Backpack Umbrella Anchoring Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional back-mounted umbrellas are difficult to attach and detach, prone to rotational and tilting movements, especially in windy conditions, and restrict hand use due to cumbersome harnesses, while also lacking convenient storage and stabilization.
Innovation Solution
A backpack and umbrella combination featuring a collapsible canopy with a straight center shaft and anchoring structure that securely engages within a tubular receiver, incorporating stabilizing bars to prevent rotational and tilting movements, allowing easy attachment and detachment, and providing a flexible handle for hand-held use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional back-mounted umbrellas use a harness to secure the umbrella, then the umbrella can be worn hands-free, but the harness is clumsy and restricts hand use while being difficult to attach and detach
Solution Approach 1:
The invention divides the back-mounted umbrella system into separate functional components: a simple backpack with a dedicated compartment and a separate anchoring structure that attaches to the backpack. This eliminates the need for a complex integrated harness while achieving the same hands-free carrying function.
Solution Approach 2:
The invention extracts the anchoring function from the umbrella itself and places it in a separate anchoring structure that attaches to the backpack. This allows the umbrella to be stored in the backpack compartment while the anchoring structure provides the mounting function, simplifying both the umbrella and the carrying system.
2Ease of operation
If prior back-mounted umbrellas use a simple holding structure, then the umbrella can be easily attached, but the umbrella rotates and tilts uncontrollably in wind and during walking
Solution Approach 1:
The anchoring structure incorporates a dynamic locking mechanism that allows the umbrella to be securely fixed in position, preventing rotation and tilting movements while maintaining ease of attachment and detachment. The locking mechanism adapts to provide stability without restricting the user's movement.
3Reliability
If a specialized harness is used to mount the umbrella on the back, then the umbrella can be secured, but the harness is difficult to emplace and serves no other useful purpose
Solution Approach 1:
The invention uses a standard backpack as the mounting base, which serves multiple purposes: it can carry the umbrella when not in use, store other personal items, and provide a stable platform for the anchoring structure. This eliminates the need for a specialized single-purpose harness while maintaining reliable umbrella securing.
4Ease of operation
If the umbrella is designed for hand-held use with a bottom handle, then it is easy to use conventionally, but it cannot be easily converted to back-mounted use
Solution Approach 1:
The invention separates the umbrella's handling function (bottom handle for hand-held use) from its mounting function (top attachment point for back-mounted use). This allows the umbrella to maintain its conventional hand-held usability while also being adaptable to back-mounted configuration through the separate anchoring structure.
