Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a contact is made rigid to ensure stable electrical connection, then electrical reliability is improved, but flexibility and ability to accommodate misalignment deteriorate
Solution Approach 1:
The contact is divided into multiple sections with different rigidity characteristics. The first adjusting part has higher electrical conductivity and forms a first slit, while the second adjusting part has lower electrical conductivity and forms a second slit. This segmentation allows different portions of the contact to have different flexibility levels, enabling the contact to accommodate misalignment while maintaining stable electrical connection in the rigid portions.
Solution Approach 2:
Different portions of the contact are given different local properties. The first adjusting part is designed with higher electrical conductivity and specific slit configuration, while the second adjusting part has lower electrical conductivity and different slit configuration. This local quality differentiation enables the contact to exhibit both flexibility for misalignment accommodation and rigidity for stable electrical connection in different regions.
2Adaptability or versatility
If a contact is made flexible to accommodate misalignment, then adaptability is improved, but electrical conductivity and signal transmission quality deteriorate
Solution Approach 1:
The contact is segmented into a first adjusting part with higher electrical conductivity and a second adjusting part with lower electrical conductivity. Each part has different slit configurations that provide appropriate flexibility levels. This segmentation ensures that the high-conductivity portions maintain good electrical connection while the low-conductivity portions provide the necessary flexibility for misalignment accommodation.
Solution Approach 2:
Different local regions of the contact are assigned different electrical conductivity properties and flexibility characteristics. The first adjusting part maintains higher conductivity with controlled flexibility, while the second adjusting part has lower conductivity with different flexibility characteristics. This local quality approach allows the contact to simultaneously achieve good electrical conductivity and misalignment accommodation in different regions.
3Reliability
If slits are added to adjust characteristic impedance, then signal transmission quality is improved, but structural strength and flexibility control become more difficult
Solution Approach 1:
The contact is divided into multiple adjusting parts, each with specifically designed slits. The first adjusting part has a first slit configured to adjust characteristic impedance in its region, while the second adjusting part has a second slit for impedance adjustment in its region. This segmentation allows precise control of characteristic impedance across different portions of the contact without requiring complex overall结构设计.
Solution Approach 2:
Different portions of the contact are given different slit configurations to locally adjust characteristic impedance. The first slit in the first adjusting part and the second slit in the second adjusting part are designed with different characteristics to achieve appropriate impedance control in their respective regions. This local quality approach simplifies the overall design by allowing independent optimization of impedance characteristics in different contact regions.

AI summary
A fixed insulator includes a plurality of first fixing grooves disposed along an arrangement direction in which a plurality of contacts are arranged, and partition walls each disposed between two adjacent contacts. A movable insulator includes a plurality of second fixing grooves disposed along the arrangement direction. The contacts each include a first base portion supported by a corresponding one of the first fixing grooves, a second base portion supported by a corresponding one of the second fixing grooves, a first arm portion connected to the first base portion and disposed between two corresponding adjacent ones of the partition walls, and a second arm portion connected to the first arm portion and the second base portion. A largest width of the first arm portion is smaller than a largest width of the second arm portion.
