Umbrella Rig Storage Sheath Preventing Hook Entanglement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Umbrella rig fishing assemblies are difficult to contain due to their outwardly biased arms, which cause entanglement with other objects and make storage and retrieval challenging.
Innovation Solution
A hollow tubular sheath with a tapered and flared design, featuring a continuous slit, is used to contain and store the umbrella rig by collapsing the arms as the rig is inserted, allowing for easy storage and quick release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the umbrella rig arms are left outwardly biased for easy deployment, then the rig can be quickly set up, but the hooks become entangled with surrounding objects during storage and handling
Solution Approach 1:
The patent places the outwardly biased umbrella rig arms inside a hollow tubular sheath during storage, with the arms nested within the tube's interior space. The sheath contains the arms in a compact configuration, preventing them from snagging on surrounding objects while allowing quick deployment by removing the sheath.
Solution Approach 2:
The patent uses a flexible hollow tubular sheath that can be easily removed and reapplied. The sheath's flexible nature allows it to accommodate the outwardly biased arms during insertion and storage, while its tubular structure provides containment to prevent entanglement with surrounding objects.
2Object-generated harmful factors
If the umbrella rig arms are contained within a sheath to prevent tangling, then entanglement is reduced, but the device complexity increases
Solution Approach 1:
The patent employs a simple flexible hollow tubular sheath as the containment structure. This single-component design provides effective entanglement prevention without introducing complex mechanisms, maintaining ease of use while solving the entanglement problem.
Solution Approach 2:
The sheath provides a simple nested containment structure where the umbrella rig arms are stored within the hollow tube. This nested arrangement prevents entanglement with minimal added complexity, as the sheath is a straightforward tubular component that can be easily attached and removed.
3Ease of operation
If the sheath has a flared end to facilitate insertion, then the arms can be easily collapsed and inserted, but the manufacturing precision requirements increase
Solution Approach 1:
The patent incorporates a flared end geometry on the hollow tubular sheath that gradually increases in diameter. This parameter change in the sheath's cross-sectional dimension facilitates easy insertion of the outwardly biased arms by providing increasing clearance, while remaining manufacturable with standard tolerances.

AI summary
A fishing accessory in the form of a straight and rigid hollow tubular sheath for containing and storing a fully assembled umbrella fishing rig. The majority of the length of the sheath is straight and is provided with a first open tapered end and a second open flared end. A curved slit extends between the two ends and communicates with a hollow interior of the sheath. A user draws the fishing rig into the sheath by pulling the fishing line which is attached to the head of the umbrella rig through the slit from the flared end to the tapered end. Outwardly biased arms of the rig collapse as they are drawn into the sheath, and the hooks of the rig are stored extended over a flared lip at the flared end of the sheath. The outwardly biased arms hold the rig within the sheath.
