Rolling Tarp Enclosure Rear Locking and Tensioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rolling tarp enclosure systems for flatbed trailers face limitations in tensioning mechanisms, particularly at the rear end, which can lead to uneven tension, reduced durability of wheels, and increased complexity in installation and operation, while also requiring additional components for drop deck trailers, increasing costs and interfering with system movements.
Innovation Solution
The system introduces improved rear locking and tensioning mechanisms that allow for easier and safer adjustment, enhanced durability, and simplified construction, including a movable rail system for drop deck trailers that eliminates the need for extra rail sections and carriages, along with lightweight and cost-effective modifications to support bows and wheeled carriages, and additional load securing mechanisms that minimize cargo space reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tensioning mechanisms are used at the rear end, then the tarp can be tensioned, but the tension is uneven and the wheels suffer reduced durability
Solution Approach 1:
The patent applies the dynamics principle by making the rear rail movable rather than fixed. The rear rail can move horizontally along the rear support structure, allowing the tensioning mechanism to dynamically adjust the tarp tension distribution. This movement capability enables the system to achieve uniform tension across the tarp while preventing excessive concentrated forces on the wheels, thereby improving both tension uniformity and wheel durability.
2Adaptability or versatility
If additional rail sections and carriages are added for drop deck trailers, then the system can accommodate different deck levels, but the complexity and cost increase
Solution Approach 1:
The patent applies the universality principle by designing a single, multi-functional rail system that can accommodate both standard flatbed trailers and drop deck trailers. The rear rail assembly is designed to be adjustable and adaptable to different deck configurations without requiring separate rail sections or additional carriages. This universal design reduces system complexity while maintaining versatility across different trailer types.
3Reliability
If conventional locking mechanisms are used, then the tarp can be secured, but the adjustment process is complex and time-consuming
Solution Approach 1:
The patent applies the mechanics substitution principle by replacing complex manual mechanical locking mechanisms with a simpler system. The rear rail incorporates a streamlined locking mechanism that can be easily engaged and disengaged, reducing the number of steps and components involved in the adjustment and securing process. This substitution maintains reliable tarp securing while significantly improving ease of operation and reducing adjustment time.

AI summary
A movable, tarp enclosure system includes a movable carriage having a main body and plural primary support wheels connected to the main body, at least one of the wheels being disposed at a first vertical level and at least one of the wheels being disposed at a being vertical level. The system also includes a support rail having a first and second support walls, the upper surfaces of which are respectively engaged by the carriage wheel(s) disposed at the first vertical level and at the second vertical level for movably supporting the movable carriage on the support rail.
