Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If co-packaged optical transceiver components are connected to motherboards via cables and connectors, then the connection is established, but the signal transmission path becomes long and transmission efficiency deteriorates
Solution Approach 1:
The invention extracts and eliminates the intermediate cables and connectors from the signal transmission path. By directly mounting the optoelectronic transceiver module onto the mainboard through the interposer module, the patent removes the unnecessary transmission medium, thereby shortening the signal path and improving transmission efficiency while maintaining reliable electrical connection.
Solution Approach 2:
The invention merges the previously separate components (optoelectronic transceiver module, interposer module, and mainboard) into an integrated assembly. The interposer module serves as a unified connection platform that directly bridges the transceiver module and mainboard, eliminating the need for external cables and connectors, thus reducing transmission path length and improving efficiency.
2Ease of repair
If co-packaged optical transceiver components are connected via cables and connectors, then connection is established, but repair and replacement become difficult
Solution Approach 1:
The invention segments the system into modular components: the optoelectronic transceiver module, the interposer module, and the mainboard. This segmentation allows the transceiver module to be independently removed and replaced by simply detaching it from the interposer module, greatly simplifying repair and replacement procedures while maintaining a structured assembly hierarchy.
Solution Approach 2:
The invention introduces dynamic, detachable connection mechanisms through the limiting members and fixing structure. The limiting members can be easily moved or disengaged to release the transceiver module, transforming a previously static and complex assembly into a dynamic, easily reconfigurable system that facilitates quick repair and replacement.
3Stability of the object's composition
If limiting members are used to secure the interposer module and optoelectronic transceiver module, then connection stability is improved, but assembly complexity increases
Solution Approach 1:
The invention introduces the interposer module as an intermediary component between the optoelectronic transceiver module and the mainboard. This interposer module serves as a mediator that provides a standardized platform for connection, simplifying the overall assembly process while ensuring stable electrical and mechanical connections through its integrated design with the limiting members.

AI summary
An electrical connector structure, adapted for connecting an optoelectronic transceiver module on a mainboard, includes an interposer module and a fixing structure. The interposer module includes a first board and a second board assembled with each other, and at least a terminal module. A first terminal arm of the terminal module extends out of the first board, and a second terminal arm extends out of the second board. The fixing structure includes a pair of fixing walls, a plurality of first limiting members, and a second limiting member. The interposer module and the optoelectronic transceiver module are detachably arranged on the fixing structure and located on the mainboard, and the first limiting members press the second board, and the second limiting member presses the optoelectronic transceiver module, which in turn shortens a signal transmission path.
