Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous operation devices, such as intelligent lawn mowers, often experience operational omissions due to deviations from planned paths caused by uneven terrain or GPS interference, leading to unmown areas and inefficient mowing.
Innovation Solution
An operation method for autonomous operation devices that detects and records omission events by analyzing operational data from inertial and positioning sensors, generating a second electronic map with target coordinates for remedial path planning to minimize missed mowing areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the autonomous operation device operates according to a preset path on uneven terrain or with GPS interference, then the device can maintain autonomous operation, but operational omissions and unmown areas occur due to path deviations
Solution Approach 1:
The system continuously monitors operational data including positioning information and inertial sensor data during mowing operations. When deviations from the preset path are detected or when operational omissions are identified, the system provides feedback to the path planning module, which then generates a remedial path to cover the missed areas, ensuring complete mowing coverage while maintaining autonomous operation
Solution Approach 2:
The system performs preliminary path planning before operation and preliminarily identifies areas that require mowing. When operational omissions occur during execution, the system has already prepared the capability to generate remedial paths, allowing quick correction without manual intervention and maintaining autonomous operation throughout the process
2Device complexity
If the device follows a fixed preset path, then operation planning is simple, but terrain variations and GPS interference cause deviations and unmown areas
Solution Approach 1:
The path planning system transitions from a static preset path to a dynamic adaptive path. The system continuously adjusts the operation path based on real-time positioning data, terrain conditions, and detected operational omissions. The path planning module generates remedial paths dynamically during operation, allowing the device to adapt to terrain variations and GPS interference while maintaining relatively simple operation planning
Solution Approach 2:
The system changes operational parameters including path coordinates, mowing direction, and operation sequence based on detected deviations and unmown areas. When GPS interference or terrain variations cause path deviations, the system modifies path parameters to generate corrected trajectories, improving path following accuracy while keeping the overall planning framework relatively simple
3Ease of operation
If operational omissions are not detected, then the operation process is simple, but unmown areas remain and user trust is reduced
Solution Approach 1:
The system implements continuous feedback monitoring during operation by comparing actual position and mowing coverage against the preset path and planned coverage areas. When operational omissions are detected through this feedback mechanism, the system automatically generates remedial paths to cover missed areas, maintaining operation simplicity while preventing information loss about mowing coverage
Solution Approach 2:
The system performs self-detection of operational omissions and self-correction through automated remedial path generation. The autonomous operation device monitors its own operation status, identifies unmown areas, and independently plans corrective actions without external intervention, maintaining simplicity while ensuring complete coverage information is captured and acted upon
