Waterproof Wash Mitt Structure to Prevent Spinning and Scratching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing mitt devices either allow the mitt to spin on the user's hand during use or lack a waterproof barrier, failing to keep the user's hand dry and often feature a multi-faceted outer layer that can scratch surfaces.
Innovation Solution
A waterproof glove body is integrated within a mitt body with a micro fibrous outer side, featuring a continuous perimeter that couples with the mitt's open bottom edge, along with an elasticized wristband and sleeve to secure the user's hand, ensuring the mitt remains in place and the hand remains dry during washing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof barrier is added to keep the user's hand dry, then the hand dryness is improved, but the device complexity increases
Solution Approach 1:
The glove body is nested within the mitt body, creating a layered structure where the waterproof glove is inserted into the mitt cavity. This nesting approach allows the waterproof barrier to be integrated without adding external complexity, as the glove becomes part of the mitt's internal structure rather than a separate component.
Solution Approach 2:
The glove body and mitt body are merged into a single integrated apparatus where the glove perimeter is continuously coupled to the mitt perimeter. This merging eliminates the need for separate waterproofing mechanisms while maintaining both the drying function of the mitt and the waterproof protection of the glove.
2Ease of operation
If the mitt is made open-pocketed for flexibility, then the ease of operation is improved, but the mitt spinning on the hand worsens
Solution Approach 1:
The glove body is nested within the open-pocketed mitt body, and the continuous coupling of the glove perimeter to the mitt perimeter creates a unified structure that prevents spinning while preserving the flexibility of the open-pocket design.
Solution Approach 2:
The continuous perimeter coupling creates a flexible seal between the glove and mitt that adapts to hand movements while preventing rotation. This flexible connection maintains ease of operation while ensuring positional stability during use.
3Productivity
If a multi-faceted outer layer is used for washing, then the washing capability is improved, but the surface scratching worsens
Solution Approach 1:
The mitt body features a micro fibrous outer side specifically designed for scratch-free cleaning, while the glove body provides waterproof protection. Each component has optimized local properties: the mitt for gentle cleaning and the glove for waterproofing, resolving the contradiction between washing effectiveness and surface protection.
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
The solution effectively keeps the user's hand dry and prevents scratching of surfaces while maintaining the mitt's position, allowing for efficient and scratch-free cleaning.
Implementation Method 1
The wristband (46) is elasticized and coupled to the mitt perimeter (44) to compress against the user's wrist and secure the user's hand within the glove body (32) and the mitt body (12)
Implementation Method 2
The mitt body (12) has a micro fibrous outer side (30) configured to dry dust or wet wash a surface without creating scratches

AI summary
A gloved wash mitt apparatus for keeping a mitt in place while maintaining dry hands includes a mitt body having a mitt top side, a mitt bottom side, a mitt left edge, a mitt right edge, a mitt top edge, and an open mitt bottom edge defining a mitt cavity. The mitt body has an outer side to dry dust or wet wash a surface without creating scratches. A glove body is coupled to the mitt body within the mitt cavity. The glove body has a glove palm portion, a plurality of glove finger portions extending from the glove palm portion, a glove wrist portion coupled to the glove palm portion, and an open glove bottom side. A glove perimeter of the glove wrist portion is continuously coupled to a mitt perimeter of the open mitt bottom edge. The glove body is waterproof.
