Solution Overview

Problem

Current stackable and nestable containers lack an efficient thermal management system that allows for both stacking and nesting configurations while maintaining effective thermal insulation and compact storage.

Innovation Solution

The introduction of a foldable thermal insert made from thermally active or passive materials, such as polyurethane foam or reflective metallic sheeting, which can be unfolded for stacking and folded for nesting, allowing for efficient thermal regulation and compact storage by being placed between containers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rigid thermal insulation system is used in stackable containers, then thermal insulation effectiveness is improved, but storage volume efficiency deteriorates when containers need to be nested

Engineering Contradiction:
Improvethermal insulation effectivenessVSAvoidstorage volume efficiency
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The thermal insulation system is designed to be dynamic rather than static. The insulation panels can be folded or collapsed when not needed, allowing the container to be nested compactly. When stacking is required, the insulation panels are deployed to provide full thermal protection. This dynamic configuration resolves the contradiction between maintaining thermal insulation effectiveness and achieving compact storage volume.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The thermal insulation system is divided into separate, modular panels that can be independently folded or collapsed. This segmentation allows the insulation structure to be broken down into compact segments for nesting, while still providing complete thermal coverage when assembled in the stacked configuration. Each segment can be stored efficiently without compromising the overall insulation performance.

Inventive Principle:
Principle #1Segmentation

2Temperature

If thermal insulation materials are added to containers, then temperature stability is improved, but device complexity increases

Engineering Contradiction:
Improvetemperature stabilityVSAvoiddevice complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The container structure is designed to serve multiple functions: the same structural elements that provide container integrity also serve as the thermal insulation framework. The foldable panels perform both structural support and thermal insulation functions, eliminating the need for separate, complex insulation systems. This multi-functionality reduces overall device complexity while maintaining temperature stability.

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

Solution Approach 2:

The patent employs flexible thermal insulation panels that can be folded and collapsed, rather than rigid insulation structures. These flexible panels provide effective thermal protection when deployed but can be compacted to minimal thickness when not needed. This approach maintains temperature stability without adding significant structural complexity or bulk to the container design.

Inventive Principle:
Principle #30Flexible shells and thin films

3Volume of moving object

If containers are designed for nesting configuration, then storage efficiency is improved, but thermal insulation capability deteriorates

Engineering Contradiction:
Improvestorage efficiencyVSAvoidthermal insulation capability
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The container system dynamically switches between nested and stacked configurations based on operational needs. When containers are nested for storage or transport, the insulation panels are folded or collapsed to minimize volume. When containers are stacked for use, the insulation panels are deployed to provide full thermal protection. This dynamic transformation allows the system to optimize both storage efficiency and thermal insulation capability at different times without compromise.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements a nesting mechanism where containers can be placed inside one another in a compact configuration. The thermal insulation panels are designed to fold or collapse during nesting, allowing the containers to achieve minimal storage volume. When needed, the panels are unfolded or expanded to restore full thermal insulation capability, effectively resolving the contradiction between nesting efficiency and insulation performance.

Inventive Principle:
Principle #7Nested doll (Nesting)
