Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals carrying backpacks often struggle to manage umbrellas during rainy or sunny weather as they lack a hands-free solution to hold the umbrella while keeping their hands free for other items.
Innovation Solution
A backpack strap umbrella holder that securely attaches to the backpack strap, adjustable to fit various umbrella poles and straps, using a hinged panel structure with thumb screws and a U-shaped channel to retain the umbrella pole, allowing for hands-free use and easy attachment/detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a person carries a backpack and holds an umbrella, then they can be protected from rain or sun, but they cannot have their hands free for other items
Solution Approach 1:
The umbrella holder is divided into multiple hinged panels (first panel, second panel, third panel) that can be independently positioned and adjusted. This segmentation allows the holder to adapt to different strap widths and umbrella pole sizes while maintaining a relatively simple overall structure that attaches to the backpack strap.
Solution Approach 2:
The umbrella holder is designed with adjustable features including hinged panels and thumb screws that allow it to accommodate various umbrella pole diameters and backpack strap widths. This multi-functionality enables a single device to serve different users and different umbrella types without requiring multiple specialized holders.
2Adaptability or versatility
If an umbrella holder is designed to fit various umbrella poles and backpack straps, then adaptability is improved, but device complexity increases
Solution Approach 1:
The holder incorporates hinged connections between panels that allow dynamic adjustment of the holder's shape and size. The thumb screws provide adjustable fastening that can accommodate different strap widths. This dynamic structure enables the holder to adapt to various umbrella and strap configurations without requiring a completely different design for each case.
Solution Approach 2:
The hinged panel structure allows the holder to collapse or nest into a compact form when not in use, while expanding to accommodate larger umbrellas or wider straps when needed. The nested capability reduces the holder's profile during storage while maintaining adaptability during use.
3Reliability
If an umbrella holder securely attaches to the backpack strap, then reliability is improved, but ease of manufacture decreases
Solution Approach 1:
The thumb screw mechanism allows the user to easily tighten and secure the holder to the backpack strap without requiring special tools or complex assembly procedures. The self-fastening capability provides reliable attachment while simplifying the manufacturing process compared to precision-machined fastening systems.
Solution Approach 2:
The holder panels appear to be made from relatively thin, easily formable materials that can be manufactured using simple processes such as bending, cutting, and joining. This approach to material selection and structural design improves ease of manufacture while maintaining sufficient strength and rigidity for secure attachment.

AI summary
An umbrella holder for supporting an umbrella pole on a backpack strap so that the wearer of the backpack can be in a hands-free condition while the umbrella is deployed. The device includes a first panel, a second panel, a third panel, a pair of thumb screws and a panel closure member. The first panel is hinged to the second panel. The second panel is hinged to the third panel. The first and second panels create a retaining space for a backpack strap. The second and third panels create a retaining space for an umbrella pole. The thumb screws are hinge and tightened to secure a backpack strap. The second and third panels are held together by the panel closure member which is attached by a hinge to the first panel. A preferred embodiment includes rubber cushion members to securely hold umbrella poles of varying diameters.
