Sanitary Valve Unit With Hidden Flushing to Prevent Water Stagnation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary fittings with valve units often lead to hygienic issues due to stagnation of water, requiring frequent manual operation to maintain drinking water hygiene, which is inefficient and labor-intensive.
Innovation Solution
A valve unit with a second run for rinsing, allowing for periodic flushing with fresh water without visible flow, and a self-medium-operated servomagnet valve or manually operated valve design for efficient water management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If water is drawn off via the outlet valve designed as a fitting outlet, then the design is more compact, but a large amount of fluid stagnates in the sanitary fitting for extended periods
Solution Approach 1:
The outlet valve is divided into two separate outlets: a first outlet (4) for drawing off water and a second outlet (5) for flushing the valve unit. This segmentation allows the compact design to be maintained while adding a dedicated flushing function to prevent stagnation and ensure hygiene.
2Reliability
If the sanitary fitting is operated manually at certain intervals to flush water, then drinking water hygiene is maintained, but a large amount of work is required and the washbasin surface needs cleaning
Solution Approach 1:
The valve unit is equipped with a self-flushing capability through the second outlet (5) that can be activated by a control element. This allows the system to flush itself automatically without requiring manual operation, thereby maintaining drinking water hygiene while minimizing user effort and avoiding the need to clean the washbasin surface.
3Reliability
If a second outlet is added for flushing, then hygiene is maintained without manual operation, but the device complexity increases
Solution Approach 1:
The inlet (3) of the outlet valve is connected to both the first outlet (4) and the second outlet (5) through a common valve housing (6). This merging of functions within a single integrated valve unit allows the flushing capability to be added without proportionally increasing overall device complexity, as both outlets share common structural elements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The valve unit can be operated with minimal effort even during longer periods of non-activity, maintaining hygiene by preventing stagnation and allowing for efficient rinsing without manual intervention.
Implementation Method 1
an actuating unit with a servomagnet valve or with a magnet valve
