Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connectors and wires are used for OCuLink interface connection, then electrical connection is established, but the total length is hard to be shortened and installation difficulty increases
Solution Approach 1:
The circuit board is divided into a first rigid circuit board and a second flexible circuit board, with the flexible board extending from the rigid board to provide connection. This segmentation allows the connection structure to be shortened while maintaining electrical connectivity and reducing installation complexity.
Solution Approach 2:
The flexible circuit board extends in a different spatial dimension from the rigid circuit board, allowing the connection to be achieved with reduced total length while maintaining the necessary electrical pathways and connection points.
2Ease of manufacture
If connectors and wires are used for OCuLink interface connection, then electrical connection is established, but cost increases
Solution Approach 1:
The connection function is merged into the flexible circuit board itself, eliminating the need for separate connectors and wires. This integration reduces the number of components, simplifies the connection structure, and lowers manufacturing cost while maintaining electrical connectivity.
Solution Approach 2:
The flexible circuit board serves multiple functions: it provides electrical connection, structural support, and spatial flexibility. This multi-functionality eliminates the need for separate connector components, reducing both device complexity and manufacturing cost.
3Reliability
If devices are connected to OCuLink interface connector, then connection is established, but stability decreases due to naked and suspended connector part
Solution Approach 1:
The flexible circuit board provides inherent mechanical support and cushioning to the connector before connection is made. This pre-support prevents the connector from being naked and suspended, reducing vibration sensitivity and improving connection stability from the outset.
Solution Approach 2:
The flexible circuit board acts as an intermediary between the rigid circuit board and the connector, providing mechanical support and reducing the impact of vibrations. This intermediary structure prevents direct transmission of harmful vibrations to the connector, improving reliability.

AI summary
An oculink electronic device having a flexible circuit board includes an oculink connector, a first rigid circuit board, a second rigid circuit board and the flexible circuit board. The first rigid circuit board is connected with the oculink connector. The flexible circuit board is extended from the first rigid circuit board and the second rigid circuit board and disposed between the first rigid circuit board and the second rigid circuit board. Therefore, not only the assembling steps are reduced, but also the total length is significantly shortened. The rotatable characteristic is provided, and the space requirement of installation is reduced.
