Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mounting mechanisms are used to fix the circuit board, then the assembly process is simple, but the durability and stability of the circuit board are insufficient
Solution Approach 1:
The support members are made of conductive material that provides both mechanical support and electrical connection functions, combining structural and electrical properties into a single component that enhances durability while maintaining assembly simplicity
Solution Approach 2:
The conductive support members serve multiple functions simultaneously: they provide mechanical support for the circuit board, establish electrical connections to ground lines, and offer electromagnetic shielding. This multi-functionality improves reliability without significantly increasing assembly complexity
2Reliability
If inadequate protection mechanisms are used for the circuit board, then the device structure is simple, but the protection and stability of the circuit board are insufficient
Solution Approach 1:
The conductive support members act as intermediary components between the circuit board and the housing, providing both mechanical support and electrical connection. This intermediary structure enhances stability while keeping the overall device structure relatively simple
Solution Approach 2:
The conductive support members combine mechanical support functionality with electrical conductivity, creating a composite solution that provides both structural stability and electrical protection without requiring separate components for each function
3Reliability
If multiple separate components are used for support and electrical connection, then the electrical connectivity is ensured, but the assembly time is increased
Solution Approach 1:
The conductive support members perform both mechanical support and electrical connection functions in a single component, eliminating the need for separate support structures and electrical connectors. This reduces the number of assembly steps and decreases assembly time while ensuring reliable electrical connectivity
Solution Approach 2:
The patent merges the support function and electrical connection function into a single integrated conductive support member, combining multiple components into one that reduces assembly complexity and time while maintaining electrical connectivity reliability
