Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional automation control systems are used to manage device operations, then basic control functions are achieved, but safety control and monitoring of personnel and object positions and motions are insufficient

Engineering Contradiction:
Improvesafety controlVSAvoidmonitoring capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The automation control system is enhanced with multi-functional capabilities by integrating motion detection, position tracking, and hazard prediction functions into the existing control architecture. The system simultaneously performs traditional control tasks and new safety monitoring tasks using shared hardware resources and coordinated processing modules.

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

Solution Approach 2:

Motion sensors and detection devices are introduced as intermediary components between the control system and the industrial environment. These intermediaries capture motion data and position information, which are then processed by the control system to generate safety decisions, enabling enhanced monitoring without directly modifying core control functions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If motion detection and position monitoring are added to enhance safety, then hazard prediction capability is improved, but system complexity increases

Engineering Contradiction:
Improvehazard predictionVSAvoidsystem architecture
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple safety functions including motion detection, position monitoring, and hazard prediction are merged into a unified control module. This integration shares processing resources and data pathways, reducing the overall system complexity that would result from completely separate systems for each function.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system performs self-monitoring and self-adjustment by automatically analyzing motion data and position information to predict hazards and adjust control parameters without external intervention. This self-service capability reduces the need for additional external monitoring equipment and simplifies the overall system architecture.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If range camera systems are integrated for detecting positions and motions, then monitoring precision is enhanced, but device complexity and cost increase

Engineering Contradiction:
Improveposition and motion detection accuracyVSAvoidhardware integration
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The range camera system is designed to serve multiple functions including position detection, motion tracking, and hazard prediction simultaneously. By making the detection system multi-functional, the need for separate specialized devices is reduced, offsetting the complexity increase through resource consolidation.

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

Solution Approach 2:

Traditional mechanical position sensors and motion detectors are replaced with optical range camera systems that use light-based measurement techniques. This substitution achieves higher precision with non-contact measurement, eliminating the need for physical sensors on monitored objects and reducing mechanical system complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The present disclosure generally relates to a method for performing industrial automation control in an industrial automation system which may include detecting, via a sensor system, positions and/or motions of one or more humans and/or one or more objects in an industrial automation system and distinguishing, via a programmed computer system, between one or more humans and one or more objects based upon the detected positions and/or motions. The method may then include implementing a control and/or notification action based upon the distinction.
