Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical switches with convertible rocker mechanisms face issues such as incorrect coupling, breakage, and difficulty in transitioning between push-button and two stable-position functions due to force-dependent coupling methods and susceptibility to disengagement.
Innovation Solution
A slidingly assembled activation element with a guided geometry and spring mechanism that allows for easy conversion between switch positions without requiring forceful coupling, using a cylindrical activation element and base shaft guidance to ensure secure and robust operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pressure coupling method is used to connect the force transmission element to the rocker, then the conversion between push-button and two stable-position functions is enabled, but the coupling is susceptible to breakage and incorrect coupling when force is applied
Solution Approach 1:
The force transmission element is divided into multiple independent coupling points (first coupling point and second coupling point) distributed around its circumference. This segmentation allows the element to connect to different positions on the rocker head, enabling functional conversion while distributing mechanical stress across multiple locations, thereby reducing the risk of breakage at any single coupling point.
Solution Approach 2:
The force transmission element is designed with universal coupling capability to work with both push-button mode and two stable-position mode through different coupling point selections. The same physical component serves multiple functions by varying its connection configuration, eliminating the need for different specialized components for each mode.
2Adaptability or versatility
If tool-based uncoupling method is used to disconnect the force transmission element, then the switch can be converted back to two stable-position function, but the uncoupling manoeuvre is difficult and breakage may occur
Solution Approach 1:
The switch mechanism enables self-service conversion between modes through user-operable components. The activation element with its projection can be manually manipulated to engage or disengage coupling points without requiring external tools. The user can directly control the coupling state by operating the activation element, making the conversion process simple and tool-free.
3Stability of the object's composition
If the force transmission element remains adhered to the rocker in inactive position, then it is prevented from being misplaced, but a pivot point susceptible to breakage or failure is created
Solution Approach 1:
The force transmission element transitions from a static adhered state to a dynamic removable state. In the inactive position, the element can be freely positioned or removed without being permanently fixed to the rocker. This dynamic configuration allows the element to be repositioned or detached as needed, eliminating the creation of permanent pivot points that would be susceptible to breakage while maintaining positional stability during active use through controlled coupling.

AI summary
Convertible electrical switch with an actuating rocker (1) assembled on a base (2) such that it can swivel between two stable switch connection and disconnection positions, and with an activation element (3) connectable to the actuating rocker (1) pushing the actuating rocker (1) into a single stable position when the activation element (3) and the rocker (1) are connected in an activation position, wherein the activation element is arranged such that it is slidingly assembled in a guided manner through a window (1.1) of the rocker (1) with a geometry in correspondence with the external geometry of the activation element (3) such that in the inactive position the activation element (3) goes through the window without pushing the rocker (1), whereas in the activation position the activation element (3) is configured to push the rocker (1) after establishing a rotation of said activation element (3).
