Dual-Roll Lint Roller for Maneuverable Large-Surface Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large lint rollers are cumbersome to maneuver while providing a sufficient surface area for picking up debris, as they quickly become loaded with lint, hair, and other items like bedding, necessitating frequent sheet replacements.
Innovation Solution
A lint roller design featuring at least two independently rotating tape rolls supported by a single handle, allowing for enhanced maneuverability and increased surface area for debris pickup, with the rolls' positions varying in alignment to optimize handling and cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a single large lint roller is used, then the surface area for picking up debris is increased, but the device becomes cumbersome to maneuver
Solution Approach 1:
The patent divides a single large lint roller into multiple smaller lint roller units (first lint roller unit, second lint roller unit, etc.), each with its own independently rotatable lint tape roll. This segmentation allows each unit to be maneuvered independently, improving ease of operation while collectively providing sufficient surface area for debris pickup through the plurality of rolls.
2Quantity of substance
If a larger lint roller is used to pick up more debris, then the surface area is increased, but the frequency of sheet replacement must increase
Solution Approach 1:
By dividing the lint collection function across multiple independently rotatable rolls, the system can continue collecting debris on other rolls while one roll's sheet is being replaced, effectively reducing the perceived frequency of replacement and maintaining continuous debris pickup capability.
Solution Approach 2:
The multiple independently rotatable rolls ensure that while one roll may be reaching the end of its debris pickup capacity, other rolls remain active and capable of continued debris collection, maintaining continuous useful action without interruption.
3Area of moving object
If multiple independently rotating tape rolls are used, then the surface area for debris pickup is increased and maneuverability is improved, but the device complexity increases
Solution Approach 1:
The patent employs multiple modular lint roller units, each containing an independently rotatable roll within a housing. This segmented modular design allows the complexity to be distributed across identical or similar units, making the overall system manageable despite having multiple independent rotating components.

AI summary
Disclosed is a lint roller having a handle, and first roll of tape and a second roll of tape. The handle has a support having a first portion and a second portion. The first roll of tape has an outwardly facing surface with adhesive and rotatable about the first portion of the support. The second roll of tape has an outwardly facing surface with adhesive and rotatable about the second portion of the support.
