Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If punch riveting process is used to couple conductive terminal and metal plate, then connection strength is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent extracts the complex punch riveting process and replaces it with a simple embedding structure where conductive pins are directly embedded into the insulating base with their ends exposed through slots. This eliminates the need for separate metal plates and riveting operations, thereby reducing manufacturing complexity while maintaining connection strength through the embedded structure.
Solution Approach 2:
The patent merges the conductive terminal and metal plate into a single integrated structure where the conductive pin serves both as the electrical conductor and the structural element that was previously separated into two components. This integration eliminates the need for coupling processes like riveting, simplifying the manufacturing procedure while maintaining structural integrity.
2Strength
If punch riveting process is used to couple conductive terminal and metal plate, then connection strength is improved, but manufacturing cost increases
Solution Approach 1:
The patent removes the expensive punch riveting process and specialized tools from the manufacturing procedure, replacing them with a simple embedding process where conductive pins are placed into pre-formed holes in the insulating base. This extraction of the complex riveting operation significantly reduces manufacturing cost while maintaining adequate connection strength through the embedded structure.
Solution Approach 2:
The patent adopts a simpler, more economical manufacturing approach using basic embedding rather than expensive riveting equipment. The design accepts that the conductive pins are permanently embedded in the insulating base during manufacturing, eliminating the need for costly riveting tools and operations, thereby reducing overall manufacturing cost.
3Reliability
If conductive terminal is coupled to metal plate by riveting, then electrical connection is established, but connection reliability deteriorates due to loosening and sparks
Solution Approach 1:
The patent extracts the problematic interface between conductive terminal and metal plate that generates sparks during riveting. By eliminating the metal plate and using direct embedding of conductive pins into the insulating base, the design removes the source of sparks and high temperature generation, improving safety and connection reliability.
Solution Approach 2:
The patent provides beforehand protection by embedding the conductive pins securely into the insulating base with slots that cover the exposed ends. This pre-arranged protective structure prevents loose connections and potential sparking before they can occur during operation, thereby improving connection reliability and safety.
