Aircraft Waste Bin Extractor Platform Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft galley waste bins are difficult to remove safely and efficiently, leading to back strain and safety concerns for flight attendants due to their heavy weight and inadequate securing methods, which fail to prevent rattling during flight.
Innovation Solution
A waste bin and compartment extractor system featuring a side wall that drops down to form a platform, allowing the bin to be slid or rolled down a ramp for easy removal without lifting, incorporating wheels for mobility and a ramp to prevent rattling and facilitate safe emptying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the waste bin is rigidly secured to prevent shifting during flight, then the bin is securely held and rattling is prevented, but the bin becomes difficult to extract for emptying
Solution Approach 1:
The side wall is designed to be dynamically changeable between a secured position (during flight) and an extracted position (for emptying). The side wall can be moved from a vertical secured position that holds the bin firmly, to a horizontal extracted position that forms a platform for easy bin removal. This dynamic transformation resolves the contradiction by providing both secure holding during flight and easy extraction when needed.
2Reliability
If the waste bin is kept in the lower half of the compartment for stable storage, then the bin is securely positioned, but flight attendants experience back strain when lifting it for emptying
Solution Approach 1:
The extracted side wall creates a platform at the same level as the bin, eliminating the height difference that causes back strain. Flight attendants can access the bin at waist level rather than bending down to lift it from the lower compartment, making the emptying process ergonomic and safe while maintaining stable storage during flight.
3Ease of operation
If the waste bin is designed to be easily movable for emptying, then extraction is simple, but the bin may shift or rattle during flight
Solution Approach 1:
The side wall's dynamic positioning provides rigid support during flight to prevent shifting, then transforms to facilitate easy extraction. When vertical, it secures the bin; when horizontal, it creates an open platform for simple bin removal. This resolves the contradiction between stability during flight and ease of extraction.

AI summary
An aircraft galley waste bin extraction unit is disclosed having a first compartment formed by a plurality of walls that conform with walls of the waste bin, an extraction chamber adjoining the first compartment and sharing a common wall, and a platform within the common wall including a hinged bottom edge that allows the platform to pivot into a horizontal position against a rest on an extraction chamber side wall, the deploying of the platform forming a window through which the waste bin can pass through from the first compartment to the extraction chamber. The unit preferably also includes retractable ramp extendable from the platform to a ground surface to guide the waste bin from the extraction unit to the ground.
