Rolling Tarp Bow Tensioning for Faster Trailer Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of rolling tarp systems on flatbed trailers is inefficient due to the manual processes of positioning and tensioning bows and tarps, which can delay shipping schedules.
Innovation Solution
A motorized deployment system with tensioning assemblies and roller assemblies that automate the positioning and tensioning of bows along the trailer, using actuators and motors to move the bows and tension the tarp, allowing for quicker and more efficient deployment and retraction of the tarp system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual processes are used for positioning and tensioning bows and tarps, then the system structure remains simple, but the deployment time increases and shipping efficiency decreases
Solution Approach 1:
The patent replaces manual mechanical operations with an automated control system. A controller receives signals and automatically controls the tensioning assemblies to adjust tarp tension and the roller assemblies to position bows, eliminating the need for manual positioning and tensioning operations while significantly reducing deployment time
Solution Approach 2:
The system enables automated self-service deployment through the controller that autonomously manages the entire deployment process. The controller automatically coordinates the tensioning assemblies and roller assemblies to deploy and retract the tarp system without requiring manual intervention, thereby improving productivity while maintaining manageable system complexity through integrated control
2Loss of time
If automated tensioning assemblies and roller assemblies are implemented, then deployment time is reduced, but the device complexity increases
Solution Approach 1:
The controller serves multiple functions by managing both the tensioning assemblies for tarp tension adjustment and the roller assemblies for bow positioning. This multi-functional approach consolidates control operations into a single device, reducing deployment time while preventing excessive system complexity through functional integration
Solution Approach 2:
The patent combines the control functions for tensioning and positioning operations into a single integrated controller. By merging these control functions, the system achieves automated deployment that reduces time loss while maintaining manageable complexity through unified control architecture

AI summary
A rolling tarp deployment system includes a trailer, a bulkhead fixed to the trailer, first and second bows movable along the trailer, first and second tensioning assemblies, and a cover. The first tensioning assembly has a first member secured to the first bow, a second member secured to the bulkhead, and a first actuator configured to engage the first and second members to restrain the first bow to the bulkhead. The second tensioning assembly has a third member secured to the second bow, a fourth member fixed to the trailer, and a second actuator configured to engage the third and fourth members and move the second bow away from the bulkhead. The cover is tensioned when both the first and second members and the third and fourth members are engaged.
