Floor Drain With Adjustable Height And Variable Immersion Pipe
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in designing a floor-level shower drain with an odor trap is the limited space available for installation, which restricts the flexibility in adjusting the overall height, water seal height, and drainage capacity, especially in old building renovations where structural integrity and low screed heights are concerns.
Innovation Solution
A drain system with an adjustable bottom part and immersion pipe that can be customized in height and length, allowing for variable settings of overall height, water seal height, and drainage capacity through screw threads, annular seals, and cutting of the immersion pipe, ensuring a liquid-tight connection and enhanced outflow performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional floor drain with fixed parameters is used, then the structure is simple and easy to manufacture, but the adaptability to different installation situations is poor
Solution Approach 1:
The base part is made adjustable in height relative to the drain body through a threaded connection mechanism, allowing the overall height to be dynamically adapted to different installation situations such as varying screed heights and floor levels, while maintaining a relatively simple structural design
Solution Approach 2:
The drain is divided into separable components including the drain body, adjustable base part, and immersion pipe, allowing independent adjustment of each component's position and height to achieve optimal adaptation to different installation environments
2Productivity
If the immersion pipe is made longer to increase drainage capacity, then the drainage capacity improves, but the overall height increases which is not suitable for low screed height requirements
Solution Approach 1:
The immersion pipe length is made variable rather than fixed, allowing it to be cut to the required length during installation to achieve the desired drainage capacity while maintaining the overall height within acceptable limits for low screed height applications
Solution Approach 2:
The length parameter of the immersion pipe can be changed by cutting it to different lengths, enabling optimization of drainage capacity independently of the overall drain height, which is determined by the adjustable base part
3Length of stationary object
If the base part is made adjustable in height, then the adaptability to different installation heights improves, but the device complexity increases
Solution Approach 1:
The adjustment mechanism uses simple threaded connections instead of complex mechanical systems, allowing height adjustment through basic screwing and unscrewing actions, thereby achieving adaptability to different installation heights while minimizing the increase in device complexity
Solution Approach 2:
The threaded connection between the base part and drain body provides self-adjusting capability, allowing installation personnel to easily modify the height setting during installation without requiring specialized tools or complex adjustment procedures

AI summary
The drain (1) has an immersion pipe (2) inserted into a cup-like drain housing (1.1) via a supply opening (1.3) and defining an odor trap with the housing. A shell or cup-like bottom part (1.2) is connected with drain housing in height-adjustable and liquid-tight manner. The immersion pipe is shortened for reducing an axial length by separating an immersion pipe section (2.2). The bottom part and the housing include threads that are screwed with each other. An annular groove is provided in the housing. A seal is inserted in the annular groove.
