Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If image-based techniques are used to analyze coffee particle size distribution, then the method is simple and non-destructive, but the analysis accuracy is insufficient
Solution Approach 1:
The patent applies mechanical vibration through a vibration source that drives the coffee particles to vibrate at least twice during the imaging process. This vibration disperses the coffee particles, preventing overlap and aggregation, thereby significantly improving the accuracy of particle size measurement while maintaining the simplicity of the image-based analysis method.
2Measurement precision
If multiple images are captured at different vibration modes, then particle dispersion improves and analysis accuracy increases, but the complexity of the device increases
Solution Approach 1:
The patent employs a vibration source capable of generating at least two different vibration modes with different frequencies. By capturing images during different vibration modes, the system achieves better particle dispersion and measurement accuracy. The vibration source is integrated into the device, adding minimal complexity while significantly improving measurement quality.
3Stability of the object's composition
If vibration is applied to disperse coffee particles during imaging, then particle distribution uniformity improves, but the time required for analysis increases
Solution Approach 1:
The patent utilizes periodic vibration action where the vibration source operates in cycles with different frequencies. The system captures images during these periodic vibration cycles, achieving uniform particle distribution. The periodic nature of the vibration allows for efficient data collection within a limited time frame, balancing distribution uniformity with analysis speed.
