Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hand-push scrubbers are limited to monodirectional cleaning and cannot enter low spaces such as under tables or beds due to non-rotating squeegees, resulting in poor effectiveness and a restricted application range.
Innovation Solution
A hand-push scrubber design featuring a rotating squeegee assembly with a 180-degree rotation capability, enabled by a hub motor system and a swinging mechanism, allowing for multi-directional cleaning and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the squeegee is made fixed and non-rotating, then the structure is simple and stable, but the scrubber cannot enter low spaces and is limited to monodirectional cleaning
Solution Approach 1:
The squeegee assembly is transformed from a fixed structure to a dynamic one, enabling it to rotate 180 degrees around a transverse axis. The squeegee bracket is designed with rotational freedom around the mounting sleeve, allowing the squeegee to adapt its orientation based on cleaning needs while maintaining structural simplicity through controlled degrees of freedom
2Adaptability or versatility
If the squeegee is made rotatable to enable multi-directional cleaning, then the application range is expanded, but the structural complexity increases
Solution Approach 1:
The squeegee assembly is segmented into multiple independent components: squeegee, squeegee bracket, mounting sleeve, and connecting sleeve. Each component has a specific function and can move or rotate independently, reducing the overall structural complexity while enabling multi-directional cleaning capability
Solution Approach 2:
The components are nested within each other in a compact arrangement: the squeegee is mounted on the squeegee bracket, which rotates on the mounting sleeve, which is connected to the connecting sleeve. This nested structure minimizes space requirements and reduces overall device complexity while maintaining rotational functionality
3Adaptability or versatility
If the scrubber enters low spaces with limited headroom, then the cleaning coverage is improved, but the squeegee cannot perform normal cleaning due to inability to rotate
Solution Approach 1:
The squeegee assembly incorporates dynamic rotational capability around a transverse axis, allowing it to rotate 180 degrees to adapt to different cleaning scenarios. This dynamic design ensures that the squeegee can maintain effective contact with the ground surface regardless of the scrubber's orientation or the space constraints, thereby maintaining cleaning reliability in low spaces
