Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coolants can become too cold immediately after cooling, causing discomfort and pain due to rapid temperature drop.
Innovation Solution
A coolant comprising two types of solids, at least one of which is an agglomerated mass, that undergo an endothermic reaction when brought into contact, with specific size and shape parameters to control the cooling rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional coolants use fine powder or liquid formulations, then the cooling reaction starts rapidly, but the coolant becomes too cold immediately causing pain and discomfort
Solution Approach 1:
The coolant components are segmented into granular particles with specific size ranges (0.6-2.0mm for first component, 0.3-1.5mm for second component) rather than using fine powders or liquids. This segmentation controls the reaction surface area and prevents excessive rapid cooling while maintaining effective cooling function.
2Object-affected harmful factors
If the coolant uses large particle sizes, then the cooling is more gradual and comfortable, but the cooling efficiency and reaction speed decrease
Solution Approach 1:
The patent optimizes specific particle size parameters (0.6-2.0mm and 0.3-1.5mm ranges) to achieve the best balance between gradual comfortable cooling and sufficient cooling efficiency. These parameter changes transform the particle morphology from fine powder to controlled granular structure.
3Quantity of substance
If the coolant uses liquid or fine powder form, then the contact area between components is large, but the reaction occurs too quickly causing temperature to drop below comfortable levels
Solution Approach 1:
Both coolant components are segmented into granular particles with controlled size distributions, creating sufficient contact area for effective cooling while preventing excessive reaction speed that would cause uncomfortable temperature drops.
Solution Approach 2:
The granular structure provides localized contact points between components rather than uniform mixing, allowing controlled reaction progression and preventing sudden temperature drops while maintaining adequate cooling surface area.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
