014] In an embodiment, during the insertion operation, when the movable structure moves rearward towards the static structure, the mechanical energy storing element mounted on each of the alignment guides begins to compress and the second lock member secures the movable structure in place when the first connector assembly reaches a locking position. When the movable structure reaches the maximum insertion point, the motion limiting element halts further insertion of the first connector assembly, indicating to the user that full insertion has been achieved and that the insertion force should be released.

[0015] In an embodiment, upon removal of the insertion force, the mechanical energy storing element mounted on each of the alignment guides exerts an outward force on the first connector assembly. The first lock member and second lock member in conjunction do not permit the mechanical energy storing elements to push the first connector assembly outward, thereby maintaining continuous engaging force required for the connection.

[0016] In an embodiment, the alignment guides facilitate controlled movement of the movable structure during the engagement of the first connector assembly with the second connector assembly. In an embodiment, the static structure comprises a plurality of slots configured to accommodate a passage of thealignment guides, thereby facilitating the alignment and movement of the movable structure.

[0017] In an embodiment, the movable structure is operatively connected to the static structure in a manner that permits movement relative to the static structure. In an embodiment, a user inserts the first connector assembly into the housing, the second lock member enables the first connector assembly to be inserted without requiring human intervention. When the face of the first connector assembly comes into contact with the face of the movable structure, the insertion force evenly distributes across the entire surface of the movable structure. In an embodiment, the first electrical connector is a female connector and the second electrical connector is a male connector.

[0018] In an embodiment, the first electrical connector at a face of the first connector assembly constitutes a water-proof assembly and makes the first connector assembly a water-proof unit. The holding force required for the first electrical connector and the second electrical connector to stay connected is provided by an energy storing element in combination with a locking mechanism. In an embodiment, the first connector assembly and the second connector assembly utilize electrical connectors that are non-insertable and operate by maintaining a surface contact.

[0019] In an embodiment, the first electrical connector at a face of the first connector assembly constitutes a water-proof assembly and makes the first connector assembly a water-proof unit. In an embodiment, the holding force required for the first electrical connector and the second electrical connector to stay connected is provided by the mechanical energy storing element in combination with a locking mechanism. The first connector assembly and the second connector assembly utilize electrical connectors that are non-insertable and operate by maintaining a surface contact.

[0030] The embodiments herein and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. Also, the various embodiments described herein are not necessarily mutually exclusive, as some embodiments can be combined with one or more other embodiments to form new embodiments. The term “or” as used herein, refers to a non-exclusive or, unless otherwise indicated. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein can be practiced and to further enable those skilled in the art to practice the embodiments herein. Accordingly, the examples are not to be construed as limiting the scope of the embodiments herein.

[0031] The accompanying drawings are used to help easily understand various technical features and it is understood that the embodiments presented herein are not limited by the accompanying drawings. As such, the proposed method is construed to extend to any alterations, equivalents and substitutes in addition to those which are particularly set out in the accompanying drawings. Although the terms first, second, etc. used herein to describe various elements, theseelements are not limited by these terms. These terms are generally used to distinguish one element from another.

[0032] Embodiments disclosed herein provide an electro-mechanical coupling system for endoscopic instruments. The electro-mechanical coupling system includes a first connector assembly and a second connector assembly. The first connector assembly includes a first lock member on a surface of the first connector assembly and a first electrical connector at a face of the first connector assembly. The second connector assembly is configured to connect with the first connector assembly. The second connector assembly includes a housing defining a cavity for receiving the first connector assembly, a second lock member positioned on the housing, a static structure connected at an end of the housing, and an electrical connection assembly positioned between the housing and the static structure. The electrical connection assembly includes a second electrical connector affixed to a face of a movable structure that allows electrical contacts to protrude outward and alignment guides mounted on the movable structure. During an insertion operation, an insertion force applied to insert the first connector assembly into the housing causes the first lock member to automatically engage the second lock member and establishes an electrical connection by engaging the second electrical connector with the first electrical connector. During a removal operation, the applied insert force is removed by pressing the first lock member by a user of the electro-mechanical coupling system that automatically unlocks the second lock member and disengages the second electrical connector with the first electrical connector, stopping the electric connection.

