Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual recognition of states is used, then user control is possible, but error susceptibility increases and operation convenience decreases
Solution Approach 1:
The coffee machine performs self-detection of its own operational states using integrated sensors and image processing capabilities. The system automatically monitors water levels, bean hopper status, and brewing conditions without requiring manual user intervention, thereby improving both reliability and operational convenience simultaneously.
Solution Approach 2:
Manual mechanical inspection and sensor-based detection are replaced with image processing technology using cameras and deep learning algorithms. The system captures images of the brewing process and uses AI models to accurately determine operational states, eliminating human error while maintaining ease of operation.
2Extent of automation
If classic sensors are used for state detection, then automated detection is achieved, but measurement precision is insufficient and cost increases
Solution Approach 1:
Traditional mechanical and electrical sensors are replaced with optical image processing systems. Cameras capture visual information about water levels, bean quantity, and brewing states, which are then analyzed by deep learning models to achieve high-precision detection that surpasses conventional sensor capabilities.
Solution Approach 2:
Instead of using physical sensors that directly contact or measure physical quantities, the system creates optical copies (images) of the operational states. These visual copies are then processed by AI algorithms to extract precise measurement information about water levels, ingredient quantities, and brewing conditions.
3Adaptability or versatility
If multiple individual sensors are used for different states, then comprehensive monitoring is achieved, but device complexity and cost increase
Solution Approach 1:
A single image processing system with deep learning capabilities performs multiple detection functions simultaneously. The same camera and AI model detect water levels, bean hopper status, brewing process states, and container positions, replacing what would otherwise require multiple specialized sensors and reducing overall system complexity.
Solution Approach 2:
Multiple detection functions that would traditionally require separate sensors are merged into a single integrated image processing system. The camera captures comprehensive visual information about all components, and the deep learning model simultaneously analyzes multiple aspects of the brewing system state from these images.
