Solution Overview
Problem
Existing refrigerant packs are heavy and bulky due to the presence of refrigerant fluid, making them costly to transport and store.
Innovation Solution
A system that uses a waterproof Super Absorbent Material (SAM) pack without refrigerant fluid, which is filled with refrigerant fluid and then sealed to create a refrigerant pack, reducing weight and volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If refrigerant fluid is included in the pack, then cooling capacity is maintained, but weight and volume increase
Solution Approach 1:
The patent applies preliminary action by pre-packaging the absorbent material (SAM) in a waterproof bag before use. The SAM is prepared and sealed in advance without refrigerant fluid, then later filled with refrigerant fluid at the point of use. This allows the absorbent material to be ready and prepared beforehand, reducing the weight and volume during transportation and storage, while maintaining the ability to achieve full cooling capacity when needed.
2Temperature

The SAM is prepared and sealed in advance without refrigerant fluid, then later filled with refrigerant fluid at the point of use. This allows the absorbent material to be ready and prepared beforehand, reducing the weight and volume during transportation and storage, while maintaining the ability to achieve full cooling capacity when needed.
3Ease of operation
If the pack is filled with refrigerant fluid before use, then cooling function is ready, but the pack becomes heavy and bulky
Solution Approach 1:
The patent applies preliminary action by pre-packaging the absorbent material (SAM) in a waterproof bag before use. The SAM is prepared and sealed in advance without refrigerant fluid, then later filled with refrigerant fluid at the point of use. This allows the absorbent material to be ready and prepared beforehand, reducing the weight and volume during transportation and storage, while maintaining the ability to achieve full cooling capacity when needed.
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 allows for efficient transportation and storage of refrigerant packs by reducing weight and volume, while maintaining the cooling capacity of traditional packs.
Implementation Method 1
the absorbent material is a Super Absorbent Material (SAM) such as Super Absorbent Polymer (SAP)
Implementation Method 2
the adding refrigerant fluid to the inside of the SAM pack includes adding refrigerant fluid to the inside of the SAM pack through a side of the SAM pack