[0033] Conventional video endoscope connectors typically employ custom mold-in connectors requiring significant investments in die manufacturing and tooling. This substantially increases manufacturing costs, leading to more expensive endoscope systems. Conventional endoscopes utilizing mold-in metal points for electrical connections face repair challenges. A fault in the electrical connector necessitates the replacement of the molded component, increasing maintenance costs. Furthermore, conventional connectors are prone to wear andtear over time due to friction between contact points, potentially compromising their durability.

[0034] Unlike the conventional surface contact based connectors being used in endoscopes or other electro-mechanical systems, the proposed electromechanical coupling system uses point contact based connectors like pogo connectors. The proposed point contact based electro-mechanical coupling system’s engaging mechanism is entirely mechanical, eliminating the need for magnets or electromagnets or solenoids. This innovative approach utilizes an external spring-based mechanism for the connector assembly, enabling the first connector assembly to automatically lock in place once it reaches its designated position. This eliminates the need for the magnets or solenoids The mechanical nature of the electro-mechanical coupling system also means that it is not dependent on electricity for its locking and engagement. Further by eliminating the need for the magnet or solenoid, reducing the space requirement along with cost.

[0035] Additionally, the electro-mechanical coupling system utilizes readily available off-the-shelf connector assemblies, addressing the challenges associated with traditional connectors. This approach reduces manufacturing expenses, resulting in a more cost-effective and accessible end product, and lowering the overall cost of endoscopy procedures. The connector assemblies establish point contacts when connected, as opposed to surface contacts, leading to decreased contact resistance, reduced voltage drops, and reduced heat generation. By eliminating mold-in connectors, repair costs are minimized. In the event of connector assemblies wear or damage beyond its operational lifespan, the first and second connector assemblies require replacement. This modularity simplifies maintenance and also ensures that the endoscopic system remains operational with minimal downtime, thereby improving the efficiency of medical procedures.

[0036] Furthermore, the design of the electro-mechanical coupling system enhances user experience and operational efficiency. The automatic locking mechanism ensures that the connectors are securely fastened without the need for manual intervention, thereby eliminating the risk of the endoscope connector not being properly secured, which could result in adverse incidents affecting the patientwhen using the product. The alignment guides on the movable structure facilitate precise alignment of the electrical contacts of the point based connectors, ensuring reliable electrical connections every time.

[0037] Referring now to the drawings and more particularly to FIGS. 1 through 7D, where similar reference characters denote corresponding features throughout the figure, these are shown preferred embodiments.

[0038] FIG 1 illustrates an exploded view of an electro-mechanical coupling system (100) for endoscopic instruments according to an embodiment as disclosed herein. The electro-mechanical coupling system (100) includes a first connector assembly (1) and a second connector assembly (2). The first connector assembly (1) includes a first lock member (3) on a surface of the first connector assembly (1) and a first electrical connector (4) at a face of the first connector assembly (1). The second connector assembly (2) is configured to connect with the first connector assembly (1). The second connector assembly (2) includes a housing (5) defining a cavity for receiving the first connector assembly (1), a second lock member (6) positioned on the housing (5), a static structure (7) connected at an end of the housing (5), and an electrical connection assembly (8) positioned between the housing (5) and the static structure (7). The electrical connection assembly (8) comprises a second electrical connector (9) affixed to a face of a movable structure (10) that allows electrical contacts to protrude outward and alignment guides (11) mounted on the movable structure (10). During the insertion operation, the insertion force applied to insert the first connector assembly (1) into the housing (5) causes the first lock member (3) to automatically engage the second lock member (6) and establishes the electrical connection by engaging the second electrical connector (9) with the first electrical connector (4). During a removal operation, the applied insert force is removed by pressing the second lock member (6) by the user of the electromechanical coupling system (100) disengages the second electrical connector (9) with the first electrical connector (4), stopping the electric connection.

[0039] In an embodiment, the second lock member (6) automatically allows the first connector assembly (1) to enter inside the cavity without the user needing to lift the second lock member(6), and wherein the second lock member (3) worksin one side direction allowing the first connector assembly (1) to go inside the cavity while restricting the first connector assembly (1) from coming outside the cavity in conjunction with first lock member(3) without intervention of the user. The electrically conductive side of the second connector assembly (2) aligns perfectly with the first electrical connector (4) of the first connector assembly (1). The first lock member (3) on the surface of the first connector assembly (1) is of a ridgeshaped feature that facilitates locking-engagement with the second connector assembly (2).

