Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pressurization method is used to fix resistors in plastic core columns, then resistors can be fixed, but the fixing reliability is poor and additional manufacturing costs are incurred
Solution Approach 1:
The metal support wire's own flexibility and elasticity are utilized to achieve self-fixing function. The wire naturally bends and elastically deforms to clamp the resistor in place without requiring external pressurization devices, making the system self-sufficient and eliminating additional manufacturing steps.
Solution Approach 2:
The complex mechanical pressurization system is replaced by a simple elastic deformation mechanism of the metal wire. Instead of using external pressing devices, the wire's inherent elastic properties are harnessed to provide continuous clamping force, substituting a complex mechanical system with a simple elastic one.
2Reliability
If pressurization method is used to fix resistors, then resistors can be secured, but assembly complexity increases
Solution Approach 1:
The fixing function is extracted from the plastic core column structure itself and transferred to the metal support wire. The wire is designed with specific geometric features (bends, loops, or expanded ends) that provide the clamping capability, separating the support function from the fixing function and simplifying the overall assembly.
Solution Approach 2:
Instead of using an external device to pressurize and fix the resistor onto the rigid plastic structure, the invention inverts the approach by using the flexible metal wire to actively clamp onto the resistor. The wire becomes the active fixing element rather than the passive plastic structure.
3Ease of manufacture
If simple plastic core column structure is used, then manufacturing cost is reduced, but resistor fixation becomes unreliable
Solution Approach 1:
The solution combines the rigid plastic core column material with the flexible metal wire material to create a composite fixing system. The plastic provides structural support and insulation, while the metal wire provides elastic clamping force, leveraging the complementary properties of different materials to achieve both simplicity and reliability.
