Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of antennas and RF components increases, then communication performance is improved, but spatial constraints and tolerance accumulation lead to performance degradation
Solution Approach 1:
The connection structure employs elastic members that can dynamically adjust their position and deformation to compensate for tolerance accumulation. The elastic member deforms elastically under compression to maintain stable electrical contact between RF components despite dimensional variations, transforming a static rigid connection into a dynamic adaptive connection that absorbs tolerance errors.
Solution Approach 2:
The invention changes the physical state and mechanical properties of the connection structure by introducing elasticity. The elastic member's deformation characteristics (compression, bending) are utilized to convert rigid dimensional constraints into flexible mechanical responses, allowing the system to accommodate tolerance variations while maintaining reliable electrical connection.
2Reliability
If the number of antennas and RF components increases, then communication performance is improved, but device complexity and assembly difficulty increase
Solution Approach 1:
The invention merges the signal connection function and ground connection function into a single integrated elastic member structure. The elastic member simultaneously provides electrical connection for signal transmission and grounding, reducing the number of separate components and simplifying the overall connection structure while maintaining reliable communication performance.
Solution Approach 2:
The elastic member serves multiple functions: it provides electrical connection, mechanical support, tolerance compensation, and grounding simultaneously. This multi-functional design reduces device complexity by eliminating the need for separate components for each function, making the connection structure more efficient and easier to assemble.
3Ease of manufacture
If rigid connection structures are used, then assembly is simple, but tolerance accumulation causes performance degradation
Solution Approach 1:
The elastic member is designed to beforehand cushion against tolerance accumulation by its inherent elasticity. Before assembly, the elastic member is configured to be compressible, and during assembly, it naturally deforms to absorb dimensional variations between components. This prior cushioning capability ensures stable electrical connection without requiring complex precision machining or adjustment procedures.
