Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a braided wire is used to absorb positional displacement of conductive members, then the terminal block can accommodate misalignment, but the length of the braided wire increases the overall size of the terminal block
Solution Approach 1:
The terminal body transitions from a linear braided wire structure to a multi-dimensional folded plate structure with first, second, and third plate portions arranged in different spatial planes. This dimensional transformation allows the terminal to absorb displacement in multiple directions while maintaining a compact footprint, as the folded structure can deform through angular changes rather than requiring extended linear length.
Solution Approach 2:
The terminal body's plate portions are folded and nested within each other, with the first plate portion connected to the second, and the second to the third, creating a compact nested arrangement. This nesting allows the terminal to maintain a small overall size while the nested structure can expand and deform to accommodate positional displacement of conductive members.
2Adaptability or versatility
If a braided wire is used to allow movement of terminals, then positional displacement can be absorbed, but the device complexity increases due to the need for additional components
Solution Approach 1:
The terminal body merges multiple functional elements into a single integrated folded structure. The first, second, and third plate portions are all part of one continuous terminal body made from a single belt-like conductive material, eliminating the need for separate braided wire components and multiple assembly steps. This merging reduces device complexity while maintaining the displacement absorption capability.
Solution Approach 2:
The terminal body incorporates dynamic flexibility through its folded plate structure, which can deform elastically to accommodate positional displacement. The coupling portions between plate portions allow angular deformation, enabling the terminal to adapt dynamically to misalignment without requiring complex mechanical joints or additional movable components.
3Ease of manufacture
If the terminal body is made from a single belt-like material bent into a spiral shape, then manufacturing is simplified, but the structural precision required for proper deformation increases
Solution Approach 1:
The terminal body is segmented into distinct functional regions (first plate portion, second plate portion, third plate portion, and coupling portions) that are formed in sequence during the bending process. This segmentation allows each portion to be optimized for its specific function while maintaining a unified manufacturing process from a single belt-like material, balancing manufacturing simplicity with structural precision.
