Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing program-controlled sanitary facilities have not gained widespread practical use due to a lack of truly practical portfolios that meet the increasing demand for comfort and ease of use.
Innovation Solution
A sanitary room with a programmable electronic control system that integrates separate user interfaces for lighting and sound programs, allowing manual modification and selection, and a device-user interface for water-delivery programs, with user identification and scenario-based control for enhanced user friendliness and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If program-controlled sanitary facilities are implemented, then comfort and functionality are improved, but device complexity increases
Solution Approach 1:
The control system is segmented into multiple independent user interfaces: a first user interface for lighting programs and a second user interface for water-delivery programs. This segmentation allows each interface to handle specific functions, reducing the complexity perceived by the user while maintaining comprehensive program control capabilities.
Solution Approach 2:
The electronic control system serves multiple functions through a unified program memory that stores both lighting programs and water-delivery programs. The system can execute different types of programs (lighting, water delivery, sound) through a common control architecture, reducing overall system complexity while providing versatile functionality.
2Ease of operation
If multiple user interfaces are provided for different functions, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The user interfaces are segmented by function: the first user interface is dedicated to lighting program selection and modification, while the second user interface handles water-delivery program selection and modification. This functional segmentation makes each interface simpler and more intuitive to operate.
Solution Approach 2:
The electronic control system acts as an intermediary that receives commands from multiple specialized user interfaces and coordinates their execution through a unified program memory and data-processing unit, managing complexity internally while presenting simplicity to the user.
3Adaptability or versatility
If manual modification of programs is allowed, then adaptability is improved, but ease of operation worsens
Solution Approach 1:
Manual modification capabilities are provided locally at each user interface according to its specific function: the first user interface allows local modification of lighting programs, and the second user interface allows local modification of water-delivery programs. This localized adaptability maintains ease of operation by keeping modifications simple and context-specific.
Solution Approach 2:
The system dynamically adjusts between automatic program execution and manual modification modes. Users can switch between pre-programmed scenarios and custom adjustments as needed, allowing the system to adapt to different operational contexts while maintaining ease of use through intuitive controls.

AI summary
A sanitary room of a building has an access point for persons and a sanitary station, which has a sanitary apparatus having a metering and mixing valve unit, a lighting apparatus, and a sound apparatus. A programmable electronic controller influences the metering and mixing valve unit, the lighting apparatus, and the sound apparatus. The electronic controller has a memory for storing water discharge programs, a memory for storing lighting programs, a memory for storing sound programs, and a data-processing unit, which operates an actuator of the metering and mixing valve unit, an illuminant controller, and a sound generator. The sanitary station includes a device user interface associated with the sanitary apparatus which allows one of the water discharge programs to be selected and manually modified. Adjacent the access point, a room user interface is provided, which allows lighting programs and sound programs to be selected and manually modified.
