Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional attachment methods for polarity resistors are used, then the structural stability is maintained, but the assembly complexity increases and flexibility is reduced
Solution Approach 1:
The support structure is divided into multiple support elements that can be independently positioned and adjusted. Each support element can be separately attached to the insulating cylinder, allowing flexible configuration of polarity resistors without complex integrated structures
Solution Approach 2:
The support elements are designed with adjustable positioning capabilities, enabling dynamic reconfiguration of the polarity resistor arrangement. This allows the same support structure to adapt to different tap changer designs and polarity resistor configurations
2Ease of manufacture
If modular carrier modules with joining areas are used, then the ease of assembly is improved, but the device complexity increases
Solution Approach 1:
The support structure is segmented into modular carrier modules with standardized joining areas. These modules can be independently manufactured and then easily assembled together, simplifying the manufacturing process while the modular nature actually reduces overall structural complexity through standardization
Solution Approach 2:
The joining areas are designed with universal compatibility, allowing the same carrier module design to be used in different configurations and positions. This multi-functionality reduces the need for multiple specialized components, thereby reducing overall device complexity
