Solution Overview

Problem

Stranded vehicles can be difficult for service truck drivers and emergency personnel to locate, especially at night or in low visibility conditions, due to their unattended and unmarked status on the side of the road.

Innovation Solution

A drone deployment system integrated into a host vehicle that deploys an unmanned aerial vehicle (UAV) equipped with lights and a siren, which can hover above the vehicle and follow it, providing visual and auditory alerts to draw attention and facilitate location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a drone is deployed from a stranded vehicle to provide visual and auditory alerts, then the visibility and accessibility of the vehicle is improved, but the device complexity and safety risks increase

Engineering Contradiction:
Improvevisibility of stranded vehicleVSAvoiddrone deployment system
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The drone is nested within the vehicle's trunk or storage compartment, allowing it to be stored compactly and deployed when needed. The drone housing integrates with the vehicle structure, and the deployment mechanism uses the vehicle's existing spatial architecture to minimize added complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The drone serves multiple functions: it provides visual alerts through lights, auditory alerts through sirens, and can act as a communication device. This multi-functionality justifies the added device complexity by delivering comprehensive alert capabilities from a single integrated system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If a drone is deployed to hover above and follow the host vehicle, then the alert effectiveness is improved, but the energy consumption and operational reliability concerns increase

Engineering Contradiction:
Improvealert delivery effectivenessVSAvoiddrone energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The drone operates in periodic cycles, alternating between hovering above the vehicle and returning to the storage compartment. This periodic operation reduces continuous energy consumption while maintaining effective alert delivery, as the drone can serve multiple vehicles or extend its operational pattern over time.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The drone's operational mode is dynamic, adjusting between hovering, following, and returning based on mission requirements and energy status. This dynamic operation optimizes energy usage by adapting the drone's behavior to current conditions rather than maintaining a fixed operational state.

Inventive Principle:
Principle #15Dynamics

3Difficulty of detecting and measuring

If the drone is equipped with lights and siren to draw attention, then the detection capability is improved, but the object-generated harmful factors increase

Engineering Contradiction:
Improvedetectability of stranded vehicleVSAvoidnoise and light pollution
Core Design Contradiction:
Difficulty of detecting and measuringVSObject-generated harmful factors

Solution Approach 1:

The lights and siren are directed locally toward the stranded vehicle and surrounding area, concentrating the alert effect where needed rather than creating widespread noise and light pollution. The directional nature of the alerts minimizes harmful effects on unrelated areas while maintaining high detectability of the target vehicle.

Inventive Principle:
Principle #3Local quality
