Deployable Warning Perimeter Around Vehicles Without Roadside Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of vehicles that frequently park along roads or are dispatched to scenes face safety risks when placing warning devices, as they must walk along busy highways to make the vehicle and scene visible, increasing the risk of being struck.
Innovation Solution
A deployable device system comprising a deployable device with a propulsive element, a motor, and an indicator, which can be automatically deployed around a vehicle to establish a perimeter and provide warnings to approaching vehicles, thereby enhancing visibility and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the operator manually places warning devices around the vehicle, then the visibility of the vehicle and scene is improved, but the safety of the operator deteriorates due to increased risk of being struck by oncoming vehicles
Solution Approach 1:
The deployable device autonomously deploys itself around the vehicle using its propulsive element and motor, without requiring the operator to manually place warning devices. The device navigates independently to establish a perimeter and provides visual indications through its indicator, making the system self-sufficient and eliminating the need for operator exposure to traffic hazards.
Solution Approach 2:
The deployable device acts as an intermediary between the operator and the external environment. It assumes the dangerous task of being positioned around the vehicle on the roadway, serving as a mediator that protects the operator from direct exposure to oncoming traffic while still providing the necessary warning functions.
2Loss of information
If the operator walks along busy highways to place warning devices, then the presence of the vehicle and scene becomes visible to oncoming traffic, but the operator's exposure to harmful factors increases
Solution Approach 1:
The deployable device independently performs the function of establishing visibility without human intervention. It uses its propulsive element to move into position and its indicator to provide visual warnings, making the system self-sufficient and eliminating the need for operator exposure to traffic hazards.
Solution Approach 2:
The patent replaces the mechanical action of the operator walking and placing devices with an automated propulsive system. The motor-driven propulsive element substitutes for manual mechanical placement, and the electronic indicator substitutes for manual positioning of traditional warning devices.
3Illumination intensity
If multiple deployable devices are deployed around the vehicle, then the visibility and safety perimeter is enhanced, but the complexity of the system increases
Solution Approach 1:
The warning system is divided into multiple independent deployable devices, each capable of autonomous operation. This segmentation allows the system to create a comprehensive perimeter around the vehicle while maintaining simplicity at the individual device level. Each unit is a self-contained module that can be independently controlled and positioned.
Solution Approach 2:
The deployable device is designed as a multi-functional unit that combines propulsion, positioning, and visual indication capabilities in a single integrated system. This universality reduces overall system complexity by eliminating the need for separate components for each function, while still enabling comprehensive coverage when multiple units are deployed.

AI summary
A deployable device system including a deployable device, a vehicle, and a control system. The deployable device includes a propulsive element coupled to the deployable device, a motor coupled to the deployable device and the propulsive element and configured to drive the propulsive element to propel the deployable device, and an indicator configured to provide one or more indications to an operator of an approaching vehicle. The vehicle is configured to transport the deployable device to a scene and deploy the deployable device. The control system is configured to control the motor to position the deployable device at a position along a perimeter established proximate the scene, and control the indicator to provide an indication.
