Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detecting contact extends into the mating cavity to perform detection function, then the detecting function is achieved, but the detecting contact is easy to be destroyed by frequent outward pressure
Solution Approach 1:
The patent introduces a resilient contacting portion as an intermediary element between the detecting contact and the complementary connector. This resilient portion absorbs the outward pressure from the complementary connector through elastic deformation, preventing direct transmission of damaging forces to the detecting contact while still enabling detection functionality through electrical contact.
Solution Approach 2:
The resilient contacting portion is designed to provide beforehand cushioning by being positioned to contact the detecting contact before excessive force can be applied. The resilient material and structure are pre-configured to deform elastically under pressure, creating a protective buffer that prevents damage to the detecting contact during normal operation and mating cycles.
2Difficulty of detecting and measuring
If the detecting contact protrudes into the mating cavity for detection, then detection capability is improved, but the contact becomes vulnerable to external pressure and damage
Solution Approach 1:
The resilient contacting portion serves as a protective intermediary that allows the detecting contact to extend into the mating cavity for detection while preventing direct exposure to harmful external pressures. The resilient material absorbs and dissipates mechanical stresses, enabling the detecting contact to maintain its extended position for detection without suffering damage from connector mating forces.
Solution Approach 2:
The patent changes the mechanical parameters of the contacting structure by using resilient material with specific elastic properties. This allows the contacting portion to dynamically adjust its position and force transmission characteristics based on applied pressure, maintaining detection capability while preventing damage through parameter-based adaptation rather than static structural design.
