Remote Control Vegetation Cutting System with Spiral Flail Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing yard maintenance tools for trimming and mowing vegetation on adverse terrain require operators to be in direct contact with the equipment, exposing them to physical strain, harsh conditions, and safety risks due to uneven terrain and unpredictable environmental hazards.
Innovation Solution
A remote control vegetation cutting system with a trimmer device equipped with a floating flail head chassis, stabilizing battery ball chassis, and multi-channel radio controller, allowing for safe operation from a distance, with features like independent wheel control, adjustable cutting height, and emergency shutdown, to navigate and maintain uneven terrain safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator uses existing yard maintenance tools for trimming and mowing vegetation on adverse terrain, then the cutting function is achieved, but the operator is exposed to physical strain, harsh conditions, and safety risks due to uneven terrain and unpredictable environmental hazards
Solution Approach 1:
The patent introduces a remote control system as an intermediary between the operator and the cutting device. The operator controls the mower from a safe distance using a remote control unit, eliminating direct exposure to adverse terrain conditions, flying debris, and environmental hazards while maintaining full operational control of the cutting function
2Adaptability or versatility
If the operator carries boom type trimmers to access adverse terrain areas, then the ability to reach difficult areas is improved, but additional stress is placed on the neck, back, shoulders, hands, wrists, legs, and ankles of the operator
Solution Approach 1:
The patent replaces the manual mechanical carrying system with a self-propelled robotic mower equipped with wheeled mobility. The device autonomously navigates to adverse terrain areas using its drive system, eliminating the need for the operator to physically carry the equipment and thereby removing the associated physical stress on the operator's body
3Object-affected harmful factors
If the operator uses protective clothing to shield from flying debris, then protection from expected hazards is improved, but standard protective gear cannot always protect the operator from unexpected environmental dangers
Solution Approach 1:
The remote control system serves as a reliable intermediary that physically separates the operator from all hazardous environments. This eliminates the need for protective clothing entirely, as the operator never enters the hazard zone, providing absolute reliability of protection against both expected and unexpected environmental dangers
4Productivity
If a trimmer encounters ground level bee's nest or accidentally causes the release of a concentrated pollen cloud, then the cutting function continues, but the operator is immediately subjected to a potentially life threatening environment
Solution Approach 1:
The remote control system maintains the operator outside the hazard zone even when the cutting device encounters dangerous conditions such as bee nests or pollen clouds. The operator can continue monitoring and controlling the cutting operation from a safe distance, ensuring both productivity continuity and complete protection from life-threatening environmental factors
