Drain Structure Connecting Sleeve Thread Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing urinal drainage systems require complex connections and significant manpower for assembly, as they necessitate a connecting member with both internal and external threads, making the mounting process inconvenient and labor-intensive, especially for fully enclosed urinals.
Innovation Solution
A drain structure featuring a connecting sleeve with an external thread and internal thread on the drain bent pipe end, allowing direct screwing into the urinal trough without a connecting member, facilitated by sleeve wall protrusions and grooves for wrench tool operation, enabling single-person mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connecting member with internal thread and external thread is used to connect the drain valve body to the sink trap, then the connection is secure, but the device complexity increases and the mounting process becomes more difficult
Solution Approach 1:
The patent merges the connecting member with the drain valve body by integrating the external thread directly onto the drain valve body outlet. This eliminates the need for a separate connecting member with dual threads, reducing structural complexity while maintaining secure connection functionality through the integrated threading system.
2Reliability
If the sink trap, drain valve, and urinal are assembled together in advance, then the connection is secure, but the weight increases and requires multiple persons for mounting
Solution Approach 1:
The patent segments the drainage system into separate modular components: the urinal, the drain bent pipe, and the connecting sleeve with integrated thread. This allows each component to be lightweight and easily handled individually, while still achieving secure connections through the integrated threading system, eliminating the need for pre-assembly of heavy components.
3Reliability
If a connecting member is used for connection, then the connection is secure, but the number of parts increases and assembly time increases
Solution Approach 1:
The patent combines the connecting member functionality directly into the drain valve body through integrated external threading. This reduces the total number of parts from multiple separate components (connecting member, drain valve body, sink trap) to fewer integrated components, thereby reducing assembly time and the number of assembly steps required while maintaining secure connection reliability.

AI summary
A drain structure includes a drain bent pipe configured to drain a urinal trough. The drain bent pipe includes a bent pipe main body; a first bent pipe end connected to a first end of the bent pipe main body; a second bent pipe end connected to a second end of the bent pipe main body; and an internal thread disposed in the first bent pipe end. The drain structure also includes a connecting sleeve configured to connect the urinal trough to the drain bent pipe. The connecting sleeve includes a sleeve main body including an external thread configured to be screwed into the first bent pipe end.
