Drain Pipe Connector With Deflected Air Intake Against Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-intake valves in sanitary equipment often malfunction due to material settlement, leading to leaks or clogging during the evacuation of contaminated water, as they may seize up or lose elasticity, resulting in poor sealing and inefficient drainage.
Innovation Solution
A connector for pipes with a sleeve member and deflecting wall that separates the pipe into a water flow part and an air intake part, ensuring reliable air introduction during water evacuation while protecting the air intake orifice from dirt and maintaining proper flow, preventing desiphoning and clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a movable valve is used to control air intake, then air can be introduced during evacuation, but the valve may seize up or lose elasticity causing leaks or clogging
Solution Approach 1:
The patent removes the movable valve mechanism entirely and replaces it with a fixed air intake orifice. The deflecting wall is positioned to allow air passage when water is evacuated while preventing water leakage, eliminating the complexity and reliability issues of movable parts.
Solution Approach 2:
The connector is divided into distinct functional zones: a water flow channel and an air intake orifice. The deflecting wall creates spatial separation between water and air pathways, allowing each to function independently without requiring complex control mechanisms.
2Productivity
If the valve is positioned to allow air intake, then evacuation is improved, but dirty water may leak through the orifice
Solution Approach 1:
The deflecting wall is specifically shaped and positioned to create different flow conditions at different locations. At the air intake orifice location, the wall geometry allows air passage while the angled surface redirects water flow away from the orifice, providing location-specific functionality.
Solution Approach 2:
The deflecting wall acts as an intermediary element between the water flow and air intake orifice. It mediates the interaction by allowing air to pass through while preventing water from reaching the orifice, solving the contradiction between air intake and water sealing.
3Reliability
If materials in dirty water settle around the valve, then the valve may malfunction, but removing the valve eliminates air intake control
Solution Approach 1:
The patent extracts the movable valve component that is susceptible to material settlement and replaces it with a fixed orifice design. The deflecting wall provides the necessary flow control without requiring movable parts that can malfunction.
Solution Approach 2:
The deflecting wall automatically responds to water flow conditions without requiring external control. When water flows, the wall geometry naturally directs it away from the air orifice; when water is not present, air can freely enter through the orifice.
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
The solution ensures effective air introduction during water evacuation, preventing leaks and clogging, while maintaining efficient water flow and easy installation, integration into existing sanitary equipment, and providing inspection access for maintenance.
Implementation Method 1
a deflector wall extending from a first end located between the water inlet opening and the air intake orifice, the member jacket dividing the tubing into a first water flow part and a second air intake part in the fitting
Implementation Method 2
the air intake orifice opening into the second air intake part... a flow of air to enter the tubing, in order to facilitate the evacuation of water from sanitary equipment and to avoid any risk of desiphoning
Implementation Method 3
the connector also comprises a leg making it possible to hold apart a free end of the deflecting wall of the tubing
