Cleaning assembly and cleaning robot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning robots lack adaptability due to their cleaning modules being fixed and unable to be lifted or lowered relative to the main body, limiting their ability to effectively clean various surfaces.
Innovation Solution
A cleaning assembly with a rotating shaft and gear part connected to a rotation transmission mechanism, allowing the cleaning module to be lifted or lowered axially, driven by a rotation drive motor and transmission mechanism, which includes a lifting mechanism to adjust the lifting angle and maintain the cleaning position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning module is fixed relative to the main body, then the structure is simple, but the adaptability to different surfaces is poor
Solution Approach 1:
The cleaning module is designed to be dynamically adjustable relative to the main body through a lifting mechanism. The rotating shaft can move axially to lift or lower the cleaning module, transforming it from a static fixed structure to a dynamic adjustable one, thereby improving adaptability to different surface conditions while maintaining reasonable structural complexity through standardized mechanical components
2Manufacturing precision
If the rotating shaft has high-precision polygonal cross section, then the meshing precision is improved, but the manufacturing cost and complexity increase
Solution Approach 1:
The patent replaces the expensive high-precision polygonal cross section rotating shaft with a simpler cylindrical shaft combined with a gear part. This substitution uses more manufacturable, lower-cost components (standard cylindrical shafts and gears) to achieve the same functional outcome of precise meshing, thereby reducing manufacturing precision requirements while maintaining operational effectiveness

Function Achieved in This Case
Enhances the adaptability of the cleaning robot by allowing the cleaning module to adjust its position relative to the surface, reducing processing costs and complexity by eliminating the need for high-precision polygonal cross sections in the rotating shaft.
Implementation Method 1
the gear part is connected with the rotation transmission mechanism to rotate the rotating shaft; the rotating shaft is configured to drive the gear part to move axially relative to the rotation transmission mechanism
