Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If suction power is increased to improve cleaning effectiveness, then cleaning quality is improved, but power consumption increases and service duration decreases
Solution Approach 1:
The suction power is made dynamically adjustable based on real-time dirt level detection. The processing circuit automatically adjusts the suction power level according to the detected dirt level, allowing the system to use high power only when necessary (when dirt is detected) and low power when the surface is clean, thus resolving the contradiction between cleaning effectiveness and power consumption
Solution Approach 2:
The system implements a feedback mechanism where the optical sensor continuously detects the dirt level and provides information to the processing circuit, which then adjusts the suction power accordingly. This closed-loop control ensures that suction power is optimized based on actual cleaning needs, preventing both over-power consumption on clean surfaces and under-power on dirty surfaces
2Use of energy by moving object
If suction power is decreased to reduce power consumption, then service duration is extended, but cleaning quality deteriorates
Solution Approach 1:
The suction power operates dynamically at different levels based on detected dirt conditions. When the optical sensor detects a clean surface, the system switches to low power mode to conserve energy and extend service duration. When dirt is detected, the system automatically increases power to maintain cleaning effectiveness, thus resolving the contradiction between power consumption and cleaning quality
3Device complexity
If manual adjustment of suction power is required, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The system performs self-adjustment of suction power based on automatic dirt level detection. The optical sensor and processing circuit work together to automatically determine the appropriate suction power level without requiring user intervention. This eliminates the need for complex manual adjustment mechanisms while providing convenient automatic operation, resolving the contradiction between device complexity and ease of operation
