Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional aircraft are used for water bombing, then firefighting coverage area is improved, but pilot risk and operational safety deteriorate
Solution Approach 1:
The UAV performs firefighting operations autonomously without requiring a human pilot to be present in the aircraft. The system uses automated navigation, payload release control, and flight management to execute water bombing missions independently, thereby eliminating pilot risk while maintaining firefighting coverage capability
Solution Approach 2:
The patent replaces the human pilot-controlled mechanical system with an automated electronic control system. The UAV incorporates flight control computers, GPS navigation, and automated payload release mechanisms that substitute for human mechanical operations, enabling safe autonomous firefighting in hazardous environments
2Manufacturing precision
If aircraft fly at low altitude for water bombing, then delivery precision is improved, but turbulence and flight safety deteriorate
Solution Approach 1:
The UAV pre-calculates the optimal release point and release timing based on its current position, speed, and trajectory before reaching the target area. The system uses navigation data and payload characteristics to determine the precise moment for release, ensuring accurate delivery without needing to fly at dangerously low altitudes through turbulent zones
Solution Approach 2:
The system continuously monitors flight parameters, wind conditions, and payload status, using this feedback to adjust the release timing and trajectory. This closed-loop control enables precise payload delivery while maintaining safe flight altitude by making real-time corrections rather than requiring low-altitude manual piloting
3Productivity
If multiple aircraft are deployed for firefighting, then firefighting effectiveness is improved, but operational cost and resource requirement deteriorate
Solution Approach 1:
The UAV is designed as a multi-functional platform capable of performing various firefighting tasks including water bombing, retardant delivery, and aerial reconnaissance. This universal design allows a single aircraft type to replace multiple specialized aircraft, achieving comprehensive firefighting effectiveness while reducing the total number of aircraft required
Solution Approach 2:
The patent employs UAVs with adjustable payload capacities, flight altitudes, and speeds that can be optimized for different firefighting scenarios. By changing operational parameters rather than deploying multiple fixed-configuration aircraft, the system achieves versatile firefighting capability with a smaller, more cost-effective fleet

AI summary
A method of fire-fighting is provided based on unmanned aerial vehicles “UAV(s)” launched from transporter aircrafts to deliver water or fire-retardants or any other fire-fighting materials to a location selected by the fire-fighting personnel. A capability of putting-off high intensity forest fires is provided that stems from the precision and the quantity of material that can be delivered per unit surface per unit time. After releasing the fire-fighting material(s), the UAV reaches a safe altitude from which it flies on autopilot to intercept and then proceed on a pre-programmed route to land per pre-programmed instructions on an airfield from which fire-fighting transporter(s) operate, allowing a high efficiency along the line, from loading the transporter airplanes to maximizing the quantity of material that reach the target, to minimizing the remote-pilot time and up to the recovery system that minimizes the recovery cost and it maximizes UAVs' utilization by a quick turnaround.
