Blended Wing Body Cabin Layout With Varying Bay Widths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft cabin designs with uniform bay widths and fixed positions for galleys and lavatories lead to inefficiencies in space utilization and passenger comfort, particularly due to discomfort from lavatories near seating and restricted cabin reconfiguration.
Innovation Solution
A blended wing body aircraft with varying bay widths, featuring a first set of bays with a specific seating configuration and bay width for premium classes, a second set of bays with a different configuration for economy class, a central galley complex, and adjustable partition walls to optimize space and comfort, along with modular seating arrangements and sound-dampening materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uniform bay widths and fixed positions for galleys and lavatories are used, then manufacturing and design simplicity is maintained, but space utilization efficiency and passenger comfort deteriorate
Solution Approach 1:
The cabin is divided into multiple bays with different width classifications (first bay width, second bay width, third bay width) rather than using a uniform width throughout. This segmentation allows each bay to be optimized for its specific function, improving space utilization while maintaining manageable design complexity through modular construction approaches
Solution Approach 2:
Different bay widths are assigned to different locations within the cabin based on local requirements. First bays have a first width suitable for certain functions, second bays have a second width for other functions, and third bays have a third width for additional functions. This local differentiation optimizes space utilization for each specific area while the overall design follows standardized manufacturing principles
2Ease of operation
If lavatories are positioned within passenger compartments, then accessibility is improved, but passenger comfort deteriorates due to discomfort for seated passengers
Solution Approach 1:
Lavatories are extracted from the traditional location within passenger compartments and repositioned to alternative locations within the cabin structure. This separation removes the source of discomfort from the passenger seating areas while maintaining accessibility through strategic positioning in the reconfigured cabin layout with varying bay widths
Solution Approach 2:
The cabin layout is reconfigured by utilizing the varying bay widths to create a three-dimensional optimization of space. Lavatories are positioned in bays with appropriate width characteristics, and the central passage is arranged to provide accessibility from multiple directions, effectively using spatial dimensionality to resolve the conflict between accessibility and comfort
3Device complexity
If fixed positions for galleys are used, then structural simplicity is maintained, but cabin reconfiguration flexibility deteriorates
Solution Approach 1:
The cabin structure incorporates dynamic elements through the varying bay widths that can accommodate different configurations. While the overall bay structure provides structural simplicity, the different width classifications allow for flexible reconfiguration of galley positions and other cabin elements to meet changing operational requirements
Solution Approach 2:
The varying bay widths create universal spaces that can serve multiple functions. Bays with different width characteristics can be configured for different purposes (galley, lavatory, seating, storage) depending on operational needs, providing multi-functionality while maintaining a relatively simple underlying structural framework
