Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single reference direction is set for the entire region of interest, then the analysis method is simple, but the analysis accuracy deteriorates when the region has a distorted shape
Solution Approach 1:
The patent divides the region of interest into multiple subregions and sets a reference direction for each subregion individually. This segmentation allows the analysis to adapt to local variations in the distorted region while maintaining a systematic approach, resolving the contradiction between simplicity and accuracy.
Solution Approach 2:
The patent applies different reference directions to different subregions based on their local characteristics. Each subregion receives a tailored reference direction that matches its specific orientation, enabling accurate flow state analysis in distorted regions without requiring a completely complex overall system.
2Measurement precision
If the region of interest is divided into multiple subregions with individual reference directions, then the analysis accuracy improves, but the device complexity increases
Solution Approach 1:
By segmenting the region of interest into subregions, the patent achieves local accuracy without making the entire system overly complex. Each subregion can be processed independently with its own reference direction, allowing for modular implementation that balances accuracy and complexity.
Solution Approach 2:
The patent dynamically determines reference directions for each subregion based on the local geometry and characteristics of that subregion. This dynamic adaptation allows the system to maintain accuracy in distorted regions while avoiding the need for predetermined complex configurations.
3Ease of operation
If a fixed reference direction is used, then the analysis process is straightforward, but it cannot accurately determine flow state in distorted regions
Solution Approach 1:
The patent maintains operational simplicity by using a systematic segmentation approach where each subregion follows the same analysis procedure with its own reference direction. This preserves ease of operation while improving reliability through local adaptation to distorted geometries.
Solution Approach 2:
The patent applies local quality by determining reference directions that match the specific characteristics of each subregion. This allows the analysis process to remain straightforward while achieving reliable results in distorted regions through localized reference direction optimization.
