Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires are not securely positioned, then the machine structure remains simple and easy to assemble, but the wires may be accidentally pulled apart due to translational or rotational motion, causing electrical disconnection
Solution Approach 1:
The fixing device is divided into multiple functional components: a positioning seat with cavities for wire routing, gripping members with resilient terminal end portions for securing wires, and fastening units for attachment. This segmentation allows each component to perform its specific function efficiently while maintaining overall device reliability.
Solution Approach 2:
The resilient terminal end portions are inserted into cavities of the positioning seat, creating a nested structure where the gripping members fit within the positioning seat. This nesting arrangement secures the wires through multiple concentric containment levels, enhancing connection reliability without excessive complexity.
2Reliability
If wires are securely positioned using a fixing device, then electrical disconnection is prevented, but the device structure becomes more complex
Solution Approach 1:
The resilient terminal end portions utilize material elasticity parameters to achieve automatic gripping when inserted into the cavities. By selecting appropriate resilient materials, the device achieves reliable wire securing through material property optimization rather than complex mechanical structures, facilitating easier manufacturing.
Solution Approach 2:
The resilient terminal end portions automatically grip the wires through their elastic recovery force when inserted into the cavities, without requiring additional fastening operations or complex adjustment mechanisms. This self-gripping feature simplifies the manufacturing process while ensuring reliable electrical connections.
3Reliability
If resilient terminal end portions are used to grip wires, then secure positioning is achieved, but the gripping force must be carefully controlled to avoid wire damage
Solution Approach 1:
The resilient terminal end portions are designed with pre-calculated elastic deformation characteristics that provide cushioning during wire insertion. The material selection and geometric design ensure that the gripping force remains within safe limits throughout the wire installation and operation, preventing wire damage while maintaining secure positioning.
Solution Approach 2:
By optimizing the material elasticity modulus and the geometric dimensions of the terminal end portions, the gripping force parameters are carefully controlled to achieve reliable wire securing without exceeding the wire's mechanical strength limits, ensuring both reliability and ease of operation.
