Underwater Fishing Camera Assembly for Stable Trolling Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underwater fishing cameras lack stability and depth control during trolling, particularly when used separately from a lure, leading to unsteady video recordings and disrupted depth control.
Innovation Solution
An underwater camera assembly with a front tongue and stabilizers that provide downward force and lateral stability, ensuring reduced wobbling and controlled depth, comprising a line attachment system and optional buoyancy for improved handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera is attached directly to the lure (as in US 2017/042136 and US 2018/192624), then the camera can capture fish biting the bait, but the video recordings become unsteady due to the lure's movements and vibrations designed to mimic natural bait
Solution Approach 1:
The system separates the camera into an independent camera assembly that is attached to the fishing line separately from the lure. This segmentation isolates the camera from the lure's wobbling movements, allowing the camera to remain stable while the lure performs its natural bait-mimicking actions.
Solution Approach 2:
The fishing line serves as an intermediary element between the lure and the camera assembly. The camera assembly is attached to the line in front of and separate from the lure, allowing the line to transmit the fishing force while isolating the camera from the harmful vibrations and wobbling generated by the lure's movements.
2Stability of the object's composition
If the camera assembly has no depth control mechanism, then the structure remains simple, but the depth and movement stability during trolling deteriorates
Solution Approach 1:
The camera assembly incorporates vertical dimension elements (front tongue extending downward, stabilizers at angled orientations) to control depth and lateral stability. These dimensional extensions allow the assembly to maintain stable depth and position during trolling without requiring complex active control systems.
Solution Approach 2:
The assembly uses passive physical parameters (buoyancy, drag from stabilizers, downward force from front tongue) to control depth and stability. By adjusting the geometry and orientation of these components, the system achieves stable depth control during trolling without requiring complex active control mechanisms.
3Reliability
If the camera assembly is designed without lateral stabilizers, then the manufacturing remains simple, but the lateral stability and reduction of wobbling during trolling deteriorates
Solution Approach 1:
Lateral stabilizers extend from the camera assembly in directions perpendicular to the main axis of motion. These stabilizers introduce lateral dimensionality to the design, providing resistance to side-to-side wobbling movements during trolling while maintaining relatively simple manufacturing processes.
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 camera assembly achieves stable video recordings and precise depth control, reducing wobbling transfer from lures and enhancing compatibility with various fishing rods, while ensuring easy retrieval in case of line failure.
Implementation Method 1
a front tongue extending downwardly and forwardly from the lower part of the front-end part and configured to exert a downward force on the main body when the assembly is pulled through water in the forward direction
Implementation Method 2
at least two stabilizers extending laterally from the rear-end part at symmetrical angles between 10°-80° from a vertical direction
Implementation Method 3
the camera assembly preferably has positive buoyancy in fresh water

AI summary
An underwater camera assembly to be pulled through water in a forward direction in front of a fishing lure is provided. An elongated main body holding a camera in a waterproof manner has a line attachment system positioned on the lower part of the main body. The camera assembly has a front tongue extending downwardly and forwardly from a lower, front part of the main body and configured to exert a downward force on the main body pulled through water in the forward direction. The assembly comprises stabilizing fins extending laterally from a rear-end part of the main body. The camera assembly has a very low mass while still providing improved stability and depth control during trolling.
