Height-Adjustable Urinal Siphon for Variable Wall Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urinal installations face challenges with precise alignment of inlet and outlet openings, requiring careful measurement and potential rework during installation and replacement, especially in environments with limited space and design constraints.
Innovation Solution
A height-adjustable urinal siphon mechanism with plug-in tube sections and a circumferential sealing ring allows for variable distance adjustment between the inlet and outlet openings, enabling flexible installation and maintenance without compromising the odor trap function or aesthetic design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the distance between inlet and outlet openings is fixed, then the manufacturing precision is improved, but the adaptability deteriorates
Solution Approach 1:
The siphon incorporates an adjustable height mechanism that allows the distance between the inlet opening and outlet opening to be dynamically changed. This enables the urinal to adapt to different wall connection heights while maintaining proper installation, resolving the contradiction between fixed manufacturing precision and needed adaptability.
Solution Approach 2:
The invention changes the parameter of the siphon's height dimension, allowing adjustment of the distance between inlet and outlet openings. This parameter change enables adaptation to various installation scenarios without requiring precise pre-determination of wall connection heights.
2Ease of operation
If the wall connections are made with high precision, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The siphon is divided into multiple segments or components that can be adjusted independently. This segmentation allows for simple height adjustment mechanisms that do not significantly increase overall device complexity while improving ease of installation.
Solution Approach 2:
The height adjustment mechanism is designed to be self-contained within the siphon structure, allowing installers to make adjustments without requiring specialized tools or complex procedures. The mechanism serves itself by incorporating the adjustment capability directly into the siphon body.
3Reliability
If the odor trap is positioned deep below the pool, then the reliability is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The odor trap's position is made dynamically adjustable through the height-adjustable siphon mechanism. This allows the odor trap to be positioned at the optimal depth for reliable functionality while accommodating variations in pool depth and wall connection heights, improving both reliability and ease of manufacture.

AI summary
The urinal (1) is provided with an inlet opening (6) and a drain port (7), where the distance (h1) between the inlet opening and the drain port is variable. A variable distance setting device is located within the outer contour of the urinal. The variable distance setting device is formed with an odor seal (13). An independent claim is also included for an adjustable urinal siphon.
