Nested Insulated Packaging Assembly for Temperature-Controlled Shipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Packaging perishable and temperature-sensitive items poses challenges in minimizing spoilage, browning, bruising, and transit breakage during shipping, as existing solutions fail to provide effective temperature control and cushioning.
Innovation Solution
A nested insulated packaging assembly comprising an outer box, an inner box, and two thermal liners that contact the lateral side walls of both boxes, providing a cushioned and climate-controlled environment through the use of materials like polyester film and foams, which can be biodegradable or recycled, to maintain temperature and protect contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing packaging solutions are used, then shipping is possible, but temperature control and cushioning are insufficient leading to spoilage and transit breakage
Solution Approach 1:
The patent implements a nested packaging structure where an inner box containing the perishable item is placed inside an outer box. Thermal liners are positioned in the outer box surrounding the inner box, creating multiple protective layers. This nested configuration provides enhanced temperature control and cushioning without requiring a completely new packaging system, thereby improving reliability while protecting against spoilage and breakage.
2Temperature
If thermal liners contact both outer and inner box walls, then temperature control is improved, but device complexity increases
Solution Approach 1:
The thermal liners serve dual functions by simultaneously contacting the outer box walls and inner box walls. This merging of functions allows a single component to provide both insulation from the external environment and direct thermal protection to the inner box, achieving consistent temperature control without proportionally increasing complexity.
Solution Approach 2:
The thermal liners are designed to perform multiple functions: insulating the outer box from external temperature variations, cushioning the inner box, and directly contacting the inner box walls to maintain temperature. This multi-functionality reduces the need for separate components, thereby managing complexity while achieving temperature consistency.
3Reliability
If nested box structure with thermal liners is used, then temperature control and cushioning are provided, but manufacturing complexity increases
Solution Approach 1:
The packaging system is divided into distinct segments: an outer box, an inner box, and thermal liners as separate components. This segmentation allows each component to be manufactured independently using standard processes, then assembled together. The modular nature simplifies manufacturing while providing comprehensive protection against spoilage and breakage.
4Strength
If inner box is received in outer box with thermal liners, then cushioning is provided, but volume efficiency decreases
Solution Approach 1:
The thermal liners function as flexible insulating layers that conform to the space between the outer and inner boxes. These thin film structures provide effective cushioning and thermal protection without adding significant volume, thereby maintaining space efficiency while delivering protection against breakage.
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 nested insulated packaging effectively maintains temperature and provides cushioning, reducing spoilage and transit damage by creating a protected environment for perishable and pharmaceutical items, enabling the co-shipment of items requiring different temperature profiles.
Implementation Method 1
a first thermal liner contacting a one of the outer lateral side walls of the outer box and a one of the inner lateral side walls of the inner box
Implementation Method 2
creating an insulated cavity for temperature maintenance and cushioning
