Translucent Lure with Polyhedral Inner Structure for Directional Color Variation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing lures require inconvenient selective coating treatments to achieve color variation with viewing direction, increasing manufacturing complexity and costs.
Innovation Solution
A translucent lure body with a polyhedral inner structure and a core member that divides the hollow portion into two spaces, featuring a multilayer colored region with different colors on the outer surface, allowing color variation based on viewing direction through light reflection and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If selective coating treatment is applied to long projections to achieve color variation with viewing direction, then the biting property for target fishes is improved, but the manufacturing complexity and inconvenience increase
Solution Approach 1:
The body is divided into multiple long projections, with each projection segmented into a light-transmitting portion and a light-reflecting portion. This segmentation allows different color effects to be achieved through simple coating on each segment rather than complex selective coating, resolving the contradiction between color variation capability and manufacturing ease
Solution Approach 2:
Different portions of the long projections are assigned different optical properties: light-transmitting portions allow background colors to show through, while light-reflecting portions display coating colors. This local differentiation enables color variation with viewing direction while simplifying the coating process, as each portion can be coated independently with standard techniques
2Adaptability or versatility
If multiple colored portions are provided on long projections to achieve color variation, then the attractiveness to target fishes is improved, but the manufacturing cost increases
Solution Approach 1:
The translucent body material itself serves as the first colored portion, eliminating the need for additional coating materials for the base color. The light-reflecting portions only require simple coating to achieve the second color, significantly reducing material costs while maintaining color variation capability
Solution Approach 2:
Instead of applying complex multi-layer coatings to achieve color variation, the invention inverts the approach by using the translucent body material as the base color layer and adding simple reflective coatings only where needed. This inversion simplifies the manufacturing process and reduces costs while achieving the same visual effect
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
