Thermostatic Shower Valve Layout for Reversible Control Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower sets do not allow users to interchange the positions of the thermostatic valve element and the switching valve element according to user preference, as rotating the shower to change their positions disrupts the hot and cold water inlets, thereby affecting the thermostatic valve's ability to maintain constant temperature.
Innovation Solution
A shower set design that includes a thermostatic valve element, a switching valve element, a main body with valve seats, and gland caps, allowing the positions of the valve elements to be interchanged by rotating the main body 180 degrees, with specific water inlet and outlet configurations to maintain proper water flow and temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shower is rotated 180 degrees to interchange the positions of the thermostatic valve element and the switching valve element, then the user can adjust the position according to using habit, but the hot water inlet and cold water inlet positions are disrupted, causing the thermostatic valve element to fail in outputting water of constant temperature
Solution Approach 1:
The patent divides the valve assembly into separate components: the thermostatic valve element, the switching valve element, and the valve body with independently configurable inlet ports. This segmentation allows each component to be optimized independently and reconfigured without affecting the others, enabling position interchangeability while maintaining proper hot and cold water connections.
Solution Approach 2:
The patent makes the inlet port configuration dynamic by providing the valve body with multiple inlet ports that can be selectively connected to hot water and cold water supplies. This dynamic configuration allows the system to adapt to different installation orientations and user preferences while ensuring the thermostatic valve element always receives hot and cold water from the correct sources.
2Ease of manufacture
If the positions of the thermostatic valve element and switching valve element are fixed during manufacturing, then the manufacturing process is simplified, but the user cannot interchange their positions according to personal preference
Solution Approach 1:
The valve body is designed with universal inlet port configurations that can accommodate different hot and cold water connection arrangements. This multi-functionality allows the same valve body design to be used in various installation scenarios and orientations, providing position flexibility without requiring different manufacturing processes for each configuration.
Solution Approach 2:
The patent incorporates preliminary configuration options during manufacturing by providing pre-defined inlet port arrangements in the valve body that can be selected based on the intended installation orientation. This allows the manufacturer to prepare the valve body for different configurations in advance, maintaining manufacturing simplicity while enabling end-user flexibility in final positioning.

AI summary
A shower set comprises a thermostatic valve element(1), a switching valve element (2), a main body (3), a first valve seat (4) and a second valve seat (5). The main body (3) is provided with a first water inlet (313) and a second water inlet (314) capable of interchangeably connecting a hot water inlet pipe and a cold water inlet pipe. When hot water is introduced into the first water inlet (313), the first valve element (4) is inserted into an accommodation cavity of the valve seat for the thermostatic valve (1) to place, a first hole (45) of the first valve seat is communicated with the first water inlet (313) and a thermostatic hot water inlet (14) and a second hole (46) is communicated with the second water inlet (314) and a cold water inlet (15). When cold water is introduced into the first water inlet (313), the second valve seat (5) is inserted into the accommodation cavity of the valve seat for the thermostatic valve element(1) to place, a fourth hole (59) of the second valve seat is communicated with the first water inlet (313) and the hot water inlet (14), and a third hole (58) is communicated with the second water inlet (314) and the cold water inlet (15). Mixed water flowing to the switching valve element (2) at the other end of the main body (3) is conveyed to a water outlet of the main body (3). The shower set provided by the application can interchange positions of the switching valve element (2) and the thermostatic valve (1) by rotating the main body (3).
