Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an additional adjustment part consisting of a small deflector is added to the meter, then the measurement accuracy can be adjusted, but the device complexity increases and manufacturing costs increase
Solution Approach 1:
The patent combines the adjustment function directly into the existing turbine structure by making the turbine blades themselves adjustable, rather than adding a separate deflector component. This merging of functions reduces device complexity while maintaining the ability to adjust measurement accuracy across different flow rates.
2Measurement precision
If a small deflector is added for adjustment, then measurement calibration is possible, but the ease of operation deteriorates because the part is not easily accessible and difficult to handle
Solution Approach 1:
The patent implements a dynamic adjustment mechanism where the turbine blades can be easily repositioned between fixed angular positions. This allows operators to quickly adjust the meter for different flow rates without complex manual manipulation, significantly improving ease of operation while maintaining calibration capability.
3Device complexity
If a deflector with small dimensions is used, then the structural constraints are satisfied, but the effect on fluid flow is reduced, providing limited room for manoeuvre during adjustment
Solution Approach 1:
The patent applies local quality by varying the angle of individual turbine blades independently, allowing each blade to be optimized for specific flow rate ranges. This enables a wide adjustment range and provides operators with fine-grained control over the meter's characteristics for different operating conditions.
