Solution Overview
Problem
Current spraying technologies in the wine-making industry face challenges in precisely controlling and varying spraying parameters such as flow rate and air speed, leading to inefficiencies, excessive energy consumption, and environmental impact, due to factors like nozzle wear, centralized air generation, and lack of control over droplet size and distribution.
Innovation Solution
A compact spraying module that uses a rotary atomizer driven by a common electric motor, combined with a fan system, to generate a controlled stream of carrier air and liquid droplets, allowing for adjustable flow rates and reduced energy consumption, with an electronic control unit for remote module control and precise parameter adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If centralized air generation and distribution is used, then air supply to multiple nozzles is simplified, but energy consumption increases and air speed control precision deteriorates
Solution Approach 1:
The patent divides the air supply system into independent modular units, with each spraying module having its own air pump and air stream generation system. This segmentation eliminates the need for long centralized air distribution piping, reducing energy losses and allowing independent control of air speed at each nozzle without requiring high-power centralized turbines.
2Adaptability or versatility
If nozzle flow rate is adjusted by changing jet geometry, then flow rate variation is achieved, but manufacturing complexity increases and jet wear affects precision
Solution Approach 1:
The patent replaces static jet geometry adjustment with dynamic control of operating parameters. The flow rate is adjusted by varying the liquid pump delivery settings and air pump speed, rather than physically changing jet dimensions. This dynamic approach maintains simple nozzle geometry while achieving flexible flow rate control through electronic parameter adjustment.
3Speed
If high pressure is used to increase droplet speed, then droplet projection distance improves, but droplet size decreases and evaporation increases
Solution Approach 1:
The patent optimizes the balance between pressure, droplet size, and speed by independently controlling liquid flow rate and air stream velocity. Rather than relying solely on high pressure, the system adjusts the ratio of liquid to air parameters to achieve appropriate droplet sizes and velocities, reducing evaporation while maintaining effective projection distance.
4Adaptability or versatility
If manual nozzle changing is performed to adjust flow rate, then flow rate control is achieved, but operation time increases and safety risks arise
Solution Approach 1:
The patent replaces manual mechanical nozzle changing with electronic control systems. Flow rate adjustment is achieved through electronic control of liquid and air pumps, allowing parameter modification without physical intervention. This substitution eliminates the time-consuming and safety-risky process of manual nozzle replacement while maintaining full flow rate control capability.
5Quantity of substance
If small jets are used to reduce pulp dilution, then active material concentration is preserved, but nozzle clogging risk increases
Solution Approach 1:
The patent maintains small jet dimensions for concentrated active material delivery but compensates for clogging risk through dynamic parameter adjustment. The system monitors and adjusts liquid flow rate and air stream velocity to prevent conditions that would cause clogging, while preserving the concentration benefits of small jets through optimized operational parameters rather than larger physical dimensions.
