Mobile Wood Chipper Sliding Mechanism for Rugged Terrain Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for clearing slash in rugged areas are labor-intensive and costly, as large wood chippers cannot access these areas due to terrain constraints, and even smaller chippers require significant expense and effort to transport.
Innovation Solution
A mobile wood chipper system mounted on a passenger vehicle, with a slidable structure allowing the chipper to transition between stowed and operational positions, powered by a generator mounted on the vehicle, enabling efficient processing of slash in challenging terrains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large wood chippers are used to process slash, then processing efficiency is improved, but accessibility to rugged terrain deteriorates
Solution Approach 1:
The wood chipper system is divided into separable components: a portable chipper unit that can be detached from the vehicle. This allows the vehicle to access rugged terrain independently while the chipper unit can be deployed at the destination for processing operations, resolving the contradiction between vehicle accessibility and processing efficiency.
Solution Approach 2:
A vehicle serves as an intermediary platform that transports the portable chipper unit to locations inaccessible to large chippers. The vehicle provides mobility and access to rugged terrain, while the portable chipper unit attached to it delivers slash processing capability at remote locations.
2Adaptability or versatility
If manual hauling of slash is used, then accessibility to rugged terrain is maintained, but labor intensity increases
Solution Approach 1:
The portable chipper unit enables the system to process slash autonomously at the location where it accumulates, eliminating the need for manual collection and hauling. The unit processes branches and small trees directly at the rugged terrain location, converting labor-intensive manual handling into automated mechanical processing.
3Adaptability or versatility
If portable wood chippers are used, then accessibility to rugged terrain is improved, but processing capacity deteriorates
Solution Approach 1:
The system dynamically adapts its processing capacity to match the scale of operations required in rugged terrain. The portable chipper unit is sized appropriately for the volume of slash typically found in these areas, providing sufficient processing capacity while maintaining the mobility needed for terrain accessibility.
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 easy access to rugged areas with reduced labor and cost, as the wood chipper can be driven on smaller vehicles that can navigate uneven terrain, and the system is designed for convenient operation and safe feeding of materials.
Implementation Method 1
a hydraulic system, which may be powered by a generator, for moving the wood chipper module between the stowed position and the operational position
Implementation Method 2
including rollable members that are supported by and rollable on the horizontal rolling surface of the first portion of the slidable structure

AI summary
A mobile wood chipper that is mounted to a motor vehicle. The wood chipper has an input hopper that during operation is desirably located at a convenient height for a user. In the case of mounting in a station wagon or van, a slidable structure may be used to allow the wood chipper to be slid into an operational position with the wood chipper at least largely outside the vehicle, and a stowed position with the wood chipper at least largely inside the vehicle. In the case of mounting in a truck, a lift mechanism may be used to allow the wood chipper to be lowered into an operational position with the wood chipper at a convenient height for a user, and lifted up into a stowed position within the truck bed. A power generator is also included to supply power to the wood chipper.
