Backpack Integrated Canopy Deployment System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional umbrellas require users to hold them with one hand, limiting their ability to maintain the umbrella's position and orientation, especially in windy or rainy conditions, as they occupy a hand and demand mental and physical effort.
Innovation Solution
A portable canopy deployment system integrated into a backpack with a user-actuated mechanism that allows hands-free deployment and control of the canopy, featuring a waterproof polymer fabric, expandable ribs, and a central rod with a release switch for easy positioning without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional handheld umbrella is used, then the user can provide protection from rain or sun, but the user must occupy at least one hand to hold and stabilize the umbrella, reducing ease of operation
Solution Approach 1:
The patent combines the umbrella canopy with a backpack, merging two separate functions (protection from elements and carrying belongings) into a single integrated system. The canopy is stored within and deployed from the backpack structure, allowing the user to have both protection and carrying capacity without needing separate devices.
Solution Approach 2:
The canopy system is designed to deploy and stabilize automatically without requiring manual holding. The mechanical deployment mechanism and attachment system allow the canopy to self-position and maintain stability, freeing the user's hands for other tasks while maintaining protective function.
2Reliability
If a traditional handheld umbrella is used, then the user can provide protection from elements, but the user must expend mental and physical effort to maintain the umbrella in the proper position, especially in windy conditions
Solution Approach 1:
By integrating the canopy attachment system with the backpack structure, the patent creates a stable mounting system that distributes forces across the backpack frame rather than requiring the user to counteract all forces with hand strength. The backpack serves as both carrier and support structure.
Solution Approach 2:
The patent employs curved or arched structural elements in the canopy frame and support ribs that provide inherent structural strength and stability. These curved structures better distribute mechanical loads and resist deformation from wind forces compared to straight rigid elements.
3Area of stationary object
If a traditional handheld umbrella is used, then the user can provide localized protection, but the small radius and handheld design limit the area of protection and require constant adjustment
Solution Approach 1:
The patent employs a deployable and adjustable canopy structure that can change its configuration based on user needs. The canopy can be deployed to provide protection, adjusted to different positions, and collapsed when not needed, all through a mechanical system integrated with the backpack.
Solution Approach 2:
The canopy structure is divided into multiple segments including ribs, panels, and support elements that can independently adjust or fold. This segmentation allows the canopy to maintain a larger protected area while remaining compact when stored in the backpack.

AI summary
A canopy deployment system provides a user with hands free use of a canopy while obtaining protection from elements. The deployment system integrates with a backpack that fastens to the user. The system controllably holds the canopy, and the user orients the canopy to a desired direction and angle without the use of hands. The user controls the orientation of the canopy by bending, twisting, and swiveling. The canopy is supported by a frame. The frame joins with a central rod. A ring moves along the central rod to release or restrict the frame, and thereby enable a deployed position and a collapsed position. A canopy container contains the canopy and central rod. A deploy cord and a collapse cord extend from the canopy container to actuate the deployed and collapsed positions. The canopy container positions inside a carry container, like a backpack that attaches to a user.
