Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional substation frame design is used, then structural strength and stability are ensured, but material consumption increases and construction cost rises
Solution Approach 1:
The patent applies composite insulating materials that integrate both mechanical support and electrical insulation functions. The frame uses composite materials combining high strength characteristics with excellent insulation properties, allowing reduction of material quantity while maintaining structural strength and electrical insulation performance.
2Adaptability or versatility
If conventional substation frame design is used, then adequate wire attachment capacity is provided, but land occupation area increases
Solution Approach 1:
The patent utilizes three-dimensional space utilization by extending wire attachment assemblies in lateral directions from the supporting posts. This dimensional approach allows multiple wires to be attached without increasing the footprint area, as wires are arranged in spatial configurations utilizing height and lateral extensions rather than requiring additional ground area.
Solution Approach 2:
The supporting posts are designed with multi-functional capabilities, serving both as structural support elements and as mounting points for wire attachment assemblies. The posts integrate multiple functions including mechanical support, electrical insulation, and wire attachment, thereby increasing adaptability without proportionally increasing land occupation.
3Reliability
If conventional substation frame design is used, then reliable electrical insulation is achieved, but construction cost increases
Solution Approach 1:
The patent employs composite insulating materials that provide reliable electrical insulation while being cost-effective. These composite materials integrate insulation properties with structural characteristics, reducing the need for separate insulation components and simplifying manufacturing processes, thereby lowering construction costs while maintaining insulation reliability.
Solution Approach 2:
The patent merges structural support functions and electrical insulation functions into integrated components. The frame structure itself incorporates insulation properties through composite materials and design configurations, eliminating or reducing separate insulation elements and simplifying the overall construction process and cost structure.
