Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If technical gas is used as electrically insulating fluid, then insulation performance is ensured, but transportation complexity and environmental regulations increase
Solution Approach 1:
The system uses atmospheric air from the surrounding environment as the insulating fluid, eliminating the need for external technical gas supply and disposal infrastructure. The power transmission device serves itself by drawing air directly from its operational environment, thereby simplifying transportation and handling while maintaining insulation performance
Solution Approach 2:
Atmospheric air serves multiple functions: it provides electrical insulation, acts as a cooling medium, and eliminates the need for separate gas handling systems. This multi-functionality reduces the overall system complexity related to gas management while ensuring reliable insulation
2Quantity of substance
If technical gas is transported to and from the device, then insulation fluid supply is ensured, but transportation costs and environmental impact increase
Solution Approach 1:
The system draws insulating air directly from the surrounding environment, eliminating all transportation-related energy consumption and environmental impact. The device is self-sufficient by utilizing the ambient atmosphere as its fluid source, requiring no external supply chain for gas delivery
Solution Approach 2:
The system changes the source parameter of the insulating fluid from externally supplied technical gas to locally sourced atmospheric air. This parameter change eliminates transportation requirements and associated costs while ensuring continuous availability of insulation fluid
3Device complexity
If atmospheric air is used as insulating fluid, then transportation is simplified, but air quality and composition must be controlled
Solution Approach 1:
The system performs preliminary treatment of atmospheric air by filtering and drying it before introducing into the enclosed space. This preliminary action removes contaminants and moisture that could compromise insulation performance, ensuring air quality meets operational requirements
Solution Approach 2:
Filters and drying agents serve as intermediaries between the atmospheric air source and the enclosed insulating space. These intermediaries selectively remove unwanted components while allowing the beneficial properties of air to pass through, achieving both simplicity and quality control
4Quantity of substance
If the enclosed space is evacuated before filling, then fluid quality is improved, but processing time increases
Solution Approach 1:
The enclosed space is evacuated and prepared in advance before the power transmission device is assembled or before operation begins. This preliminary evacuation ensures that no contaminants are present when the atmospheric air is introduced, guaranteeing fluid quality without delaying operational setup
Solution Approach 2:
The evacuation process is performed continuously and efficiently using high-speed vacuum systems, minimizing the time the enclosed space remains empty. The transition from evacuation to filling is seamless, maintaining continuous useful action and reducing overall processing time
