Solution Overview
Problem
Existing free-standing faucet designs face difficulties in accurately and securely assembling the mixing valve with the pipe joint, leading to complications in water flow and assembly issues due to size and structural limitations.
Innovation Solution
The design incorporates a mixing valve chamber with a horizontally positioned pipe joint and an adapter featuring aligned channels and contact surfaces, along with positioning pins and sealing gaskets, to ensure easy, secure, and accurate connection between the mixing valve and pipe joint, facilitating smooth water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a mixing valve is assembled with a pipe joint using conventional methods, then the assembly can be completed, but the assembly process is complicated and the connection is not firm due to size and structural limitations
Solution Approach 1:
An adapter is introduced as an intermediary component between the mixing valve and the pipe joint. The adapter includes a first end that connects to the pipe joint and a second end that connects to the mixing valve, with water channels formed between these ends. This intermediary structure simplifies the assembly process and ensures firm connection by bridging the interface between components with different specifications.
Solution Approach 2:
The connection system is divided into separate functional segments: the pipe joint, the adapter, and the mixing valve. The adapter itself is segmented into a first end for pipe joint connection and a second end for mixing valve connection. This segmentation allows each component to be optimized independently and assembled in a straightforward sequence.
2Manufacturing precision
If positioning components are added to the mixing valve for accurate alignment, then the connection accuracy improves, but the structure becomes complicated and assembly becomes difficult
Solution Approach 1:
Positioning structures such as positioning ribs and positioning grooves are designed with asymmetric geometries that provide precise alignment between the adapter and the mixing valve. The positioning rib on the adapter fits into a corresponding positioning groove, creating a unique orientation that ensures accurate connection without requiring complex positioning mechanisms.
Solution Approach 2:
The positioning structures are designed to automatically align the components during assembly. The positioning rib and groove configuration enables the mixing valve to self-align with the adapter when brought together, eliminating the need for external alignment tools or complex adjustment mechanisms.
3Device complexity
If the mixing valve is directly connected to the pipe joint, then the structure is simple, but the water flow connection is not smooth due to misalignment of inlet/outlet ports
Solution Approach 1:
The adapter serves as a mediator that ensures proper alignment between the water channels of the pipe joint and the mixing valve. Water channels are formed within the adapter body, creating a continuous flow path from the pipe joint through the adapter to the mixing valve, thereby ensuring smooth water flow connection.
Solution Approach 2:
The adapter performs multiple functions: it connects the pipe joint to the mixing valve, provides water channel pathways for smooth flow, incorporates positioning structures for accurate alignment, and includes sealing surfaces for leak prevention. This multi-functionality resolves the contradiction by maintaining relative structural simplicity while achieving reliable water flow connection.

AI summary
A free-standing faucet which includes a valve assembly, a spout, an inlet tube set, and a free-standing casing tube, a spray holder, and a spray is revealed. The valve assembly consists of a housing, a mixing valve, and a diverter, and a handle. The housing is composed of a mixing valve chamber in which the mixing valve is mounted, a pipe joint connected to the inlet tube set, a connection portion formed on one side of the pipe joint close to the mixing valve chamber, a first cold water channel, and a first hot water channel. The first hot and cold water channels are formed inside the pipe joint and communicating with the connection portion and the inlet tube set. An adapter is connected to the connection portion and having second cold and hot water channels. Thereby the mixing valve can be assembled and positioned easily, securely and accurately.
