Fishing Lure Movable Tail Segmented Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing lures struggle to replicate the realistic swimming movement of baitfish, particularly in the tail portion, due to limitations in mimicking the natural swimming motion when drawn through water.
Innovation Solution
A fishing lure with a movable tail design featuring a flexible caudal stalk, laterally opposing sides, fin rays, upper and lower lobes, central drafts, and lips, which enhance hydrodynamic resistance and create a more lifelike swinging action by projecting outwardly and laterally, mimicking the movement of a baitfish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible tail is added to the lure, then the realism of swimming motion is improved, but the device complexity increases
Solution Approach 1:
The tail is divided into multiple discrete components including upper and lower lobes, central drafts, fin rays, and lips that are separately formed and then attached to the caudal stalk. This segmentation allows each component to be optimized for its specific function while maintaining overall flexibility and realism of motion.
Solution Approach 2:
The tail components are designed with inherent flexibility to move dynamically relative to each other during water flow. The lobes, drafts, and fin rays are configured to oscillate and flex independently, creating a more natural swimming motion that adapts to varying water conditions.
2Reliability
If multiple tail components (lobes, drafts, lips, fin rays) are added, then the hydrodynamic resistance and swimming motion realism are improved, but the manufacturing complexity increases
Solution Approach 1:
Each tail component (lobes, drafts, fin rays, lips) is separately formed using injection molding or similar processes, allowing for precise control of each element's geometry and hydrodynamic properties. The components are then attached to the caudal stalk in a standardized assembly process.
Solution Approach 2:
Different materials or material properties are used for specific tail components to optimize their individual functions. For example, the fin rays may have different flexibility characteristics than the lobes, allowing each component to perform its specific hydrodynamic role effectively.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design results in a more realistic and enhanced swimming motion of the lure through the water, increasing the likelihood of attracting fish by mimicking the natural movement of baitfish, thereby improving fishing effectiveness.
Implementation Method 1
The central drafts are disposed rearwardly of the fin rays on the opposing sides of the tail. The upper lips extend between the central draft and the upper lobe on the opposing sides, and the lower lips extend between the central drafts and the lower lobe on the opposing sides

AI summary
The movable tail on a fishing lure having a flexible caudal stalk basically comprises a pair of laterally opposing sides, a plurality of fin rays, upper and lower lobes, laterally projecting central drafts and upper and lower lips, and a rear surface. The fin rays extend rearwardly from the caudal stalk on each of the opposing sides of the tail. The upper and lower lobes are disposed rearwardly of the fin rays. The central drafts are disposed rearwardly of the fin rays on the opposing sides of the tail. The upper lips extend between the central draft and the upper lobe on the opposing sides, and the lower lips extend between the central drafts and the lower lobe on the opposing sides. The rear surface extends over an area defined by the upper and lower lobes, the central drafts, and the upper and lower lips.
