Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional conveying devices are used to feed substances into the mixing device, then the substance can be conveyed to the mixing device, but the amounts of substances added cannot be precisely controlled
Solution Approach 1:
The patent implements feedback control by connecting a weight meter to the buffer member to continuously monitor the weight of stored substance. The control assembly receives weight information from the weight meter and automatically adjusts the back pressure valve to control the conveying rate, ensuring precise control of the weight of conveyed substance without requiring complex manual intervention
Solution Approach 2:
The system achieves self-regulating conveying through the automatic interaction between the weight meter, control assembly, and back pressure valve. The weight meter automatically detects weight changes, the control assembly processes this information, and the back pressure valve automatically adjusts the conveying rate, creating a self-service control loop that maintains precision without external intervention
2Productivity
If the conveying pipeline is continuously open to allow substance flow, then the conveying efficiency is high, but the precision of controlling the weight of conveyed substance deteriorates
Solution Approach 1:
The back pressure valve dynamically adjusts the conveying rate based on real-time weight feedback from the weight meter. The valve transitions between different opening states to control the substance flow rate, achieving both efficient conveying and precise weight control through dynamic adjustment rather than static open/closed states
Solution Approach 2:
The system controls the conveying process by changing the pressure parameter through the back pressure valve. By adjusting the back pressure, the conveying rate is controlled to match the required weight addition rate, maintaining both productivity and precision through parameter optimization
