Self-Moving Device Auxiliary Module for Safe Edge Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-moving devices, such as robotic mowers, face challenges in safely cutting to the edges of a working area due to the distance required between the cutting mechanism and the device's perimeter, leading to uncuttable areas and potential safety hazards.
Innovation Solution
A self-moving device equipped with an auxiliary working module, controlled by a wireless communication system, allows for supervised operation via a user terminal, enabling the device to perform auxiliary tasks like trimming and pruning, and switches to a safe mode if the communication is interrupted or out of range, ensuring safety and efficient edge cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protective cover is disposed on the periphery of the cutting system to prevent injury, then user safety is improved, but the distance between the cutting member and the device perimeter increases, creating uncuttable areas
Solution Approach 1:
The cutting system is divided into a main cutting module for general area cutting and an auxiliary cutting module for edge trimming. The main cutting member handles the bulk cutting tasks while the auxiliary cutting member, positioned on the periphery, handles edge cases that the main cutter cannot reach, thus resolving the contradiction between safety distance and cutting coverage.
Solution Approach 2:
The auxiliary cutting module extends the cutting capability to the peripheral dimension of the device. By adding cutting functionality at the device perimeter through the auxiliary cutting member, the system can now cut edges that were previously inaccessible due to the protective cover distance requirement.
2Reliability
If the distance between the cutting member and device perimeter is increased to ensure safety, then user safety is improved, but the ability to cut to edge is reduced
Solution Approach 1:
The cutting function is segmented between a main cutting member positioned centrally for safe operation and an auxiliary cutting member positioned at the periphery for precise edge cutting. This segmentation allows each component to optimize its position for its specific function, resolving the contradiction between safety distance and edge cutting precision.
Solution Approach 2:
The auxiliary cutting module acts as an intermediary between the main cutting system and the device perimeter. It bridges the gap created by the protective cover distance requirement, enabling precise edge cutting without compromising the safety of the main cutting system.
3Ease of operation
If the device operates autonomously without manual intervention, then ease of operation is improved, but safety control in emergency situations is reduced
Solution Approach 1:
The system dynamically switches between autonomous working mode and auxiliary working mode based on real-time conditions. The control module monitors the working environment and automatically adjusts the operation mode, enabling the device to maintain high automation while responding to safety requirements in emergency situations.
Solution Approach 2:
The control module continuously monitors the working conditions and provides feedback to adjust the operation mode. When safety concerns are detected, the system receives feedback and automatically switches from fully autonomous mode to auxiliary mode with enhanced safety controls, thus maintaining both ease of operation and emergency safety control.
