Knotless Hook Line Attachment Device with Rotating Proximal Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing line systems face limitations due to the need for multiple knots, which weaken the line, are time-consuming, and prone to tangling, especially in sport fishing where multiple hooks are required to simulate a school of fish, and existing solutions like the 'clipot' do not fully address twist-related entanglements and knot-related issues.
Innovation Solution
A hook line spreader and attachment device with a proximal portion for free rotation on the leader wire, a distal portion for linking the hook line, and a spacer portion with a stopper featuring a first and second elbow and a retaining portion, allowing the hook line to be secured without knots, thereby preventing tangling and enhancing ease of use and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple knots are made between the main line, leader and hook to secure the hook line, then the hook line is firmly attached, but the line resistance is reduced and the attachment process becomes time-consuming
Solution Approach 1:
The patent introduces a specialized attachment device as an intermediary component between the main line and hook line. This device features a body with a first opening for the main line and a second opening for the hook line, along with a retention member that secures the hook line without requiring traditional knots. The intermediary device maintains attachment security while preserving line strength by eliminating the need for multiple knots.
2Reliability
If multiple knots are made to secure the hook line, then the attachment is reliable, but the attachment process takes too much time
Solution Approach 1:
The attachment device serves as a pre-fabricated intermediary component that eliminates the need for time-consuming knot-tying operations. The device includes a body with openings for both the main line and hook line, and a retention member that can be quickly engaged to secure the hook line. This intermediary solution provides reliable attachment while dramatically reducing the time required compared to traditional multi-knot methods.
3Device complexity
If hook lines are simply tied to the leader wire without spacing devices, then the device complexity is reduced, but the hook lines get tangled easily
Solution Approach 1:
The attachment device acts as an intermediary component that incorporates built-in spacing functionality. The device body includes a spacer portion with a second opening through which the hook line passes, maintaining a fixed distance between the hook line and main line. This integrated approach provides tangling resistance without requiring separate, complex spacing mechanisms, thus balancing simplicity with reliability.
4Ease of operation
If a traditional clip with crenel is used to attach to the leader line, then the attachment is made without knots, but the hook lines still twist and tangle
Solution Approach 1:
The patent introduces an improved attachment device as an intermediary that overcomes the limitations of traditional clips. The device includes a body with a first opening for the main line and a second opening for the hook line, along with a retention member that secures the hook line. Crucially, the spacer portion with the second opening maintains proper spacing and alignment, preventing twisting and tangling while preserving the knotless attachment advantage of traditional clips.

AI summary
The invention relates to a device for quickly spreading and attaching a hook line. The device comprises a proximal portion (1), a spreading portion (2), and a distal portion (3). The proximal portion allows the device to be attached to a leader (10). This attachment is achieved by passing the leader line through a coiled tube (11). The spreading portion (2) includes a stop (5) that retains a loop formed by the hook line (9), a connecting portion (4) that joins the stop (5) to the proximal portion (1), and a winding portion (6) around which the loop strands of the hook line (9) are wound. The hook line (9) is attached by forming a loop with the end opposite the hook. The said loop is placed on the stop (5) and the loop strands are wound around the winding part (6).Finally, we will pass the two strands through the distal portion (3).
