Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamping seats are used to fix metal supporting wires, then the fixing reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent removes the clamping seat component entirely and extracts the wire fixation function directly into the plastic seat body through integrated wire guide holes with crimped edges. This eliminates the need for separate clamping seats while maintaining wire fixation capability, thereby reducing device complexity and assembly steps.
Solution Approach 2:
The patent merges the wire guidance and wire fixation functions into a single integrated structure within the plastic seat. The wire guide holes are directly formed in the plastic seat with crimped edges that perform both guiding and securing functions, combining multiple functions into one component to reduce overall assembly complexity.
2Reliability
If clamping seats are used to fix metal supporting wires, then the fixing reliability is improved, but the manufacturing cost increases
Solution Approach 1:
By removing the clamping seat component, the patent reduces the number of parts that need to be manufactured, inventoried, and assembled. This directly lowers manufacturing costs while the crimped wire guide holes maintain adequate fixation reliability for the application.
Solution Approach 2:
The patent uses the plastic seat material itself to provide the fixation function through molded-in wire guide holes with crimped edges, replacing expensive metal clamping seats with a cost-effective plastic integration solution that achieves sufficient fixation for the intended application lifecycle.
3Reliability
If multiple components are used for wire fixation, then the fixing reliability is improved, but the assembly process becomes more complex
Solution Approach 1:
The patent combines wire guidance and wire fixation into a single integrated feature within the plastic seat structure. The wire guide holes with crimped edges perform both functions simultaneously, eliminating the need for separate clamping seats and reducing assembly steps, thereby improving assembly convenience while maintaining fixation reliability.
4Reliability
If additional components are added for wire fixation, then the fixing reliability is improved, but the volume of the device increases
Solution Approach 1:
By removing the separate clamping seat component, the patent eliminates the additional volume that would be required for that part. The integrated wire guide holes within the plastic seat maintain fixation functionality while minimizing the overall device volume by eliminating redundant components.
