Tilting Wheel Floor Cleaner for Corners and Furniture Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic cleaning machines are limited to moving in straight lines, making it difficult to reach corners and areas around furniture, and their cleaning units have a short service life due to fixed placement and wear, requiring frequent replacements.
Innovation Solution
An automatic cleaning device with a main body and operating unit featuring tilting wheels and a replaceable cleaning unit, allowing movement in all directions and altering contact area with the floor, powered by speed reducing units and a control unit for directional control, and equipped with a charging unit for extended operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning device moves in straight lines only, then the structure is simple, but it cannot reach corners and areas around furniture legs
Solution Approach 1:
The patent applies the dynamics principle by making the wheels tiltable relative to the main body. The wheels can rotate from a horizontal position (for straight-line movement) to a tilted position (for reaching corners and narrow spaces). This dynamic adjustment allows the cleaning device to adapt its movement capability between different cleaning scenarios, transitioning from simple straight-line motion to complex multi-directional navigation as needed.
2Reliability
If the cleaning unit is fixedly disposed on the machine, then the structure is stable, but the cleaning unit is easily worn out and has short service life
Solution Approach 1:
The patent applies segmentation by dividing the cleaning device into distinct modular components: the main body and the cleaning unit. The cleaning unit is made as a separate, detachable module that can be easily removed and replaced when worn. This modular segmentation allows the cleaning unit to be independently maintained or replaced without affecting the main device structure, thereby extending the overall service life of the cleaning machine.
3Productivity
If the cleaning unit is fixedly disposed, then the structure is simple, but frequent replacement is required increasing loss of time
Solution Approach 1:
The patent applies dynamics by enabling the cleaning unit to be dynamically adjusted and replaced. The tiltable wheel design allows the cleaning unit to be positioned optimally for different cleaning tasks, and when wear occurs, the same modular design that enables tilting also facilitates quick detachment and replacement, minimizing downtime and maintaining high productivity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effective cleaning of all floor corners and extends the device's service life by allowing directional movement and replaceable cleaning units, reducing the need for frequent part replacements and enhancing operational efficiency.
Implementation Method 1
Friction between the cleaning unit and a floor may cause the automatic cleaning device to move around

AI summary
An automatic cleaning device includes a main body and an operating unit. The operating unit is disposed on the lower side of the main body and includes several wheels. At least one of these wheels tilts downward with respect to the main body and the wheels may cause the automatic cleaning device to move around. In addition, with the aid of a piece of fabric, brush or dust removal paper attached to each wheel, the automatic cleaning device of the present invention can freely move around and clean up all corners of a flat floor.
