Lure Weight Guide Structure for Flexible Center-of-Gravity Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lures have limited weight movement paths, restricting optimal center of gravity positioning and stability, and are limited to specific weight shapes, affecting the lure's attitude and internal structure.
Innovation Solution
A lure design featuring a support part that can elastically deform in an intersecting direction, guided by a guide portion within the main body, allowing the weight to move in both front-rear and intersecting directions, with restricting and slit portions to stabilize the center of gravity and movement path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shaft is formed in a straight line, then the movement path of the weight is limited to being straight, but it is difficult to dispose the weight at positions thought to be optimal depending on the shape and internal structure of the lure
Solution Approach 1:
The guide portion is designed to enable the weight to move not only in the front-rear direction (longitudinal axis) but also in the intersecting direction (vertical axis), transitioning from one-dimensional linear movement to two-dimensional curved movement. This allows the weight to reach optimal positions that are not accessible with a straight shaft, while the guide portion's integrated design avoids excessive structural complexity.
2Adaptability or versatility
If a plurality of weights are guided by a movement passage formed inside the lure, then the shape of the weight is limited to a sphere or a similar shape, but the attitude of the weight in the movement passage is not stable
Solution Approach 1:
The guide portion is designed with specific geometric features including a curved surface and a leading edge that protrudes in the front-rear direction. This localized geometric design provides directional guidance and stabilizing forces that maintain the weight's attitude (orientation and position) while allowing the weight to have various shapes beyond spheres, thus achieving both shape adaptability and attitude stability.
3Manufacturing precision
If the weight moves linearly along the shaft, then the movement path is simple, but the center of gravity position cannot be optimally adjusted for different lure configurations
Solution Approach 1:
The guide portion is designed to enable dynamic movement of the weight along a curved path rather than a fixed linear trajectory. The curved guide surface allows the weight to move in both front-rear and intersecting directions, providing dynamic adjustment capability for the center of gravity position. This dynamic positioning capability is achieved through the integrated curved guide structure, balancing positioning precision with structural complexity.
