Autonomous Machine Rescue Dispatch for Non-Travelable Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rescue systems for autonomous working machines require human intervention or are limited in their ability to perform rescue operations when machines are unable to travel autonomously, especially when they are not within a reasonable distance from each other.
Innovation Solution
A rescue system comprising autonomous working machines equipped with self-location identification, autonomous travel possibility determination, and management devices that dispatch other machines for rescue, using different self-location identification techniques and towing capabilities to facilitate rescue and recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If human operators manually operate trapped moving bodies using remote-control devices, then the moving bodies can be rescued from abnormal conditions, but human resources are required and increase operational complexity
Solution Approach 1:
The patent enables autonomous working machines to perform self-diagnosis and self-rescue operations. When a machine encounters an abnormal condition, it automatically transmits location information and receives rescue instructions from the management server, eliminating the need for human operators to manually intervene and reducing operational complexity while maintaining rescue capability
Solution Approach 2:
The management server acts as an intermediary between autonomous working machines. It receives abnormal condition information from machines, determines appropriate rescue methods, and transmits rescue instructions back to the machines. This automated mediation system replaces human operators and reduces operational complexity while ensuring reliable rescue operations
2Extent of automation
If autonomous working machines perform rescue operations, then human resources are reduced, but the machines must be within a reasonable distance from each other to detect abnormalities
Solution Approach 1:
The patent replaces direct mechanical proximity-based detection with communication-based detection. Autonomous working machines transmit abnormal condition information and location data through communication devices to the management server, which can then dispatch any machine with appropriate rescue capabilities regardless of physical distance. This substitution of communication for mechanical proximity extends the rescue range while maintaining autonomous operation
Solution Approach 2:
The system transitions from spatial proximity-based rescue (requiring machines to be physically close) to information-based rescue (using communication networks). By adding the communication dimension, the management server can receive and process information from machines anywhere in the network coverage area, effectively extending the rescue range beyond physical proximity constraints
3Adaptability or versatility
If the management device dispatches rescue machines based on location information, then rescue operations can be performed remotely, but communication systems and location tracking are required
Solution Approach 1:
The management server performs multiple functions: it manages autonomous working machines, receives abnormal condition information, determines rescue methods, transmits rescue instructions, and tracks location information. By consolidating these diverse functions into a single multi-functional system, the patent extends rescue range remotely while avoiding the need for multiple separate complex systems
4Loss of energy
If autonomous working machines transmit location information intermittently, then communication bandwidth is reduced, but rescue response time may be delayed
Solution Approach 1:
The patent implements intermittent transmission of location information rather than continuous transmission. Machines transmit location data at specific intervals or when triggered by events, which reduces communication energy consumption. The management server compensates for the intermittent nature by maintaining records and using the most recent information for rescue dispatch, balancing energy efficiency with acceptable response time

AI summary
A rescue system includes a plurality of autonomous working machines and a management device capable of communicating with each of the autonomous working machines, each of the autonomous working machines includes self-location identification means for identifying a self-location of the autonomous working machine, and autonomous travel possibility determination means for determining whether the autonomous working machine can travel autonomously based on a result of identification by the self-location identification means, and the management device includes rescue dispatch means for dispatching an autonomous working machine to the rescue of another autonomous working machine which is determined by the autonomous travel possibility determination means as being in a state of being unable to travel autonomously.
