Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are used to connect circuit boards, then electrical connection is achieved, but the cost increases due to requiring two board end connectors and two cable end connectors
Solution Approach 1:
The patent merges the cable end connector and board end connector functions into a single integrated connector assembly. The connector includes a housing with a cable receptacle and a board end connector that are combined into one unit, reducing the total number of connectors from four (two cable end connectors and two board end connectors) to two (one integrated connector and one board end connector), thereby reducing cost and complexity while maintaining electrical connection reliability
2Reliability
If FFC or FPC is directly soldered to circuit board, then electrical connection is achieved, but the welding process becomes difficult and complex
Solution Approach 1:
The patent introduces an intermediary connector assembly that mediates between the FFC/FPC and the circuit board. Instead of directly soldering the FFC/FPC to the board, the connector provides an intermediate interface with press-fit or snap-fit mounting mechanisms. This intermediary structure simplifies the manufacturing process by replacing difficult welding operations with easier mechanical attachment methods, while still ensuring reliable electrical connection through the connector's contact elements
