Mowing Unit Insect Protection With Adjustable Support Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insect protection systems for mowing devices are cumbersome and inefficient, requiring manual adjustment to navigate around obstacles like trees and signs, and are not cost-effective.
Innovation Solution
A protective device with a scaring unit and adjustable support arms that allow variable distance and angle adjustment relative to the mower, combined with spring and damper elements for automatic adjustment and obstacle detection, enabling comfortable and efficient mowing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver manually adjusts the mowing device to mow close to obstacles, then the mowing can be completed in tight spaces, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The support arm is designed to be movable and adjustable, allowing the scaring unit to dynamically change its position relative to the mower deck. This enables the system to adapt to different working conditions and obstacles automatically, resolving the contradiction between ease of operation and time loss by eliminating manual adjustment requirements
Solution Approach 2:
The system enables self-adjustment of the scaring unit position through the movable support arm mechanism. The device can automatically navigate around obstacles without requiring continuous manual intervention from the driver, thus improving ease of operation while reducing mowing time
2Reliability
If the scaring unit is positioned far from the mower deck, then insects are effectively scared away, but the device complexity and material usage increase
Solution Approach 1:
The support arm provides a dynamic positioning system that allows the scaring unit to maintain the optimal distance from the mower deck. This movable connection enables the system to achieve reliable insect protection while keeping the structure simple and adaptable to different operational requirements
Solution Approach 2:
The support arm is divided into multiple sections or segments that can be independently adjusted. This segmentation allows for flexible positioning of the scaring unit at the required distance from the mower deck while using minimal material and maintaining structural simplicity
