Convertible Tarp Guide Track and Trolley Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing convertible tarp systems for flatbed trailers are cumbersome to remove for side access, as they lack efficient mechanisms for longitudinal and lateral movement, making it difficult to handle freight effectively.
Innovation Solution
A convertible tarp system featuring improved guide tracks with a C-shaped channel and trolley assemblies, including support rollers, intermediate rollers, and guide rollers, which allow for secure longitudinal movement and lateral support of bows, enabling easy retraction and extension of the tarp for enclosed cargo spaces with variable volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional tarp systems use bows and support structures to create an enclosed space, then cargo protection is improved, but the structure becomes difficult and cumbersome to remove for side access
Solution Approach 1:
The tarp system transitions from a static enclosed structure to a dynamic, movable configuration. The guide track and trolley assembly enable the tarp to be easily repositioned along the trailer length, allowing quick access for loading and unloading while maintaining protection when enclosed.
Solution Approach 2:
The tarp system is divided into segments that can move independently along the guide track. The trolley assembly acts as a separate movable component that carries the tarp, allowing the protective covering to be detached or repositioned without moving the entire trailer structure.
2Ease of operation
If the tarp system is designed to be easily removable for access, then ease of operation is improved, but the structural stability and enclosure may be compromised
Solution Approach 1:
The guide track serves as an intermediary structure that provides stable support for the movable tarp system. The track is securely mounted to the trailer, providing a stable foundation that allows the tarp to move freely while maintaining overall structural integrity.
Solution Approach 2:
The tarp and trolley assembly can be completely removed from the guide track when not needed, separating the protective covering from the trailer structure. This allows full access to the trailer sides while the guide track remains as a stable, permanent fixture.
3Stability of the object's composition
If the tarp system uses complex support structures to maintain enclosure, then enclosed space stability is improved, but device complexity increases
Solution Approach 1:
The complex mechanical support structures are replaced with a simpler guide track and trolley system. The guide track provides structural support through its mounting to the trailer, while the lightweight trolley assembly enables tarp movement without requiring complex mechanical mechanisms.
Solution Approach 2:
The tarp itself acts as a flexible protective shell that maintains the enclosed space when stretched over the bows. This flexible membrane provides sufficient enclosure and protection without requiring rigid, complex structural frameworks.

AI summary
A convertible tarp system provides an extendable and retractable enclosure especially suited for covering a flatbed trailer. The convertible tarp system includes a plurality of bows and trolleys that support a tarp structure. A guide track defines a longitudinal path of movement and supports the trolleys for movement along the longitudinal path. The guide track is configured to substantially restrict lateral movement of the trolleys along the longitudinal path.
