Solution Overview

Problem

Traditional MB-DMI systems fail to effectively map and index data associated with the product lifecycle, leading to inefficiencies and errors in manufacturing and inspection processes.

Innovation Solution

A MB-DMI system that utilizes a data model to integrate and organize product information through FAE addresses, grouping trees, and PMI data, enabling seamless data transfer and automation across the product lifecycle stages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional MB-DMI systems are used without a structured data model, then the system implementation is simpler, but data mapping and indexing efficiency deteriorates leading to errors in manufacturing and inspection processes

Engineering Contradiction:

Improvedata transfer efficiencyVSAvoiddata model structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The data model segments product lifecycle information into hierarchical levels (product level, component level, feature level) using a tree structure. Each level contains specific data elements that can be independently managed and processed, improving data organization and retrieval efficiency without overwhelming system complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The structured data model acts as an intermediary layer between design software and manufacturing/inspection systems. It standardizes data exchange formats and provides consistent data indexing, enabling efficient information flow across different stages of the product lifecycle while maintaining system compatibility

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If traditional MB-DMI systems are used without structured data organization, then the implementation is faster, but error reduction and information consistency deteriorates across product lifecycle stages

Engineering Contradiction:

Improveinformation consistencyVSAvoiddata organization time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The data model establishes predefined structures, relationships, and validation rules before data is entered into the system. Data elements are pre-categorized into hierarchical groups with defined attributes, ensuring consistency from the outset and reducing errors in manufacturing and inspection processes

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system incorporates validation mechanisms that provide feedback when data does not conform to the structured model requirements. This ensures data integrity across product lifecycle stages by automatically detecting and correcting inconsistencies, maintaining reliability without manual verification

Inventive Principle:

Principle #23Feedback

AI summary

A computer system includes a controller having a computer readable storage medium having program instructions embodied therewith, the program instructions executable by controller to perform operations including generating a three-dimensional (3D) model of a product, extracting data indicative of one or more elements of the product, and assigning a FAE address to the one or more elements. The method further includes generating a grouping tree to organize the extracted elements, each extracted element organized according to the FAE address, and adding product and manufacturing information (PMI) data to one or more of the addressed FAEs in the grouping tree.
