Integrated Temperature-Control Pouch Pack for Faster Heat Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional temperature control pouch packs are inconvenient to use and maintain, requiring separate carrying and prolonged contact with the article to achieve desired temperature, due to inefficient heat transfer.
Innovation Solution
A temperature control pouch pack design featuring a first pack filled with a reaction fluid and material, a second pack for article accommodation, and a third pack that communicates with the first pack to enhance heat exchange, allowing rapid temperature control through endothermic or exothermic reactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional temperature control pouch pack is used separately from the article, then the reaction fluid pouch can be torn to initiate the reaction, but it is inconvenient to maintain and use
Solution Approach 1:
The patent integrates the reaction fluid pouch, reaction material pouch, and article storage pouch into a single unified temperature control pouch pack. The reaction fluid pouch and reaction material pouch are positioned to contact the article storage pouch, enabling the user to initiate the reaction by simply pressing the external surface of the integrated pack, eliminating the need for separate carrying and manual pouch tearing.
Solution Approach 2:
The patent employs a nested structure where the reaction fluid pouch and reaction material pouch are contained within the same external pack as the article storage pouch. The reaction fluid pouch is positioned inside the external pack, and the reaction material pouch is also contained within, creating a compact nested arrangement that simplifies the overall device structure and improves ease of use.
2Reliability
If the article is kept in contact with the temperature control pouch pack until the desired temperature is reached, then the temperature control function is achieved, but it causes inconvenience to the user
Solution Approach 1:
The patent enhances the thermal interaction interface by positioning the reaction fluid pouch and reaction material pouch to directly contact the article storage pouch at specific locations. This localized optimization of heat transfer pathways ensures efficient temperature control while allowing the article to be quickly removed once the desired temperature is reached, improving user convenience.
3Reliability
If the article contacts the temperature control pouch pack, then the temperature can be controlled, but a relatively long time is required to reach the desired temperature due to heat transfer efficiency
Solution Approach 1:
The patent optimizes heat transfer by positioning the reaction fluid pouch and reaction material pouch to directly contact the article storage pouch at multiple locations. This creates multiple localized heat transfer pathways, significantly improving the overall heat transfer efficiency and reducing the time required to reach the desired temperature while maintaining reliable temperature control.
Solution Approach 2:
The patent enhances heat transfer by transitioning from a single-point or single-surface contact to a multi-dimensional thermal interaction network. The reaction fluid pouch and reaction material pouch are strategically positioned to contact the article storage pouch at multiple points and surfaces, creating a three-dimensional heat transfer system that accelerates temperature equalization.
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
Enables convenient carrying and quick temperature attainment for articles by integrating the pouch packs and optimizing heat transfer, reducing the time required to reach a desired temperature.
Implementation Method 1
an endothermic or exothermic reaction arises between the reaction fluid and the reaction material and cools or heats a surface of the temperature control pouch pack
Implementation Method 2
an endothermic or exothermic reaction arises between the reaction fluid and the reaction material and cools or heats a surface of the temperature control pouch pack
Implementation Method 3
a second pack which is disposed to exchange heat with the first pack and accommodates an article of which temperature is in need of control
Implementation Method 4
the third pack being filled with a second reaction material that reacts with the reaction fluid flowed out from the first pack and causes a predetermined reaction
