Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water control valves lack temperature sensing and limiting functions, leading to unstable water temperature due to pressure drops and require separate upper bases for different valve bodies, increasing manufacturing costs.
Innovation Solution
A water control valve design featuring a valve shell, base, shunt valve, and temperature control unit with a cap, supporting sleeve, temperature sensor, sealing sleeve, and spring, allowing firm water channel formation and universal installation across various valve bodies through a joining technique, preventing pressure drops and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the shunt valve is installed between the upper base and the lower base without firm connection, then the installation is simple, but the water channels are not positioned stably causing unstable water outlet temperature due to large pressure drop
Solution Approach 1:
The valve base is divided into an upper base and a lower base that can be assembled separately, with the shunt valve installed in the upper base. This segmentation allows for simpler installation while maintaining stable water channels through the firm connection design between the upper base and shunt valve.
Solution Approach 2:
The upper base and shunt valve are firmly connected through joining techniques to form an integrated assembly. This merging ensures stable positioning of water channels and eliminates large pressure drops, thereby stabilizing the water outlet temperature while maintaining installation simplicity through modular design.
2Adaptability or versatility
If separate upper bases are made for different valve bodies, then each valve body has a dedicated upper base, but the manufacturing cost increases
Solution Approach 1:
The upper base is designed with a universal structure that can be applied to different valve bodies. The standardized interface and configuration allow the same upper base to accommodate various valve types, eliminating the need for separate upper bases for each valve body and thereby reducing manufacturing costs while maintaining adaptability.
3Device complexity
If the shunt valve is not firmly connected to the upper base, then the assembly process is simpler, but the water channels are not positioned stably causing large pressure drop
Solution Approach 1:
The joining technique is designed to be applied during the assembly process to firmly connect the shunt valve to the upper base. This preliminary action ensures stable positioning of water channels and minimizes pressure drop before the valve is put into service, while keeping the assembly process relatively simple through standardized joining procedures.

AI summary
A water control valve may include a valve shell, a valve base, a shunt valve, and a temperature control unit. The valve shell has a control base, a driving valve piece, and a fixed valve piece, and a valve stem upwardly protrudes from a center of the control base out of the valve shell. The valve base comprises an upper base and a lower base, which are configured to fit together, and the upper base has an inner space to accommodate and install the temperature control unit therein. The temperature control unit has a cap, a supporting sleeve, a temperature sensor, a sealing sleeve, and a spring.
