Field Maintenance Vehicle for Nutrient-Poor Grassland Restoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for maintaining or restoring nutrient-poor grassland areas are inefficient, often requiring manual labor and can damage the terrain, and existing vehicles lack the necessary cutting and conveying capabilities to effectively manage woody vegetation.
Innovation Solution
A surface maintenance vehicle equipped with a cutting device for separating woody vegetation and a conveyor system to collect and remove the vegetation, allowing for efficient maintenance with minimal manual effort and reduced terrain impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual methods are used to remove vegetation, then labor intensity is high and precision is low, but the terrain is not damaged
Solution Approach 1:
The patent introduces a conveyor system as an intermediary between the cutting device and the collection point. The conveyor belt transports the cut vegetation away from the cutting zone, preventing it from accumulating and causing terrain damage while maintaining continuous operation. This mediator allows the heavy vehicle to operate without directly impacting the terrain through vegetation accumulation.
Solution Approach 2:
The patent extracts the vegetation removal function from the cutting device by introducing a separate conveyor system. The cutting device focuses solely on cutting, while the conveyor system handles the removal and transport of vegetation. This separation allows the vehicle to maintain high productivity without the cutting device needing to handle vegetation disposal, reducing terrain impact.
2Productivity
If heavy vehicles are used for area maintenance, then productivity increases, but the vehicle weight damages the grassland surface
Solution Approach 1:
The conveyor system acts as an intermediary that allows the heavy vehicle to operate at high speeds without directly impacting the surface. By continuously removing vegetation through the conveyor belt, the vehicle avoids the need to slow down for vegetation accumulation, maintaining high productivity while the conveyor mechanism protects the surface from direct vehicle contact effects.
3Productivity
If cutting devices are added to increase vegetation removal capability, then productivity improves, but the device complexity and weight increase
Solution Approach 1:
The patent segments the vegetation management system into distinct functional modules: a cutting device for separation, a conveyor system for transport, and a collection mechanism. This segmentation allows each component to be optimized independently and simplifies the overall structure by assigning specific functions to each module, reducing unnecessary complexity while maintaining high productivity.
4Reliability
If frequent maintenance is performed to prevent overgrowth, then grassland quality is maintained, but time and resource consumption increase
Solution Approach 1:
The patent implements continuous vegetation removal through the conveyor system that operates throughout the vehicle's movement. This continuous action prevents vegetation from accumulating to problematic levels, maintaining grassland quality over longer periods. The continuous removal process eliminates the need for frequent stop-and-go maintenance operations, reducing time loss while ensuring reliable grassland condition management.
