Packaging box for cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging boxes for chilled food deliveries often suffer from inadequate cooling functions, leading to food deterioration and increased resource waste due to inefficient insulation and incomplete cooling, especially with longer delivery distances and times.
Innovation Solution
A folding packaging cooler box with a double cooling structure, featuring a cooling reinforcing portion that forms a hexahedron shape with the box portion, allowing for enhanced cooling, easy automated cleaning, and portable design, minimizing thermal losses and waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an insulating member is attached to the packaging box to improve insulation, then the cooling function is enhanced, but the packaging waste increases exponentially
Solution Approach 1:
The packaging box is designed to be foldable and reusable rather than disposable. The insulating member can be detached and reused across multiple deliveries, transforming the static disposable packaging into a dynamic reusable system that maintains cooling function while reducing waste.
Solution Approach 2:
The insulating member is designed to be separable from the box structure, allowing it to be recovered and reused for subsequent deliveries. This separation enables the insulation component to serve multiple cycles rather than being discarded with each use.
2Loss of substance
If the packaging box is designed for reuse to reduce waste, then packaging waste decreases, but the cooling function becomes insufficient for long deliveries
Solution Approach 1:
The packaging system is divided into separate functional components: the box structure, the insulating member, and the refrigerant container. This segmentation allows each component to be optimized independently - the box for reuse, the insulation for thermal performance, and the refrigerant for active cooling - achieving sufficient cooling for long deliveries while maintaining reusability.
Solution Approach 2:
The packaging employs a composite structure combining the box material, insulating material, and refrigerant system. This composite approach integrates passive insulation with active refrigeration, creating a hybrid cooling system that maintains reliability for extended deliveries while preserving the reusable nature of the packaging.
3Reliability
If a complex cooling structure is implemented to enhance cooling function, then the cooling reliability improves, but the device complexity increases
Solution Approach 1:
The cooling system is segmented into modular components that can be independently assembled and disassembled. The insulating member and refrigerant container are separate entities that attach to the basic box structure, allowing the complex cooling function to be achieved through simple component assembly rather than integrated complex design.
