Remote Controlled Pulley for Underwater Accessory Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Underwater fishing accessories with attached cords often become tangled with fishing lines and hooks, hindering fishing and requiring slow, manual retrieval, which can be difficult for a single person, especially when trying to land a caught fish.
Innovation Solution
A remote controlled pulley device with a motorized pulley system, comprising a drive pulley and a follower pulley configured to frictionally engage the cord, controlled by a battery-powered hand-held remote control for efficient lowering and retrieval of underwater accessories like cameras, sonar units, or magnets, with an adjustable cord channel and mounting plate for attachment to above-water structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual retrieval of underwater accessory is used, then the accessory can be retrieved from water, but the retrieval process is slow and difficult for single person
Solution Approach 1:
The patent replaces the manual mechanical retrieval system with an automated motorized pulley system. The motor drives the pulley to automatically wind the cord and retrieve the underwater accessory, eliminating the need for manual pulling and significantly improving retrieval speed while reducing operational difficulty.
Solution Approach 2:
The motorized pulley system performs the retrieval operation autonomously once activated. The system serves itself by automatically winding the cord through motor-driven pulley rotation, without requiring continuous manual intervention, thereby improving both productivity and ease of operation.
2Adaptability or versatility
If accessory is lowered into water with attached cord, then the accessory can be positioned underwater, but the cord may become tangled with fishing line and hook
Solution Approach 1:
The patent separates the accessory positioning function from the fishing operation. By using a dedicated motorized pulley system specifically for lowering and retrieving the accessory, the system extracts the positioning function into an independent automated mechanism, preventing the accessory and its cord from interfering with fishing lines and hooks.
Solution Approach 2:
The motorized pulley system acts as an intermediary between the operator and the underwater accessory. It provides controlled cord deployment and retrieval, managing the accessory's position in water without direct manual handling that could cause tangling with fishing equipment.
3Productivity
If motorized pulley system is used for cord engagement, then the accessory can be quickly positioned and retrieved, but the device structure becomes more complex
Solution Approach 1:
The motorized pulley system is designed to perform multiple functions: lowering the accessory, retrieving the accessory, and controlling cord tension. By consolidating these functions into a single integrated motor-pulley assembly, the system achieves high productivity while managing structural complexity through functional integration.
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
Enables quick and remote positioning or retrieval of underwater accessories, reducing tangling issues and simplifying the process of removing or lowering devices, allowing fishermen to focus on fishing without manual cord handling.
Implementation Method 1
The drive pulley and the follower pulley are configured to frictionally engage the cord

AI summary
A remote controlled pulley device for moving a cord of an underwater accessory comprising a motor; a drive pulley and a follower pulley spaced a distance from the drive pulley for frictionally engaging cord there between. A receiver is in communication the motor, where signals from the receiver cause the motor to turn on and off, which in turn causes the drive pulley to move or rotate in a forward or reverse direction, thus moving the cord frictionally engaged therewith. A battery is provided and configured to power the motor. A battery powered hand-held remote control device is provided and the receiver is configured to receive commands from the hand-held remote control to rotate the drive pulley and thus move the cord.
