Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water faucets have a shortened lifespan due to damage to the external threads of the inlet pipes and difficulties in connecting and disconnecting the nozzle, which affects the durability and functionality.
Innovation Solution
A valve body design featuring copper casing pipes around each water inlet pipe, with external threads and a clip-on nozzle connecting assembly that includes a resilient snapping component and seal rings for secure and quick connections, preventing thread damage and enhancing longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the external thread of the water inlet pipe is exposed for connection, then the nozzle can be connected and disconnected, but the external thread is damaged during use which shortens the lifespan of the water faucet
Solution Approach 1:
The water inlet pipe is segmented into two parts: the internal thread portion integrated with the valve body and the external thread portion separated as a removable connector. This segmentation allows the external thread to be replaced if damaged, while the main valve body with internal thread remains intact, thus resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
A connector serves as an intermediary component between the valve body's internal thread and the nozzle's external thread. This mediator allows the nozzle to be connected and disconnected without directly exposing the valve body's thread to damage, thereby maintaining both operational ease and system reliability.
2Device complexity
If the external thread of the water inlet pipe is used for connection, then the structure is simple, but the external thread gets damaged which adversely affects the lifespan
Solution Approach 1:
The connection structure is segmented into a permanent internal thread integrated with the valve body and a removable external thread connector. This segmentation protects the main valve body structure from thread damage while maintaining overall structural simplicity, resolving the contradiction between device complexity and reliability.
Solution Approach 2:
The external thread connector is designed as a replaceable, lower-cost component that can be easily replaced if damaged, while the main valve body remains a durable, long-lasting component. This approach maintains structural simplicity while ensuring the overall system reliability through replaceable parts.
3Ease of operation
If the nozzle connecting end has external thread, then connection is possible, but it adversely affects the connection and disconnection of the nozzle
Solution Approach 1:
Instead of providing an external thread on the valve body's nozzle connecting end, the invention inverts the arrangement by providing an internal thread on the valve body and an external thread on the removable connector. This inversion protects the valve body structure while maintaining ease of nozzle connection and disconnection.

AI summary
Provided is a valve body of a water faucet including a water outlet pipe seat and two water valve seats configured to receive a cold water valve cartridge and a hot water valve cartridge respectively at two sides of the water outlet pipe seat. Each valve seat is formed with a water inlet pipe enclosed by a cooper casing pipe. Each valve seat is fixed to a corresponding copper casing pipe via injection molding. The valve body of a water faucet in accordance with the present invention is formed with a copper casing pipe which can be connected to an external water pipe around each water inlet pipe. Therefore, lifespan of the water faucet is prolonged remarkably.