[0040] In another embodiment, the cavity of the second connector assembly (2) mimics the shape of the first connector assembly (1). The cavity serves as the insertion point for the first connector assembly (1), providing guidance during the insertion process. The front side of the second connector assembly (2) is equipped with the second lock member (6). This design ensures that the first connector assembly (1) is guided accurately into place, minimizing the risk of misalignment and potential damage to the electrical connectors. Additionally, the precise alignment facilitated by the cavity shape contributes to the reliability and durability of the electro-mechanical coupling system (100).

[0041] In yet another embodiment, the static structure (7) is directly attached to the second connector assembly (2) using fasteners. The static structure (7) features an aperture design that permits the alignment guides (11) to pass through and assist in the reciprocation of the movable structure (10). The movable structure (10) is mounted on the static structure (7) in a cantilever fashion. This configuration allows the movable structure (10) to flex and move in response to the insertion and removal forces applied to the first connector assembly (1). The cantilever mounting provides a balance between flexibility and stability, ensuring that the electrical connection is maintained securely while allowing for easy disconnection when necessary. This design is advantageous in endoscopic instruments where space is limited and precise movements are required.

[0042] FIGS 2A-2C illustrate a locking operation of the electro-mechanical coupling system (100) for endoscopic instruments according to the embodiment as disclosed herein. The second lock member (6), which is a front-positioned lever-lock, acts as a stopper, not allowing the first connector assembly (1) to come outside without manual interruption and secures the first connector assembly (1) at its position. The second lock member (6) also facilitates automatic locking in combination with the first lock member (3). The static structure (7) secures the movable structure (10) in a cantilever position. The static structure (7) design includes four apertures for the alignment guides (11), ensuring stability and proper positioning. Additionally, the static structure (7) is fastened to the second connector assembly (2), thus making it a one single receiving unit.

[0043] In an embodiment, when the face of the first connector assembly (1) comes into contact with the face of the movable structure (10), the insertion force evenly distributes across the entire surface of the movable structure (10). This even distribution of force minimizes the risk of damage to the components and ensures a secure and reliable connection. The design of the movable structure (10) is such that it can absorb and distribute the insertion force effectively, thereby enhancing the durability and longevity of the coupling system.

[0044] Furthermore, the alignment guides (11) maintain the proper positioning of the first connector assembly (1) relative to the second connector assembly (2). These guides ensure that the connectors align correctly, reducing the likelihood of misalignment and potential damage. The apertures in the static structure (7) are precisely engineered to accommodate the alignment guides (11), providing a snug fit that enhances the overall stability of the system. The combination of the lever-lock mechanism, the cantilever positioning, and the alignment guides results in a robust and efficient coupling system suitable for the point based electrical connectors like pogo connectors for the demanding environment of endoscopic procedures.

[0045] FIG. 3 illustrates a perspective view of the first connector assembly (1) of the electro-mechanical coupling system (100) according to an embodiment as disclosed herein. The first electrical connector is a female type pogo connector and is fastened in the first electrical connection assembly (1). The first electrical connectors (4) are secured within the first electrical connection assembly (1) using fasteners or other fastening techniques such as, but not limited to, snap fit with awater-tight sealing from the inside of the connector (not shown). The first electrical connection assembly (1) is closed along with the electrical connections of the first electrical connectors (4) using the fasteners. The electrically conductive side of the first electrical connectors (4) aligns with the second electrical connectors (9) of the second electrical connection assembly (2), known as the front side of the second electrical connection assembly (2).

[0046] In one embodiment, the first electrical connector (4) is a female connector, and the second electrical connector (9) is a male connector. Examples of suitable first electrical connectors (4) include female pogo connectors, and examples of suitable second electrical connectors (9) include male pogo connectors. The alignment between the first and second electrical connectors ensures a reliable and efficient electrical connection. The water-tight sealing feature of the first connector assembly (1) enhances the durability and reliability of the system, making it suitable for use in various environmental conditions.

