Universal Atomizer Segmented Paint Feeds for Solvent and Water Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizers used in paint shops face challenges when switching between solvent-based and water-based paint systems, leading to increased rinsing effort, chemical reactions, and potential damage due to incompatibility, making the process unsuitable for series production.
Innovation Solution
The atomizer features separate paint feeds with independent main needle valves and return lines for each paint system, along with dedicated rinsing lines and flushing agents to prevent chemical reactions and facilitate efficient rinsing, allowing for safe operation with both solvent-based and water-based paints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single paint supply is used for both solvent-based and water-based paints, then the atomizer structure is simplified, but chemical reactions occur between incompatible paint systems causing hardening and damage
Solution Approach 1:
The patent divides the paint supply system into separate, independent feeds for solvent-based paints and water-based paints. Each paint system has its own dedicated supply line, preventing direct contact between incompatible paint systems and eliminating the risk of chemical reactions and hardening damage.
2Reliability
If separate paint feeds are provided for different paint systems, then chemical reactions are prevented, but the device complexity increases
Solution Approach 1:
The patent employs a universal atomizer design that can handle multiple paint systems through separate feeds. The common application elements (spray nozzle, atomization chamber) serve both solvent-based and water-based paints, reducing overall complexity despite having separate supply lines. This multi-functional approach allows one atomizer to replace what would traditionally require multiple specialized devices.
3Reliability
If complex rinsing processes are used when changing paint systems, then chemical reactions are prevented, but production downtime increases
Solution Approach 1:
The rinsing system is segmented into separate rinsing lines for each paint system, with dedicated rinsing agents. This allows independent, rapid rinsing of each feed line without requiring complex multi-step processes, significantly reducing changeover time while ensuring complete separation of paint systems.
Solution Approach 2:
The patent introduces separate rinsing lines with appropriate rinsing agents as intermediaries between paint system changes. These dedicated rinsing pathways enable quick transition by flushing out residual paint from one system before introducing the next, preventing contamination without requiring prolonged manual cleaning or complex multi-agent rinsing sequences.
4Reliability
If mechanical cleaning is performed after chemical reactions, then atomizer damage is addressed, but series production becomes unsuitable due to production downtime
Solution Approach 1:
The patent implements preliminary protective measures by completely preventing chemical reactions through separate paint feeds before they can cause damage. This proactive approach eliminates the need for subsequent mechanical cleaning and repairs, ensuring continuous operation and maintaining series production capability.

AI summary
The invention relates to an atomizer (1), particularly a rotary atomizer, comprising a first paint inlet (3) for a first paint system, e.g. a solvent-based paint. The atomizer (1) according to the invention further comprises an additional second paint inlet (4) for a second paint system, e.g. a water-based paint. The two paint inlets (3, 4) are separated from one another such that the atomizer (1; 28) can alternatively apply one of the two different paint systems. The invention also relates to a corresponding operating method.
