Backpack Umbrella Stabilizing Unit Preventing Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional back-mounted umbrellas are difficult to attach, prone to rotation and tilting in strong winds, and require cumbersome harnesses that restrict movement and are not easily convertible between worn and handheld use.
Innovation Solution
A universal anchoring device that includes a collapsible umbrella with a straight center shaft and a stabilizing unit that can be securely attached to any carrier bag or backpack, providing adjustable support to stabilize the umbrella against rotation and tilting, while allowing easy conversion between worn and handheld modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a harness is used to secure the umbrella to the back, then the umbrella can be worn hands-free, but the harness is cumbersome and restrictive
Solution Approach 1:
The stabilizing unit is designed to be universally applicable to multiple bag sizes and types (small, medium, large, kids, women, men sizes) through an adjustable strap system. The same basic structure adapts to different carrier bag dimensions, eliminating the need for multiple specialized harness designs.
Solution Approach 2:
The stabilizing unit is divided into separate functional components: an adjustable strap system for attachment to carrier bags, a vertical support structure for positioning, and a holder for securing the umbrella. This segmentation allows each component to be optimized independently while maintaining overall simplicity.
2Reliability
If a specialized harness is used to mount the umbrella, then the umbrella can be secured to the back, but it is difficult to attach and restrictive
Solution Approach 1:
The stabilizing unit serves multiple functions: it secures the umbrella to the back, can be attached to various carrier bag sizes, and provides adjustable positioning. This multi-functionality reduces the need for specialized attachment mechanisms for different scenarios.
Solution Approach 2:
The strap system incorporates adjustability, allowing the user to dynamically modify the fit and positioning of the stabilizing unit on their body and on different bag sizes. This dynamic adjustment simplifies attachment while maintaining security.
3Ease of operation
If the umbrella is mounted to the back, then hands are freed for other tasks, but the umbrella rotates and tilts in strong winds
Solution Approach 1:
The stabilizing unit extends vertically from the carrier bag to provide support in the vertical dimension, preventing the umbrella from rotating and tilting. The vertical orientation of the support structure creates stability against wind forces that would otherwise cause rotational movement.
Solution Approach 2:
The adjustable strap system is pre-configured to attach to the carrier bag before the umbrella is mounted, creating a stable base structure that prevents rotation and tilting before the umbrella is even attached to the stabilizing unit.
4Ease of operation
If a harness is used to wear the umbrella, then it can be carried without hands, but it must be detached for handheld use
Solution Approach 1:
The system is segmented into detachable components: the stabilizing unit that attaches to the carrier bag and the umbrella holder that can be easily removed. This allows the user to detach only the umbrella holder for handheld use while leaving the stabilizing unit attached to the bag for future hands-free carrying.
Solution Approach 2:
The attachment mechanisms use dynamic, reversible connections that allow easy transition between worn and handheld states. The adjustable straps and removable holder enable quick reconfiguration without complex detachment procedures.
