Solution Overview

Problem

Existing insulated shipping containers for temperature-sensitive materials face issues with insulation material leakage and non-recyclable components, which can damage perishables and complicate waste management due to the use of mixed materials like cardboard and plastic.

Innovation Solution

A cartridge assembly comprising inner and outer half-slotted containers with a flange coupling, filled with recyclable organic fiber insulation, ensuring a tight seal and preventing insulation leakage, and a shipping container design that is entirely curbside recyclable without material separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional insulated shipping containers are used, then temperature control is achieved, but insulation material leakage occurs and recyclability is compromised

Engineering Contradiction:
Improvetemperature control stabilityVSAvoidinsulation material leakage
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The container is divided into inner and outer containers with distinct functions. The inner container holds the payload while the outer container provides insulation containment. This segmentation prevents insulation material from contacting and potentially damaging the payload, while maintaining temperature control stability through the insulated plenum space.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A flange structure acts as an intermediary element between the inner and outer containers. This flange provides a sealed interface that contains the insulation material within the plenum space, preventing leakage while allowing the insulation to perform its thermal control function. The flange effectively mediates between the payload containment need and insulation containment requirement.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If mixed materials (cardboard and plastic) are used in shipping containers, then insulation performance is improved, but recyclability is compromised

Engineering Contradiction:
Improveinsulation performanceVSAvoidrecyclability
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The container system is segmented into distinct components (inner container, outer container, flange) that can be manufactured from different materials optimized for their specific functions. This allows the outer container to use insulating materials while the inner container and flange can be designed for recyclability, resolving the conflict between insulation performance and recyclability by separating these concerns into different components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flange and inner container are designed to be made from homogeneous recyclable materials, while the outer container can use heterogeneous insulating materials. This material homogeneity in critical components facilitates recyclability, while material diversity in the insulation layer maintains thermal performance, allowing both requirements to be satisfied through strategic material selection in different parts of the system.

Inventive Principle:
Principle #33Homogeneity

AI summary

A cartridge assembly for transporting temperature-sensitive materials includes an inner half-slotted container for housing the temperature-sensitive materials and an outer half-slotted container containing the inner half-slotted container. Each of the inner half-slotted container and the outer half-slotted container includes an open, flapless proximal end and a sealable distal end. A flange couples the inner half-slotted container to the outer half-slotted container.
