Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual mixing operation is used, then human labor can perform the mixing, but harm may be brought to human bodies when corrosive or poisonous liquids are mixed
Solution Approach 1:
The mixing valve enables self-service operation through automated control mechanisms. The valve cores and impellers work automatically to mix solutions without human intervention, eliminating the need for operators to manually handle corrosive or poisonous liquids while maintaining mixing functionality
Solution Approach 2:
The patent replaces manual mechanical mixing with an automated valve system. The mixing valve uses valve cores, impellers, and flow control mechanisms to automatically mix solutions, substituting the manual mechanical operation with a controlled mechanical system that eliminates direct human contact with hazardous materials
2Quantity of substance
If large-volume solutions are mixed manually in advance, then solutions can be conveyed to production lines, but it takes a long time to fully mix the solutions, lowering production efficiency
Solution Approach 1:
The mixing valve employs dynamic flow control through rotatable valve cores and adjustable impellers. The system can dynamically adjust flow rates and mixing intensity based on the volume of solutions being processed, enabling efficient mixing of large volumes by optimizing fluid dynamics and circulation patterns
Solution Approach 2:
The mixing valve enables continuous mixing operation through its design that allows solutions to be continuously fed, mixed, and discharged. The valve cores and impellers maintain continuous circulation and mixing action, eliminating the batch processing delays associated with manual mixing and enabling uninterrupted production flow
3Ease of operation
If conventional mixing valves control flow rate by operation handle, then mixing operation can be performed, but solution volumes must be determined in advance based on blending ratio, reducing flexibility
Solution Approach 1:
The valve cores are designed to be rotatable and adjustable, allowing dynamic control of flow rates and mixing ratios. The operation handle connects to the valve cores through a transmission mechanism that enables continuous adjustment of opening degrees, providing flexible control adaptability for different solution volumes and blending ratios without requiring predetermined settings
4Productivity
If conventional mixing valves mix two solutions without considering mixing time and volume, then mixing can be performed quickly, but two large-volume solutions are mixed for a short time, affecting product quality
Solution Approach 1:
The impellers are designed with adjustable parameters including rotation speed and immersion depth. The system can dynamically adjust mixing intensity and duration based on solution volume and desired quality standards. The valve cores control flow rates to ensure adequate mixing time while maintaining productivity through optimized fluid circulation
Solution Approach 2:
The mixing valve enables parameter changes in the mixing process including flow rate, mixing time, and impeller speed. By adjusting these parameters, the system can optimize the balance between mixing speed and product quality, ensuring thorough mixing of large-volume solutions while maintaining high productivity through controlled parameter variation
