Rollable Track Deployment Apparatus for Sensitive Terrain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles traveling on sensitive or vulnerable terrain, such as grassy areas, often leave deep tread marks and damage the turf, requiring costly repairs and maintenance, or necessitate the use of manpower to avoid damage, which is time-consuming and inefficient.
Innovation Solution
A track system comprising rollable tracks with connected slat members and strap elements that disperse the vehicle's weight, allowing it to travel without causing significant damage, including a deployment apparatus for unrolling and securing the tracks in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicles travel directly on sensitive terrain, then transportation efficiency is improved, but terrain damage occurs
Solution Approach 1:
The patent introduces a track system as an intermediary between the vehicle and the terrain. The track distributes the vehicle's weight across multiple contact points along its length, reducing ground pressure and preventing terrain damage while enabling vehicle movement. The track acts as a mediator that transfers the vehicle's load to the ground in a distributed manner rather than concentrated wheel loads.
Solution Approach 2:
The track system is divided into multiple discrete slat members connected together. This segmentation allows the track to flex and conform to terrain variations while distributing the vehicle weight across numerous individual slats rather than a continuous solid surface, further reducing ground pressure and minimizing terrain damage.
2Object-affected harmful factors
If track systems are deployed to protect terrain, then terrain damage is prevented, but deployment complexity increases
Solution Approach 1:
The track system is designed to be dynamically deployable and retractable. The track can be unrolled from a compact state to a deployed state when needed, and retracted when not in use. This dynamic capability allows the system to transition between storage and operational states, reducing the perceived complexity by only requiring full deployment when terrain protection is needed.
Solution Approach 2:
The track system is pre-assembled into connected slat members that can be rapidly deployed. The slats are pre-connected with interlocking mechanisms that allow quick assembly without requiring complex field construction, reducing deployment complexity while maintaining terrain protection capabilities.
3Object-affected harmful factors
If manual transport is used to avoid terrain damage, then terrain damage is minimized, but time and effort increase
Solution Approach 1:
The track system is designed to be self-deploying through the vehicle's own movement. As the vehicle moves forward, the track automatically unrolls and positions itself beneath the vehicle, eliminating the need for manual deployment. The vehicle's propulsion system provides the force needed to unroll the track, making the deployment process automatic and reducing both time and manual effort.
4Object-affected harmful factors
If rollable tracks are used to disperse weight, then terrain damage is reduced, but connection reliability must be maintained
Solution Approach 1:
The connection interfaces between slat members feature curved or rounded surfaces that guide proper alignment during assembly. The curved connection surfaces ensure that slats connect in the correct orientation, maintaining structural integrity and reliability while allowing for slight misalignments during deployment. The curvature facilitates smooth engagement of the interlocking mechanisms.

AI summary
A track system may include a plurality of connected slat members that may form rollable tracks. The rollable tracks may be used in moving vehicles across sensitive ground. The rollable track may be deployed using various methods and/or apparatus such as, e.g., deployment apparatus including one or more spool portions for rolling and unrolling the rollable tracks.
