Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If process automation and electrical automation systems are kept separate, then system simplicity is maintained, but integration and coordination between the two systems are insufficient

Engineering Contradiction:
Improveintegration capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a gateway device as an intermediary between the process automation system and electrical automation system. This gateway translates data between different protocols (IEC 61850 and Ethernet/IP) and formats, enabling seamless communication without requiring direct integration between the two systems. The gateway handles data conversion, scaling, and protocol translation, thus improving integration capability while maintaining relative simplicity of the core systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If data translation and processing functions are added to interface the systems, then data compatibility is improved, but the complexity of the interfacing apparatus increases

Engineering Contradiction:
Improvedata compatibilityVSAvoidinterfacing apparatus complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functions (protocol translation, data scaling, format conversion, and timing synchronization) into a single gateway device. This consolidation improves data compatibility across systems while managing complexity by integrating rather than multiplying separate components. The gateway executes add-on instructions to perform multiple data processing operations in one unified apparatus.

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If high accuracy timing is implemented for synchronization, then coordination precision is improved, but the complexity of timing mechanisms increases

Engineering Contradiction:
Improvetiming precisionVSAvoidtiming mechanism complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements a timing synchronization mechanism where the gateway receives timing information from both the process automation system and electrical automation system, compares them, and adjusts data transmission timing accordingly. This feedback-based approach achieves high timing precision for coordinated energy management and control decisions without requiring complex hardware modifications to the core systems.

Inventive Principle:
Principle #23Feedback
