Self-Centering Fishing Lure with Transverse Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing lures require frequent adjustments to maintain correct tracking during trolling, especially at higher speeds, which limits their depth and speed capabilities and can lead to reduced lure lifetime and increased setup time due to manufacturing tolerances and user skill limitations.
Innovation Solution
A self-centring fishing lure design featuring a connection member within a cavity that moves transversely, allowing the lure to balance forces and track correctly without requiring precise initial alignment, enabling operation at speeds up to 15 knots and reducing the need for post-catch adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the attachment point is fixed and precisely aligned during manufacturing, then correct tracking is achieved, but manufacturing precision requirements increase and setup time increases
Solution Approach 1:
The patent applies the dynamics principle by making the attachment point movable rather than fixed. The connection member is allowed to move longitudinally within the cavity along the pull line direction, enabling the system to dynamically adjust and compensate for misalignment automatically during operation, thereby resolving the contradiction between reliability and manufacturing precision.
2Productivity
If trolling speed is increased to improve productivity, then fishing efficiency increases, but water resistance on the line increases causing the lure to swim shallower and not swim straight
Solution Approach 1:
The movable connection member allows the lure to dynamically adjust its position in response to varying water resistance forces at different speeds. This dynamic adjustment compensates for the effects of increased speed, maintaining proper tracking and depth control even at higher trolling speeds, thus resolving the contradiction between productivity and reliability.
Solution Approach 2:
The system employs self-service by allowing the connection member to automatically adjust its position in response to hydrodynamic forces without external intervention. The movable attachment point self-corrects tracking deviations caused by speed variations, enabling the lure to maintain proper operation across a wider speed range and improve fishing efficiency.
3Reliability
If the attachment point is adjusted frequently to maintain correct tracking, then tracking accuracy is maintained, but lure lifetime decreases and setup time increases
Solution Approach 1:
The movable connection member provides self-adjustment capability that eliminates the need for frequent manual interventions. The system automatically compensates for tracking deviations through the movement of the connection member within the cavity, significantly reducing setup time and extending lure lifetime by eliminating repeated adjustments.
4Adaptability or versatility
If larger lures are used to catch larger fish, then catch capability increases, but the lure requires higher trolling speeds which magnifies tracking errors
Solution Approach 1:
The dynamic movable connection member allows larger lures to be trolled at higher speeds while maintaining tracking stability. The ability of the connection member to move and adjust compensates for the magnified tracking errors that occur at higher speeds, enabling anglers to use larger lures for targeting larger fish without sacrificing tracking accuracy.

AI summary
A fishing lure comprises a body having a front end and a rear end. A cavity is positioned towards the front end of the body, and the cavity has a longitudinal direction. A connection member is located at least partially in the cavity and retained thereto by one or more retaining members. Each retaining member is able to extend into the cavity to retain the connection member in the cavity in use. The connection member is able to move, in use, in a direction transverse to the longitudinal direction.
