Foldable Mop Cover Holder With Angled Projections for Uniform Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mop cover holders are not designed to facilitate easy and quick changes of mop covers while ensuring uniform contact pressure and preventing the mop cover and holder from shifting during use.
Innovation Solution
A mop cover holder with articulated, lockable, foldable wings featuring projections that extend at an angle other than 90°, providing additional pressure and stability, combined with a locking device accessible from the handle side for easy operation, ensures secure contact and minimal movement of the mop cover during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If projections are arranged perpendicular to the mop plate (90° angle), then the structure is simple and manufacturing is easy, but the mop cover can shift or slide during use and contact pressure is not uniform
Solution Approach 1:
The patent changes the angle parameter of the projections from the conventional 90° to an angled configuration (not perpendicular to the mop plate surface). This parameter change allows the projections to exert pressure at an optimal angle that prevents mop cover sliding while maintaining manufacturing feasibility through standard forming processes.
Solution Approach 2:
The patent applies different functional qualities to different parts of the mop plate: the projections are angled to provide localized anti-slip functionality, while the overall plate structure remains simple for easy manufacturing. This local differentiation of quality resolves the contradiction between simple structure and reliable grip.
2Device complexity
If the mop plate structure is simple and robust, then manufacturing is easy and the device is durable, but it cannot provide uniform contact pressure and prevent shifting during use
Solution Approach 1:
By changing the angular parameter of the projections from perpendicular to angled, the patent achieves uniform contact pressure distribution across the mop cover surface without complicating the overall plate structure. The angled geometry naturally distributes pressure more evenly during the wiping motion.
Solution Approach 2:
The patent introduces a new dimensional aspect to the projections by angling them relative to the plate surface, rather than keeping them perpendicular. This dimensional change enables the projections to engage the mop cover in both vertical and lateral directions, preventing shifting while maintaining structural simplicity.
3Ease of operation
If the locking device is accessible from the handle side, then operation is easy and quick, but the structure becomes more complex
Solution Approach 1:
The mop handle serves multiple functions: it provides the articulation connection for the mop plate and simultaneously serves as the access point for operating the locking device. This multi-functionality allows easy operation without adding separate control mechanisms that would increase structural complexity.
Solution Approach 2:
The locking device is integrated into the existing handle structure, allowing the handle itself to facilitate its own operation. The user interacts with the locking mechanism through the handle, eliminating the need for separate controls and maintaining structural simplicity while achieving ease of operation.
