Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercially available ventilation modules for pipeline systems have a large vertical extent, making them unsuitable for installation in areas with suspended ceilings, such as modernized bathrooms, where maintaining original room height is crucial.
Innovation Solution
A compact pipeline venting device with a low vertical height is designed, featuring an impact surface and two gently rising riser channels that open into a common annular chamber, promoting turbulent flow and separation of harmful fluids, along with a horizontal chamber to further reduce vertical height and enhance space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a conventional ventilation module is used to effectively separate harmful fluid from useful liquid, then the separation function is achieved, but the vertical height becomes too large for installation under suspended ceilings
Solution Approach 1:
The patent transitions from a vertically-oriented separation module to a horizontally-oriented design. The liquid flow path is arranged horizontally through the housing, with the separation chamber extending in the horizontal direction rather than vertically. This dimensional change allows the module to fit under suspended ceilings while maintaining effective separation functionality through the horizontally arranged impact surface, riser channels, and separation chamber.
2Length of stationary object
If the vertical height is reduced to enable installation under suspended ceilings, then installation flexibility is improved, but the bubble-out efficiency of harmful fluid may be compromised
Solution Approach 1:
The patent compensates for reduced vertical height by extending the separation path horizontally. The liquid flows horizontally through riser channels that rise gently upward, creating turbulence and promoting bubble separation along the horizontal flow path. The impact surface is positioned to create turbulent flow conditions that enhance bubble-out efficiency without requiring large vertical space.
Solution Approach 2:
The patent modifies flow parameters by designing riser channels with gentle upward inclination rather than vertical rise. This changes the flow regime to create optimal turbulence for bubble separation while maintaining a compact vertical profile. The horizontal extension of the separation chamber provides sufficient residence time for bubble separation to occur effectively.
3Length of stationary object
If a compact horizontal design is implemented to reduce vertical height, then installation space is improved, but the device complexity increases due to the need for impact surfaces and riser channels
Solution Approach 1:
The patent combines multiple functions into integrated components. The impact surface serves both as a flow distributor and as a turbulence generator for bubble separation. The riser channels simultaneously convey liquid horizontally and provide the upward inclination needed for bubble separation. The separation chamber integrates the horizontal flow path with the bubble-out function, eliminating the need for separate components for each function.
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 device effectively separates harmful fluids from useful liquids, maintaining a low vertical profile while ensuring efficient venting, allowing for installation in limited spaces and promoting bubble-out properties, thus preserving room height during modernization.
Implementation Method 1
After entering the housing, the liquid permeated with the harmful fluid first hits the impact surface. This creates a turbulent flow situation that promotes the escape of the harmful fluid.
Implementation Method 2
a volume-changing body (18), which closes the ventilation opening (17) of the housing in a first operating position and opens it in a second operating position, wherein the volume-changing body (18) is in an operative connection with the useful liquid in such a way that the ventilation opening (17) is closed when a service liquid fill level reaches a target fill level height
