Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional product performance test methods are used, then test coverage is comprehensive, but test workload is high and test cost is high
Solution Approach 1:
The patent extracts and focuses on testing only the key parameters (specific heat capacity C, heat transfer coefficient K, energy efficiency ratio E, and mass m of heat storage material) that most significantly affect product performance. By taking out the essential parameters from the comprehensive test set, the method reduces test workload while maintaining adequate assessment quality.
Solution Approach 2:
The patent changes the testing approach by focusing on specific physical parameters (C, K, E, m) rather than conducting exhaustive performance tests. This parameter-based approach transforms the testing methodology from comprehensive but labor-intensive to targeted and efficient, resolving the contradiction between test coverage and workload.
2Reliability
If traditional product performance test methods are used, then test thoroughness is maintained, but test cost increases
Solution Approach 1:
The patent extracts the critical parameters that most influence product reliability and performance. By testing only these key parameters (specific heat capacity, heat transfer coefficient, energy efficiency ratio, and mass of heat storage material), the method maintains test thoroughness for the most important aspects while significantly reducing overall test cost.
Solution Approach 2:
The patent shifts from comprehensive performance testing to parameter-based testing, changing the fundamental approach to assessment. This parameter-focused methodology maintains reliability by measuring the most critical factors while reducing the resources required for testing.
3Quantity of substance
If existing test methods for thermal insulation devices are used, then test completeness is achieved, but scientific rigor is insufficient
Solution Approach 1:
The patent introduces a scientifically rigorous parameter-based testing framework that measures specific physical quantities (specific heat capacity C, heat transfer coefficient K, energy efficiency ratio E, and mass m). This approach enhances scientific rigor by using well-defined physical parameters with clear measurement standards, while maintaining test completeness through comprehensive parameter assessment.
Solution Approach 2:
The patent replaces traditional empirical testing methods with a physics-based measurement system that relies on fundamental thermodynamic parameters. This substitution introduces greaterscientific rigor by using established physical laws and measurable quantities rather than subjective or less precise evaluation methods.
