Trolley Fluid Container for Separate Liquid Waste Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waste collection systems in vehicles, particularly aircraft, face challenges in efficiently separating and compacting solid and liquid waste due to the mixing of waste types, leading to inefficient disposal and storage issues.
Innovation Solution
A fluid receiving container with a check valve and separate collection system is integrated into a trolley, allowing for the separation of liquid waste from solid waste during collection, enabling efficient extraction and storage of liquids, and maintaining the compact shape of the waste enclosure for easier handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If solid waste and liquid waste products are collected in a common garbage bag, then the collection process is simplified, but the waste products require elaborate separation prior to disposal and the fluid content limits compaction
Solution Approach 1:
The waste collection system is segmented into two separate functional containers: a fluid receiving container for liquid waste and a waste enclosure for solid waste. This segmentation eliminates the need for post-collection separation while maintaining operational simplicity, as each container type handles its designated waste type without mixing
2Volume of moving object
If air is extracted from the garbage bag to increase compaction, then the volume is reduced, but the compaction is still limited by the fluid content of the waste products
Solution Approach 1:
By segmenting waste into liquid and solid streams, the system allows the solid waste enclosure to be compacted effectively through air extraction without the compaction-limiting fluid content that would be present in a mixed waste bag
Solution Approach 2:
Liquid waste is extracted from the waste stream into a separate fluid receiving container, removing the fluid content that would otherwise prevent effective compaction of solid waste through air extraction
3Loss of energy
If waste products are stored aboard the vehicle for disposal at a target location, then disposal fees are reduced, but the storage capacity is insufficient in vehicles with many passenger seats
Solution Approach 1:
The segmented container system maximizes storage efficiency by separating liquids and solids, allowing each compartment to be optimized for its specific waste type and enabling more effective use of the limited storage space available in passenger vehicles
Solution Approach 2:
The system changes the physical state parameters of stored waste by separating liquids from solids, allowing the solid waste to be compacted to a higher density while liquids are stored in their natural state, thereby increasing overall storage capacity
