Blended Wing Body Cabin With Varying Bay Widths for Reconfiguration
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 affecting those seated near lavatories and restricting cabin reconfiguration flexibility.
Innovation Solution
A blended wing body aircraft design featuring varying bay widths with distinct seating configurations, a central galley complex, and adjustable partitions to accommodate different classes of service, along with a central passage and strategically positioned lavatories, enhancing flexibility and passenger comfort.
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 simplicity is maintained, but space utilization efficiency deteriorates
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 uniform widths. This segmentation allows each bay to be optimized for specific functions, improving overall space utilization while maintaining manageable manufacturing complexity through modular design
Solution Approach 2:
Different bay widths are assigned to different cabin regions based on local requirements. For example, wider bays can accommodate galleys or lavatories while narrower bays are used for seating areas, allowing each local region to have the quality (width) needed for its specific function
2Stability of the object's composition
If fixed positions for galleys and lavatories are used, then structural stability is maintained, but adaptability for different classes of service deteriorates
Solution Approach 1:
The cabin design incorporates adjustable and reconfigurable elements within the bay structure, allowing the configuration to change based on different classes of service requirements while maintaining overall structural stability. The varied bay widths provide flexible zones that can be adapted for different functions
Solution Approach 2:
The bays with different width classifications are designed to serve multiple functions. For example, bays can be configured for seating, galleys, or lavatories depending on operational needs, making the cabin structure universally adaptable to different service classes while maintaining structural integrity
3Ease of operation
If lavatories are positioned within passenger compartments, then ease of access is improved, but passenger comfort deteriorates
Solution Approach 1:
Lavatories are positioned in specific local regions (certain bay classifications) rather than distributed throughout passenger compartments. This localized placement allows optimization of access routes through the bay structure while concentrating lavatory facilities in areas designed for that purpose, reducing negative impact on passenger seating comfort

AI summary
A blended wing body aircraft, comprising a cabin, wherein the cabin comprises a first set of bays comprising a first plurality of seats arranged in a first seating configuration, wherein each bay of the first set of bays is associated with a first bay width, a second set of bays comprising a second plurality of seats arranged in a second seating configuration different than the first seating configuration, a central galley complex positioned in a front center location located between the first set of bays and the second set of bays, a central passage separating the first set of bays, the central galley complex, and the second set of bays, and at least a lavatory positioned outside the first set of bays and the second set of bays, along a perimeter of the cabin.
