Deployable Cover With Roller And Sliding Rafters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deployable and retractable covers, such as pavilions and sheds, are cumbersome and complicated to assemble and disassemble, and their retraction and deployment processes are similarly inefficient.
Innovation Solution
A cover system comprising a cover sheet with four edges, flexible rafters slidably connected to opposite edges, and rollers on other edges that allow the cover sheet to wrap around and be released from the rollers based on the roller's direction of rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional covers are used to cover open spaces, then protection from sunlight and rain is provided, but assembly and disassembly becomes complicated and cumbersome
Solution Approach 1:
The cover system is divided into modular components: cover sheets, flexible rafters, and roller assemblies. Each component can be independently assembled and disassembled, transforming a complex monolithic structure into simple modular units that are easy to handle and install
Solution Approach 2:
The cover system incorporates dynamic elements including rollers that rotate to deploy/retract cover sheets, and flexible rafters that can bend and adapt. This dynamic design allows the cover to be quickly deployed by rotating rollers rather than complex manual assembly
2Reliability
If traditional covers are used, then coverage protection is achieved, but retraction and deployment processes are cumbersome and complicated
Solution Approach 1:
The roller assemblies enable dynamic deployment and retraction of cover sheets through simple rotation. The flexible rafters provide dynamic adaptability during deployment. This transforms the static cover into a dynamically adjustable system that can be quickly deployed or retracted by rotating rollers, dramatically reducing the time required compared to traditional manual assembly
Solution Approach 2:
The cover system is designed to be self-deploying through the roller mechanism. Once the rollers are positioned and rotated, the cover sheets automatically unroll and deploy without requiring additional manual assembly steps, reducing both time and operational complexity

AI summary
A cover system comprises at least one cover sheet having four edges and a plurality of flexible rafters. Each of the rafters is slidably connected to at least one of two opposite edges of the four edges, and at least one roller is provided on at least one of two other opposite edges of the four edges, wherein the roller is configured to rotate. The cover sheet is configured to wrap around the roller and be released from the roller, depending on a direction of rotation of the roller.
