Outdoor Shelter Canopy With Pocket Structure And Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional outdoor shelters require a significant amount of time to assemble due to complex installation processes of their roof canopies, and their corner portions are prone to tearing and stitching failure under stress.
Innovation Solution
A roof canopy design featuring a canopy fabric with integrated pocket structures and handle members that facilitate easier installation by allowing users to grasp and fit the canopy over roof frame members, with reinforced corner portions and stretchable fabric to reduce stress on stitching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional roof canopy design is used, then the canopy provides basic coverage, but the assembly time is excessive and corner portions are prone to tearing
Solution Approach 1:
The roof canopy is divided into multiple canopy panels that can be independently handled and installed. Each panel can be separately attached to roof frame members, allowing for modular assembly that reduces the time and complexity of installation compared to a single large canopy structure.
Solution Approach 2:
Grommets are pre-attached to the canopy panels during manufacturing before installation. This preliminary action eliminates the need for on-site grommet installation, significantly reducing assembly time and making the installation process easier for users.
2Strength
If conventional corner design is used, then the canopy structure is simple, but the corner portions are susceptible to tearing and stitching failure
Solution Approach 1:
The corner portions of the canopy panels are reinforced with additional material and stitching specifically at the high-stress corner regions. This local reinforcement strengthens the corners where tearing is most likely to occur without requiring complex structural changes throughout the entire canopy.
Solution Approach 2:
Reinforced corner stitching and additional material layers are built into the corner portions during manufacturing to preemptively strengthen these vulnerable areas. This beforehand cushioning prevents tearing and stitching failure before they can occur during installation or use.
3Reliability
If conventional attachment method is used, then the canopy can be installed, but the stitching experiences high stress and is likely to fail
Solution Approach 1:
Grommets are pre-attached to the canopy panels at the locations where roof frame members will be inserted. This preliminary attachment creates reinforced connection points that distribute stress away from the stitching, preventing stitching failure during installation and use.
Solution Approach 2:
Grommets serve as intermediary components between the canopy fabric and the roof frame members. These metal or plastic rings distribute the mechanical stress from the frame members across a larger area of the fabric, reducing the stress concentration on the stitching and preventing tearing.

AI summary
A roof canopy for an outdoor shelter is disclosed herein. The roof canopy includes a canopy fabric material configured to form a roof cover of an outdoor shelter; a pocket structure attached to a second surface of the canopy fabric material, the pocket structure including a pocket fabric sheet at least partially spaced apart from the canopy fabric material, the pocket fabric sheet and the canopy fabric material together defining a pocket cavity configured to receive an end portion of a roof frame member of the outdoor shelter therein; and a handle member attached to a first surface of the canopy fabric material, the handle member overlapping at least a portion of the canopy fabric material that partially defines the pocket cavity, the handle member configured to be grasped by a user so as to facilitate the pocket structure being fitted over the end portion of the roof frame member.
