Solution Overview

Problem

Existing static mixers for mixing and spraying flowable components are complex and costly, with intricate structures that complicate installation and are not cost-effective for single-use applications, particularly when used for high-viscosity materials like sealing compounds or two-component adhesives.

Innovation Solution

A simplified static spray mixer design featuring a tubular one-piece mixer housing with a mixing element and an atomization sleeve, where the atomization sleeve is connected thread-free, and grooves on the mixer housing or sleeve allow for efficient atomization using a pressurized medium, reducing complexity and manufacturing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complex multi-component structure with threaded connections and retaining nuts is used, then reliable atomization and mixing can be achieved, but device complexity and manufacturing cost increase significantly

Engineering Contradiction:
Improveatomization reliabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate components (mixer housing, atomizer, retaining nut, cap) into a single integrated mixer housing with integrated atomization features. The atomization channels are formed directly within the mixer housing structure, eliminating the need for separate atomizer components and their associated fastening mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mixer housing serves multiple functions simultaneously: it contains the mixing elements, provides structural support, and incorporates integrated atomization channels. This multi-functional design replaces what previously required separate specialized components for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If multiple separate components with threaded connections are used, then functional reliability is maintained, but ease of manufacture and installation deteriorate

Engineering Contradiction:
Improvefunctional reliabilityVSAvoidmanufacturing simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent merges multiple manufactured components into a single molded housing structure, transforming a multi-step assembly process involving threading and fastening into a single manufacturing operation that produces an integrated component with built-in atomization channels.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If a simple one-piece mixer housing with integrated atomization channels is used, then device complexity and manufacturing cost are reduced, but the number of components and assembly steps must be minimized

Engineering Contradiction:
Improvestructure simplicityVSAvoidmanufacturing automation potential
Core Design Contradiction:
Device complexityVSEase of manufacture

Solution Approach 1:

The integration of atomization channels directly into the mixer housing creates a single-component design that can be manufactured as one piece, eliminating assembly steps and enabling fully automated manufacturing processes while maintaining functional reliability.

Inventive Principle:
Principle #5Merging (Combining)
