Crew Rest Bed Supported by a Stowable Flight Attendant Seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passenger aircraft cabin designs lack efficient and space-saving solutions for providing crew rest areas without occupying passenger seating and requiring additional support structures for sleeper berths.
Innovation Solution
A cabin section with adjustable flight attendant seats that convert into stowed positions to support sleeper berths, utilizing the seat surfaces as support points, and incorporating a storage cabinet with foldable sleeping surfaces, which can be quickly deployed and stowed, creating a compact crew rest compartment with privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bed is provided in the business class seat area, then passenger comfort and service quality are improved, but the risk of foreign objects falling into the engine intake is increased
Solution Approach 1:
A screen is introduced as an intermediary barrier between the business class bed area and the engine intake. The screen prevents foreign objects from the bed area from entering the engine intake, while allowing the bed functionality to remain operational for passenger comfort.
2Area of stationary object
If the bed is positioned close to the engine intake, then space utilization is improved, but the risk of foreign objects entering the engine is increased
Solution Approach 1:
The screen acts as a mediator that allows the bed to be positioned close to the engine intake for optimal space utilization, while simultaneously preventing foreign objects from reaching the engine intake.
3Reliability
If a screen is installed to prevent foreign objects, then engine safety is improved, but the aesthetic appearance and space are reduced
Solution Approach 1:
The screen is designed with adjustable parameters including transparency and positioning. This allows the screen to provide engine safety protection while minimizing impact on aesthetic appearance through parameter optimization.
4Ease of manufacture
If the bed structure is simplified, then manufacturing cost is reduced, but the stability and foreign object prevention capability are weakened
Solution Approach 1:
The bed structure is segmented into modular components including the bed unit, screen, and mounting structures. This segmentation allows for simplified manufacturing of individual components while maintaining the overall stability and foreign object prevention capability of the complete system.
