Underwater Lighting System Snag-Resistant Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Underwater light systems often get caught in fishing nets or snagged by fishing lines due to their design, which limits the ability of fishermen to cast nets directly over the bait without entanglement.
Innovation Solution
The development of an underwater lighting system with a weighted base and smooth, low-profile design that embeds into the seafloor, featuring a transparent cover and a power supply protector with a weighted core, reducing the likelihood of snagging by burying the lip and power supply into the seafloor, and using materials like stainless steel and elastomers for durability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional underwater light systems are used, then lighting function is provided, but fishing nets and lines get snagged on the system
Solution Approach 1:
The light housing employs a smooth, curved, dome-shaped cover that eliminates sharp edges and protruding components. This spherical curvature allows fishing nets and lines to slide off the surface without catching, directly resolving the snagging problem while maintaining the lighting function through the transparent cover material
Solution Approach 2:
The system is divided into distinct functional segments: a weighted base for anchoring, a smooth curved housing for snag-free operation, and a transparent cover for light transmission. This segmentation allows each component to optimize its specific function while collectively solving the overall problem
2Stability of the object's composition
If the underwater light system is placed on the seafloor, then stability is improved, but fishing nets still get caught on exposed components
Solution Approach 1:
The weighted base features a smooth, curved bottom surface that contacts the seafloor, providing stable anchoring while eliminating sharp edges that could catch fishing gear. The entire system profile is streamlined to prevent entanglement during net casting operations
3Stability of the object's composition
If a weighted base is added to stabilize the system, then stability improves, but the system becomes more complex
Solution Approach 1:
The weighted base is integrated directly with the light housing as a unified structure, eliminating the need for separate mounting hardware or complex assembly mechanisms. This merging provides stable anchoring through the weighted base while keeping the overall system design simple and straightforward

Function Achieved in This Case
This design allows fishermen to cast nets directly over the bait without entanglement, maximizing catch efficiency and safety for both fishing and boat operations, while preventing biofilm buildup and barnacle attachment through ultrasonic excitation and coatings.
Implementation Method 1
an ultrasonic transducer coupled to the cover such that the ultrasonic transducer prevents accumulation of a biofilm on the cover
Implementation Method 2
The light housing may include a weighted base... burying the lip and power supply into the seafloor
