Convertible Cargo Floor Tray for Fast Bulk-Container Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cargo transport containers struggle to efficiently switch between containerized and bulk cargo modes due to the need for extensive modifications or complete replacement of the cargo floor, which is time-consuming and labor-intensive, and the weight and space constraints in transportation vehicles make simultaneous installation of components impractical.
Innovation Solution
A convertible cargo handling system with a universal adapter tray and modular components that can be easily installed or removed, allowing quick transitions between cargo modes, incorporating features like roller tracks for containerized cargo and a smooth floor for bulk cargo while maintaining structural integrity and compatibility with existing structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cargo floor includes roller tracks and handling components for containerized cargo, then containerized cargo handling efficiency is improved, but the floor becomes obstructed and unsuitable for bulk cargo loading
Solution Approach 1:
The cargo floor system is divided into modular components: a base floor structure and removable roller track assemblies. The roller tracks are segmented into discrete sections that can be independently installed or removed, allowing the floor to be reconfigured for different cargo types without replacing the entire floor system.
Solution Approach 2:
The cargo floor system transitions from a static configuration to a dynamic one where roller tracks can be quickly installed and removed. This dynamic reconfiguration capability allows the same floor to adapt between containerized cargo mode (with rollers) and bulk cargo mode (without rollers), resolving the contradiction between specialized handling and general compatibility.
2Adaptability or versatility
If the cargo floor is configured with a smooth surface for bulk cargo, then bulk cargo loading is facilitated, but containerized cargo handling equipment cannot be installed
Solution Approach 1:
The base floor is pre-configured with a smooth surface and integrated mounting structures that prepare the system for future roller track installation. This preliminary preparation allows rapid deployment of containerized cargo handling capabilities when needed, without requiring extensive modifications to the floor structure at that moment.
Solution Approach 2:
The base floor structure serves multiple functions: it provides a smooth loading surface for bulk cargo and simultaneously contains integrated mounting points for roller tracks needed for containerized cargo. This multi-functional design eliminates the need for separate floor configurations for different cargo types.
3Adaptability or versatility
If extensive modifications or complete replacement of the cargo floor are performed to switch between cargo modes, then cargo handling capability is improved, but reconfiguration time and labor requirements increase significantly
Solution Approach 1:
The roller track system is divided into modular sections that can be independently installed or removed using standardized connection mechanisms. This segmentation reduces reconfiguration time by allowing quick assembly and disassembly without requiring complete floor replacement or extensive modifications.
Solution Approach 2:
The floor system incorporates dynamic reconfiguration capabilities through quick-connect mechanisms and removable components. This allows the cargo handling system to adapt between modes rapidly, transforming what would be a time-consuming replacement operation into a quick reconfiguration task.
4Adaptability or versatility
If components for both cargo modes are permanently installed simultaneously, then both cargo types can be accommodated, but weight and space constraints in transportation vehicles are exceeded
Solution Approach 1:
The cargo handling system is segmented into essential permanent components (base floor with mounting points) and optional removable components (roller track assemblies). This segmentation allows the vehicle to carry only the necessary components for each specific cargo type, reducing overall weight while maintaining dual-mode capability when components are combined.
Solution Approach 2:
The roller track assemblies are designed to nest within or attach to the base floor structure, maximizing space utilization. When not in use, removable components can be stowed efficiently, minimizing the space and weight penalty of maintaining dual-mode capability without permanently installing all components.

AI summary
A cargo handling assembly for a transport container includes an adapter tray configured to fit within a gap between floor panels of the transport container, the adapter tray comprising a lower wall and side walls forming a recessed gutter. An anchor plate is attachable to the lower wall of the adapter tray. A roller tray is configured to nest within the recessed gutter of the adapter tray, the roller tray comprising an anchor block for attachment to the anchor plate. A tray cover is insertable into the recessed gutter when the roller tray is removed, the tray cover configured to span between the side walls of the adapter tray.
