Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional socket connector uses soldering for assembly, then connection reliability is improved, but assembly convenience and waterproof performance deteriorate
Solution Approach 1:
The patent merges the socket connector with a circuit board to form an integrated assembly. The connector body is directly mounted on the circuit board, eliminating the need for separate soldering operations between the connector and the electronic device housing. This integration maintains reliable electrical connections while simplifying the overall assembly process and enabling waterproof sealing.
2Reliability
If conventional socket connector uses soldering for assembly, then connection reliability is improved, but waterproof performance deteriorates
Solution Approach 1:
The socket connector is integrated with the circuit board as a unified assembly. The circuit board itself serves as the mounting structure, eliminating gaps and interfaces between separate components that would compromise waterproof sealing. This integration allows for continuous sealing around the entire connector assembly, achieving IPX7 waterproof rating while maintaining reliable electrical connections.
3Ease of operation
If charging circuit is integrated to conventional socket connector, then assembly convenience is improved, but device complexity increases
Solution Approach 1:
The circuit board serves multiple functions simultaneously: it provides the structural mounting base for the socket connector, establishes electrical connections between terminals, and integrates the charging circuit functionality. This multi-functionality reduces the number of separate components needed, simplifying assembly while the modular circuit board design keeps the overall structure manageable and maintainable.
