Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional connector structure with pins and pin coupling member is used, then electrical connection between boards is achieved, but the structure becomes complicated and requires many components occupying large space
Solution Approach 1:
The patent merges the pin coupling member and the board into a single integrated structure. The pin housings are directly formed on the board body, eliminating the need for separate pin coupling members. This integration reduces the number of components and simplifies the overall connector structure while maintaining reliable electrical connections between pins on one board and corresponding pins on another board.
2Reliability
If a conventional connector structure with multiple components is used, then electrical connection is achieved, but the assembly requires large space and significant manufacturing resources
Solution Approach 1:
The patent combines multiple previously separate components into a single integrated board structure. The pin housings are directly formed on the board body, eliminating the need for separate pin coupling members and reducing the overall assembly space required.
Solution Approach 2:
The board body serves multiple functions: it provides structural support, contains embedded signal lines for electrical connection, and directly forms the pin housings that receive and secure the pins. This multi-functionality reduces the number of separate components needed and minimizes the overall assembly space.
3Reliability
If conventional connector structures are used in printed circuit board assemblies, then electrical connections are established, but the number of components and manufacturing complexity increases
Solution Approach 1:
The patent integrates the pin coupling function directly into the board body through molded pin housings, eliminating the need for separate pin coupling members. This reduction in component count simplifies the manufacturing process and reduces assembly steps while maintaining reliable electrical connections.
Solution Approach 2:
The pin housings are pre-formed and embedded in the board body during board manufacturing, before the final assembly process. This preliminary formation of the coupling structure simplifies subsequent assembly operations and reduces manufacturing complexity.
