Excavator Attachment Control for Precise Work Surface Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing excavators require time and effort to prepare and input data on target work surfaces, which can be challenging for operators, especially those less skilled, leading to inefficiencies in work operations.
Innovation Solution
The excavator system includes a control mode that automatically adjusts the position of the bucket attachment to match predefined work surfaces based on operator input, using proportional valves and a controller to maintain desired angles and positions without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic control mode is implemented to reduce manual intervention, then work efficiency is improved, but device complexity increases
Solution Approach 1:
The system enables self-service operation where the attachment automatically adjusts its own position and orientation based on sensor feedback and control algorithms, eliminating the need for extensive manual intervention while maintaining operational autonomy
Solution Approach 2:
The control system continuously receives feedback from sensors monitoring the attachment's position, orientation, and operational parameters, automatically adjusting control signals to maintain optimal performance without requiring manual recalibration or intervention
2Manufacturing precision
If precise work surface formation is achieved through automatic control, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system replaces manual mechanical operation with automated electronic control and sensor-based positioning, where computer algorithms calculate and execute precise positioning commands, achieving high precision while simplifying the operator's role to monitoring and initiation
3Ease of operation
If data preparation requirements are reduced for operator convenience, then ease of operation is improved, but measurement precision may worsen
Solution Approach 1:
The system automatically collects, processes, and validates work surface data through integrated sensors and control algorithms, eliminating the need for manual data preparation while ensuring precision through automated verification and correction procedures
Solution Approach 2:
The control system performs preliminary data collection and processing operations automatically before actual work begins, including sensor calibration, reference surface establishment, and parameter optimization, so that precise measurements are achieved without requiring manual data preparation
