Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional protectors with rigid base walls are used, then the structure is simple and easy to manufacture, but the holding force for electric wires is insufficient
Solution Approach 1:
The base walls are designed to be elastically deformable rather than rigid, allowing them to dynamically adapt to the electric wires' outer shapes. This dynamic characteristic enables the base walls to conform to irregular wire configurations while maintaining structural integrity, thereby increasing holding force without significantly complicating the overall device structure
Solution Approach 2:
The patent changes the physical parameter of the base walls from rigid to elastically deformable. This parameter change allows the base walls to undergo elastic deformation when electric wires are inserted, enabling them to wrap around and hold the wires securely. The elastic deformation capability is achieved through selective material selection and appropriate thickness design, maintaining manufacturing simplicity while dramatically improving wire retention
2Reliability
If elastically deformable base walls are used to increase holding force, then wire retention is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent utilizes elastic deformation as a controlled parameter change that occurs naturally during the wire insertion process. The base walls are designed with specific material properties and thickness to ensure they deform to an appropriate degree when wires are inserted, achieving reliable wire retention without requiring complex control mechanisms or high manufacturing precision
Solution Approach 2:
The elastically deformable base walls perform the function of adapting to wire shapes automatically through their own elastic properties. When electric wires are inserted, the base walls self-deform to conform to the wires' outer shapes without requiring external adjustment mechanisms, complex assembly procedures, or high-precision manufacturing tolerances
