Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices experience fretting corrosion due to horizontal movement of connecting devices, leading to surface wear and unstable contact resistance, which affects the reliability and longevity of electronic connections.
Innovation Solution
A connecting device with a movable part and elastic parts arranged in a C-clip shape, allowing movement in one direction while restricting horizontal movement, thereby reducing wear and corrosion by maintaining stable contact through elastic forces and support structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the movable part is allowed to move in both vertical and horizontal directions to accommodate target movement, then the adaptability of the connecting device is improved, but surface wear and fretting corrosion increase due to horizontal movement
Solution Approach 1:
The movable part is segmented into distinct functional regions: a contacting part for vertical movement and an elastic part with bends that restrict horizontal movement. This segmentation allows the device to adapt to vertical target movement while preventing harmful horizontal displacement that causes wear and corrosion.
Solution Approach 2:
The elastic part with alternately arranged bends provides dynamic flexibility in the vertical direction while maintaining rigidity against horizontal movement. This dynamic structure allows controlled movement where needed while restricting movement that causes damage, resolving the contradiction between adaptability and wear prevention.
2Object-affected harmful factors
If the connecting device uses a rigid structure to prevent horizontal movement, then fretting corrosion is reduced, but the device cannot accommodate movement of the target
Solution Approach 1:
Different parts of the movable structure have different mechanical properties: the contacting part allows vertical movement to accommodate target displacement, while the elastic part with bends provides rigidity against horizontal movement. This local differentiation of mechanical properties resolves the contradiction between preventing corrosion and accommodating movement.
Solution Approach 2:
The elastic part changes its effective stiffness parameter based on direction: it is flexible in the vertical direction to accommodate target movement but rigid in the horizontal direction to prevent fretting corrosion. This directional parameter change resolves the contradiction between adaptability and corrosion resistance.
3Ease of operation
If the elastic part includes multiple alternately arranged bends to provide elastic force, then the movable part can move smoothly in one direction, but the device complexity increases
Solution Approach 1:
The elastic part combines multiple bends into a single integrated component that provides both the elastic force for smooth movement and the structural rigidity for horizontal restriction. This merging of functions into one component achieves smooth operation without proportionally increasing overall device complexity.
Solution Approach 2:
The elastic part functions as a flexible structural element with alternately arranged bends that provides controlled movement while maintaining structural integrity. This flexible structure enables smooth movement through elastic deformation without requiring complex mechanical assemblies, resolving the contradiction between ease of operation and device complexity.

Function Achieved in This Case
The solution effectively reduces surface wear and corrosion, enhancing the reliability and longevity of electronic connections by stabilizing the contact between the connecting device and the target surface, thus improving the resistance to corrosion and maintaining stable contact resistance.
Implementation Method 1
an elastic part that may impart an elastic force to the contacting part as the contacting part is contacted
Implementation Method 2
causing surface wear to the target and hence fretting corrosion. Fretting corrosion may include granules produced by the surface wear oxidizing the surface of the target
