Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If perforation installation method is used to achieve electrical connection, then electrical connection is achieved, but further soldering is required and installation becomes more complex
Solution Approach 1:
The patent combines the electrical connection function and mechanical mounting function into a single integrated connector assembly. The connector directly mounts to the circuit board while simultaneously establishing electrical connections through its contact elements, eliminating the need for separate soldering operations and reducing installation complexity.
Solution Approach 2:
The connector assembly serves multiple functions simultaneously: it provides mechanical support for the cable assembly, establishes electrical connections between components, and secures the overall structure. This multi-functional design reduces the number of separate components and simplifies the installation process.
2Strength
If extrusion installation method is used, then structural strength is achieved, but large installation space is required and volume increases
Solution Approach 1:
The connector assembly features a nested structure where the contact elements are housed within a compact connector body, which in turn is integrated into the cable assembly. This nested arrangement maximizes structural strength while minimizing the overall volume and installation space required.
Solution Approach 2:
The connector utilizes thin-walled but structurally optimized housing designs that provide sufficient mechanical strength and protection for the internal contact elements while minimizing the external dimensions and overall volume of the assembly.
3Reliability
If traditional connector assembly is used, then electrical connection is established, but structure becomes complex and installation becomes difficult
Solution Approach 1:
The connector assembly is divided into distinct modular components including the connector body, contact elements, and cable assembly sections. This segmentation allows for simplified manufacturing, easier handling during installation, and straightforward replacement if needed, while maintaining reliable electrical connections.
Solution Approach 2:
The connector contacts are pre-positioned and pre-assembled within the connector housing before final installation. This preliminary assembly ensures proper alignment and connection geometry is achieved automatically during installation, reducing the skill level and time required for proper installation.
