Repulpable Insulated Container Insert for Compact Recyclable Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Packaging perishable or temperature-sensitive items poses challenges due to spoilage, destabilization, freezing, melting, or evaporation when temperature is not maintained, and existing insulated packages are often bulky, non-recyclable, and end up in landfills.
Innovation Solution
An insulated container assembly using a cardboard outer box with a repulpable insulation insert made from a cardboard sheet and insulation batt, where the insulation batt is adhesively attached to the sheet and extends through crease lines to define a cavity, allowing for easy assembly and potential recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional insulated packages are used to maintain temperature for perishable items, then temperature protection is provided, but the packages become bulky and difficult to store
Solution Approach 1:
The insulated insert is designed to be nested within the cardboard box, with the insulation batt folded along crease lines to create a compact three-dimensional structure that fits efficiently inside the box cavity, reducing overall package volume while maintaining insulation capability
Solution Approach 2:
The insulation batt is used in a thin, flexible configuration that can be folded and shaped to fit within the box, replacing traditional bulky rigid insulation structures with a flexible thin-film approach that provides temperature protection in a compact form
2Temperature
If traditional insulated packages are used for temperature-sensitive shipping, then temperature maintenance is achieved, but the packages cannot be recycled and end up in landfills
Solution Approach 1:
The insulated insert is constructed entirely from recyclable materials (cardboard and paper-based insulation batt) that can be recovered and recycled after use, eliminating the need for landfill disposal and enabling material recovery cycles
Solution Approach 2:
The package uses a composite structure combining cardboard outer box with paper-based insulation batt, where both materials are inherently recyclable and can be processed together through recycling streams, creating an environmentally sustainable temperature maintenance solution
3Volume of moving object
If insulation batt is adhesively attached to cardboard sheet extending through crease lines, then compact and recyclable structure is achieved, but assembly complexity increases
Solution Approach 1:
The insulated insert is segmented into foldable sections along crease lines, allowing the insulation batt and cardboard sheet to be divided into manageable segments that can be assembled by simple folding and adhesive application rather than complex fastening operations
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 solution provides effective temperature maintenance for sensitive items while being more compact and recyclable, reducing waste by using repulpable materials that can be reused or recycled.
Implementation Method 1
