Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In grass mowing operations using a rotationally driven mowing blade, efficiently maintaining the optimal rotation direction for both forward and backward paths is challenging, leading to reduced operational efficiency due to the need to reverse the machine direction.
Innovation Solution
A work vehicle equipped with a traveling machine body and a grass mowing device, where the rotation direction of the rotary mowing blade is automatically switched when the advancing direction of the traveling machine body changes, allowing continuous optimal mowing direction without reversing the machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mowing blade rotates in only one direction during work, then the structure is simple, but the machine direction must be reversed between outward and return paths which lowers operation efficiency
Solution Approach 1:
The patent applies dynamics by making the mowing blade rotation direction changeable based on operating conditions. The rotation direction is dynamically adjusted according to whether the machine is moving forward or backward, allowing optimal mowing performance in both directions while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent changes the rotation direction parameter of the mowing blade based on the machine's advancing direction. By detecting whether the machine moves forward or backward and相应ly adjusting the rotation direction of the mowing blade, the system achieves efficient mowing in both directions without requiring complex mechanical reversing mechanisms.
2Productivity
If the machine direction is reversed between outward and return paths, then the mowing blade can maintain optimal rotation direction, but the reversing operation lowers work efficiency
Solution Approach 1:
The patent enables continuous useful action by allowing the mowing blade to rotate in the optimal direction during both forward and backward movement. The automatic detection and adjustment of rotation direction based on advancing direction eliminates idle time during direction changes, ensuring the mowing operation continues efficiently without interruption.
Solution Approach 2:
The patent replaces mechanical direction reversal with a control system that adjusts the rotation direction of the mowing blade through electrical or hydraulic means. This substitution eliminates the need for physical machine reversal, reducing time loss and improving work efficiency while maintaining optimal mowing conditions.
3Productivity
If automatic switching of rotation direction is implemented, then work efficiency is improved, but the control system becomes more complex
Solution Approach 1:
The patent implements feedback by detecting the advancing direction of the machine and using this information to automatically adjust the rotation direction of the mowing blade. The control system continuously monitors the machine's movement state and相应ly adjusts the blade rotation to maintain optimal mowing conditions, achieving automatic switching with minimal complexity.
