Ground-Based Edge Protector Tool for Flatbed Tarp Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for placing and removing edge protectors and tarps on flatbed trailers are cumbersome, costly, and difficult to use, posing safety risks due to the need for users to climb onto the trailer.
Innovation Solution
A tool with a working head and elongated handle designed to facilitate the placement and removal of edge protectors and tarps from the ground, featuring a slot to frictionally hold edge protector sections and a convex dome shape to lift tarps off corners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a person climbs onto the flatbed trailer to install edge protectors, then the edge protectors can be properly positioned on the cargo, but the process becomes time-consuming and potentially hazardous
Solution Approach 1:
The patent introduces a mechanical tool as an intermediary device that enables ground-based installation of edge protectors. The tool includes a handle, a working end with clamping panels, and a positioning mechanism that allows the user to place edge protectors on cargo corners without climbing onto the trailer. This mediator transfers the installation capability from direct human contact (climbing) to remote operation (ground-based tool use).
Solution Approach 2:
The patent replaces the manual climbing and hand-placement mechanism with a mechanical tool system. The tool incorporates clamping panels with spring-loaded clamping-jaw means, a positioning mechanism, and a handle that leverages mechanical advantage to securely place edge protectors on cargo corners from ground level, substituting the need for human physical access to elevated surfaces.
2Ease of operation
If commercial tools are used to place edge protectors from the ground, then safety is improved, but the tools are complex and costly
Solution Approach 1:
The patent divides the tool into distinct functional segments: a handle for user grip and force application, a working end with clamping panels for securing the edge protector, and a positioning mechanism for accurate placement. This segmentation allows each component to be optimized for its specific function while keeping the overall design relatively simple and cost-effective.
Solution Approach 2:
Instead of having the edge protector attach to the tool and be lifted into place, the patent inverts the approach by having the clamping panels clamp the edge protector and then the entire assembly is positioned and released. This inversion simplifies the attachment mechanism and reduces the complexity of locking and releasing systems.
3Ease of operation
If existing tools are used to remove tarps from cargo, then the tarp can be removed from the ground, but the tools lack effectiveness at freeing tarps from cargo corners
Solution Approach 1:
The patent applies local quality by designing the working end of the tool with specific features tailored for corner engagement. The clamping panels and positioning mechanism are configured to specifically target and free tarps from cargo corners, where the majority of resistance occurs during removal. This localized optimization at the critical corner interface improves overall tarp removal efficiency without requiring complex modifications to the entire tool.

AI summary
A tool and method for installing and removing an edge protector on cargo of a trailer by a user standing on the ground and for removing a tarp on the cargo by the user standing on the ground. The tool includes a working head and an elongated handle. The working head is an elongated body having a longitudinal axis, a top end portion and a bottom end portion. The top end portion is rounded with at least a portion being of a convex shape. The elongated body includes a fixed size slot extending parallel to the longitudinal axis configured to receive and frictionally a portion the edge protector therein to install and remove the edge protector from the cargo. The elongated handle is connected to the bottom portion of the working head to manipulate the tool.
