Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple support insulators and components are used in the support structure, then the mechanical and electrical performance can be enhanced, but the assembly time and device complexity increase
Solution Approach 1:
The patent combines multiple support insulators and structural components into a single integrated support structure. This monolithic design maintains the necessary mechanical strength and electrical insulation performance while eliminating the complexity of assembling multiple separate components, directly resolving the contradiction between reliability and device complexity.
2Reliability
If multiple support insulators and components are used in the support structure, then the mechanical and electrical performance can be enhanced, but the assembly time increases
Solution Approach 1:
By merging multiple components into a single integrated support structure, the patent eliminates the time-consuming assembly process of connecting multiple insulators and structural elements. The single-piece design maintains full mechanical and electrical performance while dramatically reducing installation time.
3Productivity
If a single structural element is used in the support structure, then the assembly process is simplified and assembly time is reduced, but the mechanical and electrical performance may be compromised
Solution Approach 1:
The patent successfully merges multiple functions (mechanical support, electrical insulation, structural stability) into a single support structure element. This integration maintains or enhances mechanical and electrical performance while simultaneously improving assembly efficiency, as the single element requires no assembly operations.
Solution Approach 2:
The support structure utilizes composite materials that provide both mechanical strength and electrical insulation properties in a single material system, enabling the single-element design to meet both structural and electrical performance requirements simultaneously.
