Reusable portable shipping container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable shipping containers fail to maintain temperature-sensitive goods at desired temperatures during transport, often leading to product degradation and waste, and are typically single-use, contributing to environmental waste.
Innovation Solution
A reusable portable shipping container with a modular design, featuring a container body with a payload chamber, a pivotally or slidably coupled lid, an inner lid assembly with movable doors, and integrated thermal mass or phase change material for temperature control, along with an electronic display screen and a detachable tablet for monitoring and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If single-use containers (cardboard, Styrofoam) are used, then manufacturing cost is low, but environmental waste increases and reusability is lost
Solution Approach 1:
The container is designed for multiple reuse cycles with durable materials (polypropylene or polyethylene) instead of single-use materials. The container can be returned and reused, eliminating the need to discard after one use and reducing environmental waste while maintaining manufacturing feasibility
Solution Approach 2:
The container uses composite construction with insulating material layers (such as foam insulation) combined with durable structural materials (polypropylene or polyethylene), creating a reusable container that maintains thermal performance while being environmentally sustainable through multiple uses
2Temperature
If ice is used for cooling, then cooling effect is achieved, but ice melts and soaks products requiring emptying
Solution Approach 1:
The container uses phase change material (PCM) packs instead of regular ice. These PCM packs undergo phase transition at controlled temperatures to maintain cooling effect without melting into uncontrolled liquid that would soak products. The PCM is encapsulated to contain any liquid while maintaining cooling performance
Solution Approach 2:
The PCM packs act as an intermediary between the cooling requirement and the products. Instead of direct ice contact that causes soaking, the PCM packs provide controlled thermal energy transfer while containing any phase change liquid, preventing product contamination
3Ease of operation
If existing coolers are used for long-distance transport, then portability is maintained, but temperature maintenance capability is lost
Solution Approach 1:
The container incorporates multiple layers including insulating material (such as foam insulation) between the outer shell and inner chamber. This composite structure provides enhanced thermal insulation that maintains temperature during extended transport periods while keeping the container lightweight and portable
Solution Approach 2:
The PCM packs are designed with specific phase transition temperatures matched to the required product storage temperature. During long-distance transport, these PCM packs absorb and release thermal energy during phase transitions, actively maintaining temperature stability beyond what passive insulation alone could achieve
4Loss of substance
If reusable containers are designed, then environmental waste is reduced, but return difficulty increases due to user inaction
Solution Approach 1:
The container includes an electronic display screen that provides real-time feedback to users about temperature maintenance status, shipping information, and return instructions. This feedback mechanism keeps users informed and engaged, reducing inaction and improving return rates by making the return process transparent and straightforward
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 container effectively maintains temperature-sensitive goods within a desired temperature range, reduces waste through reusability, and enhances logistics with real-time monitoring and automated shipping label updates.
Implementation Method 1
a pack of thermal mass or phase change material disposed proximate the one or more doors and configured to be disposed over the one or more goods in the payload chamber

AI summary
A reusable shipper container has a container body with a payload chamber for holding goods and a lid operable to access the payload chamber. The reusable shipper container also has a tablet display screen detachably coupled to the container body. The reusable shipper container also has an inner lid assembly with one or more doors selectively movable between a first position over the payload chamber to close the payload chamber, and a second position to allow access to the payload chamber. The reusable shipper container can have a display screen on an underside of the lid that can auto-display information or autoplay videos, for example, when the lid is open and/or the shipper container has arrived at its destination.
