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, as they require separate carrying and prolonged contact with the article to achieve desired temperature, with inefficient heat transfer.
Innovation Solution
A temperature control pouch pack design featuring multiple pouches: a first pouch filled with reaction fluid and material, a second pouch for article accommodation, and optionally a third pouch for enhanced heat exchange, with communication channels and sealing to facilitate rapid temperature control through chemical 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 structure is simple, but it is inconvenient to carry and use
Solution Approach 1:
The patent combines the temperature control pouch pack with the article container into a single integrated unit. The pouch pack is positioned to surround or contact the article directly within the same package structure, eliminating the need for separate carrying and application steps.
Solution Approach 2:
The integrated design serves multiple functions simultaneously: the outer packaging protects the article during transport, while the embedded pouch pack provides temperature control. This multi-functional structure eliminates the need for separate temperature control devices.
2Temperature
If the article is kept in contact with the temperature control pouch pack for prolonged time, then the desired temperature is achieved, but it causes inconvenience to the user
Solution Approach 1:
The temperature control pouch pack is pre-positioned in direct contact with the article within the integrated package before use. This preliminary positioning ensures immediate heat transfer when activated, eliminating the need for prolonged contact time and frequent adjustment by the user.
3Temperature
If the article contacts the temperature control pouch pack, then temperature control is achieved, but a relatively long time is taken to reach the desired temperature
Solution Approach 1:
The pouch pack is nested within or around the article in a concentric arrangement, maximizing the surface area contact between the heat transfer medium and the article. This nested configuration significantly increases heat transfer efficiency and reduces the time required to reach the desired temperature.
Solution Approach 2:
The design transitions from surface contact to three-dimensional surrounding contact, where the pouch pack envelops the article on multiple sides simultaneously. This spatial arrangement dramatically increases the heat transfer area and reduces thermal resistance, enabling faster temperature control.
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 pouches and utilizing chemical reactions for efficient heat transfer, reducing user inconvenience and time to reach desired temperatures.
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
