Compact Two-Way Valve Layout for Integrated Sanitary Fittings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary fittings with two-way valves have a high space requirement, making it difficult to integrate them into the fittings or requiring larger designs, which limits design freedom and increases material needs.
Innovation Solution
A sanitary fitting design that incorporates a two-way valve with a compact valve body arrangement, allowing the valve to be rotatably mounted between two valve seats within a dash housing, thereby reducing space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional two-way valves are used in sanitary fittings, then the valve function is achieved, but the installation space requirement increases
Solution Approach 1:
The patent combines the two-way valve with the jet former into a single integrated component. The valve body is formed as one piece with the jet former, eliminating the need for separate valve housing and reducing installation space. The valve seats are integrated into the valve body structure itself, further consolidating the design.
Solution Approach 2:
The valve body is designed with nested internal structures where the valve seats are positioned within the valve body cavity. The actuator mechanism is nested within the valve body, with the piston moving inside the cylindrical cavity. This nested arrangement minimizes the external dimensions while maintaining full valve functionality.
2Reliability
If conventional two-way valves are used in sanitary fittings, then the valve function is achieved, but the material requirements increase
Solution Approach 1:
The valve body and jet former are manufactured as a single integrated component, reducing the total material quantity needed. The integration eliminates the need for separate valve housing, mounting brackets, and connecting elements, thereby reducing overall material consumption while maintaining structural integrity and valve functionality.
3Reliability
If conventional two-way valves are used in sanitary fittings, then the valve function is achieved, but the design freedom is limited
Solution Approach 1:
The valve employs a rotatable valve body that can be positioned at different angles to control fluid flow direction. The actuator mechanism allows dynamic adjustment between different jet types by rotating the valve body to different positions, providing design flexibility for multiple jet patterns including rain jet, full jet, massage jet, and pearl jet configurations.
Solution Approach 2:
The integrated valve-jet former design serves multiple functions: it acts as a two-way valve for flow control, a jet generator for different spray patterns, and a mounting component for the actuator. This multi-functionality enhances design freedom by consolidating several components into one versatile element.
