Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional automatic cleaners perform clean action without liquid/colloid detection capability, then the cleaner can operate continuously, but the cleaning effectiveness deteriorates and environmental conditions worsen
Solution Approach 1:
The system performs preliminary detection of liquid or colloid on the surface before initiating cleaning operations. The optical sensor detects optical data and the processing circuit determines the presence of liquid/colloid in advance, allowing the cleaner to avoid or adjust its cleaning action accordingly, preventing harmful effects before they occur
Solution Approach 2:
The patent introduces an intermediary detection system (optical sensor and processing circuit) between the cleaner and the surface. This intermediary detects liquid/colloid presence and provides information to control the cleaning operation, acting as a mediator that prevents direct harmful interaction between the cleaner and liquid/colloid
2Measurement precision
If the automatic cleaner is equipped with light emitting device and optical sensor for liquid detection, then detection accuracy improves, but device complexity increases
Solution Approach 1:
The light emitting device and optical sensor serve multiple functions: they detect liquid/colloid presence, determine liquid/colloid location for navigation avoidance, and can potentially assist in cleaning operations. This multi-functionality justifies the added complexity by providing comprehensive detection and navigation capabilities
