3D Printed Lure Internal Grid Structure for Water Movement Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lures face limitations in achieving optimal movement in water to attract target organisms, despite adjustments in weight and center of gravity using weights, indicating a need for further improvement in lure design.
Innovation Solution
A lure design featuring an internal array structure with grid lines arranged uniformly, allowing adjustment of weight, center of gravity, buoyancy, and moment of inertia without altering the outer shape, supported by an integrally formed outer shell, and manufactured using 3D printing to enhance strength and integration of eyes and hooks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If weights are used to adjust the weight and center of gravity of the lure, then the weight and center of gravity can be adjusted, but the movement in water is still not favorable enough to attract target organisms
Solution Approach 1:
The internal space is divided into multiple regions by array structures (grid lines) arranged in specific patterns. These segmented regions allow precise control over weight distribution, center of gravity, and buoyancy characteristics without requiring separate weight components, thereby achieving superior movement quality in water
Solution Approach 2:
Different regions within the internal space are assigned different array structure densities or configurations to create localized variations in weight and buoyancy properties. This enables fine-tuned adjustment of the lure's movement characteristics in water to better attract target organisms
2Reliability
If the outer shape of the lure is changed to improve movement in water, then movement may be improved, but the manufacturer cannot provide lures with the same shape that move differently
Solution Approach 1:
The movement control functionality is extracted from the outer shape and relocated to the internal array structures. This separation allows the outer shape to remain consistent while the internal configurations are varied to achieve different movement patterns, enabling manufacturers to offer multiple movement types for the same lure shape
Solution Approach 2:
The design moves from two-dimensional outer shape modification to three-dimensional internal structure configuration. By arranging array structures in specific three-dimensional patterns within the internal space, diverse movement characteristics can be achieved while maintaining a consistent external appearance
3Weight of moving object
If the internal space is left empty to reduce weight, then the lure may be lighter, but the strength of the body is reduced
Solution Approach 1:
The array structures create a porous or grid-like internal configuration that provides structural support while maintaining low weight. The grid lines form a framework that reinforces the body strength without filling the entire internal space with solid material, achieving an optimal balance between weight reduction and structural integrity
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 improved movement in water by adjusting internal parameters, enhancing attraction to target organisms and improving structural strength, while maintaining the same shape, through the use of a 3D printed array structure and integrated eyes and hooks.
Implementation Method 1
the array structure provided in the internal space of the body can be adjusted to change the weight, center of gravity, center of buoyancy, and moment of inertia of the lure
Implementation Method 2
the array structure provided in the internal space of the body can be adjusted to change the weight, center of gravity, center of buoyancy, and moment of inertia of the lure
Implementation Method 3
The lure's array structure can support the outer shell from the inside. Therefore, the strength of the body of the lure having an internal space can be improved
