Fishing Lure Weight Distribution for Swimming Sinking Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing lures that imitate bait fish struggle to maintain a life-like swimming motion when not actively pulled by a user, losing effectiveness once the user stops pulling.
Innovation Solution
A fishing lure designed to simulate a swimming motion while sinking, featuring a fish-shaped body with specific weight distribution and curvature, allowing it to change direction and vibrate without user input, and incorporating a tow point for enhanced motion simulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lure is designed to vibrate only when pulled by a user, then the vibration is controllable and energy-efficient, but the lure loses life-like behavior when the user stops pulling
Solution Approach 1:
The lure is designed with an automatic vibration mechanism that activates when the user releases the line, allowing the lure to generate its own vibrations without continuous user input. This self-service approach maintains life-like behavior throughout the entire fishing cycle, not just during active pulling.
Solution Approach 2:
The vibration mechanism operates in periodic cycles: vibrating when the user pulls, then vibrating automatically when released, creating alternating phases of user-controlled and autonomous vibration that together maintain continuous life-like behavior.
2Reliability
If the lure sinks vertically, then the sinking is simple and direct, but the lure cannot simulate natural swimming motion
Solution Approach 1:
The lure employs asymmetric weight distribution with the center of gravity positioned below the lateral line and forward of the geometric center. This asymmetric configuration creates automatic angular motion and directional changes during sinking, simulating natural fish swimming patterns rather than simple vertical descent.
Solution Approach 2:
The lure transitions from one-dimensional vertical sinking to two-dimensional angular motion by positioning the center of gravity below the lateral line. This dimensional change enables the lure to pitch and yaw during descent, creating realistic swimming simulations in multiple directions.
3Extent of automation
If the lure changes direction without user input, then the lure exhibits autonomous life-like behavior, but the user has less control over lure movement
Solution Approach 1:
The lure operates in periodic cycles where user control and autonomous operation alternate: the user pulls to retrieve the lure, then releases to allow automatic vibration and direction changing, creating a rhythmic pattern of controlled and autonomous phases that combines both benefits.
Solution Approach 2:
The automatic vibration and direction-changing mechanisms provide visual feedback to fish that enhances the lure's appeal, while the user maintains control through the retrieve phase. The system creates a feedback loop where autonomous behavior attracts fish, and user control allows repeated presentations.
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 lure achieves a more lifelike swimming motion, attracting fish more effectively by simulating natural swimming behaviors, including vibration and directional changes, enhancing fishing success.
Implementation Method 1
the body and weight distribution of the body are configured to provide the lure with the simulated swimming motion while sinking
Implementation Method 2
the dorsal line is convexly curved, the head portion defines a head ventral line which is convexly curved and the rear portion defines a rear ventral line which is concavely curved

AI summary
A lure for fishing configured to simulate a swimming motion while sinking. A further embodiment relates to a lure for fishing which does not sink vertically, but swims downwards at an angle. The lure may change direction without input from the user. In an embodiment the lure vibrates when being pulled by a user (e.g. using a fishing rod), swims downwards at an angle when under no external force, vibrating while it does so and changes direction when sinking. Various characteristics of the lure may contribute to this behaviour such as the weight and shape.
