Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current connectors are designed for high-frequency transmissions, then transmission quality is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent changes the physical state of the impedance improving element from rigid to deformable, allowing it to be compressed during assembly. This parameter change enables the element to adapt to manufacturing tolerances while maintaining consistent electrical characteristics for high-frequency transmissions, thus improving transmission quality without requiring complex precision manufacturing
Solution Approach 2:
The impedance improving element is designed with deformable sections that can dynamically adjust their position and shape during the crimping process. This dynamic capability allows the element to compensate for variations in cable diameter and connector assembly tolerances, maintaining optimal electrical performance for high-frequency signals without increasing structural complexity
2Reliability
If precision manufacturing is used to achieve consistent impedance, then transmission reliability is improved, but production cost increases
Solution Approach 1:
The patent incorporates an impedance improving element with deformable sections that act as a cushioning mechanism before electrical contact is made. This element compensates for manufacturing tolerances in cable diameter and connector dimensions, ensuring consistent impedance matching without requiring precision manufacturing processes, thereby reducing production costs while maintaining reliability
3Adaptability or versatility
If deformable impedance improving element is used, then assembly tolerance compensation is improved, but structural complexity increases
Solution Approach 1:
The patent uses a deformable impedance improving element with flexible sections that can be compressed radially during assembly. This flexible structure allows the element to adapt to variations in cable and connector dimensions, providing tolerance compensation through simple radial compression rather than complex mechanical adjustments, thus maintaining structural simplicity while improving adaptability
