Knotless Fishing Line Coupler With Threaded Groove Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of efficiently and quickly attaching fishing lines to fishing hooks and lures without the use of knots, which can be time-consuming and prone to failure, especially in adverse conditions, due to the complexity of knots and incompatibilities between line and lure materials.
Innovation Solution
The development of knotless line-coupling arrangements that utilize cam mechanisms, frame configurations, and clamping assemblies to securely attach fishing lines to fishing implements, distributing the line's tension evenly and preventing local stress points, allowing for quick and reliable attachment without damaging the line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional knots are used to attach fishing line to hooks and lures, then the attachment can be made securely, but the process becomes time-consuming and complex
Solution Approach 1:
The patent removes the knot-tying step entirely by extracting the attachment function into a separate mechanical component (snap hook, clamp, or snap swivel) that can be attached to the fishing line without requiring knots. This allows anglers to simply clip or snap the implement onto the line, dramatically reducing attachment time while maintaining security.
Solution Approach 2:
The patent introduces intermediary attachment hardware (snap hooks, clamps, snap swivels) that serve as mediators between the fishing line and the implement. These intermediaries provide a standardized, tool-free connection mechanism that eliminates the need for complex knot-tying while ensuring reliable attachment.
2Ease of operation
If conventional knots are used to attach fishing line, then attachment can be achieved, but the process becomes difficult in adverse conditions such as wet or cold environments
Solution Approach 1:
The attachment mechanisms (snap hooks, clamps, snap swivels) are designed to be self-contained and self-operating. The angler simply needs to open the mechanism, place it on the line, and close it - the mechanism itself performs the attachment function without requiring manual dexterity for knot manipulation, making it equally easy to use in dry or wet conditions, cold or warm environments.
3Strength
If knots are tied in fishing lines, then attachment is achieved, but stress points are created that can lead to line breakage
Solution Approach 1:
The patent removes the knot from the fishing line system entirely by using separate attachment hardware. This extraction eliminates the stress concentration points that knots create in the line, allowing the line to maintain its full tensile strength throughout its length without weak points where breakage could occur.
4Adaptability or versatility
If knots are used to attach fishing line, then attachment can be made, but the process becomes complex and requires learning multiple techniques
Solution Approach 1:
The patent employs universal attachment mechanisms (snap hooks, clamps, snap swivels) that can be used with all types of fishing implements (hooks, lures, spoons, spinners) and all types of fishing lines. This single standardized interface replaces the need for anglers to learn and select from dozens of different knot techniques for different applications, greatly simplifying the system while maintaining versatility.

AI summary
A knotless coupler for securing a fishing line to a fishing implement is disclosed. The knotless coupler comprises a shaft portion and a nut. The shaft portion is configured to be attached to the fishing implement. The shaft portion comprises a plurality of external threads and an external line-receiving groove formed across at least some of the external threads. The nut is configured to be threadably engaged with the external threads of the shaft portion. The nut is movable between a non-gripping position and a line-gripping position. A portion of the fishing line is inserted through an opening in the nut and into the external line-receiving groove when the nut is in the non-gripping position. The portion of the fishing line is secured within the external line-receiving groove by the nut when the nut is in the line-gripping position.
