Water Balloon Colorant with Redox-Sensitive Dye
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water balloon compositions fail to provide a safe and effective way to indicate a 'hit' during water balloon fights, as they either use hazardous substances, are prone to leakage, or lack sufficient weight and durability.
Innovation Solution
Development of a water balloon system that incorporates an automatically clearing composition, which changes from a visible color to clear upon drying or oxidation, using a redox-sensitive dye and potentiating agent, such as methylene blue and sodium perborate, encapsulated in vesicles within the balloon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If paints and dyes are used to indicate a hit, then visibility of the hit is improved, but safety deteriorates due to hazardous substances and skin irritation
Solution Approach 1:
The patent uses pH-sensitive dyes that undergo parameter change in their color properties when exposed to specific pH conditions. The dye remains invisible at neutral pH (safe for skin) and transforms to a visible color when exposed to the acidic urine, providing hit indication without skin irritation hazards.
Solution Approach 2:
The invention employs color-changing dyes that transition between visible and invisible states based on pH conditions. The dye is designed to be colorless at neutral pH and changes color when exposed to acidic environments, enabling safe and effective hit indication.
2Illumination intensity
If pH-sensitive dyes are used to indicate hit, then visibility is improved, but safety deteriorates due to requirement for strongly acidic or basic solutions that irritate skin and eyes
Solution Approach 1:
The patent utilizes pH-sensitive dyes that undergo parameter change in their color properties when exposed to specific pH conditions. The dye remains invisible at neutral pH (safe for skin) and transforms to a visible color when exposed to the acidic urine, providing hit indication without skin irritation hazards.
3Reliability
If water-insoluble film-forming polymers are added to prevent rubbing off, then durability is improved, but practicality deteriorates because the composition becomes water-insoluble and cannot be used in water balloons
Solution Approach 1:
The patent employs polymers that undergo parameter changes in solubility based on pH conditions. The polymer remains water-insoluble at neutral pH (providing durability) and becomes water-soluble when exposed to acidic environments (allowing it to be used in water balloons), thus adapting to different conditions.
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 system provides a safe and visually effective way to indicate a 'hit' during water balloon fights, ensuring the composition is non-irritating and maintains visibility until it automatically clears, addressing the limitations of previous technologies.
Implementation Method 1
a colorant that changes from visible to clear at different redox states, and more preferably following contact with a redox potentiating agent, whether oxidizer or reducer
Implementation Method 2
automatically clearing composition, which changes from a visible color to clear upon drying or oxidation
