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 size of the terminal block increases
Solution Approach 1:
The terminal body is designed as a three-dimensional spiral structure where multiple plate portions are arranged in different spatial layers. This allows the terminal to absorb positional displacement in multiple directions simultaneously without requiring excessive length in any single dimension, thus reducing the overall terminal block size while maintaining adaptability.
Solution Approach 2:
The terminal body incorporates a nested spiral configuration where plate portions are arranged concentrically around a central axis. The first, second, and third plate portions are positioned at different radial distances and angular orientations, creating a compact nested structure that provides multi-directional flexibility within a small volume.
2Adaptability or versatility
If the terminal body is designed with multiple plate portions and coupling elements for multi-directional deformation, then positional displacement can be absorbed effectively, but the manufacturing complexity increases
Solution Approach 1:
The terminal body is divided into multiple discrete plate portions (first, second, and third plate portions) connected by coupling elements. Each plate portion can deform independently in response to positional displacement, providing multi-directional adaptability. The segmentation allows complex deformation behavior to be achieved through simple, repeatable structural units.
3Volume of moving object
If a compact terminal body design is implemented, then the terminal block size is reduced, but the ability to absorb positional displacement may be compromised
Solution Approach 1:
Different regions of the terminal body are designed with different structural characteristics. The plate portions have specific geometric features (such as non-circular cross-sections and varying thicknesses) that enable localized deformation. This allows the compact terminal to absorb positional displacement effectively by concentrating flexibility where needed while maintaining structural integrity elsewhere.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively absorbs positional displacement of conductive members, ensuring reliable electrical connections while reducing the overall size of the terminal block, and can be easily produced through a bending process.
Implementation Method 1
the braided wire 103 deforms and allows the first terminal 101 to move with respect to the main housing 104. This can absorb the positional displacement of the first conductive member with respect to the first terminal 101