[0047] In an embodiment, the first electrical connector (4) at a face of the first connector assembly (1) constitutes a water-proof assembly and makes the first connector assembly (1) a water-proof unit. The holding force required for the first electrical connector (1) and the second electrical connector (2) to stay connected is provided by an energy storing element in combination with a locking mechanism. In an embodiment, the first connector assembly (1) and the second connector assembly (2) utilize the electrical connectors that are non-insertable and operate by maintaining a surface contact.

[0048] FIGS. 4A-4B illustrate a perspective view of the second connector assembly (2) of the electro-mechanical coupling system (100) according to an embodiment as disclosed herein. The static structure (7) of the second connector assembly (2) comprises a plurality of slots configured to accommodate the passage of the alignment guides (11), thereby facilitating the alignment and movement of the movable structure (10). The alignment guides (11) facilitate controlled movement of the movable structure (10) during the engagement of the first connector assembly (1) with the second connector assembly (2). This controlledmovement is for ensuring a precise and secure connection between the first and second electrical connectors.

[0049] In an embodiment, the movable structure (10) is operatively connected to the static structure (7) in a manner that permits movement relative to the static structure (7). The user inserts the first connector assembly (1) into the housing (5), and the second lock member (6) enables the first connector assembly (1) to be inserted without requiring human intervention. This feature enhances the ease of use and efficiency of the coupling system. In an embodiment, the alignment guides (11) can be Directional Cylindrical Guides (DCG), which are mounted on the rear side of the movable structure. The alignment guides (11) restrict the movement of the movable structure (10) to a single axis during the connection process. This restriction ensures that the point based connectors align correctly, preventing any potential damage or misalignment.

[0050] In an embodiment, the alignment guides (11) incorporate a design element that secures the movable structure (10) to the static structure (7). The alignment guides (11) positioned at the rear of the movable structure (10) are guided by guiding apertures in the static structure (7), ensuring controlled movement. The entire sliding mechanism is securely attached to the static structure (7), which is in turn affixed to the second electrical connection assembly (2).

[0051] In an embodiment, the movable structure (10) is capable of reciprocating forwards and backwards and supports the electrical connection assembly (8) via the fasteners. The movable structure (10) is cantilever-mounted on the static structure (7). The side from which the second electrical connectors (9) extend outward is referred to as the "front face." The second electrical connector (9) is a male-type-pogo connector and is fastened in the movable structure (10), ensuring a robust and reliable connection with the first electrical connector (4).

[0052] FIG 5 illustrates another perspective view of the second connector assembly (2) of the electro-mechanical coupling system (100) according to an embodiment as disclosed herein. The electrical connection assembly (8) of the second connector assembly (2) includes a PCB (12) connected to the second electrical connector (9) and a mechanical energy storing element (13) mounted oneach of the alignment guides (11). The mechanical energy storing element (13) gets pulled in when the first connector assembly (1) is inserted inside the cavity of the second connector assembly (2) to connect the first connector assembly (1) to the second connector assembly (2). When the insertion force is removed by pressing down the second lock member (6), the mechanical energy storing element (13) pushes the first connector assembly (1) outward from the cavity to disconnect the first connector assembly (1) from the second connector assembly (2).

[0053] Further, the electrical connection assembly (8) includes a motion limiting element (14) mounted over the mechanical energy storing element (13) on each of the alignment guides (11). The motion limiting element (14) restricts movements of the movable structure (10) beyond a maximum insertion point. The motion limiting elements (14) are allowed to move freely between the movable structure (10) and the static structure (7). The purpose of the motion limiting elements (14) is to prevent the movable structure (10) from moving backward beyond a specific point, thereby ensuring that the mechanical energy storing elements (13) do not fully compress, extending their lifespan.

[0054] In addition to these components, the second connector assembly (2) is designed to facilitate ease of maintenance and replacement. The alignment guides (11) are constructed to ensure precise alignment during the coupling and decoupling processes, minimizing wear and tear on the mechanical energy storing elements (13) and the motion limiting elements (14). This precision alignment also helps in maintaining the integrity of the electrical connections between the PCB (12) and the second electrical connector (9). The design considerations taken in the second connector assembly (2) highlight the importance of durability and reliability in the overall functionality of the coupling system.

