Engineering Contradiction Analysis
1Reliability
If manned aircraft are used for cloud seeding, then seeding operations can be conducted, but operational costs increase and safety risks increase
Solution Approach 1:
The patent uses unmanned aerial vehicles (UAVs) as copies or substitutes for manned aircraft to perform cloud seeding operations. The UAVs are equipped with sensors and machine learning systems that replicate the decision-making capabilities of human pilots, enabling automated cloud identification and seeding material dispersal without requiring human operators in the aircraft.
Solution Approach 2:
The patent replaces the mechanical system of manned aircraft operation with an automated system comprising UAVs, sensor suites, and machine learning algorithms. The machine learning model processes real-time weather data and autonomously determines optimal seeding locations and timing, substituting human cognitive functions with computational algorithms.
2Manufacturing precision
If traditional weather modification programs are used, then cloud seeding can be performed, but data collection accuracy is insufficient and targeting precision is poor
Solution Approach 1:
The patent implements a feedback loop where sensor suites on UAVs continuously collect real-time weather and cloud system data, which is then processed by machine learning models to determine optimal seeding locations. The system uses this feedback to dynamically adjust seeding strategies and improve targeting precision throughout the operation.
Solution Approach 2:
The patent transforms traditional weather modification by changing the parameters of data collection and processing. Instead of relying on conventional weather stations and manual analysis, the system uses multiple sensors on UAVs to collect high-resolution spatial and temporal data, which is then processed through machine learning algorithms to extract meaningful patterns and make precise seeding decisions.
3Measurement precision
If ground-based seeding systems are used, then seeding operations can be conducted, but the ability to accurately deliver seeding materials to appropriate clouds is limited
Solution Approach 1:
The patent transitions from ground-based two-dimensional seeding operations to three-dimensional aerial operations using UAVs. This dimensional change enables the system to access and seed clouds at various altitudes and horizontal positions, significantly improving targeting accuracy and delivery capability compared to ground-based systems that are constrained to surface level operations.
Data Source
AI summary
Data including current locations of candidate clouds to be seeded is obtained; based on same, a vehicle is caused to move proximate at least one of the candidate clouds to be seeded. Weather and cloud system data are obtained from a sensor suite associated with the vehicle, while the vehicle and sensor suite are proximate the at least one of the candidate clouds to be seeded. Vehicle position parameters are obtained from the sensor suite associated with the vehicle. Based on the weather and cloud system data and the vehicle position parameters, it is determined, via a machine learning process, which of the candidate clouds should be seeded, and, within those of the candidate clouds which should be seeded, where to disperse an appropriate seeding material. The vehicle is controlled to carry out the seeding on the candidate clouds to be seeded, in accordance with the determining step.
