Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data communication and processing are handled directly by control units in complex automation systems, then control functionality is maintained, but computing loads increase and impair the automation process

Engineering Contradiction:
Improveautomation processVSAvoidcomputing load
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent extracts data communication and processing functions from the control units and relocates them to a separate message distributor module in an external data infrastructure. This allows control units to focus on control tasks while the message distributor handles communication overhead, reducing computing loads on control units and preventing impairment of the automation process.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The message distributor module acts as an intermediary between control units, field devices, and other communication participants. It mediates data exchange, manages communication networks, and handles message routing, thereby reducing the communication burden on control units and improving overall system efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple control units communicate directly with each other in complex automation systems, then data exchange is achieved, but network management complexity increases

Engineering Contradiction:
Improvedata communicationVSAvoidnetwork management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The message distributor module provides universal communication services to all control units and field devices. It handles message routing, network management, and data exchange protocols centrally, allowing diverse communication participants to interact through a unified interface. This multi-functional approach simplifies network management while maintaining high adaptability for different communication scenarios.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If control units process all incoming and outgoing data, then data communication is maintained, but control effectiveness decreases due to computing demands

Engineering Contradiction:
Improvecontrol processVSAvoidcomputing capacity
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent segments the automation system into distinct functional components: control units responsible for control decisions, a message distributor module for communication management, and field devices for data acquisition and actuation. This segmentation allows each component to specialize in its core function, with the message distributor handling data processing tasks that would otherwise consume valuable computing capacity in control units, thereby improving control effectiveness.

Inventive Principle:
Principle #1Segmentation
