Lawn Mower Blade Sharpening Robot Sensor Feedback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining the sharpness of lawn mower blades are time-consuming and can cause blade degradation, as they require manual removal and repeated measurement to achieve optimal sharpness, leading to excess material removal.
Innovation Solution
A system and method for controlling a blade sharpening and task robot that uses a processor to receive blade data, determine tasks based on sharpness, and perform sharpening or repair operations autonomously using sensors and a task arm, ensuring the blade meets a threshold value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual blade removal and repeated measurement methods are used, then blade sharpness can be determined, but time consumption increases and blade degradation occurs
Solution Approach 1:
The patent replaces manual mechanical measurement methods with an automated sensor-based measurement system. The sensor automatically measures blade sharpness parameters without requiring manual blade removal or repeated measurements, thereby reducing time consumption while maintaining measurement precision.
Solution Approach 2:
The system enables the blade to be measured in situ without removal, allowing the blade to remain in its operational position. The measurement process is self-contained and does not require external manual intervention for blade handling, reducing both time and potential damage from repeated removal and reinstallation.
2Manufacturing precision
If manual blade removal and repeated sharpening operations are performed, then optimal sharpness can be achieved, but excess blade material is removed
Solution Approach 1:
The system continuously monitors blade sharpness parameters and provides real-time feedback to the control system. This feedback mechanism allows for precise control of the sharpening process, stopping exactly when the optimal sharpness is achieved, thereby preventing excess material removal while ensuring the blade reaches the desired sharpness level.
Solution Approach 2:
The automated measurement and control system replaces manual judgment and repeated trial-and-error sharpening operations. The sensor-based system provides objective, precise measurements that guide the sharpening process, eliminating the need for multiple iterations that would otherwise remove excessive blade material.
3Productivity
If automated sensor-based measurement is used, then time efficiency improves, but system complexity increases
Solution Approach 1:
The system introduces a sensor as an intermediary device between the blade and the measurement process. This sensor acts as a mediator that automatically captures blade sharpness data and transmits it to the control system, enabling efficient automated measurement while keeping the added complexity localized to the sensor component rather than the entire system.
