Solution Overview
Problem
Firefighting helicopters and unmanned aircrafts are unable to effectively extinguish fires inside buildings, and existing solutions lack the capability for rapid, early-stage fire suppression and lifesaving measures within confined spaces.
Innovation Solution
A fire extinguishing drone with a ∩-shaped body, integrated propeller units for flight, a disaster prevention turret for chemical spraying and bomb deployment, and servo-motor operated wheels for versatile ground and flight movement, equipped with a CPU and battery for stable operation and lifesaving functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If unmanned aircrafts are used for fire extinguishment, then rapid response is achieved, but fires inside buildings in early stages cannot be extinguished
Solution Approach 1:
The drone's landing gear is designed to be dynamically detachable, allowing rapid transition from flight mode to ground mode. This enables the drone to quickly respond to building fires by flying to the location, then detaching the landing gear to enter the building interior and suppress fires at their early stages
Solution Approach 2:
The drone is designed with multi-functionality to perform both aerial fire suppression and ground-based interior fire suppression. It carries fire extinguishing equipment that can be deployed in both modes, making it a universal firefighting platform that addresses both rapid response and building interior fire suppression needs
2Reliability
If wheels with individual servo-motors are used, then stable movement on uneven surfaces is achieved, but device complexity increases
Solution Approach 1:
The driving system is segmented into four independent wheel units, each with its own servo motor. This segmentation allows each wheel to independently adjust to uneven surfaces, improving stability while keeping each individual motor unit simple and manageable
Solution Approach 2:
Each wheel is equipped with individual servo motors that provide localized control and adaptation to surface conditions. This local quality approach allows the drone to navigate uneven terrain effectively while maintaining a modular architecture that simplifies the overall system design and maintenance

AI summary
The present invention relates to a fire extinguishing firefighting drone which, in case of a fire in a house, a structure, a building, or the like, can be rapidly introduced and extinguish a fire in an early stage of the fire, and can be remotely operated in an unmanned manner through connection with a central control system. The fire extinguishing firefighting drone includes a flight unit configured to include propeller units, a disaster prevention turret unit configured to spray a fire-extinguishing chemical, a plurality of movement units configured to move a body unit, and a disaster prevention means unit configured to be provided with items adapted to spray a fire-extinguishing chemical, to launch a fire-extinguishing bomb, or to save lives.
