Wearable Hazard Telemetry for Real-Time Worker Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring and managing workplace hazards in naval industrial facilities and shipyards are inadequate, relying on sporadic assessments by inspectors, leading to inconsistent data collection, delayed communication of safety information, and reliance on individual workers' interpretations, which can result in unsafe conditions and decreased situational awareness.
Innovation Solution
A system comprising wearable devices with integrated environmental and health hazard sensors, a controller for comparing sensor data with safety thresholds, and a transmitter for alerting workers via visual, auditory, or tactile cues, enabling real-time monitoring and personalized safety recommendations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sporadic assessments by inspectors are used, then device complexity is reduced, but measurement precision and reliability of safety data deteriorate
Solution Approach 1:
The wearable device enables workers to self-monitor their own safety metrics continuously without requiring external inspectors. The device autonomously collects, processes, and presents safety data to the wearer in real-time, eliminating dependency on third-party assessment personnel while maintaining high measurement precision through dedicated sensors and processing capabilities.
2Measurement precision
If continuous real-time monitoring is implemented, then measurement precision and timeliness of safety information improve, but device complexity and cost increase
Solution Approach 1:
The wearable device integrates multiple safety monitoring functions into a single universal platform. It simultaneously tracks environmental hazards, personal health metrics, and provides real-time alerts, eliminating the need for separate specialized devices for each function. This multi-functionality reduces overall system complexity while maintaining continuous high-precision monitoring across all safety parameters.
Solution Approach 2:
The device merges environmental sensing, physiological monitoring, data processing, and alert delivery into one integrated wearable unit. By combining previously separate systems (environmental sensors, health trackers, communication modules) into a single device, the solution achieves continuous real-time monitoring without proportionally increasing complexity, as components share common infrastructure like power supply, data processing unit, and display interface.
3Ease of operation
If responsibility for safety monitoring is delegated to inspectors, then ease of operation for workers is improved, but loss of time in communicating safety information increases
Solution Approach 1:
The system implements immediate feedback loops where safety data is continuously collected by sensors, processed by the controller, and presented to the worker in real-time through the display interface. This closed-loop feedback eliminates the time delay inherent in inspector-mediated communication, as workers receive safety information directly and instantly without intermediate transmission steps.
Solution Approach 2:
Workers use the wearable device to self-monitor their own safety status continuously. The device autonomously performs all monitoring and communication functions, eliminating dependency on inspectors for safety information delivery. This self-service approach maintains ease of operation while completely eliminating time delays in safety information communication.
4Ease of operation
If individual workers interpret safety information independently, then ease of operation is improved, but reliability of safety decisions deteriorates
Solution Approach 1:
The device provides workers with autonomous, real-time safety information processing and presentation. Rather than requiring workers to independently interpret complex safety data, the system automatically processes sensor inputs, compares readings against safety thresholds, and presents clear, actionable safety status information to the worker, maintaining autonomy while ensuring reliability through algorithmic consistency.
