Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft waste separation systems are large, heavy, require excessive space, and frequent servicing, and often fail to consistently prevent moisture escape in the airstream, posing challenges in compactness, weight efficiency, and maintenance accessibility.
Innovation Solution
A multiple vortex separator system with a cylindrical housing, annular channel, nested inverted cones, and a helix isolator that uses centrifugal force to separate liquid and solid waste from the airstream, ensuring a moisture-free exhaust through a combination of vortex paths and filter units, and is designed for easy installation and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional waste separation systems are used, then waste can be separated from the airstream, but the systems are large, heavy, and require excessive space in the aircraft
Solution Approach 1:
The patent combines multiple separator functions into a single integrated apparatus. The first separator and second separator are merged into one unit, with the second separator positioned inside the first separator, creating a compact multi-functional device that reduces overall weight and space requirements while maintaining effective waste separation
Solution Approach 2:
The second separator is nested within the first separator, with the conical separator positioned inside the cylindrical separator housing. This nested configuration allows both separation stages to coexist in a compact arrangement, significantly reducing the overall footprint and weight compared to conventional separate separator systems
2Reliability
If conventional waste separation systems are used, then waste can be separated, but the systems require excessive space in the aircraft
Solution Approach 1:
The second separator is nested within the first separator, with the conical separator positioned inside the cylindrical separator housing. This nested configuration allows both separation stages to coexist in a compact arrangement, significantly reducing the overall footprint and weight compared to conventional separate separator systems
Solution Approach 2:
The invention transitions from a horizontal arrangement of separate separators to a vertical nested configuration. The first separator has a cylindrical housing with vertical orientation, and the second conical separator is nested within it, utilizing vertical space more efficiently and reducing the horizontal area occupied by the separator system
3Reliability
If conventional waste separation systems are used, then waste can be separated, but the systems require frequent servicing that is difficult and time-consuming
Solution Approach 1:
The separator apparatus is divided into distinct modular components including the first separator, second separator, filter unit, and housing. These segmented components can be independently accessed and serviced, allowing maintenance personnel to service individual parts without disassembling the entire system, thereby reducing servicing time and complexity
Solution Approach 2:
The separator apparatus incorporates removable and replaceable components such as the filter unit and separator elements. These dynamic components can be quickly removed and replaced during maintenance operations, significantly reducing servicing time compared to fixed conventional separator systems that require complete disassembly for maintenance
4Reliability
If conventional waste separation systems are used, then waste can be separated under optimal conditions, but moisture may still escape in the airstream
Solution Approach 1:
The patent employs different separator geometries in different locations within the system. The first separator uses a cylindrical configuration while the second separator uses a conical shape, creating locally optimized flow patterns that enhance moisture removal at different stages of the separation process
Solution Approach 2:
The separator apparatus implements continuous multi-stage separation with the first separator followed by the second nested separator. This continuous action ensures that moisture removal is maintained throughout the entire separation process, preventing moisture escape in the exhaust airstream more reliably than single-stage conventional systems
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 system effectively separates waste from the airstream, minimizing moisture escape and weight, while being compact and lightweight, facilitating easy maintenance and installation in limited aircraft spaces, ensuring sanitary and safe operation.
Implementation Method 1
The separator of the invention includes a housing, which is preferably cylindrical in shape, and has a waste inlet for receiving the waste stream... An annular channel is positioned along the inner surface of the cylindrical wall of the housing. This channel defines a first vortex path for separating liquid and solid waste from the waste stream
Implementation Method 2
The suction that transports the waste material to a waste tank is usually provided by a vacuum generator when the aircraft is on the ground or at low altitudes... the pressure differential between the exterior atmosphere and the interior of the aircraft to draw the waste material
Implementation Method 3
a multiple vortex separator for drawing a substantially moisture-free airstream from a waste stream containing liquid and solid waste... exhaust port for drawing the substantially moisture-free airstream from the housing by way of suction force

AI summary
A vortex separator for drawing a substantially moisture-free airstream from a waste stream having an annular channel defining a first vortex flow path for separating liquid and solid waste from this waste stream and preferably a filter unit with an inverted conical cavity between nested inverted cones defining a second vortex flow path that is isolated from the first vortex flow path for separating additional liquid and solid waste from the waste stream before it exits the vortex separator. In preferred embodiments, the separator includes a removable filter unit cartridge positioned within the outer cone and a helix isolator to respectively make use of the separator more convenient to use and more efficient.
