Fishing Lure Cavity for Multi-Directional Specular Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing lures fail to effectively attract fish due to weak or diffused reflected light, which reduces their fish-attracting effectiveness.
Innovation Solution
The lure incorporates multiple specular reflecting surfaces and reflectors on its outer and inner faces, allowing light to be reflected multiple times to enhance luminance and directionality, mimicking the reflective behavior of bait fish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a small reflector is sealed with liquid in a body to generate reflected light, then light reflection is achieved, but the reflected light is weak and does not reach fish eaters depending on the angle of light
Solution Approach 1:
The lure body is divided into multiple light-reflecting members with different reflection characteristics (specular reflection members and diffuse reflection members), allowing the system to reflect light in multiple directions simultaneously while maintaining high intensity in specific directions
Solution Approach 2:
Different portions of the lure have different reflective properties - some areas have specular reflection surfaces for strong directional reflection, while other areas have diffuse reflection surfaces for broader light distribution, optimizing both intensity and angular coverage
2Illumination intensity
If an irregular reflection layer with recesses and protrusions is used to create color development, then color variation is achieved, but the reflected light is diffused and fails to form strong reflected light
Solution Approach 1:
Instead of creating complex irregular reflection layers with recesses and protrusions, the invention uses simpler specular reflection surfaces (such as mirrored surfaces or smooth reflective coatings) that replicate the light-reflecting function of fish scales more effectively
Solution Approach 2:
The invention changes the reflection parameter from diffuse/irregular reflection to specular reflection, fundamentally altering how light interacts with the lure surface to achieve stronger reflected light while simplifying the manufacturing process
3Illumination intensity
If multiple light-reflecting members are provided inside the lure body to reduce attenuation, then reflected light luminance is enhanced, but the device complexity increases
Solution Approach 1:
Multiple light-reflecting members with different reflection characteristics are combined within the lure body to achieve both high luminance and broad angular coverage, resolving the contradiction between complexity and performance
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 significantly increases the intensity and directionality of reflected light, making it more attractive to fish and enhancing its fish-attracting capabilities.
