Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing lights for tuna long-line fisheries have limited light emission duration due to small battery capacity and high manufacturing costs associated with reflective materials, which hinder the effectiveness of attracting tuna.
Innovation Solution
A fishing light design featuring a housing with a cap and substrate that includes a light guiding member for refractive diffusion of LED light, enhancing visibility by making the luminous body appear larger through partial transmission and reflection, and using a ball joint or screw connection for assembly simplicity and increased visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If reflective materials are used to enhance light diffusion, then the attraction effect of tuna is improved, but the manufacturing cost increases significantly
Solution Approach 1:
The patent replaces expensive reflective materials with a cost-effective alternative: a transparent adhesive tape wrapped around the battery. This simple, inexpensive material achieves the same light diffusion effect without the high manufacturing costs associated with specialized reflective materials, directly resolving the contradiction between illumination enhancement and manufacturing cost.
Solution Approach 2:
The patent changes the optical parameters of the battery surface by wrapping it with transparent adhesive tape. This simple modification alters how light interacts with the battery surface, enabling effective light diffusion and enhancement of the luminous body appearance without requiring expensive reflective materials, thus resolving the cost-effectiveness contradiction.
2Illumination intensity
If the luminous body is made to appear larger through light reflection, then the attraction effect of tuna is enhanced, but the device complexity increases
Solution Approach 1:
The patent uses a simple transparent adhesive tape instead of complex optical components to achieve light diffusion and enhance the apparent size of the luminous body. This minimalistic approach maintains device simplicity while effectively resolving the contradiction between enhancing luminous body perception and avoiding increased device complexity.
3Volume of moving object
If a button type battery is used, then the device size is reduced, but the light emission duration becomes insufficient for tuna long-line fishing
Solution Approach 1:
The patent nests two AA batteries inside the transparent adhesive tape wrapping within the housing, creating a compact configuration that maximizes battery capacity while maintaining a small device footprint. This nested arrangement resolves the contradiction between device size and light emission duration by efficiently utilizing internal space.
Solution Approach 2:
The patent combines transparent adhesive tape with battery housing materials to create a composite structure that serves multiple functions: protecting the batteries, enabling light diffusion, and maintaining a compact form factor. This composite approach allows the device to accommodate larger battery capacity while maintaining small size, resolving the contradiction between device volume and operation duration.
