Metal Faucet Outlet Neck Curved Stopping Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Metal faucets with sharp edges and small contact areas between the outlet neck and sealing ring lead to leakage and structural issues, while inner rings can block water flow and obstruct moderating plates.
Innovation Solution
An improved metal faucet outlet neck design featuring a curved stopping ring with a rounded surface, a locking member, and a sealing ring that increases contact area and structural strength, along with a moderating plate with a limiting aperture to prevent leakage and enhance water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a typical opening design with small contact area is used, then the structure is simple, but the sealing ring tends to escape and causes leakage
Solution Approach 1:
The patent applies curvature by designing the stopping ring with a rounded inner edge instead of a sharp edge. This curved geometry increases the contact area with the sealing ring, providing better sealing performance and preventing the sealing ring from escaping, while maintaining structural simplicity
Solution Approach 2:
The patent introduces a stopping ring as an additional dimensional element within the opening structure. This stopping ring with its rounded inner edge creates a new contact dimension between the opening and the sealing ring, enhancing sealing without significantly complicating the overall structure
2Strength
If the outlet neck thickness is increased to prevent cracking, then the structural strength is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent applies preliminary action by designing the opening with a rounded inner edge and stopping ring structure before the engagement and torque application. This pre-designed feature distributes the torque stress evenly, preventing cracking during assembly without requiring increased outlet neck thickness
Solution Approach 2:
The patent changes the geometric parameters of the opening by introducing a rounded inner edge with specific radius and a stopping ring structure. This parameter modification allows the opening to withstand engagement torque without cracking, maintaining the original outlet neck thickness and simplifying manufacturing
3Reliability
If an inner ring is added to prevent disengagement, then the sealing reliability is improved, but the water flow is blocked and causes water splash
Solution Approach 1:
The patent uses a rounded inner edge design instead of a protruding inner ring. This curved geometry prevents water flow blockage and eliminates water splash while still providing the necessary sealing function by increasing contact area with the sealing ring
4Reliability
If an inner ring is used to prevent disengagement, then the sealing is improved, but the moderating plate installation is obstructed
Solution Approach 1:
The patent extracts the problematic inner ring structure and replaces it with a rounded inner edge design combined with a stopping ring. This extraction eliminates the obstacle to moderating plate installation while maintaining sealing performance through the rounded geometry that increases contact area
