Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surge protection devices (SPDs) have complex structures and require numerous components, making them costly and difficult to manufacture, while they often fail to effectively feed back tripping signals to the control end, compromising safety and reliability.
Innovation Solution
A signal feedback apparatus using a telesignaling linkage member with a driving and driven oblique surface mechanism, a sliding plate, and a microswitch, which allows for stable sliding and reduces the number of components needed, enabling effective signal feedback and secure connections, thereby enhancing safety and manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple microswitches are installed for each level in the existing SPD telesignaling device, then the tripping signal feedback is achieved, but the device structure becomes complicated and requires greater number of components
Solution Approach 1:
The patent combines multiple microswitches into a single microswitch by using a common sliding plate that is pushed by any of the functional rotating members. When any functional rotating member trips, it pushes the sliding plate which then actuates the single microswitch to generate the telesignaling signal, thereby reducing component count while maintaining reliability
Solution Approach 2:
The sliding plate serves as a universal component that can be actuated by any of the multiple functional rotating members (first, second, third, etc.). This single sliding plate replaces multiple level-specific microswitches, allowing one component to perform the function of multiple switches across different protection levels
2Reliability
If multiple microswitches and corresponding circuits are used for each level, then the tripping monitoring is achieved, but the manufacturing process becomes complicated
Solution Approach 1:
The patent merges multiple independent microswitch circuits into a single microswitch circuit that is shared by all protection levels. The common sliding plate mechanism allows any functional rotating member to trigger the same microswitch, significantly simplifying the manufacturing process by reducing the number of components that need to be assembled and tested
3Device complexity
If a common sliding plate with oblique surfaces is used to link multiple functional rotating members, then the number of components is reduced, but the sliding stability must be ensured
Solution Approach 1:
The patent uses oblique (inclined) surfaces instead of flat surfaces on the sliding plate and functional rotating members. These curved/angled surfaces guide the sliding motion and provide mechanical advantage, ensuring stable and controlled movement of the sliding plate when actuated by any functional rotating member, thereby maintaining sliding stability with fewer components

AI summary
A liquid-cooled heat dissipation apparatus includes a base (10), a telesignaling linkage member (20), a sliding plate (30) and a switch module (40). The telesignaling linkage member (20) is moveably installed on the base (10). The sliding plate (30) is installed corresponding to the telesignaling linkage member (20) and generates a movement along with the telesignaling linkage member (20). The switch module (40) includes a microswitch (41) arranged corresponding to the sliding plate (30) such that the microswitch (41) is operably opened or closed based on the movement of the sliding plate (30). Accordingly, through the opening and closing of the microswitch, the telesignaling monitoring on the functional module state can be achieved.
