Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soldering or adhering is used to connect components, then connection strength and reliability are improved, but assembly complexity and time increase
Solution Approach 1:
The patent replaces the mechanical soldering/adhering system with a press-fit mechanical connection system. The flexible electrically conductive member is pressed against contact pads on the circuit board to establish electrical connection, eliminating the need for soldering or adhesive processes while maintaining reliable electrical connectivity.
Solution Approach 2:
The patent utilizes the flexibility parameter of the electrically conductive member to enable press-fit connection. By making the conductive member flexible rather than rigid, it can be easily pressed against the circuit board contact pads and maintains reliable electrical connection through continuous contact pressure.
2Strength
If soldering or adhering is used to connect components, then connection strength is improved, but assembly time and productivity decrease
Solution Approach 1:
The patent replaces time-consuming soldering or adhering processes with a rapid press-fit mechanical connection. The flexible electrically conductive member can be quickly inserted and pressed against the circuit board contact pads, dramatically reducing assembly time while maintaining sufficient connection strength for electrical connectivity.
Solution Approach 2:
The patent separates the electrically conductive member into a flexible, removable component that can be independently assembled and disassembled. This segmentation allows the conductive member to be quickly connected to the circuit board without affecting other components, enabling rapid assembly and maintenance operations.
3Loss of time
If removable press mechanism is used to connect components, then assembly time and ease of maintenance are improved, but connection reliability may decrease
Solution Approach 1:
The patent utilizes the flexibility parameter of the electrically conductive member to maintain reliable electrical connection through continuous contact pressure. The flexible material deforms elastically under press-fit force, ensuring sustained electrical contact with the circuit board contact pads even during thermal cycling and vibration, thereby maintaining connection reliability.
Solution Approach 2:
The patent employs a simple, inexpensive flexible electrically conductive member that can be easily replaced if needed. The press-fit design allows for quick replacement of the conductive member without requiring complex tools or processes, maintaining system reliability through easy maintainability rather than permanent installation.

AI summary
An optical transceiver includes a photoelectric converter, an interposer and a circuit board. The interposer is disposed on the photoelectric converter. The interposer includes a board member and a flexible electrically conductive member disposed on the board member, and the photoelectric converter is electrically connected to the flexible electrically conductive member. The circuit board is disposed on a side of the interposer. The flexible electrically conductive member is remove-ably pressed against the circuit board so that the flexible conductive member is electrically connected to the circuit board.
