Packaging Machine Fault Recovery Using a Shared Knowledge Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic packaging machines face increasing complexity, making it difficult to identify and resolve faults quickly, leading to significant production time losses, as existing diagnostic systems fail to provide precise solutions for all possible issues, and solutions are not recorded or shared across machines.
Innovation Solution
A method that involves creating a data processing system with a knowledge base to identify and store operating variables, problematic conditions, and corresponding solutions, allowing the machine to diagnose faults and provide solutions to operators through an interface, with the ability to learn from operator interactions and update its knowledge base for future reference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the automatic machine increases production volumes and complexity, then productivity is improved, but the difficulty of detecting and measuring faults increases
Solution Approach 1:
The system continuously monitors operating variables and provides feedback to the data processing system, which compares actual values against the knowledge base to automatically detect faults and suggest solutions, resolving the difficulty of fault detection in complex high-productivity machines
Solution Approach 2:
The patent replaces manual fault detection and diagnosis (mechanical/operator-based system) with an automated electronic system that uses sensors, data processing, and knowledge base algorithms to identify and resolve faults, thereby managing complexity while maintaining high productivity
2Ease of operation
If manual fault resolution methods are used, then ease of operation is maintained, but loss of time increases
Solution Approach 1:
The system enables self-service fault resolution by automatically monitoring machine operation, detecting faults through operating variable analysis, and providing diagnostic solutions without requiring extensive operator intervention or manual troubleshooting, thereby reducing downtime while maintaining operational simplicity
Solution Approach 2:
The knowledge base pre-stores diagnostic rules and solutions for various fault conditions, allowing the system to immediately retrieve and present appropriate solutions when faults are detected, eliminating the time required for operators to manually search for troubleshooting information
3Device complexity
If fault solutions are not recorded or shared, then device complexity is reduced, but loss of information increases
Solution Approach 1:
The patent merges individual machine fault solutions into a centralized knowledge base that can be shared across multiple machines, allowing solution information to be accumulated and reused without significantly increasing the complexity of individual machine operations
Solution Approach 2:
The knowledge base serves multiple functions: storing operating variables, recording fault conditions, providing diagnostic solutions, and enabling cross-machine knowledge sharing, thereby preserving valuable information while maintaining a unified, manageable system architecture

AI summary
A method to restore the functional state of an automatic machine for the production or the packaging of consumer products. The method comprises the steps of: storing a first knowledge base containing a plurality of problematic operating conditions having a corresponding known fault; training the data processing system by associating ate least one solution to each problematic operating condition and storing a second knowledge base containing the solution; identifying a current operating condition; searching, among all the problematic operating conditions stored in the first knowledge base, for the problematic operating condition that is the most similar to the current operating condition; and communicating to an operator the solution associated with the corresponding problematic operating condition and stored inside the second knowledge base.
