Lint Roller Agitator Arm and End Cap for Better Debris Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lint rollers often struggle to effectively remove debris such as lint and hair from surfaces due to inadequate adhesive strength, leaving residue behind.
Innovation Solution
A lint roller assembly with an integral agitator arm and end cap design, where the agitator arm features a deformable section and a rotatable end cap that secures the tape roll, providing mechanical support and preventing debris from being pushed further into the surface, allowing the agitator to loosen debris for easier removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive tape is used to remove debris, then debris can be collected on the tape surface, but the adhesive strength is insufficient to separate debris from the surface
Solution Approach 1:
The agitator performs preliminary action by loosening and lifting debris from the surface before the adhesive tape contacts it. This pre-treatment prepares the debris for easier removal by the tape, addressing the insufficient adhesive strength problem.
Solution Approach 2:
The agitator acts as an intermediary between the adhesive tape and the debris. It first interacts with the debris to loosen it, then the tape collects the pre-loosened debris, effectively bridging the gap between weak adhesive force and the need for strong debris separation.
2Reliability
If a deformable section is added to the agitator arm, then the agitator can effectively loosen debris, but the device complexity increases
Solution Approach 1:
The deformable section is implemented as a flexible, thin-walled portion in the agitator arm that bends under pressure to allow bristle deformation. This flexible design achieves effective debris loosening while maintaining relatively simple construction compared to complex mechanical mechanisms.
3Stability of the object's composition
If an end cap is added to secure the tape roll, then the tape roll remains stable during use, but the device complexity increases
Solution Approach 1:
The end cap is implemented as a separate, modular component that attaches to the agitator arm. This segmentation allows the stabilizing function to be added independently without redesigning the entire assembly, thus improving tape roll stability while minimizing overall complexity increase.

AI summary
A cleaning apparatus configured for removing debris or lint from clothing by agitating lint and then rolling it off. The cleaning apparatus includes a handle with a first end and a second end, a cleaning roll support extending from the handle second end and terminating at a distal end, an agitator arm extending from the handle second end parallel to the cleaning roll support and terminating at a distal end and an end cap rotatably connected to the agitator arm distal end. The end cap is configured to be rotatable between an open position away from the cleaning roll support and a closed position in which the end cap engages with the distal end of the cleaning roll support.
