Cross-Body Umbrella Harness for Hands-Free Ergonomic Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compact umbrellas are inconvenient for hands-free use, causing muscle fatigue and moisture transfer when carried in bags, and full-sized umbrellas lack ergonomic hands-free solutions.
Innovation Solution
A harness system with a cross-body strap, top and base clips, and adjustable truss assemblies for securing and stabilizing umbrellas, allowing for hands-free operation and ergonomic use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If compact umbrellas are carried in bags for portability, then portability is improved, but muscle fatigue and moisture transfer occur
Solution Approach 1:
A harness system with cross-body strap and clips serves as an intermediary carrier between the user and the umbrella. The top clip secures the umbrella shaft to the cross-body strap near the shoulder, while the base clip secures the umbrella base to the same strap, distributing the umbrella's weight and preventing it from being carried in bags that cause moisture transfer.
2Area of stationary object
If full-sized umbrellas are used for better coverage, then protection area is improved, but portability deteriorates
Solution Approach 1:
The harness system is designed to accommodate both compact and full-sized umbrellas through universal top and base clips that can secure various umbrella types. The cross-body strap configuration allows large umbrellas to be worn hands-free, providing the coverage area benefit without the portability drawback of carrying large umbrellas in bags.
3Ease of operation
If umbrellas are held by hand for hands-free use, then ease of operation is improved, but muscle fatigue increases
Solution Approach 1:
The umbrella support function is segmented into two separate attachment points: a top clip securing the upper shaft portion and a base clip securing the lower base portion. This segmentation distributes the umbrella's weight across different body locations via the cross-body strap, enabling prolonged hands-free use without the muscle fatigue associated with holding umbrellas by hand.
4Stability of the object's composition
If cross-body strap is positioned higher for better umbrella support, then umbrella stability is improved, but comfort deteriorates
Solution Approach 1:
The cross-body strap is designed with adjustable positioning features, allowing users to dynamically adjust the strap height and tension based on their comfort preferences and umbrella size. The top and base clips can also be repositioned along the strap to optimize both umbrella stability and user comfort for different carrying scenarios.

AI summary
A harness for hands-free use of personal umbrellas uses a cross-body strap circling a user from one shoulder to the opposite waist and a top clip to hold the umbrella at the shoulder. The harness can have one or more side straps passing around the torso under the shoulder, a base clip holding the umbrella at a waist level, and/or a bag for holding the umbrella, the straps, the clips, and/or personal items of the user. The top clip and/or base clip can be on mounts and/or booms. The clips can be adjustable in angle relative to the torso. Booms can be adjustable in length. A mount can include an adjustable truss assembly for positioning the umbrella. The bag can have compartments made with varied materials for different moisture performance. The harness can be adapted for use with full-size umbrellas and/or compact umbrellas with collapsible shafts.
