Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If suction force is increased to improve cleaning performance, then cleaning efficiency is improved, but battery consumption increases
Solution Approach 1:
The suction force is dynamically adjusted based on detected floor type. The controller increases suction force when soft floors are detected and decreases it on hard floors, allowing the system to optimize cleaning efficiency while minimizing battery consumption through adaptive parameter changes
Solution Approach 2:
The system changes the suction force parameter according to the detected floor state. By detecting whether the floor is soft or hard and adjusting the suction force accordingly, the system achieves optimal cleaning performance while reducing unnecessary energy consumption
2Device complexity
If floor state detection relies on single sensor type, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The system combines multiple detection methods including wheel load sensing, brush load sensing, and acceleration information into a unified floor state detection system. This multi-sensor approach improves measurement precision by cross-validating data from different sources while managing complexity through integrated processing
