Dual-Roller Adhesive Sheet Transfer for Jam-Free Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive cleaning systems using single-sided adhesive sheets have limited multi-use capabilities and often suffer from misalignment and jamming issues when using a pair of rollers, which restricts the effective transfer and reuse of adhesive sheets.
Innovation Solution
A novel adhesive cleaning system featuring a cleaning unit with two rollers and a double-sided adhesive sheet, where the adhesive sheet can be transferred diagonally between rollers, allowing for proper alignment and separation of the release liner, enabling multiple uses by alternating the exposure of adhesive layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single roller with a single-sided adhesive sheet is used, then the device structure is simple, but the adhesive sheet can only be used once and must be continually cleaned or replaced
Solution Approach 1:
The adhesive sheet is divided into two functional sides: a first adhesive layer for picking up debris and a second adhesive layer for releasing debris. This segmentation allows the sheet to perform different functions on each side, enabling it to be used multiple times by flipping it over when one side becomes saturated.
Solution Approach 2:
The adhesive sheet is designed with dual functionality - the first adhesive layer captures debris while the second adhesive layer releases it. This multi-functionality allows a single adhesive sheet to complete multiple cleaning cycles without replacement, extending its productive lifespan.
2Productivity
If a pair of rollers with a continuous web of adhesive sheet is used to extend usage, then the adhesive sheet can be continuously supplied, but the rollers are not consistently aligned causing misalignment and jamming
Solution Approach 1:
Instead of attempting to align two active rollers that both rotate and interact with the adhesive sheet, the invention makes one roller passive (the support arm) and the other active (the rotating roller). This inversion of roles eliminates the alignment instability caused by two actively rotating rollers.
Solution Approach 2:
A support arm is introduced as an intermediary component between the two rollers. The support arm provides a stable, non-rotating mounting structure that holds one roller in fixed alignment, mediating the interaction between the two rollers and eliminating misalignment issues.
3Productivity
If a double-sided adhesive sheet on a single roller is used, then the sheet can be used multiple times, but it lacks the capability of being transferred between rollers and automatically separating the release liner
Solution Approach 1:
The system is segmented into two distinct rollers with different functions: one roller handles the adhesive sheet transfer and cleaning function, while the other roller handles the release liner separation function. This segmentation allows each roller to be optimized for its specific task.
Solution Approach 2:
The support arm acts as an intermediary structure that enables the transfer of the adhesive sheet between rollers while providing the mechanical advantage needed for automatic release liner separation. It mediates the complex interaction between the adhesive sheet, release liner, and rollers.
4Length of moving object
If the adhesive sheet length is increased to extend usage, then the total surface area increases, but the roller alignment becomes more difficult to maintain
Solution Approach 1:
Instead of having both rollers rotate and maintain alignment over a long adhesive sheet, the invention makes one roller stationary (on the support arm) and only the other roller rotates. This inversion reduces the complexity of maintaining alignment precision over long sheet lengths.
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
This system allows for efficient and repeated use of the adhesive sheet by maintaining roller alignment and utilizing both sides of the adhesive, extending the cleaning capacity and reducing the need for frequent replacements.
Implementation Method 1
The adhesive sheets are configured so that debris is adhered thereto with a continuous supply of a debris-free section of the adhesive sheet

AI summary
An adhesive cleaning system for cleaning surfaces provided with a cleaning unit including at least two support arms in a spaced apart and parallel relationship with each other. Each of the support arms has a stop edge, a free end and at least one annular ridge. A first roller and a second roller each include a roller core rotatably receiving at least one of the support arms, respectively. An adhesive sheet is transferable between the rollers, with the adhesive sheet including a release liner, a first adhesive layer, a second adhesive layer and a backing layer. During use the first adhesive layer is exposed when wound on one of the rollers, with the second adhesive layer is exposed when transferred to the other roller, thereby provide multiple uses of the adhesive sheet.
