Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pull-out faucets face issues with the limited load-bearing capability and precision requirements of the valve core seat in the corner portion between the faucet main body and side wall branch pipe, leading to potential leakage and increased manufacturing costs due to the snapping fit design.
Innovation Solution
A valve core seat assembly with a main body fixing seat and valve core seat, featuring a matching included angle and threaded connections, along with a positioning pin, to securely attach the valve core seat to the faucet main body without high precision processing of the side wall branch pipe, enhancing the connection's firmness and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If snapping fit structure is used between valve core seat and side wall branch pipe, then assembly is simplified, but load-bearing capability is limited and valve core seat may fall off
Solution Approach 1:
The patent combines the snapping fit structure with a threaded connection structure. The valve core seat assembly includes both a snapping portion that fits into the side wall branch pipe and a threaded portion that engages with a threaded hole in the main pipe, creating a hybrid connection that provides both ease of assembly and high load-bearing capability.
Solution Approach 2:
The connection structure uses composite fixing methods combining elastic deformation (snapping fit) with mechanical threading. The valve core seat assembly integrates different fixing mechanisms (snapping + threading) to achieve both simplicity and strength in the connection.
2Ease of manufacture
If snapping fit is used for valve core seat connection, then assembly is easier, but manufacturing precision requirements increase to prevent leakage
Solution Approach 1:
The patent introduces a valve core seat assembly as an intermediary component that includes integrated fixing structures (both snapping and threaded portions). This assembly acts as a mediator between the side wall branch pipe and the main pipe, absorbing positioning requirements and reducing the precision burden on the piping components themselves.
Solution Approach 2:
By merging snapping fit and threaded connection in one assembly, the patent reduces sensitivity to manufacturing precision. The dual-fixing mechanism compensates for dimensional variations, allowing broader tolerance ranges while preventing leakage through the combined sealing action of both fixing methods.
3Reliability
If high precision processing is performed on side wall branch pipe to achieve proper fitting, then connection reliability improves, but manufacturing cost increases
Solution Approach 1:
The patent segments the connection function into two parts: the side wall branch pipe provides the snapping receptacle, while the valve core seat assembly provides the threaded connection to the main pipe. This segmentation allows each component to have simpler, lower-cost manufacturing requirements while maintaining overall connection reliability through their combined action.
Solution Approach 2:
The valve core seat assembly serves as an intermediary that transfers and distributes connection forces between the side wall branch pipe and main pipe. It includes integrated fixing structures that reduce the precision requirements for the piping components themselves, thereby lowering manufacturing costs while maintaining reliability.
4Strength
If valve core seat is firmly fixed to prevent falling off, then connection strength improves, but device complexity increases
Solution Approach 1:
The patent merges two fixing mechanisms (snapping fit and threaded connection) into a single integrated valve core seat assembly. This combination achieves high connection strength while maintaining relatively simple structure, as both fixing actions are built into one component rather than requiring separate assembly steps or multiple components.

Function Achieved in This Case
The solution provides a robust and cost-effective connection between the valve core seat and the faucet main body, reducing the risk of leakage and manufacturing complexity, while allowing for precise control of water flow and temperature adjustment.
Implementation Method 1
An outer wall of the annular flange is provided with a threaded section, and an inner wall of the main pipe is provided with a second threaded hole; when the valve core seat assembly is installed in the main pipe, and the first threaded hole of the lug of the main body fixing seat is aligned opposite to the second threaded hole, a bolt is threadedly connected into the first threaded hole and the second threaded hole sequentially
Implementation Method 2
a positioning hole is provided in the lug of the main body fixing seat, and a positioning pin is fitted into the positioning hole
Implementation Method 3
a bolt is threadedly connected into the first threaded hole and the second threaded hole sequentially, thereby locking and fixing the main body fixing seat into the main pipe
