Cable Reel Trailer Using Towing Force for Passive Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable reel trailers rely on hydraulic or electrical motors, which are prone to breakdowns and require additional power sources, making them complex, costly, and unsafe for transporting heavy loads.
Innovation Solution
A cable reel trailer design that utilizes the automotive force of a towing vehicle to lift and secure the cable reel, eliminating the need for on-board power sources by employing a pivotally connected tongue and cantilever mechanism to distribute weight evenly over the axle, ensuring safe and efficient loading and unloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hydraulic or electrical motors are used to lift the cable reel, then the lifting function is achieved, but the device complexity and power requirements increase
Solution Approach 1:
The patent removes the motor and power supply system from the trailer, extracting the problematic components that caused complexity and reliability issues. The lifting function is achieved instead by utilizing the towing vehicle's automotive force, which pulls the trailer tongue to rotate the cable reel onto the trailer bed without requiring any on-board power source or complex mechanical lifting mechanism.
Solution Approach 2:
The trailer design allows the towing vehicle itself to perform the lifting function through its normal pulling action. The automotive force from the towing vehicle is converted into rotational motion of the cable reel via the trailer tongue and reel geometry, making the system self-sufficient without external motors or power supplies.
2Ease of operation
If hydraulic motors are used for lifting, then the cable reel can be raised and lowered, but the reliability decreases due to breakdown risks
Solution Approach 1:
The patent eliminates hydraulic motors and all associated power supply systems, removing the components that are prone to breakdown. The lifting and lowering function is achieved purely through the mechanical interaction between the towing vehicle's pull and the cable reel's rotation on the trailer, with no moving parts that can fail.
Solution Approach 2:
The patent replaces the complex hydraulic or electrical mechanical systems with a simpler passive mechanical system that uses the towing vehicle's existing force to achieve the same lifting function through geometric relationships between the trailer tongue, cable reel, and trailer bed.
3Adaptability or versatility
If conventional trailers are used, then cable reels can be transported, but additional power sources are required increasing cost
Solution Approach 1:
The patent makes the towing vehicle perform multiple functions: it both transports the trailer and simultaneously performs the lifting operation. The single automotive force source serves dual purposes, eliminating the need for separate power supplies on the trailer while maintaining full transportation capability.
Solution Approach 2:
The trailer design enables the towing vehicle to serve itself by using its own pulling force to load the cable reel, eliminating the need for external or additional power sources. The system leverages the existing functionality of the towing vehicle rather than adding independent lifting capabilities.

Function Achieved in This Case
The solution provides a safer, simpler, and more economical method for transporting cable reels by eliminating the risk of motor failures and load shifting, reducing manufacturing costs, and ensuring stable transportation without additional power requirements.
Implementation Method 1
uses an automotive force from a vehicle, whether it be a tractor, a truck or any other type of transport vehicle as the power source to lift the cable reel onto the cable reel trailer
Implementation Method 2
distributing the weight safely over the axle of the trailer

AI summary
The present invention discloses various aspects of a cable reel trailer that uses the automotive force of a tractor or truck used to transport the trailer, a method of making same, and a method of using. The inclusion of a pivotally connected tongue that is pivotally connected to the main frame of the trailer overcomes many of the aforementioned problems with the prior art because there is no motor or hydraulic system necessary for lifting the cable reel securely on to the trailer. In accordance with the present invention, the towing automotive force, such as a truck, tractor or any other hauling vehicle, provides all the power for lifting the cable reel, rather than requiring a separate power source on the trailer for doing the heavy lifting. By locking up the wheel on the trailer with a wheel stop, the forward movement provided by a towing truck can concentrate on lifting the cable reel instead of moving the trailer forward. This means that no separate on-board power is needed for lifting the cable reel.
