Sanitary Faucet Mixing Valve Layout for Compact Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary faucets require a large installation space due to the design of the mixing valve and control element, which limits their compactness.
Innovation Solution
A sanitary faucet design featuring a mixing valve with a control disk rotated about a first axis and a first control element rotated about a second axis that does not parallel to the first, utilizing a non-parallel axis configuration for the control elements and transmissions like bevel-gear pairs or epicyclic gear units to achieve compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional mixing valve and control element design is used, then the temperature and flow control functionality is achieved, but the installation space required is large
Solution Approach 1:
The control element is designed to rotate about a second axis that is non-parallel to the first axis of rotation of the control disk. This dimensional change in the control mechanism allows for compact arrangement of components, reducing the overall installation space while maintaining full control functionality for both temperature and flow rate
2Device complexity
If the control element rotates about an axis parallel to the control disk axis, then the control mechanism is simple, but the device occupies more space
Solution Approach 1:
By changing the axis of rotation of the control element to be non-parallel to the control disk axis, the patent achieves compact component arrangement. The transmission mechanism (such as bevel gears or epicyclic gears) efficiently transfers motion between non-parallel axes, maintaining operational simplicity while dramatically reducing the space required for the control mechanism
