Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional automatic cleaners perform cleaning operations without liquid/colloid detection capability, then the cleaner can operate continuously, but it causes harmful effects by attempting to clean liquids and colloids which it cannot handle
Solution Approach 1:
The system performs preliminary detection of liquids and colloids using optical sensors before the cleaning operation begins. The processing circuit analyzes optical data to identify the presence of liquids or colloids in advance, allowing the cleaner to adjust its operation beforehand and avoid harmful cleaning attempts
Solution Approach 2:
The system continuously monitors the cleaning environment using optical sensors and provides feedback to the control circuit. Based on the detected optical data indicating liquid or colloid presence, the system adjusts its cleaning operations in real-time to prevent harmful effects while maintaining productivity
2Ease of manufacture
If the light emitting device emits light perpendicular to the surface (0° angle), then the detection setup is simple, but it cannot effectively detect liquids or colloids
Solution Approach 1:
The patent changes the emission angle parameter of the light emitting device from the conventional perpendicular (0°) to an oblique angle (45°-60°). This parameter change enables the optical sensor to detect light reflected from liquid or colloid surfaces, which have different reflective properties compared to solid surfaces, thereby achieving effective detection
