Inflatable Tarp Deployment for Oversize Flatbed Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for covering large objects with flexible materials, such as tarps, are strenuous, time-consuming, and often dangerous, especially when dealing with oversize loads, and they often restrict the size and shape of cargo that can be transported due to the use of rigid structures and the need for dedicated space or forklifts.
Innovation Solution
An inflatable system that allows sheets of flexible material to be quickly and easily deployed over objects by inflating the inflatable within the furled tarp assembly, rolling it over the object, and then deflating it for storage, which can be done from the ground and requires minimal space, allowing for the coverage of objects of any size or shape without the need for a forklift.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rigid bows traveling on fixed tracks are used to enclose tarps, then tarping can be done quickly and safely, but the flatbed cannot transport oversize loads
Solution Approach 1:
The patent replaces rigid bows with dynamic, flexible alternatives that can adapt to different cargo configurations. The inflatable archway system can be inflated to provide structural support during tarping operations and then deflated to clear the way for oversize loads, transforming a static rigid structure into a dynamic adaptable one.
Solution Approach 2:
The patent changes the physical state of the support structure from rigid and fixed to inflatable and variable. By controlling the inflation/deflation parameters of the archway, the system can transition between providing structural support for rapid tarping and clearing the path for oversize cargo transport.
2Manufacturing precision
If overhead tarping systems are used, then tarps can be positioned accurately, but they require substantial dedicated space and forklifts
Solution Approach 1:
The patent uses an inflatable archway system that can be positioned and secured without requiring substantial dedicated storage space or forklifts. The inflatable structure provides the necessary support and positioning accuracy while being compact when deflated, eliminating the need for large storage areas and heavy equipment.
Solution Approach 2:
The patent replaces the mechanical forklift-based overhead tarping system with an inflatable archway system that can be manually positioned and secured. This substitution eliminates the need for expensive forklift equipment and substantial dedicated storage space while maintaining tarp positioning accuracy.
3Productivity
If rigid arch structures are permanently attached to the trailer, then tarping can be performed efficiently, but oversize loads cannot be transported
Solution Approach 1:
The patent replaces permanently attached rigid arch structures with a portable inflatable archway system. The inflatable arch can be set up efficiently for tarping operations and then collapsed and removed to accommodate oversize loads, providing both tarping efficiency and cargo dimension flexibility.
Solution Approach 2:
The patent uses an inflatable archway made of flexible material that can be inflated to provide structural support during tarping and then deflated to be stored or moved aside. This flexible shell approach replaces rigid permanent structures, enabling both efficient tarping and transport of oversize cargo.
4Device complexity
If manual tarping methods are used, then equipment costs are minimized, but the process is strenuous, time-consuming and dangerous
Solution Approach 1:
The patent divides the tarping process into manageable segments using a portable inflatable archway system that can be set up, used, and stored in discrete steps. This segmentation allows workers to perform tasks from the ground rather than climbing onto cargo, reducing physical strain and danger while maintaining equipment simplicity.
Solution Approach 2:
The patent introduces an inflatable archway as an intermediary structure that facilitates tarping operations. This intermediary provides a stable working platform and support structure, making the process easier and safer while avoiding the need for complex permanent installations or heavy machinery.

Function Achieved in This Case
This solution enables safe, quick, and efficient tarping of oversize loads with minimal effort, reducing the risk of injury and allowing for the transportation of cargo of any size or shape, while also being lightweight, inexpensive, and requiring minimal storage space.
Implementation Method 1
The inflatable is pressurized with a gas and rolled so as to unfurl at least a portion of the sheet of flexible material onto at least a portion of the object to be covered

AI summary
A sheet of flexible material can be deployed or stored by unfurling or furling the sheet using one or more inflatables. After the sheet is deployed to, for example, cover a load on a flatbed trailer, the inflatable can be deflated for storage. A sheet that has been removed from the load can be stored by placing an inflatable along an edge of the sheet. The inflatable is pressurized, and the sheet is furled onto the inflatable by rolling the inflatable. The inflatable is deflated and rolled up with the sheet for storage.
