Convertible Shipping Container with Strut Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard intermodal shipping containers are often transported empty from western markets back to eastern Asia, incurring significant fuel, time, and labor costs, and their conversion for alternative uses is hindered by unsuitable dimensions and functional design, making local modular construction more cost-effective.
Innovation Solution
A shipping container with an inner skin featuring parallel vertical strut channels for securing prefabricated structures and routing services, and a double skin structure with polyurethane foam insulation, allowing for efficient conversion into building units like site offices or accommodation, with removable panels and doors for versatile use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If standard shipping containers are transported empty from west to east, then container availability is maintained, but fuel costs and time consumption increase significantly
Solution Approach 1:
The container is designed with changeable parameters including removable doors and panels, and configurable internal strut channels that can be adjusted or removed. This flexibility allows the container to adapt to different uses (storage, conversion, disposal) depending on economic conditions, preventing unnecessary empty returns when local demand exists
2Loss of energy
If empty containers are resold locally for alternative purposes, then transportation costs are reduced, but conversion costs are high due to unsuitable dimensions and functional design
Solution Approach 1:
The container is pre-configured with vertical strut channels, removable doors, and panels during manufacturing. These features are prepared in advance to facilitate easy conversion into building units or storage structures, eliminating the need for costly post-acquisition modifications
Solution Approach 2:
The container design incorporates universal features such as standardized strut channels that can accommodate various fixings and configurations, removable doors and panels for different access requirements, and insulation layers suitable for multiple uses. This multi-functionality allows the same container base to serve different purposes (storage, accommodation, office) without requiring custom modifications
3Adaptability or versatility
If containers are designed for easy conversion, then local reuse becomes viable, but structural integrity during transport may be compromised
Solution Approach 1:
The container is segmented into modular components including removable doors, panels, and configurable strut channels. These segmented elements can be independently adjusted or removed for conversion purposes while the main container structure remains intact and structurally sound for transport
Solution Approach 2:
The container incorporates dynamic elements such as removable and configurable components that allow the structure to adapt to different uses. The strut channels can be positioned or removed as needed, and doors/panels can be exchanged, enabling the container to transition between states (transport mode vs. conversion mode) while maintaining structural integrity
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's design facilitates cost-effective conversion and reuse by maintaining structural integrity while reducing the need for costly modifications, enhancing insulation, and allowing for efficient modular design and installation of internal fit-outs, thus minimizing environmental impact and operational costs.
Implementation Method 1
The cavity may comprise an insulating material, and the insulating material may comprise polyurethane foam
