Virtual Keep-Out Zone Broadcasting for Hazard-Aware Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively communicate or broadcast the boundaries of a keep-out-zone to vehicles to prevent them from driving through or in such zones, especially in situations like accidents or construction sites, which can lead to safety hazards.
Innovation Solution
A virtual barrier system that uses a transmitter to broadcast the coordinates of a keep-out-zone to other vehicles, utilizing GPS and sensors to determine and adjust the boundaries dynamically, with optional safety markers to define the zone's perimeter, and integrates with digital maps for real-time updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a keep-out-zone is established to protect vehicles and objects, then safety is improved, but the system complexity increases due to the need for dynamic boundary adjustment and communication
Solution Approach 1:
The system continuously monitors the keep-out-zone boundaries and dynamically adjusts them based on real-time data from door detectors, proximity detectors, and location detectors. This feedback mechanism ensures safety is maintained while automating the complexity of boundary management, reducing the need for manual intervention.
Solution Approach 2:
A transmitter acts as an intermediary to broadcast keep-out-zone boundary information to other vehicles and systems. This mediator component simplifies the overall system architecture by centralizing the communication function, allowing multiple vehicles to receive safety information without requiring direct peer-to-peer communication between all components.
2Reliability
If the keep-out-zone boundaries are dynamically adjusted to accommodate moving vehicles and approaching objects, then safety is improved, but the loss of time increases due to continuous monitoring and adjustment
Solution Approach 1:
The system proactively establishes initial keep-out-zone boundaries before vehicles or objects approach, based on predicted trajectories and pre-defined safety parameters. This preliminary action reduces the need for reactive adjustments, minimizing the time required for continuous monitoring and boundary modification while maintaining safety.
3Reliability
If the keep-out-zone boundaries are expanded to account for approaching objects, then safety is improved, but the loss of time increases due to route adjustments by other vehicles
Solution Approach 1:
The system pre-calculates and broadcasts updated keep-out-zone boundaries before objects actually approach, allowing other vehicles to plan alternative routes in advance. This preliminary notification reduces the need for sudden route changes, minimizing the time loss for other vehicles while maintaining expanded safety boundaries.
