Solution Overview

Problem

Existing integrated control and safety systems in industrial facilities rely on static sensing systems and predefined responses, which are inflexible, non-robust, and inefficient, leading to inadequate monitoring and response to safety hazards, particularly in dynamic environments where personnel movement and equipment operation pose challenges.

Innovation Solution

The implementation of intelligent industrial facility safety systems using remote sensing devices (RSDs) that include fixed and mobile units with sensing, processing, communication, and alert capabilities, configured in various communication schemes to provide robust and adaptive safety monitoring and alerting, enabling dynamic adjustment of sensor deployment and alert prioritization based on real-time data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If fixed sensors are distributed throughout the facility to provide balanced coverage, then monitoring coverage is improved, but the ability to provide heightened monitoring in areas with more personnel is worsened

Engineering Contradiction:
Improvesensor coverage areaVSAvoidadaptive monitoring capability
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The patent implements mobile sensors that can dynamically relocate to different areas of the facility based on real-time personnel location data and hazard risk assessments. This transforms the static sensor deployment into a dynamic system that adapts its coverage areas, allowing heightened monitoring in high-risk zones while maintaining comprehensive facility-wide coverage through coordinated movement of multiple sensors.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The sensor system is divided into multiple independent mobile units that can operate autonomously or in coordination. Each sensor unit can independently navigate and monitor its assigned zone, allowing the system to provide both comprehensive coverage through distributed sensors and heightened monitoring in specific areas by concentrating multiple sensors where needed.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If sensors rely on direct communication with a centralized controller, then system simplicity is improved, but monitoring robustness is worsened when sensors lose communication

Engineering Contradiction:
Improvecommunication architectureVSAvoidmonitoring continuity
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent combines centralized controller architecture with distributed autonomous capabilities in mobile sensors. Each mobile sensor maintains independent hazard detection and local alerting functionality, allowing it to continue monitoring and reporting even when communication with the centralized controller is lost. The centralized controller coordinates overall system operation but the mobile sensors' autonomy ensures monitoring robustness during communication disruptions.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If fixed sensors provide partial coverage of an area, then device complexity is reduced, but the ability to pinpoint event location and provide precise alerts is worsened

Engineering Contradiction:
Improvesensor deploymentVSAvoidevent location accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

Mobile sensors dynamically navigate to and concentrate in areas where hazards are detected or where personnel are located, providing high-resolution monitoring of specific zones. This dynamic positioning allows the system to achieve precise event location identification without requiring a dense fixed sensor network throughout the entire facility, as sensors can be concentrated where needed based on real-time conditions.

Inventive Principle:
Principle #15Dynamics
