Solution Overview

Problem

Existing control arrangements for water fittings with multiple actuators, such as valves and mixing units, are complex and time-consuming due to nested logical operating levels, requiring multiple operating actions for parameter input.

Innovation Solution

The control arrangement features separate, spatially distinct input screens for each logical operating level, allowing operators to access and input parameters for different levels without nested structures, with all input screens designed identically for hardware consistency and easy installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If nested logical operating levels are used to organize multiple functions, then the control arrangement can manage complex water fitting operations, but the operation becomes confusing and time-consuming requiring multiple operating actions

Engineering Contradiction:
Improvenumber of functionsVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The control arrangement is divided into multiple independent operating units, each with its own input screen for accessing specific logical operating levels. This segmentation allows operators to directly access different functions (water outlet selection, automatic functions, etc.) without navigating through nested hierarchical levels, reducing operational complexity while maintaining comprehensive functionality

Inventive Principle:
Principle #1Segmentation

2Device complexity

If a single input screen is used for multiple logical operating levels, then the control arrangement remains compact, but parameter input becomes confusing and requires multiple operating actions

Engineering Contradiction:
Improvecontrol structureVSAvoidparameter input time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

Instead of using one input screen for multiple logical operating levels, the system provides separate input screens for each logical operating level. This allows operators to directly access the desired function without sequential navigation, significantly reducing the time required for parameter input while the modular architecture keeps overall device complexity manageable

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a hierarchical single-dimension access structure to a parallel multi-dimension structure where multiple input screens are spatially distributed. This dimensional change allows simultaneous access to different logical operating levels, eliminating the need for nested navigation and reducing operational time

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

3Ease of operation

If separate operating units with individual input screens are provided for different logical operating levels, then parameter input is simplified and faster, but the device requires more components

Engineering Contradiction:
Improveparameter input simplicityVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Multiple operating units are designed with identical hardware configurations, allowing each unit to serve multiple functions. This universality means that while there are more components, each component is standardized and multi-functional, reducing the overall system complexity through repetition of proven designs rather than requiring unique complex components for each function

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