[0055] Moreover, the integration of the mechanical energy storing elements (13) and motion limiting elements (14) within the alignment guides (11) showcases an innovative approach to managing mechanical stresses within the connector assembly. By controlling the movement and compression of these elements, the system can better withstand repeated cycles of connection and disconnection. This thoughtful engineering not only enhances the operational lifespan of the connectorassembly but also reduces frequent maintenance, thereby providing a more cost- effective and reliable solution for users.

[0056] FIGS 6A-6D illustrate the exploded views of the second connector assembly of the electro-mechanical coupling system according to an embodiment as disclosed herein. The mechanical energy storing element (13) is compressed during insertion when the insertion force is applied, allowing complete insertion of the first connector assembly (1) into the cavity. During the insertion operation, when the movable structure (10) moves rearward towards the static structure (7), the mechanical energy storing element (13) mounted on the alignment guides (11) begins to compress, and the second lock member (6) secures the movable structure (10) in place when the first connector assembly (1) reaches a locking position. When the movable structure (10) reaches the maximum insertion point, the motion limiting element (14) halts further insertion of the first connector assembly (1), indicating to the user that full insertion has been achieved and that the insertion force to be released.

[0057] In an embodiment, upon removal of the insertion force, the mechanical energy storing element (13) mounted on the alignment guides (11) exerts an outward force on the first connector assembly (1). However, the second lock member (6) in conjunction with first lock member (3) ensures that the first connector assembly (1) remains securely engaged within the cavity, maintaining the necessary connection. In another embodiment, the first lock member (3) and the second lock member (6) work in conjunction to prevent the mechanical energy storing elements (13) from pushing the first connector assembly (1) outward, thereby maintaining the continuous engaging force required for the connection. This locking mechanism in conjunction with the energy storing element’s outward force ensures that the force required for point based connectors like pogo connectors is provided throughout with any magnetism or electro-magnetism and connection remains stable and secure.

[0058] In an embodiment, the mechanical energy storing element (13) can be a set of compression springs positioned between the movable structure (10) and the static structure (7). The mechanical energy storing elements (13) allow themovable structure (10) to reciprocate back and forth when the insertion force is applied and removed, respectively. This reciprocating motion ensures that the connector assemblies can be easily engaged and disengaged without causing wear and tear on the components. In an alternative embodiment, magnetism and the solenoid plunger represent alternatives to the mechanical energy storing element (13). However, using magnets introduces challenges. Firstly, the magnets may generate magnetic radiation and require additional space. Moreover, the engagement and disengagement with magnets can be less smooth, resulting in a jerky motion.

[0059] The choice of mechanical energy storing elements, such as compression springs, magnets, or solenoid plungers, depends on the specific requirements and constraints of the application. Compression springs offer a simple and reliable solution, providing smooth and motion during insertion and removal. Magnets offer the advantage of contactless operation but come with the drawbacks of potential magnetic interference and less smooth motion. Solenoid plungers provide precise control over the engagement and disengagement process but require an electrical power source and a more complex control system.

[0060] FIGS 7A-7D illustrate the front and rear sides of the second connector assembly of the electro-mechanical coupling system according to an embodiment as disclosed herein. In an embodiment, the alignment guides (11) are attached to the rear side of the movable structure (10) to guide its reciprocating motion. The alignment guides (11) have one more function, which is to make sure that the mechanical energy storing element (13) does not get buckled during the functioning.

[0061] The alignment guides (11) ensure the stability and precision of the movable structure (10). By providing a controlled path for the reciprocating motion, the alignment guides (11) help in minimizing any lateral displacement or misalignment that could otherwise lead to operational inefficiencies or mechanical failures especially in case of point based electrical contacts. This is important in high-precision applications where even minor deviations can result in significant performance degradation. The alignment guides (11) are typically made fromdurable materials that can withstand repeated stress and maintain their structural integrity over extended periods of use.

[0062] Additionally, the mechanical energy storing element (13) is designed to store and release energy in a controlled manner, contributing to the overall efficiency of the electro-mechanical coupling system. The alignment guides (11) ensure that the mechanical energy storing element (13) remains in its optimal position, preventing any buckling or deformation that could compromise its functionality. This is achieved by providing lateral support and maintaining the alignment of the mechanical energy storing element (13) throughout its operational cycle. The integration of the alignment guides (11) with the movable structure (10) and the mechanical energy storing element (13) exemplifies a well-thought-out design that enhances the reliability and performance of the electro -mechanical coupling system.
