Knotting Assembly With Slip-Resistant Tubes And LED
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Anglers face challenges in securely and safely tying fishing line knots and splices, especially in cold weather or with arthritis, as existing devices lack slip-resistant surfaces and are not designed for various knot types, leading to weak connections and potential hand injuries.
Innovation Solution
A hand-held assembly comprising cylinders and slip-resistant tubes with integrated LEDs and magnets, allowing for hands-free illumination and secure storage, which restrains the line in a loose knot pattern and tightens the knot by stretching, providing a non-slip surface and enabling stronger knot formation without direct hand force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a fishing line knot is tied by hand, then the knot can be formed, but the connection strength is weak and hand injury risk increases
Solution Approach 1:
The patent introduces a knot-tying device with cylindrical components that act as an intermediary between the user's hands and the fishing line. The device includes a first cylindrical component with a first end and a second cylindrical component with a second end, where the line is positioned between these components. The user applies force to the cylindrical components rather than directly to the line, which prevents hand injury while maintaining knot strength.
Solution Approach 2:
The knot-tying device is segmented into multiple functional components: first and second cylindrical components, first and second ends, and positioning elements. This segmentation allows each component to perform a specific function - the cylindrical components provide structural support and force application points, while the positioning elements secure the line in place during knot formation.
2Manufacturing precision
If the line is restrained in a loose knot pattern while stretching, then the knot tightens properly, but the device complexity increases
Solution Approach 1:
The device applies local quality by providing specific positioning elements at critical locations on the cylindrical components. These positioning elements are strategically placed to restrain the line in a loose knot pattern during formation, ensuring proper knot geometry without requiring complex mechanisms throughout the entire device structure.
Solution Approach 2:
The device performs preliminary action by pre-positioning the line between the first and second cylindrical components in the correct loose knot pattern before the user applies tightening force. This preliminary positioning ensures that the knot forms correctly and tightens uniformly, improving manufacturing precision while keeping the device relatively simple.

AI summary
A method and assembly for knotting a line restrains a fishing line in a loose knot pattern while a knot or splice is formed in the fishing line to enable tightening the knot by stretching the line. The assembly includes a pair of cylinders having an external surface, a first end, and a second end. A pair of tubes encapsulate the pair of cylinders to provide a slip resistant surface. Two pair of caps comprising an open end and a closed end detachably attach to the first and second ends of the tubes. The caps include at least one flat surface region having a depression. One cap per tube includes a light emitting diode (LED) which enables hands free illumination while knotting or splicing line. Magnets are integrated into the cap depressions to enable magnetic attraction between tubes. Fishing line wrap around the tubes to enable knotting and splicing.
