Solution Overview

Problem

Existing data processing methods for engineering projects, such as P&IDs and CNs, are inefficient as they process data one-by-one, leading to loss of information and inconsistencies due to lack of comprehensive analysis.

Innovation Solution

A large language model-based autonomous agent with domain knowledge representation orchestrates the processing of multiple data types (images and text) using a mixture-of-experts system, ensuring comprehensive and consistent output by aligning and combining results with underlying domain knowledge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If single engineering project data is processed one-by-one using AI/ML models, then processing speed and automation are improved, but information completeness and data consistency deteriorate

Engineering Contradiction:
Improveprocessing speedVSAvoidinformation completeness
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent combines multiple data sources (P&IDs, Control Narratives, IO Lists, Tag Lists, Single line diagrams, functional descriptions, logic diagrams, motor and consumer lists, and instrumentation lists) from the same engineering project into a unified processing framework. This merging allows the system to process all related data together, ensuring information completeness while maintaining automation through the LLM-based autonomous agent that coordinates the integrated processing workflow.

Inventive Principle:
Principle #5Merging (Combining)

2Extent of automation

If single engineering project data is processed one-by-one, then automation is improved, but data consistency and contradiction detection deteriorate

Engineering Contradiction:
Improveautomation levelVSAvoiddata consistency
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the LLM-based autonomous agent comprehensively analyzes processed data to check for contradictions and optimization potential. The system uses this feedback to iteratively refine its processing, ensuring data consistency across all engineering documents. This feedback loop maintains high automation while improving reliability through continuous validation and correction.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The LLM-based autonomous agent acts as an intermediary that coordinates between different data sources and processing tools. It manages the integration of multiple data types, ensures consistent interpretation across documents, and mediates contradiction resolution by analyzing relationships between P&IDs, Control Narratives, IO Lists, and other engineering data, thereby maintaining data consistency throughout the automated process.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If comprehensive analysis of all engineering data is performed, then information completeness and consistency are improved, but processing complexity and resource requirements worsen

Engineering Contradiction:
Improvedata consistencyVSAvoidprocessing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the comprehensive data processing task into manageable components by using the LLM-based autonomous agent to selectively process different data types (P&IDs, Control Narratives, IO Lists, etc.) through appropriate specialized tools. This segmentation reduces processing complexity by breaking down the overwhelming task of analyzing all engineering data into structured, tool-specific processing steps while maintaining comprehensive coverage and data consistency.

Inventive Principle:
Principle #1Segmentation
