Solution Overview
Problem
Existing systems lack effective methods to dynamically control vehicle lighting and aerial devices to establish a safe perimeter at emergency or work sites, potentially risking bystanders and equipment due to inadequate coordination and control of lighting and lift operations.
Innovation Solution
A vehicle system incorporating portable beacon devices and a control system that communicate via wireless protocols to coordinate vehicle lighting, aerial device operations, and establish a virtual boundary, ensuring safe operation and alerting bystanders through synchronized lighting patterns and alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle lighting and aerial devices are operated independently without coordination, then operational flexibility is maintained, but safety risks increase due to lack of perimeter control and bystander protection
Solution Approach 1:
The patent combines vehicle lighting devices, aerial devices, and portable beacon devices into a coordinated system controlled by a central controller. This merging of previously independent operations creates a unified perimeter control system that enhances safety through synchronized lighting patterns and coordinated aerial device movement within defined boundaries.
Solution Approach 2:
The system implements feedback mechanisms where the controller continuously monitors the positions of portable beacon devices and vehicle components, and adjusts lighting patterns and aerial device operations accordingly. This feedback loop ensures that the aerial device remains within safe boundaries while maintaining operational flexibility.
2Object-affected harmful factors
If portable beacon devices are deployed to establish a perimeter, then bystander safety is improved, but system complexity increases due to wireless coordination requirements
Solution Approach 1:
The controller serves as an intermediary that receives wireless signals from portable beacon devices and translates them into coordinated vehicle responses. This intermediary function simplifies the overall system architecture by centralizing the wireless communication handling and converting it into actionable control signals for lighting and aerial devices.
Solution Approach 2:
The controller performs multiple functions including receiving wireless signals from beacons, processing position data, coordinating lighting patterns, and controlling aerial device movement. This multi-functionality reduces the need for separate dedicated systems for each function, thereby managing complexity while providing comprehensive perimeter protection.
3Illumination intensity
If lighting devices are coordinated in synchronized patterns, then perimeter visibility and alerting effectiveness are enhanced, but energy consumption increases
Solution Approach 1:
The system employs periodic lighting patterns where lights alternate between different states (on/off, different intensities, different colors) in synchronized sequences. This periodic action enhances perimeter visibility and creates alerting effects while allowing energy-consuming lights to remain off during non-critical periods, thereby managing overall energy consumption.
Solution Approach 2:
The coordinated lighting system applies different lighting intensities and patterns to different locations around the perimeter based on local requirements. Areas with higher bystander activity or greater safety risks receive enhanced illumination, while less critical areas use reduced lighting, optimizing energy distribution across the perimeter.
