Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If design margin is increased to ensure safety in high voltage vacuum insulation, then safety reliability is improved, but equipment volume and raw material consumption increase significantly
Solution Approach 1:
The patent applies parameter changes by systematically varying the vacuum degree (from 10^-1 to 10^-6 Pa), voltage levels (from 10 kV to 1 MV), and insulation material properties to establish quantitative relationships between these parameters and insulation performance. This enables precise determination of minimum safe design margins without excessive conservatism, thereby reducing equipment volume while maintaining safety.
Solution Approach 2:
The patent implements feedback mechanisms through real-time monitoring of vacuum degree, voltage, current, and temperature during testing. This feedback enables dynamic adjustment of test conditions and provides data for optimizing design margins based on actual performance rather than static conservative estimates, reducing unnecessary material usage while ensuring safety.
2Volume of stationary object
If design margin is reduced to optimize equipment size, then equipment volume and raw material consumption are reduced, but safety reliability may be compromised due to insufficient design margin
Solution Approach 1:
The patent uses systematic parameter changes to identify the minimum vacuum degree and voltage thresholds that maintain safe operation. By establishing precise quantitative relationships between parameters, the patent enables optimization of equipment size while ensuring safety through scientifically determined minimum margins rather than arbitrary reductions.
Solution Approach 2:
The patent applies partial action by conducting tests at specific critical vacuum levels and voltage points rather than continuous monitoring at all possible conditions. This enables identification of minimum safe margins with reduced testing resources while maintaining safety, avoiding excessive conservatism in design.
3Productivity
If estimation and simulation methods are used for high voltage vacuum insulation design, then design process efficiency is improved, but measurement precision and reliability of insulation performance evaluation deteriorate due to lack of direct reference standards
Solution Approach 1:
The patent creates a physical test platform that replicates high voltage vacuum insulation conditions, providing empirical data that validates and calibrates estimation and simulation methods. This copying of real-world conditions into controlled test environments enables accurate reference standards while maintaining design efficiency through the use of validated models for routine designs.
Solution Approach 2:
The patent develops a universal test platform capable of testing various insulation materials and configurations under different vacuum and voltage conditions. This multi-functional platform generates comprehensive reference data that can be applied across multiple design scenarios, improving both design efficiency and measurement precision through standardized empirical validation.
