Canopy Roof Structure with Central Hub and Cantilever Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing canopy structures with automatic roof structures face a trade-off between increased headroom and stability, where higher, angled roof designs compromise the overall structural strength and stability.
Innovation Solution
A canopy design featuring a plurality of vertical support posts connected by trusses with roof support rods extending to a central hub, incorporating cantilever supports and central truss supports that provide enhanced stability and support for the canopy shell, maintaining increased headroom without compromising structural integrity.

Engineering Contradiction Analysis
1Length of stationary object
If a higher, angled roof structure is used to increase headroom, then head clearance is improved, but the overall structure's stability and strength decrease
Solution Approach 1:
The roof structure is segmented into multiple components: roof support rods extending from vertical posts to a central hub, central truss supports, and stubs. This segmentation allows each component to be optimized independently - the roof rods provide height and headroom while the central truss supports and stubs maintain structural stability through distributed load paths.
Solution Approach 2:
The patent introduces a vertical dimension to the roof support system by extending roof support rods from the vertical posts upward to a central hub, creating a three-dimensional roof structure. This dimensional change allows the roof to achieve greater height and head clearance while the central truss supports provide lateral stability through a different spatial arrangement.
2Strength
If X shaped trusses are used to provide support for the top cover, then structural support is improved, but the canopy has relatively low clearance
Solution Approach 1:
Instead of using horizontal X-shaped trusses that limit vertical clearance, the patent extends the support structure vertically by having roof support rods reach from the vertical posts to a central hub above. This vertical dimensionality change allows the roof to be higher while the central truss supports and stubs provide the necessary structural support for the top cover.
Solution Approach 2:
The central hub acts as an intermediary element that receives roof support rods from multiple vertical posts and transfers loads to the central truss supports and stubs. This intermediary structure enables the roof to achieve greater height and clearance while maintaining structural support through the distributed load path through the central hub and truss system.

AI summary
The technology of the present application provides a canopy with an automatic roof structure having improved structural stability. The canopy comprises a plurality of vertical support posts connected by trusses. A plurality of roof support rods extend from the vertical support posts to a central hub. At least one of the roof support rods has a cantilever support extending from the associated slide or thereabouts to a pivot on the roof support rod. The canopy also comprises central truss supports and stubs extending from the connection of the lateral trusses to the central hub. The canopy has an expanded, open configuration and a collapsed, closed configuration.
