Height-Adjustable Floor Drain Connecting Ring with Integrated Sealing and Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current floor drain connection systems face difficulties in installation, height adjustment, and precise positioning due to the use of single-purpose O-rings and drainage rings, which complicate the alignment and adjustment process.
Innovation Solution
A connecting ring made of flexible material with a sealing collar and groove for the O-ring, allowing for universal usage and easy positioning and height adjustment, featuring drainage grooves for water passage control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate O-ring and drainage ring are used, then sealing and drainage functions are achieved, but device complexity increases and installation becomes more difficult
Solution Approach 1:
The patent combines the O-ring sealing function and drainage ring function into a single integrated connecting ring. The connecting ring has an integrated structure where the O-ring groove and drainage channels are built-in, eliminating the need for separate components while maintaining both sealing and drainage capabilities.
Solution Approach 2:
The connecting ring is designed as a universal component that performs multiple functions simultaneously: it provides sealing through the O-ring groove, enables drainage through integrated channels, and allows for height adjustment. This multi-functional design simplifies the overall connection system while maintaining reliability.
2Reliability
If a separate O-ring and drainage ring are used, then sealing and drainage functions are achieved, but ease of operation deteriorates due to difficult positioning and height adjustment
Solution Approach 1:
By merging the positioning features and height adjustment mechanisms into the single connecting ring structure, the patent enables straightforward installation. The integrated design allows the component to be positioned and adjusted in one operation rather than requiring coordination of multiple separate parts.
3Reliability
If multiple single-purpose rings are used, then specific functions are fulfilled, but adaptability deteriorates as different ring types must be selected
Solution Approach 1:
The connecting ring is designed as a universal component that performs multiple functions simultaneously: it provides sealing through the O-ring groove, enables drainage through integrated channels, and allows for height adjustment. This multi-functional design simplifies the overall connection system while maintaining reliability.
4Reliability
If an O-ring connection is used, then sealing is achieved, but ease of operation deteriorates due to difficulty in checking correct positioning
Solution Approach 1:
The patent incorporates visual indicators (such as colored markings or visible alignment features) on the connecting ring that change or become apparent when the component is correctly positioned. This allows installers to easily verify proper installation without complex measurement tools.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables simple and precise installation and height adjustment of the drainage extension or gutter, allowing for universal application with either O-ring or without, improving the overall efficiency of water drainage.
Implementation Method 1
The flexible material of the connecting ring can be an elastomer, or rubber
Implementation Method 2
At the opening, between the outer side of the ring and the inner side of the drain body, there is a drainage groove

AI summary
The connecting ring (1) for floor drains is mounted between the drain body (2) and the drain extension (3). There is in its upper part on the outside fitted with a sealing collar (1.1) with at least one opening (1.6) to allow water to pass through; on the inside, the sealing ring is fitted with a sealing lip (1.3), and in the bottom part it is equipped with a groove (1.5) for the O-ring (1.2). A drainage groove (1.4) is situated at the opening (1.6), between the outer side of the ring (1) and the inner side of the drain body (2).
