Bidirectional cleaning machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning machines have unsatisfactory cleaning effects due to unidirectional rotation of the cleaning disk and fixed handle angles, making them labor-intensive and inconvenient to use.
Innovation Solution
A bidirectional cleaning machine with an inner and outer cleaning disk rotating in opposite directions and an adjustable handle angle, achieved through a mechanism involving gears, clamping rings, and a power mechanism for synchronized rotation and angle adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning disk rotates in only one direction, then the structure is simple, but the cleaning effect on stubborn stains is moderate and unsatisfactory
Solution Approach 1:
The cleaning mechanism transitions from static unidirectional rotation to dynamic bidirectional rotation. The power mechanism enables the cleaning disk to alternate between clockwise and counter-clockwise rotation, adapting the cleaning action to different stain types and surfaces, thereby improving cleaning effectiveness without excessive complexity increase
Solution Approach 2:
The cleaning disk employs periodic bidirectional rotation where the power mechanism drives alternating rotation cycles in opposite directions. This periodic reversal creates enhanced mechanical action on stubborn stains during the return stroke, improving overall cleaning performance while maintaining a relatively simple mechanical structure through rhythmic motion patterns
2Ease of operation
If the handle is fixedly connected to the cleaning machine, then the structure is stable, but the angle cannot be adjusted making it inconvenient to use
Solution Approach 1:
The handle connection transitions from a fixed static joint to a dynamic adjustable mechanism. Users can rotate the handle to different angles and lock it in position using the button-operated clamping system, providing operational flexibility while maintaining structural stability during use through the locking mechanism
Solution Approach 2:
The handle connection is segmented into movable and fixed states through the clamping mechanism. The button-operated system divides the connection into adjustable segments that can be repositioned independently, allowing angle adjustment without compromising the overall structural integrity when locked in place
