Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If solder wax is used to connect the cable to the contact, then the connection is easier to manufacture, but the conductive properties vary and high-frequency transmission performance deteriorates
Solution Approach 1:
The patent removes the solder wax intermediary from the connection structure. Instead of using solder wax to connect the cable to the contact, the invention directly connects the conductive wire to the contact terminal through a holding member, eliminating the source of conductive property variation while maintaining manufacturing feasibility
Solution Approach 2:
The holding member serves as a new intermediary structure between the cable and contact. This holding member provides a stable, controlled connection path that replaces the problematic solder wax, ensuring consistent conductive properties while still facilitating the connection process
2Ease of manufacture
If solder wax is used to connect the cable to the contact, then the connection process is simpler, but high-frequency transmission performance varies
Solution Approach 1:
The invention extracts and eliminates the solder wax from the connection process. By removing this variable element, the patent achieves consistent conductive properties across different assemblies while maintaining a straightforward manufacturing process through direct connection methods
Solution Approach 2:
The patent changes the connection parameter from using a variable-material connection (solder wax with inconsistent properties) to a fixed-structure connection (holding member with controlled geometry). This parameter change ensures consistent conductive properties while keeping the manufacturing process simple
