Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If male and female connectors are used to establish electrical connection between electronic modules and backplane system, then electrical connection can be achieved, but signal transmission loss increases due to insertion losses in high-speed links
Solution Approach 1:
The patent extracts and eliminates the male and female connectors from the electrical connection path between electronic modules and the backplane system. By using a terminal connecting member with conductive terminals that directly contact the circuit board, the design removes the intermediate connector components that cause insertion losses, thereby reducing signal transmission loss while maintaining reliable electrical connection.
Solution Approach 2:
The terminal connecting member serves as a new intermediary component between the electronic modules and the backplane system. Instead of using traditional male-female connector pairs, the terminal connecting member with its conductive terminals provides a direct electrical interface to the circuit board, reducing the number of connection interfaces and minimizing signal transmission losses.
2Adaptability or versatility
If multiple groups of male and female connectors are used for communication among electronic modules, then electrical connection can be established, but the quantity of connectors increases leading to more signal transmission losses
Solution Approach 1:
The patent merges the functions of multiple connector groups into a single terminal connecting member. The terminal connecting member integrates multiple conductive terminals that can simultaneously establish electrical connections with multiple electronic modules and the backplane system, reducing the total quantity of connectors while maintaining full adaptability for various communication needs.
Solution Approach 2:
The terminal connecting member is designed with multi-functionality, where a single component can establish electrical connections for multiple different signal paths and communication channels. The conductive terminals on the terminal connecting member can serve various connection purposes, eliminating the need for multiple specialized connector groups.
