Solution Overview

Problem

Existing functional units for sanitary facilities, combining mixers and distributors, require a large installation space due to their design and arrangement, making them not optimally compact for flush-mounting applications.

Innovation Solution

A compact functional unit design featuring cartridges with axial and/or radial inlets and outlets, connected via a connecting channel, incorporating electronic control and electromotive actuators, with axially rotatable sleeves and gear-driven stepper motors for efficient space utilization, allowing for a compact and space-saving solution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If conventional functional units with separate mixer and distributor components are used, then the functional unit can perform mixing and distribution functions, but the installation space required is large

Engineering Contradiction:
Improveinstallation spaceVSAvoidcomponent arrangement
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent combines the mixer and distributor into a single integrated cartridge assembly where both functional units share common components including the actuator, valve body, and mounting structure. This merging eliminates the need for separate mixer and distributor units, significantly reducing the installation space while maintaining both mixing and distribution functions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The distributor is nested within the mixer cartridge structure, with the distributor cartridge positioned inside or adjacent to the mixer cartridge. The actuator and control mechanisms are nested within the valve body, creating a compact hierarchical arrangement that minimizes the overall volume required for installation.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of manufacture

If multiple valves and control elements are housed in separate compartments, then each component can be optimized independently, but the overall device size increases

Engineering Contradiction:
Improvecomponent optimizationVSAvoiddevice size
Core Design Contradiction:
Ease of manufactureVSVolume of stationary object

Solution Approach 1:

The actuator serves multiple functions: it controls both the mixer valve and distributor valves, integrates the control mechanism, and provides the driving force for all valve operations. The electronic control unit performs multiple control tasks including temperature regulation, flow control, and coordination of multiple valves, eliminating the need for separate control compartments.

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