Underwater Camera Line Attachment and Power Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underwater fishing cameras are bulky, require cutting of fishing lines for attachment, and have limited power supply, making them difficult to position accurately and operate continuously.
Innovation Solution
An underwater camera system with a waterproof housing and line attachment system that allows secure attachment to a continuous fishing line without cutting, featuring a generator for self-powering through movement, and advanced features like 3-axis sensing and GPS for accurate data capture and annotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an independent underwater camera is used with a trailing cable, then power supply and data transmission are ensured, but the camera becomes bulky and difficult to position accurately near the fishing line
Solution Approach 1:
The system divides the camera unit into a separate, compact waterproof housing that attaches directly to the fishing line, separating it from the bulky cable assembly. This segmentation allows the camera to be positioned accurately on the line while the cable remains separate for power and data transmission.
Solution Approach 2:
The camera is nested within a compact waterproof housing that integrates directly with the fishing line attachment system. This nested structure eliminates the need for external cable management near the camera, improving positioning accuracy while maintaining reliable connections.
2Measurement precision
If an in-line underwater camera is attached to the fishing line, then accurate shots can be recorded, but the fishing line must be cut for attachment
Solution Approach 1:
The attachment system uses dynamic clamps that can be opened and closed to secure or release the fishing line without cutting it. This dynamic mechanism allows the camera to be attached and removed from continuous filament lines, maintaining shot accuracy while enabling easy reconfiguration.
Solution Approach 2:
The clamp mechanism changes its gripping parameter from open to closed state, allowing the line to be secured without cutting. This parameter change enables reversible attachment while maintaining the structural integrity and behavior of the fishing line.
3Measurement precision
If an underwater camera is attached to the fishing line, then accurate recording is achieved, but the additional weight changes the behavior of the bait or lure
Solution Approach 1:
The attachment system incorporates buoyant elements that counterbalance the weight of the camera housing. This anti-weight approach minimizes the net effect on the fishing line, preventing changes in bait or lure behavior while maintaining accurate recording capability.
4Ease of operation
If a camera is limited by battery life, then portability is maintained, but continuous recording is not possible
Solution Approach 1:
The system enables continuous recording by providing uninterrupted power supply through the integrated cable connection. The camera can record indefinitely as long as the cable remains connected, eliminating battery life limitations while maintaining portability through the compact housing design.

AI summary
Disclosed is an underwater camera including a waterproof housing comprising a main body configured to contain a camera and a lens aperture for a lens of the camera. A line attachment system is configured to secure the waterproof housing to a continuous filament, such as a fishing line, such that the underwater camera is capable of sliding along the continuous filament.
