Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a straight type connector is used with a simple structure, then the device complexity is reduced, but the force transmission from electrical wire to terminal cannot be prevented
Solution Approach 1:
The connector is divided into distinct functional segments: a rigid connecting member fixed to the casing, a flexible conductor portion, and a terminal portion. This segmentation allows the flexible conductor to absorb forces independently while the rigid portions maintain structural integrity and electrical connection, preventing force transmission to the terminal.
Solution Approach 2:
The flexible conductor acts as an intermediary element between the electrical wire and the terminal. It mediates the force transmission by absorbing external forces through its flexibility while maintaining electrical continuity, thereby protecting the terminal from force-induced contact failures.
2Reliability
If an L-shaped connector structure is used to prevent force transmission, then the reliability is improved, but the device complexity increases and it is difficult to apply to straight type connectors
Solution Approach 1:
The connector design provides a universal solution that can be applied to both straight type and L-shaped connectors. The combination of a rigid connecting member fixed to the casing and a flexible conductor creates a multi-functional structure that prevents force transmission while maintaining electrical connection, applicable across different connector geometries.
Solution Approach 2:
The flexible conductor is implemented as a flexible electrical pathway that can bend and deform to absorb external forces. This flexible element serves as a mechanical cushion between the rigid connector housing and the terminal, preventing force transmission while maintaining electrical connectivity in various connector configurations.
3Device complexity
If the electrical wire is drawn in the same direction as terminal insertion, then the connector structure is simplified, but force transmission to the terminal occurs
Solution Approach 1:
The flexible conductor introduces dynamic characteristics to the otherwise rigid connector structure. It can dynamically adjust its shape and absorb forces through elastic deformation, allowing the connector to handle external forces without transmitting them to the terminal, even when the electrical wire is drawn in the same direction as terminal insertion.
Solution Approach 2:
The flexible conductor changes the mechanical parameters of the electrical connection pathway. By introducing flexibility and compliance to the electrical wire routing, the system can accommodate external forces without rigid force transmission, effectively changing the force transmission characteristics while maintaining simplified wire routing.
