Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal is designed with high elasticity to handle position offsets, then the flexibility is improved, but the current capacity is compromised and large-current transmission fails
Solution Approach 1:
The terminal is divided into multiple sections with different functions: a connection section with bent portions for flexibility and elasticity, and fixed sections with plate structures for current conduction. This segmentation allows each part to optimize for its specific function without compromising the other.
Solution Approach 2:
Different portions of the terminal have different structural characteristics: the connection section has reduced width and bent portions for elasticity, while the fixed sections have increased width and plate structures for current capacity. This local quality differentiation resolves the contradiction between flexibility and power transmission.
2Power
If the terminal width is increased to improve current capacity, then the power transmission is improved, but the elasticity to handle position offsets is reduced
Solution Approach 1:
The terminal structure is segmented into connection sections with smaller width for elasticity and fixed sections with larger width for current capacity. This allows the overall terminal to achieve both high current capacity and sufficient elasticity for position offset compensation.
Solution Approach 2:
The terminal has non-uniform width distribution: narrower at the connection section for flexibility and wider at the fixed sections for current conduction. This local quality variation enables simultaneous optimization of both power transmission and elastic deformation capability.
3Ease of manufacture
If the terminal structure is simplified to ease manufacturing, then the ease of manufacture is improved, but the ability to maintain electrical connection stability under external forces is reduced
Solution Approach 1:
The terminal uses parameter optimization within the same material and basic structure: specific width ratios, bent portion radii, and plate thickness values are selected to achieve both manufacturing feasibility and connection reliability. This avoids complex multi-material structures while maintaining performance.

AI summary
A floating-type board-to-board receptacle connector includes a fixed base, a floating base, and receptacle power terminals. The floating base is in a through groove of the fixed base. The receptacle power terminal includes a contact section, a first fixed section, a second fixed section, a first bent portion, an inclined portion, and a second bent portion. The first fixed section is engaged with the floating base, and the second fixed section is engaged with the fixed base. The contact section extends toward an interior of the floating base from the first fixed section, and the first bent portion extends toward the inclined portion from the first fixed section. Two ends of the second bent portion respectively extend toward the inclined portion and the second fixed section. The second fixed section is a continuous plate. A width of the second bent portion is less than that of the second fixed section.
