Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If numerical simulation is used to obtain icing data, then research efficiency is improved, but measurement precision and reliability are insufficient
Solution Approach 1:
The patent combines numerical simulation with physical model testing into an integrated verification system. The numerical simulation results are compared against and verified by physical test data, merging two different approaches to achieve both efficiency and accuracy.
Solution Approach 2:
The system uses physical test results as feedback to validate and refine the numerical simulation model. The comparison between simulation predictions and actual test measurements creates a feedback loop that improves the reliability of the simulation approach.
2Measurement precision
If physical simulation testing is conducted, then measurement precision is improved, but device complexity and test costs increase
Solution Approach 1:
The physical testing system is segmented into distinct functional modules: water droplet generation system, aerostat model mounting system, temperature control system, and data acquisition system. This modular segmentation reduces overall system complexity by making each component independent and manageable.
Solution Approach 2:
The patent introduces a standardized interface layer between the physical test apparatus and the numerical simulation model. This intermediary allows the two different systems to communicate and compare results without requiring direct complex integration.
3Reliability
If comprehensive test verification is implemented, then reliability of icing characteristics analysis is improved, but loss of time and resources increases
Solution Approach 1:
The numerical simulation is performed as a preliminary action before conducting physical tests. This allows potential issues to be identified and parameters to be optimized in advance, reducing the time required for actual physical experimentation and verification.
