Laser Keep-Out Zone Monitoring for Construction Intrusion Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety monitoring systems for construction sites fail to effectively alert workers and stakeholders about potential hazards and unauthorized intrusions in protected areas, leading to increased risks of accidents and unsafe conditions.
Innovation Solution
A safety monitoring system comprising portable electronic monitoring devices that generate alerts and notifications using audio, visual, and electronic signals to detect intrusions and monitor atmospheric conditions, coupled with a central server for data analysis and alarm generation, ensuring real-time situational awareness and safety protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional safety monitoring systems are used, then system simplicity is maintained, but worker safety and hazard detection effectiveness deteriorate
Solution Approach 1:
The safety monitoring system is divided into multiple independent monitoring devices distributed throughout the construction site, each capable of autonomous detection and alert generation. This segmentation allows the system to cover large areas effectively while maintaining manageable complexity through modular design.
Solution Approach 2:
The monitoring devices are designed to perform multiple functions including intrusion detection, atmospheric condition monitoring, worker location tracking, and emergency alert generation. This multi-functionality consolidates what would otherwise require multiple separate systems into a unified platform, improving reliability without proportionally increasing complexity.
2Loss of information
If real-time monitoring of all workers is implemented, then safety awareness is improved, but information processing load increases
Solution Approach 1:
The system processes and analyzes safety information locally at each monitoring device rather than centralizing all data processing. Each device independently evaluates its sensor data and generates alerts only when specific safety thresholds are breached, reducing the information processing load on central systems while maintaining comprehensive safety monitoring.
Solution Approach 2:
The monitoring devices provide continuous feedback to workers through audible and visual alerts when safety conditions are compromised. This immediate feedback loop ensures safety information is communicated in real-time without requiring complex centralized analysis, as each device autonomously determines when alert conditions are met.
3Reliability
If multiple alert mechanisms are deployed, then hazard notification effectiveness is improved, but energy consumption increases
Solution Approach 1:
The monitoring devices operate in periodic cycles, alternating between low-power standby mode and active monitoring/alert modes. Alerts are generated periodically only when safety conditions require intervention, rather than continuously operating at full power. This periodic operation maintains effective hazard notification while significantly reducing overall energy consumption compared to continuous high-power operation.
