Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mixing methods are used without quality measurement, then the preparation process is simple, but the quality of drinking water fluctuates significantly
Solution Approach 1:
The refractometer measures the refractive index of the liquid component, and this measurement is fed back to the control system which automatically calculates and adjusts the quantity of drinking water components to be added. This closed-loop feedback mechanism ensures consistent dry matter content despite variations in raw material quality.
Solution Approach 2:
The patent replaces manual quality assessment and dosage adjustment with an automated optical measurement system (refractometer) and electronic control system. The refractometer provides objective, quantitative measurement of liquid component quality, substituting subjective human judgment and manual mechanical dosing.
2Measurement precision
If manual quality assessment is used, then the process is simple to operate, but the precision of quality control is insufficient
Solution Approach 1:
The refractometer and control system perform quality measurement and calculation automatically without requiring operator expertise. The system self-calibrates and self-adjusts based on measurements, eliminating the need for manual quality assessment skills while maintaining high measurement precision.
Solution Approach 2:
The patent transforms the quality assessment from subjective manual evaluation to objective measurement of the refractive index parameter. By measuring this physical parameter and using it to calculate the required dry matter content, the system achieves precise quality control through quantifiable data rather than subjective judgment.
3Manufacturing precision
If dosage is adjusted based on visual inspection, then the process is quick, but the manufacturing precision of dry matter content is poor
Solution Approach 1:
The refractometer measures the refractive index of the liquid component before mixing occurs, and the control system pre-calculates the exact quantity of drinking water components needed to achieve the target dry matter content. This preliminary measurement and calculation prevent the need for time-consuming adjustments after mixing.
Solution Approach 2:
The patent replaces time-consuming manual quality assessment and iterative dosage adjustment with rapid optical measurement and automated electronic calculation. The refractometer provides immediate refractive index values, and the control system instantly computes the required component quantities, significantly reducing preparation time while improving precision.
