Solution Overview

Problem

Manufacturing execution systems (MES) lack flexibility and adaptability in data collection plans, which are often rigid and not context-specific, leading to inefficient data collection and maintenance processes in manufacturing environments.

Innovation Solution

A manufacturing execution system that employs context-specific data collection plans, specified by sets of objects for defining limits, sampling, rules, and frequency, allowing for dynamic adaptation and reusability, with a service interface for providing these plans and an analytical component for processing data to trigger maintenance actions when criteria are not met.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If rigid and generic data collection plans are used in manufacturing execution systems, then system simplicity and ease of implementation are improved, but flexibility and adaptability to different manufacturing contexts deteriorate

Engineering Contradiction:

Improveease of implementationVSAvoidflexibility

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic data collection plans that automatically adjust sampling rates and parameters based on real-time manufacturing context, equipment state, and product specifications. The system transitions from static, rigid plans to dynamic, adaptive plans that respond to changing conditions, resolving the contradiction between implementation simplicity and operational flexibility.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes data collection parameters (sampling rates, data types, collection frequency) based on manufacturing context, product criticality, and process stability. By allowing parameter adaptation without redesigning the entire data collection framework, the system maintains ease of implementation while gaining flexibility.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If context-specific data collection plans with multiple parameters and objects are implemented, then flexibility and adaptability are improved, but system complexity and configuration difficulty increase

Engineering Contradiction:

ImproveflexibilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the data collection plan into distinct, reusable parameter objects (sampling parameters, data type parameters, frequency parameters). Each parameter is an independent, configurable object that can be selectively applied to different manufacturing contexts, reducing overall system complexity through modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system creates universal parameter objects that can be reused across multiple data collection plans and manufacturing contexts. A single sampling parameter object can serve multiple products, processes, and equipment types, reducing complexity through reuse rather than duplication.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If default data collection plans are used for all manufacturing steps, then system simplicity is maintained, but productivity and manufacturing efficiency deteriorate due to inefficient data collection

Engineering Contradiction:

Improvesystem simplicityVSAvoidmanufacturing efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent applies local quality by tailoring data collection parameters to specific manufacturing steps, products, and equipment based on their unique requirements. Critical processes receive higher sampling rates and more detailed data collection, while stable processes use reduced sampling, optimizing productivity without uniformly increasing system complexity.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system applies partial data collection by selecting only the necessary parameters and sampling rates for each specific manufacturing context. Instead of collecting all possible data uniformly, the system collects only what is needed for each process, improving productivity by reducing unnecessary data collection overhead.

Inventive Principle:

Principle #16Partial or excessive action
