Scrubber Glove Cuff Structure to Stop Chemical Drips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Protective gloves used for scrubbing with harsh chemicals often allow aqueous solutions to drip down the arm and onto the user's skin or clothes when scrubbing overhead, posing a risk of chemical exposure.
Innovation Solution
A glove system featuring a tubular hand component with scrubber reliefs and a flexible arm component, combined with a rigid cuff that includes a direction-reversing transition to prevent liquids from running down the arm, utilizing flexible and rigid materials to maintain structure and prevent dripping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible glove is used for scrubbing, then ease of operation is improved, but liquid containment capability deteriorates
Solution Approach 1:
The glove is divided into two distinct segments: a flexible hand portion for ease of operation and a rigid cuff portion for liquid containment. This segmentation allows each part to fulfill its specific function optimally without compromising the other.
Solution Approach 2:
Different parts of the glove have different mechanical properties - the hand portion is flexible to allow dexterity while the cuff portion is rigid to prevent liquid runoff. This local differentiation of material properties resolves the contradiction between flexibility and liquid containment.
2Reliability
If a rigid cuff is used to prevent liquid runoff, then liquid containment capability is improved, but ease of operation deteriorates
Solution Approach 1:
The rigid cuff is segmented from the flexible hand portion, creating a clear boundary between the liquid-containing function and the operational function. This allows the rigid structure to provide containment without restricting hand movement.
Solution Approach 2:
The rigid quality is localized specifically to the cuff portion where liquid containment is needed, while the hand portion maintains flexibility for operation. This localized application of rigidity resolves the contradiction.
3Reliability
If the cuff structure is made more complex to prevent dripping, then liquid containment capability is improved, but device complexity increases
Solution Approach 1:
The liquid containment function is extracted from the flexible glove material and implemented through a separate rigid cuff structure. This extraction creates a simple, dedicated solution for preventing drips without complicating the overall glove design.
Solution Approach 2:
The material parameter of the cuff is changed from flexible to rigid, fundamentally altering its behavior to prevent liquid runoff. This parameter change provides an elegant, simple solution to the dripping problem without requiring complex structural features.

AI summary
A glove system that prohibits an aqueous solution used with a glove from running down an elevated arm onto a body of a user features a tubular glove hand component that is flexible. The system features a scrubber component located on a hand component palmar surface with a plurality of linear scrubber component reliefs located at each movable joint area of the hand component palmar surface. The system features a tubular glove arm component designed to cover a wrist and a forearm of the user. The system features a rigid glove cuff having a cylindrical cuff wall and an outer cuff wall. An intersection of a cylindrical cuff wall second end and an outer cuff wall second end features a direction reversing transition designed to offset an outer cuff wall inside surface from a cylindrical cuff wall outside surface an offset distance.
