Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the cleaning robot uses high cleaning strength parameters, then cleaning effectiveness is improved, but obstacles are easily entangled causing safety issues

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidcleaning process safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic adjustment of cleaning parameters based on real-time obstacle detection. The cleaning robot switches between first cleaning parameters (high cleaning strength) and second cleaning parameters (low cleaning strength) depending on whether obstacles are detected, making the cleaning strength adaptable rather than fixed. This resolves the contradiction by allowing high cleaning effectiveness when safe and low cleaning strength when obstacles are present.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes cleaning parameters (such as brush rotation speed, suction force) based on detection results. When obstacles are detected, the system transitions from first cleaning parameters with high cleaning strength to second cleaning parameters with low cleaning strength, preventing entanglement while maintaining cleaning effectiveness when appropriate.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the cleaning robot adjusts cleaning parameters frequently to avoid obstacles, then safety is improved, but cleaning efficiency decreases

Engineering Contradiction:
Improvecleaning process safetyVSAvoidcleaning efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system dynamically adjusts cleaning parameters only when necessary - specifically when obstacles are detected or when transitioning between clean and dirty areas. This dynamic approach maintains safety by adjusting parameters at critical moments while preserving cleaning efficiency during normal operation without unnecessary adjustments.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses obstacle detection and area detection as feedback mechanisms to trigger parameter adjustments only when conditions warrant them. The system continuously monitors the environment and adjusts cleaning parameters based on feedback from sensors, ensuring safety improvements are made only when actually needed rather than through frequent unnecessary adjustments.

Inventive Principle:
Principle #23Feedback

AI summary

A cleaning method and apparatus for a cleaning robot, a medium, and a device. The method comprises: performing obstacle detection to obtain a detection result; at least on the basis of the detection result and current cleaning parameters, determining a preset adjustment condition which is met by a cleaning robot and used for adjusting the cleaning parameters; adjusting the cleaning parameters by using an adjustment strategy corresponding to the preset adjustment condition so as to adjust the current cleaning parameters from predetermined first cleaning parameters to second cleaning parameters corresponding to a target obstacle in the detection result, or to adjust the current cleaning parameters from the second cleaning parameters corresponding to the target obstacle to the predetermined first cleaning parameters, wherein the cleaning intensity corresponding to the first cleaning parameters is higher than the cleaning intensity corresponding to the second cleaning parameters; and performing cleaning on the basis of the current cleaning parameters.
