Rotatable Wing Sidetracker for Fishing Lure Lateral Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing lures lack effective mechanisms to control lateral movement and turbulence in deep-sea fishing, leading to reduced effectiveness in attracting large fish species like marlin, tuna, and sharks.
Innovation Solution
A fishing sidetracker with a torpedo-shaped body, fins, and a detachable wing system that utilizes an X-shaped channel to control vertical and lateral positions, allowing the lure to be directed laterally and maintaining contact with water, thereby reducing turbulence from boat motors and increasing lure spread.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fishing lures are used without lateral control mechanisms, then the lure follows a simple trail behind the boat, but the lure cannot effectively control lateral movement or reduce turbulence from boat motors
Solution Approach 1:
The wing is made rotatable about a transverse axis, allowing it to dynamically adjust its orientation between longitudinal and lateral positions. This dynamic capability enables the lure to adapt to different fishing conditions and control lateral movement, while the rotatable mechanism maintains reasonable structural simplicity through a single degree of freedom.
Solution Approach 2:
The lure is divided into distinct functional components: a body, a rotatable wing, and a mounting mechanism. The wing can be positioned in different orientations (longitudinal or lateral) relative to the body, allowing independent control of vertical and lateral positions. This segmentation enables complex functionality while maintaining modular simplicity.
2Adaptability or versatility
If the wing is fixed in one position, then the structure is simple, but the lure cannot adapt to different fishing conditions or effectively control both vertical and lateral positions
Solution Approach 1:
The wing's rotatability provides adaptability by allowing it to be positioned in different orientations based on fishing conditions. The single rotatable joint provides the necessary versatility to control both vertical and lateral positions without requiring multiple independent actuators or complex mechanisms.
Solution Approach 2:
The rotatable wing serves multiple functions: it can control vertical position when in the longitudinal orientation, control lateral position when in the lateral orientation, and the ability to rotate between these positions provides adaptive versatility. This multi-functionality is achieved through a single rotational degree of freedom, maintaining mechanism simplicity.
3Area of stationary object
If multiple lures are trailed behind the boat, then the coverage area increases, but the lures create turbulence that reduces their effectiveness
Solution Approach 1:
The rotatable wing allows the lure to dynamically adjust its orientation to optimize its position in the water, helping it maintain contact with the water surface and reduce turbulence. This dynamic positioning capability enables multiple lures to be trailed more effectively by minimizing their mutual interference.

AI summary
A directional guide for a spreader bar includes a body extending along a longitudinal axis. The body includes a first fin and a second fin spaced apart from the first fin. The first and second fins are coupled to the body and are configured to control a vertical position of the body in water through which the body is moving. Grooves are formed in the body. The grooves include a first groove extending along the longitudinal axis of the body, a second groove crossing the first groove and a third groove crossing the first groove. A keel is rotatably coupled to the body. The keel is configured to rotate between the first groove, the second groove, and the third groove. The keel is configured to control a lateral position of the body in water through which the body is moving.
