Rolling Tarp Locking System with Cam Plate and Motorized 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 delays shipping times and 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 motorized roller assemblies to move and secure the tarp sections, and a locking system with cam plates and arms to secure the bows in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual processes are used for positioning and tensioning bows and tarps, then the system structure remains simple, but deployment time increases and shipping schedules are delayed
Solution Approach 1:
The patent replaces manual mechanical operations with an automated motorized system. Motors are integrated into the roller assemblies to automatically position bows along the trailer, and actuators are incorporated into tensioning assemblies to automatically tension the tarp. This substitution of manual labor with motorized automation directly reduces deployment time while accepting increased system complexity through the addition of motors, actuators, and control systems.
2Productivity
If motorized roller assemblies and tensioning assemblies are added to automate deployment, then deployment speed increases, but device complexity and initial setup time increase
Solution Approach 1:
The patent merges the motorization function directly into the existing roller assemblies and tensioning assemblies. Rather than adding separate automated systems, the motors are integrated into the roller assemblies that already exist for bow positioning, and actuators are integrated into the tensioning assemblies. This merging approach increases productivity by automating deployment while minimizing the increase in perceived system complexity by combining functions into existing structural elements.
3Manufacturing precision
If actuators are used to engage members and restrain bows, then tensioning consistency improves, but device complexity increases
Solution Approach 1:
The actuators in the tensioning assemblies are designed to automatically engage members and restrain bows without requiring manual intervention. The system performs its own tensioning operation autonomously - when deployed, the actuators automatically engage the members to apply consistent tension to the tarp and restrain the bows in their proper positions. This self-service capability ensures consistent tensioning while the complexity is managed by making the system autonomous rather than requiring complex manual procedures.

AI summary
A rolling tarp locking system comprising a bow including a cam plate defining a cam profile having a proximal end and a distal end; and a locking assembly including an arm configured to move between a locked position and an unlocked position, the arm having a follower configured to move relative to the cam profile of cam plate from the proximal end and to the distal end such that when the arm moves from the unlocked position to the locked position the bow is pulled toward the locking assembly to a fixed position.
