Solution Overview
Problem
Cleaning robots face poor cleaning effectiveness on uneven floors due to their cleaning components failing to fit the surface properly, leading to inadequate cleaning performance.
Innovation Solution
A turntable structure with a cleaning turntable, an adjusting component, and a pressure unit that allows the cleaning piece to slide relative to the turntable, applying a vertical downward force and adjusting to fit uneven surfaces, ensuring the cleaning piece maintains contact with the floor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning robot uses a fixed cleaning component structure, then the structure is simple, but the cleaning component cannot fit uneven floors, resulting in poor cleaning effect
Solution Approach 1:
The cleaning turntable is designed to rotate around a vertical axis, allowing the cleaning piece to dynamically adjust its position and orientation in response to uneven floor surfaces. The rotating mechanism enables the cleaning component to adapt to various floor conditions while maintaining contact, transforming a static structure into a dynamic one that can respond to environmental variations.
Solution Approach 2:
The cleaning assembly is segmented into a rotating turntable component and a fixed support structure. This segmentation allows the cleaning turntable to independently rotate and adjust, while the support structure remains stable. The modular design enables the cleaning piece to adapt to uneven floors without compromising the overall structural integrity.
2Reliability
If the cleaning component is made adjustable to fit uneven floors, then cleaning effectiveness improves, but the device complexity increases
Solution Approach 1:
The rotating turntable structure enables the cleaning piece to automatically adjust its position through rotation, responding to uneven floor surfaces without requiring complex external adjustment mechanisms. The system uses the robot's movement and floor contact forces to naturally position the cleaning piece, reducing the need for additional actuators or control systems.
Solution Approach 2:
The invention changes the positional parameters of the cleaning piece through rotation of the turntable. By varying the angular position of the cleaning piece around the vertical axis, the system adapts to different floor conditions, achieving reliable cleaning effectiveness through parameter variation rather than structural complexity.
3Reliability
If the cleaning piece maintains constant contact with the floor, then cleaning effectiveness improves, but vibration from unbalanced components increases
Solution Approach 1:
The rotating turntable provides dynamic adjustment capability that allows the cleaning piece to maintain optimal contact with the floor while accommodating variations in floor surface. This dynamic positioning helps distribute contact forces more evenly, reducing vibration caused by unbalanced components during operation.
Solution Approach 2:
The vertical rotation axis of the turntable is designed to align with the gravitational direction, creating an equipotential configuration where the rotating cleaning piece maintains consistent contact pressure with the floor throughout its rotation. This alignment minimizes centrifugal forces and reduces vibration from unbalanced components.
