Industrial Virtual Assistant for Natural Language Facility Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial facilities face challenges due to a decline in knowledgeable operational staff, with older staff retiring and taking operational knowledge with them, and outdated technology that requires complex user interfaces and hard-coded rules for error detection, making it difficult to transfer knowledge effectively to less experienced staff.
Innovation Solution
A distributed Industrial Virtual Assistant (IVA) platform that allows natural language conversations for operational staff to interact with industrial facilities, utilizing a facilities asset database, domain-specific knowledge databases, natural language processing, and machine learning algorithms to update knowledge databases and adapt to changing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional user interfaces with graphs, dashboards, and menu systems are used, then comprehensive control and monitoring capabilities are achieved, but the ease of operation deteriorates due to complex navigation and extensive training requirements
Solution Approach 1:
The patent replaces traditional mechanical/graphical user interfaces with voice-based natural language processing. Instead of navigating complex menus and dashboards, users speak conversational queries that the system interprets and acts upon, substituting the mechanical interaction paradigm with speech-based interaction.
Solution Approach 2:
The virtual assistant acts as an intermediary between the user and the complex facility management systems. It translates natural language queries into system commands and presents information in conversational form, mediating between the user's simple intent and the complex underlying systems.
2Adaptability or versatility
If hard-coded rules are used for error detection, then systematic monitoring is achieved, but the adaptability deteriorates when new incident types or complex situations arise
Solution Approach 1:
The system transitions from static hard-coded rules to dynamic machine learning models that continuously learn from new data. The incident detection rules are no longer fixed but adapt over time based on patterns learned from historical and real-time facility data, enabling the system to handle new incident types without manual reprogramming.
Solution Approach 2:
The system performs self-learning and self-updating through machine learning algorithms that automatically improve incident detection capabilities. Instead of requiring manual updates to rules by domain experts, the system autonomously learns from data patterns and refines its detection logic.
3Loss of information
If domain experts interpret hard-coded rules to determine cause and solution, then accurate incident analysis is achieved, but the loss of information worsens when experts retire and knowledge is not transferable
Solution Approach 1:
The system captures and stores the implicit knowledge of domain experts by training machine learning models on their interpretations and decisions. This creates a digital copy of expert knowledge that persists beyond individual experts' careers, allowing less experienced staff to access expert-level insights without direct mentorship.
Solution Approach 2:
The system implements continuous feedback loops where incident outcomes and resolutions are fed back into the machine learning models, refining the captured expert knowledge over time. This ensures the knowledge base evolves and improves based on real-world results.
4Ease of operation
If simplified user interfaces are used, then ease of operation improves, but the measurement precision worsens in detecting complex incident anomalies
Solution Approach 1:
The patent replaces complex graphical analysis tools with voice-based natural language processing combined with advanced machine learning. Users can query complex incident patterns through simple speech, while the underlying ML models perform sophisticated analysis to maintain high detection precision.
Solution Approach 2:
The system changes the parameter of interaction from complex graphical manipulation to simple voice commands, while simultaneously enhancing the analytical capabilities through machine learning to compensate for the simplified interface. The ML models process multiple data parameters simultaneously to maintain detection precision.

AI summary
A distributed Industrial Virtual Assistant (IVA) platform and method that that allows operational staff at industrial facilities to have natural language conversations with an IVA to obtain information about, and to control operations of, industrial facilities. For each facility, the IVA platform contains a facilities asset database, one or more domain-specific knowledge databases, a natural language processing engine, and machine learning algorithms for both knowledge domains and context which update the domain-specific knowledge databases based on continuing interactions with operational staff over time. The IVA platform is capable of generating user-specific and device-specific IVA instances that can be queried by voice or text independently of the platform but can connect to the platform to update the databases based on new knowledge, exceptions, and incidents.
