Ball Valve Connection Structure for Leak-Safe Sink Drain Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ball valve connection structures in water sinks suffer from difficult maintenance, dirt accumulation, and water leakage due to the complex interconnection of the ball valve, positioning ring, and filtration cap, leading to unflatness and removal issues.
Innovation Solution
A connection structure comprising a hollow body with separate connecting, coupling, and fixing portions, a spherical ball valve with a guide orifice, and a positioning ring with washers, allowing easy assembly and detachment, while preventing water leakage and dirt accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ball valve, positioning ring, and filtration cap are connected in turn, then the ball valve can control water flow, but the connection becomes troublesome and difficult to maintain
Solution Approach 1:
The patent integrates the ball valve, positioning ring, and filtration cap into a single unified assembly where the ball valve is received within the positioning ring, which is itself received in the body. This merging eliminates the need for separate connections between each component, making the structure simpler while maintaining water flow control functionality.
Solution Approach 2:
The patent divides the assembly into distinct receiveable components: the body receives the positioning ring, which receives the ball valve. This segmentation allows for easy maintenance and disconnection of individual parts without affecting the entire assembly, resolving the complexity issue while preserving functionality.
2Ease of manufacture
If the filtration cap is positioned to contact the positioning ring, then assembly is simplified, but the filtration cap becomes unflat and removes easily causing dirt accumulation
Solution Approach 1:
The patent extracts the filtration cap from direct contact with the positioning ring, allowing the filtration cap to be positioned independently within the body. This prevents the unflatness and removal issues caused by contact with the positioning ring, while the body provides stable support for the filtration cap.
3Reliability
If the ball valve and positioning ring are tightly connected, then water leakage is prevented, but maintenance and disconnection become difficult
Solution Approach 1:
The patent creates a dynamic receiveable connection where the ball valve is received within the positioning ring, allowing for both tight connection during operation (preventing leakage) and easy extraction during maintenance. The receiveable structure provides flexibility between operational stability and maintenance accessibility.

AI summary
A connection structure of a ball valve of a control valve for draining water out of a water sink contains: a body, a filtration cap, the ball valve, a handle bar, and a positioning ring. The body includes a first connecting portion configured to connect with the filtration cap, a second connecting portion configured to accommodate the ball valve, a coupling portion, and a fixing portion. The filtration cap includes multiple filtering orifices configured to guide wasted water into the body. The ball valve is spherical and is received in the second connecting portion, and the includes a guide orifice passing and a connection portion. The handle bar is inserted into the coupling portion and connected with the connection portion so that the handle bar is engaged by the handle bar to be turned on/off. The positioning ring is received in the fixing portion.
