Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the automatic cleaning device operates at normal power level, then cleaning efficiency is maintained, but noise level increases and disturbs user activities
Solution Approach 1:
The patent implements dynamic mode switching between normal mode and mute mode based on real-time detection of user presence. The system adjusts operating parameters (power level, cleaning path) dynamically when a user is detected within the preset distance, and returns to normal operation when the user moves away, thus adapting the noise output to the actual usage context.
Solution Approach 2:
The patent changes key operating parameters when switching to mute mode: reducing power level to a preset value and generating a modified mute path with repeated combinations of original paths. These parameter changes directly reduce noise generation while the system monitors and responds to user proximity conditions.
2Object-generated harmful factors
If the power level is reduced to decrease noise, then noise pollution is reduced, but cleaning effectiveness may be compromised
Solution Approach 1:
The patent employs periodic/repeated cleaning actions by generating a mute path that consists of repeated combinations of the original cleaning paths. This allows the cleaning device to perform multiple passes over the same area at reduced power, ensuring that cleaning effectiveness is maintained despite the lower operating power level during mute mode.
Solution Approach 2:
The system performs preliminary detection of user presence before initiating mute mode operations. By detecting user proximity in advance and switching to mute mode proactively, the system can plan appropriate cleaning paths and power adjustments beforehand, ensuring cleaning effectiveness is not compromised during the noise-reduced operation.
3Area of stationary object
If a mute path is generated with repeated combinations of original paths, then cleaning coverage is maintained, but operation time increases
Solution Approach 1:
The patent implements periodic cleaning actions by repeating combinations of original paths in mute mode. The system performs multiple passes over cleaning areas to ensure complete coverage when operating at reduced power, accepting increased operation time as a necessary trade-off for maintaining effective cleaning at lower noise levels.
Solution Approach 2:
The system dynamically adjusts path planning based on the cleaning mode. In mute mode, it generates extended paths with repeated combinations to ensure coverage; in normal mode, it uses standard efficient paths. This dynamic path adaptation optimizes the balance between coverage and time based on current operational requirements.
