Solution Overview

Problem

Conventional insulated containers for keeping food and drinks cool or warm are often bulky, inefficient in space usage, and require ice or gel packs that can be messy or difficult to manage, especially when trying to maintain temperature for extended periods.

Innovation Solution

A collapsible insulated container with pliable walls containing gel packs that can be folded into a compact condition for storage and easily chilled or heated, featuring strategically placed crease lines and fastener straps for easy folding and unfolding, allowing for efficient use of space and effective temperature maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If conventional insulated containers use ice or gel packs for cooling, then the cooling effect is achieved, but the container becomes bulky and takes up significant space

Engineering Contradiction:
Improvecooling effectVSAvoidcontainer size
Core Design Contradiction:
TemperatureVSVolume of moving object

Solution Approach 1:

The gel packs are integrated within the wall structure of the container itself, nesting the cooling function inside the container walls rather than requiring separate external ice packs. This eliminates the need for additional space while maintaining the cooling effect.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The container walls serve multiple functions: structural support, insulation, and cooling storage. The gel packs embedded in the walls provide both structural integrity and thermal regulation, making the container multi-functional and space-efficient.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Strength

If conventional insulated containers are designed with rigid walls for structural support, then durability is improved, but the container becomes difficult to fold and store compactly

Engineering Contradiction:
Improvestructural supportVSAvoidfoldability
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The container uses flexible pliable walls instead of rigid structures. The walls are made of flexible materials that can be folded and collapsed while still providing adequate structural support and maintaining the integrity of the gel packs within.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The container transitions from a rigid, fixed structure to a dynamic, flexible structure that can change shape. The pliable walls allow the container to be collapsed into a compact form for storage while maintaining structural integrity during use.

Inventive Principle:
Principle #15Dynamics

3Temperature

If gel packs are placed in the container for cooling, then temperature maintenance is improved, but the gel packs can be lost or misplaced

Engineering Contradiction:
Improvetemperature maintenanceVSAvoidgel pack management
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

The gel packs are merged with the container structure by embedding them within the wall layers. This integration ensures the gel packs cannot be lost or misplaced while still providing effective cooling. The cooling function is combined with the container structure itself.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A collapsible insulated container has a base wall and a peripheral wall with an open end defining an enclosure. The peripheral wall has at least two layers and is divided into elongate pockets between the layers, with foldable crease lines between adjacent pockets. Each pocket contains a flexible-walled, insulating gel pack which substantially fills the pocket. The crease lines may be defined by stitching securing the outer and inner layers of the container together. The gel packs may be surrounded by matting, foam or mesh material which is sewn into the lines of stitching, or may have integral peripheral rims sewn into the lines of stitching. The container is foldable between an erect, open condition and a storage condition in which it is folded along the crease lines into a substantially flattened package.
