Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing static spray mixers for mixing and spraying two free-flowing components are complex and expensive, making them less economical for single-use applications, and are difficult to use in areas with limited access.
Innovation Solution
A combination of a static spray mixer with an intermediate piece that includes a tubular mixer housing and an atomization sleeve, featuring a deflection angle between the inlet and outlet areas, allowing for easy connection without threads and enabling flexible atomization, especially for hard-to-reach areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex multi-component structure with threads and multiple parts is used, then the device can achieve functional requirements, but the device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent combines the mixer housing and atomizing nozzle into a single integrated component. The mixer housing includes integrated flow channels that directly connect to the atomizing nozzle, eliminating the need for separate connection parts, threads, and multiple assembly steps. This merging reduces structural complexity while maintaining the functional performance of mixing and atomizing operations.
2Device complexity
If the spray mixer is designed for single use with simple structure, then the device complexity is reduced, but the handling and adaptability to different applications are limited
Solution Approach 1:
The patent introduces a deflectable connection section between the mixer housing and atomizing nozzle that can be adjusted to different angles. This dynamic element allows the spray direction to be changed without modifying the basic simple structure, enabling the single-use mixer to adapt to various application scenarios including hard-to-reach areas while maintaining structural simplicity.
3Device complexity
If the spray mixer has a fixed straight configuration, then the structure is simple, but it cannot access hard-to-reach areas effectively
Solution Approach 1:
The connection section between the mixer housing and atomizing nozzle is designed to be deflectable at an angle, allowing the spray direction to be oriented towards hard-to-reach areas. This dynamic configuration enables the simple structure to adapt to various access requirements without increasing overall structural complexity.
Solution Approach 2:
The patent adds angular deflection capability to the linear spray path by introducing a deflectable connection section. This dimensional change from a straight-line configuration to an angular configuration enables access to hard-to-reach areas while maintaining the simplicity of the basic mixer structure.

Function Achieved in This Case
This configuration simplifies handling and expands the application range of static spray mixers, ensuring homogeneous atomization and stable fluid flow, even in difficult-to-access areas, while maintaining the same flow conditions as the original mixer housing.
Implementation Method 1
the atomization sleeve having an inlet channel for a pressurized atomizing medium and an inner surface with a plurality of separate grooves, which together with the mixer housing can form separate flow channels
Implementation Method 2
atomizes the material emerging from the mixing element

AI summary
The intermediate piece (1) has inlet area (11) for cooperating with distal end portion (27) of mixer housing (2), and outlet (12) for cooperating with atomizing case (4). The inlet region and the outlet are provided at non-zero diversion angle. The outlet and inlet area are provided away from an end portion of housing. The outer contour of outlet is set equal that of mixer housing, so that end portion (13) of outlet is made to cooperate with case during interaction of distal end of housing with case. An independent claim is included for combination of static spray mixer for mixing and spraying of two flowable components with intermediate piece.
