Disposable Cuff Clip with pH Indicator for Scrub Garments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In healthcare facilities, the loose-fitting pants leg cuffs of scrubs frequently come into contact with contaminated floor surfaces, leading to the spread of germs and pathogens, and existing solutions are either expensive or impractical to implement.
Innovation Solution
A disposable clothing cuff clip that attaches to the cuff of an article of clothing, lifting it off the floor and providing a barrier, with an optional contamination indicator that changes appearance in response to moisture or pH changes to indicate contact with contaminated surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If loose-fitting scrub pants are worn for comfort, then wearer comfort is improved, but the pants leg cuffs drag on the floor and spread contaminants
Solution Approach 1:
The cuff clip acts as an intermediary device between the pants cuff and the floor. It attaches to the cuff and extends downward to contact the floor, creating a barrier that prevents direct contact between the contaminable cuff and contaminated floor surfaces, thereby solving the contradiction between maintaining loose fit and preventing contamination spread
2Object-affected harmful factors
If better fitting clothing is provided to prevent cuff contact with floors, then contaminant spread is reduced, but cost increases due to requiring multiple sizes
Solution Approach 1:
The cuff clip is designed as an inexpensive, disposable component that can be attached to any size of pants cuff. Rather than manufacturing expensive custom-fit clothing for each size, this single standardized clip solution prevents contamination for all pant sizes equally, dramatically reducing costs while maintaining effectiveness
3Object-affected harmful factors
If a mechanism is added to lift cuffs off the floor, then contaminant contact is reduced, but device complexity increases
Solution Approach 1:
The solution segments the pants leg into two functional zones: the upper portion that remains loose and comfortable for the wearer, and the lower cuff portion that is gathered and lifted by the clip. This segmentation allows the complex function of contamination prevention to be isolated to a small component without affecting the overall simplicity and comfort of the pants
4Difficulty of detecting and measuring
If a contamination indicator is added to the cuff clip, then contamination detection is improved, but manufacturing complexity increases
Solution Approach 1:
The contamination indicator utilizes color change technology that reacts to moisture or chemical contaminants. When the indicator changes color, it provides immediate visual feedback to the wearer about contamination levels. This approach adds detection capability without requiring complex electronics or mechanisms, maintaining manufacturing simplicity while significantly improving contamination awareness
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
Effectively reduces contact between contaminated floor surfaces and clothing, providing a secure, easy-to-use, and cost-effective solution for various clothing sizes, while offering a visual indication of contamination exposure.
Implementation Method 1
a contamination indicator that changes in appearance when subjected to significant moisture and/or a significant change in pH or chemical composition

AI summary
A clothing cuff clip attachable to an article of clothing, especially a pants leg cuff, to gather and lift the clothing up from an adjacent surface and provide a modest barrier between the surface and the clothing item being worn. The clothing cuff clip is inexpensive to manufacture in large quantities and may be disposable after extended use. The clip is easy to attach to the lower back edge of the pants leg cuff on the item of clothing being worn and yet remains securely attached even after extended use. Optionally, a contamination indicator that changes in appearance when subjected to significant moisture, a change in pH, or the presence of a selected contaminant material, is positioned on the lower floor contact area of the clip to provide the wearer with an indication of when the clip, and therefore the item of clothing, has come into contact with contaminated materials.
