Solution Overview
Problem
Existing containers for storing heat-sensitive products do not effectively minimize radiant, convective, and conductive heat transfer, nor do they eliminate the detrimental effects of oxygen, leading to reduced storage duration and freshness.
Innovation Solution
A vacuum-cooled container with a radiation reflective material and a substantial vacuum space that reduces heat transfer through conduction and convection by removing air molecules and oxygen, while maintaining a stable temperature.

Engineering Contradiction Analysis
1Duration of action of moving object
If traditional insulated coolers are used to store heat-sensitive products, then the products can be stored for a limited time, but the storage duration is reduced due to ineffective heat transfer minimization and oxygen presence
Solution Approach 1:
The patent applies vacuum sealing to create an inert environment by removing air and oxygen from the storage chamber. This eliminates oxidative spoilage and reduces heat transfer through conduction and convection, thereby extending storage duration while protecting products from harmful factors
Solution Approach 2:
The invention extracts harmful elements (air molecules and oxygen) from the storage environment by applying vacuum technology. This removal of detrimental substances directly addresses the harmful factors limiting storage duration without requiring active cooling systems
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 container extends the storage duration of heat-sensitive products by minimizing heat transfer and reducing oxygen-induced spoilage, thereby maintaining freshness for longer periods without the need for a power source.

AI summary
A cooler capable of achieving a sufficient temperature gradient between an inside of the cooler and an outside of the cooler such that at least a partial vacuum forms within the cooler may include an enclosure defined by at least one wall and a lid. The lid may form a relatively airtight seal with a wall of the cooler when in a closed position. A vacuum release assembly may be disposed in one of the walls or lid of the cooler, the assembly being capable of reducing a pressure differential between the enclosure and the outside of the cooler.
