Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional grinder is used to grind coffee beans, then the grinding process is simple and fast, but the particle size distribution is inconsistent and lacks variety
Solution Approach 1:
The grinder's particle size settings are made dynamically adjustable through a control device that can change grinding parameters during operation. The system allows switching between multiple predetermined particle size distributions and enables real-time adjustment based on user preferences, transforming a static grinder into a dynamic system that adapts to different grinding requirements.
Solution Approach 2:
The invention changes the grinding parameters (particle size distribution, grinding speed, feed rate) to achieve diverse and consistent particle sizes. The control device manages multiple parameters including the rotation speeds of grinding wheels, the feed rate of coffee beans, and the gap between grinding surfaces, allowing precise control over the final particle size distribution.
2Productivity
If multiple particle sizes are ground simultaneously, then productivity is high, but flavor quality deteriorates due to mixing
Solution Approach 1:
The grinding process is segmented into multiple independent streams, each producing a specific particle size distribution. The control device manages separate grinding zones or sequentially operates different grinding configurations to produce uniform particles, then combines them in controlled proportions to achieve the desired final distribution while maintaining flavor quality.
Solution Approach 2:
The system uses periodic action by sequentially grinding different particle sizes in separate cycles rather than simultaneously. The control device switches between different grinding configurations or activates different grinding wheels in sequence, ensuring each particle size is produced under optimized conditions before combining the results.
3Adaptability or versatility
If manual ordering and parameter setting is required, then customization is possible, but operation convenience is reduced
Solution Approach 1:
The system provides self-service functionality by allowing users to automatically input order information (such as customer preferences or order numbers) and the control device automatically selects and applies the appropriate particle size distribution settings. The grinder operates autonomously based on pre-programmed parameters, eliminating the need for manual adjustment while maintaining high customization capability.
Solution Approach 2:
The control device incorporates feedback mechanisms to receive order information and automatically adjust grinding parameters accordingly. The system monitors the grinding process and makes real-time adjustments to maintain the desired particle size distribution based on the selected order profile, ensuring consistent quality without manual intervention.
