Cleaning robot, cleaning system, and cleaning method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional single household cleaning robots cannot effectively clean both hard and soft surfaces, such as carpets, due to their limited adaptability, which restricts their functionality and user convenience.
Innovation Solution
A cleaning robot equipped with a moving unit, a mopping unit with a rising mopping head, and a control unit that automatically switches between sweeping and mopping modes, allowing the robot to adapt to different surfaces by controlling the mopping head's height and mode selection based on surface type, ensuring effective cleaning of both hard and soft materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning robot uses a fixed mopping head for hard ground cleaning, then mopping effectiveness is improved, but adaptability to soft surfaces deteriorates
Solution Approach 1:
The mopping head is designed with dynamic height adjustment capability, allowing it to move between a lowered position for effective mopping on hard surfaces and a raised position to prevent damage to soft surfaces like carpets. This dynamic positioning resolves the contradiction by adapting the mopping head's contact with the surface based on the detected surface type.
Solution Approach 2:
The system changes the operational parameter of the mopping head by adjusting its height position. When transitioning from hard ground to soft surface detection, the control unit commands the mopping head to rise to a predetermined height, changing its physical state from contact to non-contact mode, thereby adapting to different surface requirements.
2Adaptability or versatility
If the cleaning robot raises the mopping head by a small height, then adaptability to soft surfaces is improved, but cleaning effectiveness on hard grounds deteriorates
Solution Approach 1:
The mopping head employs dynamic height adjustment with distinct position states: a lowered position for optimal mopping contact on hard surfaces and a raised position for soft surface protection. This dynamic switching ensures that when on hard grounds, the mopping head maintains full cleaning effectiveness, while on soft surfaces, it raises sufficiently to prevent damage.
3Ease of operation
If the cleaning robot uses a fixed cleaning mode, then operational simplicity is improved, but functionality for different surfaces deteriorates
Solution Approach 1:
The cleaning robot autonomously detects surface types using sensors and automatically switches between cleaning modes (mopping mode for hard surfaces, sweeping mode for soft surfaces) without user intervention. This self-service capability maintains operational simplicity for the user while providing advanced adaptability to different surface types.
Solution Approach 2:
The system incorporates sensor feedback mechanisms that detect surface characteristics in real-time and feed this information to the control unit, which then automatically adjusts the cleaning mode and mopping head position accordingly. This feedback loop enables the robot to adapt its functionality to different surfaces while keeping the operation simple for the user.
