Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If straight male connectors and curved female connectors are used in backplane systems, then signal interaction between electronic modules is achieved, but insertion loss and signal transmission loss occur due to mating gaps
Solution Approach 1:
The patent applies the dynamics principle by making the connector assembly movable relative to the mounting member through a floating connection mechanism. The connector can move along the insertion direction to dynamically adjust and eliminate mating gaps, thereby reducing signal transmission loss while maintaining reliable signal interaction between electronic modules
Solution Approach 2:
The patent changes the positional parameter of the connector by enabling it to move along the insertion direction. This parameter change allows the connector to adapt its position and eliminate mating gaps, resolving the contradiction between achieving signal interaction and preventing signal transmission loss
2Loss of energy
If gold finger design is adopted to reduce loss, then signal transmission loss is reduced, but demating risk increases due to potential gaps between gold finger and connector
Solution Approach 1:
The floating connection mechanism allows the connector assembly to move dynamically along the insertion direction, enabling it to maintain continuous contact with the gold finger and eliminate demating gaps, thereby improving mating stability while preserving the low-loss characteristics of the gold finger design
Solution Approach 2:
The elastic component provides beforehand cushioning by storing elastic potential energy that compensates for mating gaps and prevents demating, ensuring reliable contact between the connector and gold finger while maintaining the signal transmission benefits of the gold finger design
3Loss of energy
If floating connection mechanism is implemented, then signal transmission loss is reduced by absorbing mating gaps, but device complexity increases
Solution Approach 1:
The patent uses an elastic component (flexible element) to provide the floating connection functionality. This flexible element absorbs mating gaps through elastic deformation, reducing signal transmission loss while adding minimal structural complexity compared to rigid mechanical floating mechanisms
Solution Approach 2:
The elastic component acts as an intermediary between the connector and mounting member, providing the floating connection function through a simple elastic element rather than a complex mechanical mechanism, thereby reducing device complexity while effectively absorbing mating gaps
