Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing lures suffer from unstable configurations during flight and after landing in water, with issues of flight distance and swimming stability.
Innovation Solution
A lure design featuring a first body and a second body connected by a swingable connecting portion with a swing range exceeding 90 degrees, utilizing a magnetic regulating member to switch between flight and water configurations, ensuring a stable posture and increased flight distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the second body is made lightweight and soft to distribute weight during flight, then flight distance increases, but the swimming configuration becomes unstable after landing
Solution Approach 1:
The connecting portion is designed to be swingable with a range exceeding 90 degrees, allowing the second body to dynamically adjust its position relative to the first body. During flight, the second body folds forward to optimize aerodynamics and extend flight distance. Upon water impact, the connecting portion swings backward to stabilize the swimming configuration, ensuring the lure maintains proper orientation in water.
2Stability of the object's composition
If the swing range is limited to stabilize swimming configuration, then swimming stability improves, but the ability to achieve folded configuration during flight is reduced
Solution Approach 1:
The swing range parameter of the connecting portion is specifically designed to exceed 90 degrees, enabling the system to achieve two distinct stable configurations: a folded configuration during flight and a swimming configuration in water. This parameter threshold allows the second body to fold forward beyond the vertical axis during flight, then swing back to a stable rearward position in water, providing both flight adaptability and swimming stability.
3Length of moving object
If the center of gravity is positioned toward the front to increase flight distance, then flight performance improves, but the swimming configuration becomes unstable
Solution Approach 1:
The dynamic swing capability of the connecting portion compensates for the forward-biased center of gravity. During flight, the forward center of gravity helps maintain the folded configuration. Upon water impact, the swingable connecting portion allows the second body to rotate backward, repositioning the mass distribution to achieve stable swimming configuration despite the forward center of gravity position.
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 stable configurations during flight and after landing, with enhanced flight distance and reduced hook entanglement, maintaining a folded configuration for increased swimming stability.
Implementation Method 1
The connecting portion includes a magnetic body, and the regulating member includes a magnet that regulates the magnetic body so as to be held at the center of swing of the second swing range by the magnetic force acting on the magnetic body.

AI summary
A lure includes a first body, a second body and a connecting portion. The first body includes a head on a head side and a tail side. The second body includes a tail and is connected to the tail side of the first body. The connecting portion connects the second body to the first body such that the second body is swingable relative to the first body over a swing range that extends to both left and right sides of the lure toward the head side of the first body. The swing range is capable of exceeding 90 degrees on each of the left and right sides, where 0 degrees is defined as when the position of the second body with respect to the first body is such that a line connecting the head and the tail is located on a straight line, as seen in a top view.
