Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a MUX (or SS switch) is built into the silicon for super speed signaling, then the connector can support super speed signaling, but the cost increases and signal degradation occurs
Solution Approach 1:
The patent extracts the MUX/SS switch functionality from the silicon and replaces it with a simple mechanical flippable connector structure. The connector can be physically flipped to switch between different contact configurations, eliminating the need for complex electronic switching components while maintaining super speed signaling capability.
Solution Approach 2:
Instead of using electronic switching (MUX/SS switch) to change signal paths, the patent inverts the approach by using mechanical flipping of the connector itself to achieve the same function. This mechanical inversion replaces complex electronic control with a simple physical operation.
2Reliability
If a MUX (or SS switch) is built into the silicon for super speed signaling, then the connector can support super speed signaling, but the cost increases
Solution Approach 1:
The patent removes the expensive MUX/SS switch components from the design and replaces them with a simple mechanical flippable connector. This extraction of complex electronic components significantly reduces manufacturing cost while preserving the essential super speed signaling functionality through mechanical means.
Solution Approach 2:
The patent employs a simple mechanical flippable connector structure that is inexpensive to manufacture compared to silicon-based MUX switches. The mechanical components can be easily produced using standard manufacturing processes, making the overall system more cost-effective.
3Adaptability or versatility
If pads are arranged in a diagonally symmetrical manner on the mating tongue, then the connector becomes flippable, but the manufacturing precision requirements increase
Solution Approach 1:
The patent uses diagonal symmetry in the pad arrangement, which is a form of controlled asymmetry. By positioning pads at specific diagonal positions on the mating tongue, the connector achieves flippable capability while the symmetry itself provides a self-aligning feature that reduces the actual manufacturing precision requirements compared to completely asymmetric arrangements.
Solution Approach 2:
The diagonally symmetrical pad arrangement serves multiple functions: it enables the connector to be flipped, maintains proper electrical contact alignment, and provides mechanical guidance for insertion. This multi-functional design reduces the need for additional precision features.
