Curved Magnetic Boat Hook Pole for Dry Trailer Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current process of attaching a boat to a trailer requires individuals to enter the water, which is time-consuming and often necessitates multiple people, making it inconvenient.
Innovation Solution
A retractable pole with a curved magnet is used to attach to a boat U-bolt, allowing the boat to be hooked onto a trailer from land, utilizing an extendable and retractable mechanism with a crank system to pull the boat onto the trailer without water entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a person enters the water to hook the boat to the trailer, then the boat can be attached to the trailer, but the process becomes time-consuming and requires multiple people
Solution Approach 1:
The patent introduces a magnetic attachment device as an intermediary tool between the person and the boat. The device includes a magnetic grip that attaches to the boat's U-bolt and a retractable pole with a hook that connects to the trailer, allowing the person to operate from land without entering the water, thus reducing time and simplifying the attachment process
Solution Approach 2:
The patent replaces the traditional mechanical system of manual hooking (requiring water entry and direct hand manipulation) with a magnetic attachment system. The magnetic grip provides automatic attachment to the U-bolt, and the retractable pole with crank mechanism automates the extension and retraction process, eliminating the need for water entry and reducing manual effort
2Ease of operation
If a person enters the water to hook the boat, then the attachment can be made, but multiple people are often needed
Solution Approach 1:
The magnetic attachment device serves as an intermediary that bridges the gap between the person on land and the boat in the water. The extended pole with magnetic grip allows a single person to reach and attach the boat from the trailer, eliminating the need for multiple people or water entry
Solution Approach 2:
The patent replaces the complex human coordination system (multiple people needed for manual hooking) with a simplified mechanical system consisting of the retractable pole, magnetic grip, and crank mechanism. This automated mechanical system performs the attachment task that previously required multiple human operators
3Length of moving object
If the pole is extended to reach the boat U-bolt, then attachment is possible, but the mechanism becomes more complex
Solution Approach 1:
The retractable pole is designed with a telescoping structure where segments of the pole nest within each other when retracted, similar to a nested doll configuration. This allows the pole to extend to the necessary length for reaching the boat U-bolt while maintaining a compact form when not in use, managing the complexity through elegant structural design
Solution Approach 2:
The patent employs a dynamic retractable pole mechanism that can extend and retract as needed. The pole transitions from a compact retracted state to an extended operational state, allowing the device to adapt its length to the situation. This dynamic capability is achieved through the telescoping structure and crank mechanism, which manage the complexity through controlled motion

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 single-person operation to efficiently attach and retract a boat from the water to the trailer, reducing time and labor requirements.
Implementation Method 1
a curved magnet at a proximal end of the elongated rigid pole, the curved magnet attracted to and fitting over a metal hook of a trailer

AI summary
A device for pulling a boat onto a trailer from the water includes a curved magnet with rubber side grips attached to a proximal end of an elongated, retractable, rigid pole. The magnet grabs a metal hook on the end of a boat trailer. The pole allows attachment of the trailer hook to the boat U-bolt without the need for an individual to get into the water to attach the boat. The pole can be stored when not in use, using straps.
