Modular Machine Recovery Through Autonomous Module Swapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial machines in factories face significant downtime and production delays due to failures in support systems, which can be exacerbated by proactive replacement of components before they fail, leading to wastage and incomplete mitigation of unexpected failures.
Innovation Solution
Implementing a system where autonomous vehicles receive status messages from programmable logic controllers (PLCs) to identify faulty modules, autonomously remove and replace them with spare modules, allowing the machine to recover from shutdown to full operating mode with minimal downtime, and utilize pre-defined routes and quick release couplings for efficient module swapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proactive replacement of system components is implemented, then reliability is improved, but loss of time increases due to unplanned downtime and component wastage
Solution Approach 1:
The system performs preliminary actions by proactively identifying components that are likely to fail based on predictive analytics and sensor data. Replacement components are prepared in advance and staged for immediate installation, eliminating the need for unplanned downtime when failures occur.
Solution Approach 2:
The system enables self-service through automated monitoring, diagnosis, and replacement processes. The machine can identify its own faults, order replacement components, and perform swaps with minimal human intervention, reducing overall downtime and improving response speed.
2Ease of operation
If traditional manual replacement methods are used, then ease of operation is maintained, but productivity decreases due to extended downtime and manual intervention requirements
Solution Approach 1:
The system replaces manual mechanical replacement operations with automated robotic systems. Robots perform the physical removal and installation of components, while automated systems handle diagnostics, component ordering, and system reconfiguration, dramatically reducing replacement time and maintaining ease of operation through centralized control.
Solution Approach 2:
The system introduces an intermediary automated replacement system that acts as a mediator between the faulty component and the replacement component. This intermediary system coordinates the entire replacement process, including diagnostics, component retrieval, installation, and system verification, improving both productivity and ease of operation.
3Reliability
If complete system shutdown is implemented for module replacement, then reliability is improved by preventing further damage, but loss of time increases due to full operational interruption
Solution Approach 1:
The system extracts the faulty component from the operating system, allowing the remainder of the machine to continue functioning. By isolating and removing only the problematic module rather than shutting down the entire system, minimal downtime is achieved while maintaining reliability through immediate replacement capability.
Solution Approach 2:
The system segments the machine into independent modular components that can be replaced individually. This segmentation allows the replacement of specific faulty modules without affecting the operation of other modules, thereby maintaining overall system reliability while minimizing operational downtime.

AI summary
Systems and methods are described for autonomously recovering a machine comprising one or more modules. An error message from the machine is received and, based on the error message, a first module of the one or more modules to replace is determined, wherein the first module has a first type. An autonomous vehicle is instructed to remove, from the machine, the first module. The autonomous vehicle is instructed to install, at the machine, a second module of the first type.
