Solution Overview

Problem

Existing sanitary fittings provide limited and inadequate feedback to users regarding the position and status of actuators and processing devices, making it difficult to manage the complex states and types of treated liquids effectively.

Innovation Solution

A sanitary fitting with a first control element for setting the quantity of liquid, a second control element for setting the type of liquid, and a display device with multiple optical elements connected to the control device to provide clear and flexible feedback on actuator settings and device states through separate activation of optical display elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a rotary selector switch is used to adjust hot water flow rate, then the hot water function can be activated and flow rate adjusted, but the operation becomes complex requiring multiple turning directions

Engineering Contradiction:
Improvehot water function activationVSAvoidactuator operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The actuating element is divided into two independent parts: a first actuating element for selecting water type (cold/warm/hot) and a second actuating element for adjusting flow rate. This segmentation allows each element to have a simple, dedicated function rather than combining multiple functions in one complex switch.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of using a single rotary switch that requires turning in different directions to activate function and adjust parameter, the patent inverts the approach by using two separate elements where each has a straightforward, intuitive operation mode.

Inventive Principle:
Principle #13The other way round (Inversion)

2Loss of information

If individual visual signals or colors are used for feedback, then the system can indicate treatment types, but the feedback is limited and inadequate for the multitude of liquid treatment methods

Engineering Contradiction:
Improvefeedback informationVSAvoidliquid treatment methods
Core Design Contradiction:
Loss of informationVSAdaptability or versatility

Solution Approach 1:

The display device transitions from one-dimensional individual color signals to a two-dimensional matrix arrangement of optical elements. This dimensional expansion allows multiple parameters (treatment type, quantity, temperature, flow rate) to be displayed simultaneously using combinations of illuminated elements rather than requiring separate signals for each parameter.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The matrix of optical elements serves multiple functions: indicating treatment type, displaying quantity settings, showing temperature levels, and providing operational status feedback. A single display structure replaces what would otherwise require multiple separate indicator systems.

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

3Loss of information

If a display device with multiple optical elements is implemented, then comprehensive feedback on actuator settings and device states is provided, but the device complexity increases

Engineering Contradiction:
Improvestatus feedbackVSAvoiddisplay device structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The control device receives signals from multiple sources (first actuating element, second actuating element, and processing device) and controls the entire matrix display from a single unit. This centralized control approach manages the complexity of coordinating multiple optical elements without requiring separate control circuits for each element or group of elements.

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

AI summary

The invention relates to a sanitary fitting for dispensing treated liquids, comprising a first actuating element for setting a quantity of a liquid to be dispensed, a second actuating element for setting the type of liquid to be dispensed, a display device having a plurality of optical display elements, and a control device which is connected on the one hand to the actuating elements and/or to a treatment device, and on the other hand to the display device, such that actuating element settings and/or at least a state of the treatment device are displayed by means of separate control of the optical display elements.
