Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firefighting drones are limited by their power source capacity, restricting their flight time and ability to completely extinguish fires in high-rise buildings.
Innovation Solution
A fire fighting system that includes a fire hose with a nozzle, a fire-extinguishing liquid supply source, a top drone coupled to the nozzle, and a wired cable for continuous power or fuel supply, allowing the drone to fly indefinitely by using various power sources such as electric, internal combustion, jet, gas rocket, or pressurized fluid engines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a drone with a mounted power source is used for firefighting, then the drone can be flown to high-rise floors, but the flight time is limited due to power source capacity
Solution Approach 1:
A wired cable is introduced as an intermediary to supply power from a ground-based power supply unit to the drone during flight. This allows the drone to operate indefinitely without being constrained by onboard power source capacity, resolving the contradiction between extended flight time and limited power storage.
2Duration of action of moving object
If the drone carries a larger power source to extend flight time, then continuous firefighting is possible, but the drone weight increases
Solution Approach 1:
The wired cable serves as a power transmission intermediary, allowing the drone to receive continuous power from a ground-based supply unit. This eliminates the need to increase onboard power source capacity, thereby avoiding additional drone weight while achieving unlimited flight time.
Solution Approach 2:
The power supply system transitions from a three-dimensional onboard battery to a two-dimensional wired connection with ground-based power supply. This dimensional shift allows unlimited power supply without increasing drone weight, as the power source is relocated to the ground infrastructure.
3Duration of action of moving object
If the drone is equipped with sufficient power for complete fire extinguishment, then sufficient firefighting capability is achieved, but the device complexity increases
Solution Approach 1:
The wired cable and ground-based power supply unit serve as simple intermediaries that provide continuous power without requiring complex onboard energy management systems. This external power supply approach achieves unlimited firefighting duration while maintaining relatively simple system architecture compared to integrating large-capacity power sources into the drone.
