Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If board-to-board connectors are designed to accommodate large axial and radial tolerances, then adaptability and ease of installation are improved, but manufacturing precision and structural complexity increase
Solution Approach 1:
The connector is divided into multiple independent components: clamping socket, fixed socket, adapter, insulators, and conductors. Each component can be manufactured separately with standard tolerances and assembled to achieve the required tolerance accommodation, reducing individual manufacturing complexity while maintaining overall adaptability
Solution Approach 2:
The adapter serves as an intermediary component between the clamping socket and fixed socket, providing mechanical alignment and electrical connection. This intermediate element absorbs and compensates for axial and radial tolerances, allowing the end components to maintain simpler structures while achieving high adaptability
2Adaptability or versatility
If board-to-board connectors accommodate large axial and radial tolerances, then adaptability is improved, but product cost increases
Solution Approach 1:
The connector uses standardized coaxial structures throughout (outer conductors, inner conductors, insulators) that can be manufactured using common processes and materials. This homogeneity allows for economies of scale and reduced tooling costs while maintaining the ability to accommodate tolerances through the overall assembly design
Solution Approach 2:
The adapter component performs multiple functions simultaneously: mechanical support, electrical connection, alignment reference, and tolerance compensation. This multi-functionality reduces the need for additional specialized components, lowering overall product cost while maintaining high adaptability
