An aerial spray rainmaking device comprising a container, water storage assembly, pump, and spraying assembly, which includes a pressure tank and nozzles to nebulize and spray water into high-altitude clouds, utilizing a temperature regulator to maintain optimal water temperature for condensation and increase contact area with clouds, allowing for precise control and reduced catalyst usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If catalyst (sodium chloride and silver iodide) is delivered into the atmosphere via canon or fireworks to change cloud property, then rain can be generated, but the scope of area is small and the raining area cannot be precisely controlled

Engineering Contradiction:
Improvecatalyst usageVSAvoidraining area control precision
Core Design Contradiction:
Quantity of substanceVSMeasurement precision

Solution Approach 1:

The invention extracts and eliminates the catalyst component from the rainmaking system, replacing it with a physical process using heated water spray. This removes the limitation of small coverage area and imprecise control associated with catalyst delivery methods

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the physical parameter of water by heating it to high temperature before spraying into clouds. This parameter change (temperature) enables the water to effectively induce condensation in clouds, achieving rainmaking without catalyst and with controllable spray patterns for precise area coverage

Inventive Principle:
Principle #35Parameter changes

2Reliability

If catalyst is purchased and used for the generation of rain, then rainmaking can be achieved, but additional cost is required

Engineering Contradiction:
Improverainmaking effectivenessVSAvoidcatalyst cost
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The invention extracts and removes the catalyst from the system, replacing it with a thermal energy-based approach using heated water. This eliminates the need to purchase and transport catalyst materials while maintaining rainmaking effectiveness through physical condensation induction

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses readily available water and thermal energy (from vehicle exhaust or dedicated heating) to perform rainmaking, making the system self-sufficient without requiring external catalyst supplies. The water itself serves as the active agent when heated to appropriate temperatures

Inventive Principle:
Principle #25Self-service

3Productivity

If water is sprayed into high-altitude clouds to condense into water droplets, then rainmaking efficiency is improved, but the water temperature needs to be maintained to prevent cooling down

Engineering Contradiction:
Improverainmaking efficiencyVSAvoidwater temperature maintenance
Core Design Contradiction:
ProductivityVSTemperature

Solution Approach 1:

The system pre-heats water to high temperature before spraying it into the clouds. This preliminary heating action ensures the water maintains sufficient thermal energy to induce condensation when contacted with cloud particles, improving rainmaking efficiency before the actual spraying occurs

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention uses the hot water spray as an intermediary medium that transfers thermal energy to cloud particles, inducing condensation. The heated water acts as a thermal mediator between the heat source and the cloud system, facilitating rain formation without requiring direct thermal contact

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An aerial spray rainmaking device includes a container (10), a water storage assembly (20), a pump (30) and a spraying assembly (40). The water storage assembly (20) is disposed in the container (10) and includes a water tank (21) filled with water (B). The spraying assembly (40) includes a pressure tank (41) and multiple nozzles (42) communicating with the pressure tank (41). Two ends of the pump (30) separately communicate with the water tank (21) and the pressure tank (41). The water (B) is pressured by the pressure tank (41), and is nebulized and sprayed out of the container (10) by each nozzle (42). Therefore, widespread clouds in the high sky may be quickly condensed into water droplets to accomplish the function of rainmaking.
