Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a socket is used to connect the cable to the circuit board, then the connection is stable and reliable, but the height of the assembly increases and heat dissipation becomes difficult
Solution Approach 1:
The patent removes the socket component from the cable assembly, extracting the problematic element that caused both height increase and heat dissipation issues. The cable is directly connected to the circuit board without an intermediate socket, eliminating the source of thermal accumulation while maintaining connection functionality through direct PCB mounting
2Reliability
If a socket is used to connect the cable to the circuit board, then the connection is stable, but the number of contact interfaces increases and impedance discontinuity points increase
Solution Approach 1:
The patent merges the cable connection directly with the circuit board by eliminating the socket interface. The cable is integrated onto the PCB through direct mounting, reducing the number of separate contact interfaces from multiple (cable-socket, socket-PCB) to a single direct connection, thereby reducing impedance discontinuity points and simplifying the overall connection structure
3Device complexity
If the cable is directly connected to the PCB through a fisheye structure, then the number of sockets is reduced, but the component cannot be detached from the PCB
Solution Approach 1:
The patent segments the cable connection into a separate, detachable component that can be independently mounted and removed from the PCB. Rather than permanently integrating the cable through a fisheye structure, the design allows the cable assembly to be separated from the board, enabling maintenance and rework without damaging the PCB or requiring complex rework procedures
