Adhesive Roller Cleaning Tool with Automatic Take-Up Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adhesive roller-type cleaning tools require users to manually rotate a take-up unit to replace the adhesive sheet when it becomes covered with hair and lint, leading to inconvenient interruptions in cleaning and potential unintentional withdrawal of the adhesive sheet from the floor.
Innovation Solution
The adhesive roller-type cleaning tool incorporates a rotation transmission unit that synchronizes forward and backward rotations of the adhesive roller and take-up units, allowing seamless winding of the adhesive sheet without manual intervention and preventing unintentional withdrawal by engaging and disengaging the rotation transmission unit based on the tool's position relative to the contact surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a take-up unit is provided to wind up used adhesive sheet, then sanitation is improved by preventing direct hand contact with hair and lint, but device complexity increases due to additional components
Solution Approach 1:
The take-up unit is nested within the case unit, with the adhesive roller unit and take-up unit both rotatably installed inside the same housing. This integration allows the take-up function to be provided without significantly increasing overall device complexity, as the components share the same structural space and mounting framework.
2Object-affected harmful factors
If the take-up unit is manually rotated to take up used adhesive sheet, then sanitation is improved, but productivity decreases due to interruptions in cleaning work
Solution Approach 1:
The system transitions from a static manual operation to a dynamic automatic operation. The adhesive roller unit and take-up unit are connected through a rotation transmission unit that enables automatic rotation of the take-up unit based on the rotation of the adhesive roller unit, allowing continuous operation without manual intervention and maintaining high productivity.
Solution Approach 2:
The take-up unit performs the function of winding up used adhesive sheet automatically through the rotation transmission mechanism, without requiring external manual operation. The system serves itself by converting the rotational motion from the adhesive roller unit to automatically advance and wind the adhesive sheet, eliminating the need for users to stop and manually replace sheets.
3Ease of operation
If the adhesive roller unit is free to rotate backward, then ease of operation is improved by allowing easy retrieval, but reliability decreases due to unintentional withdrawal of adhesive sheet from the floor
Solution Approach 1:
The rotation transmission unit dynamically engages and disengages based on the direction of rotation. During forward rotation (cleaning operation), the units are engaged to synchronize motion. During backward rotation (retrieval operation), the engagement is released to allow free rotation of the adhesive roller unit, preventing unintentional withdrawal while maintaining ease of operation.
Solution Approach 2:
The system uses the rotational direction of the adhesive roller unit as feedback to control the engagement state of the rotation transmission unit. When rotation detects forward motion, engagement is activated; when backward motion is detected, engagement is deactivated. This feedback mechanism ensures reliable operation during cleaning while allowing easy retrieval when needed.

AI summary
A rotatably installed adhesive roller unit and a take-up unit to wind up the adhesive sheet after being drawn out of the adhesive roller unit and having lint adhered thereon. The take-up unit is installed to be configured to rotate forward and backward synchronized through a rotation transmission unit with forward and backward rotation of the adhesive roller unit. The adhesive roller unit engages the rotation transmission unit when pressed onto a contact surface and moved forward. The adhesive roller unit is energized to release the engagement with the rotation transmission unit when moved backward and separated from the contact surface. A rotation inhibiting mechanism is provided to inhibit the rotation of both the adhesive roller unit and the take-up unit when the adhesive roller unit separates from the contact surface.
