Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a buckle is used to tightly press the cable connector onto the printed circuit board, then the electrical connection stability is improved, but the space occupied on the printed circuit board increases
Solution Approach 1:
The buckle is divided into two separate parts: a first part that is fixed to the printed circuit board, and a second part that is attached to the cable connector. This segmentation allows each part to be smaller and more compact, reducing the overall space required while maintaining the fastening function. The first part includes a first contact for electrical connection, integrating the fastening and electrical connection functions into a compact structure.
Solution Approach 2:
The first part of the buckle is nested within or integrated with the contact structure on the printed circuit board. The sidewalls of the first part can be positioned around or near the contacts, allowing the fastening mechanism to utilize the same spatial footprint as the electrical connection elements, thereby minimizing additional space requirements.
2Force
If a buckle is used to tightly press the cable connector onto the printed circuit board, then the contact pressure is improved, but the device complexity increases
Solution Approach 1:
The fastening function and electrical connection function are merged into a single integrated structure. The first part of the buckle incorporates both mechanical fastening elements (sidewalls for pressing) and electrical connection elements (first contact), eliminating the need for separate fastening and electrical connection components. This reduces overall device complexity while maintaining adequate contact pressure through the integrated design.
