Solution Overview
Problem
Conventional spray mixers require complex connections and manual mixing of components, leading to hazardous material exposure, waste generation, and inefficient VOC management during coating applications.
Innovation Solution
A connecting device with a single or two-piece plastic design, featuring an inlet and outlet section with connectors and passages, used to securely attach a spray nozzle to a hose, allowing for direct gas supply and efficient mixing of multi-component paints without pre-mixing, reducing hazardous exposure and waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional spray mixers use complex connections with multiple components, then the connection reliability is improved, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent combines multiple separate connection components (hose connector, elbow, spray nozzle connector, and mixing chamber) into a single integrated plastic body. This merging eliminates the need for multiple separate parts while maintaining the functional reliability of the connection system, directly resolving the contradiction between connection reliability and device complexity.
Solution Approach 2:
The single piece connecting device performs multiple functions simultaneously: it connects hoses and spray nozzles, provides mixing chambers for coating components, directs gas flow, and ensures proper alignment. This multi-functionality reduces the overall system complexity while maintaining reliable connections, addressing the contradiction between reliability and complexity.
2Device complexity
If manual mixing of components is required, then the device complexity is reduced, but hazardous material exposure increases and manufacturing precision deteriorates
Solution Approach 1:
The connecting device incorporates self-contained mixing chambers that automatically mix coating components as they flow through the device. This self-service mixing eliminates the need for manual mixing operations, reducing hazardous material exposure to operators while maintaining simple device architecture, thus resolving the contradiction between device complexity and harmful factors.
3Manufacturing precision
If pre-mixing of multi-component paints is required, then the manufacturing precision is improved, but the loss of time increases and productivity deteriorates
Solution Approach 1:
The device incorporates pre-configured mixing chambers with optimized geometry and flow paths that ensure proper mixing of multi-component paints immediately upon injection. This preliminary mixing action eliminates the need for separate pre-mixing steps, maintaining manufacturing precision while significantly reducing preparation time and increasing overall productivity.
Solution Approach 2:
The connecting device enables continuous mixing and application of multi-component paints without interruption or batch preparation. The integrated design allows components to flow continuously through the mixing chambers and onto the substrate, eliminating downtime associated with manual pre-mixing and maintaining both precision and high productivity throughout the application process.
