Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current excavation vehicles require manual operation of separate tilt switches and use position measuring devices and laser feedback for precise positioning, which is cumbersome and increases the risk of vehicle instability during operations.
Innovation Solution
A tilt-compensation system that detects vehicle tilt angles and calculates tilt-compensated position outputs for the boom, stick, and bucket, automatically adjusting their positions to ensure safe and accurate operation by integrating position detection, analysis, and correction modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual operation of separate tilt switches and position measuring devices is used, then positioning accuracy can be achieved, but device complexity and operational burden increase
Solution Approach 1:
The patent combines multiple separate tilt switches and position measuring devices into a single integrated tilt compensation system. The system uses a single tilt sensor to detect vehicle tilt angle, which then automatically compensates for positioning across all excavation vehicle components (boom, stick, bucket), eliminating the need for separate tilt switches for each component and reducing overall system complexity while maintaining positioning accuracy.
Solution Approach 2:
The tilt compensation system serves multiple functions simultaneously: it monitors vehicle tilt angle, calculates compensated positions for all components, and adjusts positioning automatically. This multi-functional approach replaces multiple dedicated devices with one universal system that handles positioning correction for the entire excavation vehicle.
2Measurement precision
If separate tilt switches and laser feedback are used for each component, then positioning precision is maintained, but ease of operation deteriorates
Solution Approach 1:
The tilt compensation system operates automatically without requiring manual intervention. The system self-monitors vehicle tilt through the tilt sensor, self-calculates compensated positions using the detected tilt angle, and self-adjusts component positioning automatically. This eliminates the need for operators to manually operate separate tilt switches and laser feedback devices, greatly improving ease of operation while maintaining positioning precision.
Solution Approach 2:
The system implements automatic feedback control by continuously monitoring vehicle tilt angle through the tilt sensor and using this information to dynamically adjust component positions. The feedback loop automatically compensates for tilt effects without requiring manual operator input, maintaining precision while simplifying operation.
3Reliability
If manual tilt switch operation is used, then vehicle stability monitoring is possible, but reliability decreases due to human error
Solution Approach 1:
The tilt compensation system automatically monitors vehicle stability without requiring manual operation. The tilt sensor continuously detects vehicle tilt angle, and the control system automatically determines whether stability limits are exceeded, eliminating human error and improving reliability of stability monitoring.
Solution Approach 2:
The system provides continuous automatic feedback on vehicle stability by monitoring tilt angle through the sensor and comparing it against safety thresholds. This automated feedback mechanism ensures reliable stability monitoring without dependence on manual operator attention or action.
