Water Tractor Floating Tracks Shallow Water Maneuver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tractors and tugs face challenges in navigating water surfaces due to their weight, leading to high fuel consumption, limited maneuverability, and risk of propeller damage in shallow waters, as well as difficulties in shallow water operations and lack of traction.
Innovation Solution
A water tractor with floating tracks made of polyurethane foam covered in fiberglass, equipped with an Anti-turbulence Fairing System and ovoid rails, allowing for 360° rotation and enhanced traction, reducing hydrodynamic drag and turbulence, and featuring a locking mechanism that acts like oars for increased maneuverability and buoyancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional tugs with large propellers are used to move through water, then towing capability is achieved, but fuel consumption increases significantly
Solution Approach 1:
The continuous track is segmented into multiple floating caterpillars connected in series, allowing the propulsion system to distribute force across multiple discrete buoyant elements rather than relying on a single large propeller, reducing energy loss to turbulence and cavitation
Solution Approach 2:
The patent replaces the conventional propeller-based mechanical propulsion system with a floating track system that utilizes hydrodynamic drag reduction and buoyancy-based movement, eliminating the need for high-power engines and large propellers
2Force
If conventional track tractors are used on land, then traction on solid surfaces is achieved, but operation on water surface is impossible due to weight and lack of floats
Solution Approach 1:
The track segments are designed as floating caterpillars made of polyurethane foam that provide buoyant force to counteract the weight of the tractor, enabling operation on water surfaces where conventional heavy track tractors would sink
Solution Approach 2:
The floating tracks use composite construction with polyurethane foam core for buoyancy, fiberglass reinforcement for structural strength, and rubber coating for durability and water resistance, combining properties needed for both aquatic and terrestrial operation
3Speed
If propellers are used in shallow waters, then propulsion is achieved, but propeller crash at the bottom causes breakage
Solution Approach 1:
The patent extracts the vulnerable propeller component from the system and replaces it with a floating track propulsion mechanism that operates by displacing water with the track segments themselves, eliminating the risk of propeller strike on the river bottom
Solution Approach 2:
The floating track segments act as an intermediary between the tractor and water, providing a distributed propulsion interface that prevents direct contact between any single point (like a propeller) and the river bottom
4Ease of operation
If conventional watercraft are used in shallow waters, then navigation is possible, but maneuverability is limited and grounding on sandbars occurs
Solution Approach 1:
The floating track system allows dynamic adjustment of the tractor's position and orientation by independently controlling the movement of individual track segments, enabling 360-degree rotation and precise maneuvering in confined shallow water spaces
Solution Approach 2:
The patent adds a vertical dimension to propulsion by using floating track segments that can be elevated above the river bottom, allowing the tractor to navigate over obstacles and operate in extremely shallow waters without grounding
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 solution significantly reduces fuel consumption, enhances traction, and enables operation in shallow waters without risk of grounding, allowing for efficient towing of large barges with improved safety and durability.
Implementation Method 1
Massive caterpillars of polyurethane foam, covered with fiberglass, besides to present great impact resistance and therefore durability and security for all equipment, they allow greater buoyancy, eliminating or reducing the risk of sinking by flooding
Implementation Method 2
The Anti-turbulence Fairing System, between the Caterpillars, provides an extremely smooth roll of tracks by removing the crash with water
Implementation Method 3
locks that work as oars in each of these tracks, giving to them great traction capacity in the water

AI summary
The present patent consists of a vehicle equipped with a series of floating caterpillars that circulate on an ovoid rail, forming a continuous track; the male-female couplings between the traction caterpillars, their hydrodynamic locks and their direction system operate with the braking of one of the sides of the track and the slipping of the opposite track, being able to rotate through 360°. Said vehicle has the purpose of towing load barges on rivers or lakes. Due the absence of displacement, since the vehicle moves on the water, the performance is distinctly improved and the fuel consumption is considerably reduced in comparison with watercraft having an equivalent load-carrying capacity.
