Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tube and wing aircraft have limited cabin design flexibility due to uniformity, resulting in similar seat orientations that restrict variability and efficiency in passenger cabin layouts.
Innovation Solution
A blended wing body (BWB) aircraft design with integrated passenger bays oriented along the longitudinal axis and leading edges, allowing for varied seat configurations and increased space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional tube and wing aircraft use uniform seat orientations to maximize space and efficiency, then space utilization and operational efficiency are improved, but cabin design flexibility and variability are reduced
Solution Approach 1:
The passenger cabin is divided into multiple independently orientable passenger bays (first passenger bay, second passenger bay, etc.) that can be configured in different orientations. Each bay can be aligned with the longitudinal axis or leading edges, allowing flexible cabin layouts while maintaining efficient space utilization through systematic segmentation of the seating arrangement.
Solution Approach 2:
The patent introduces asymmetric orientation options for passenger bays, where bays can be positioned at different angles relative to the aircraft body (e.g., parallel to longitudinal axis vs. parallel to leading edges). This asymmetric configuration capability enables diverse cabin designs and passenger experiences while optimizing space usage in the blended wing body structure.
2Ease of manufacture
If passenger bays are oriented parallel to the longitudinal axis only, then structural simplicity and manufacturing ease are improved, but cabin layout variety and passenger comfort options are reduced
Solution Approach 1:
The patent implements dynamic orientation capability for passenger bays, allowing them to be configured in multiple orientations (parallel to longitudinal axis or parallel to leading edges) based on operational requirements. This dynamic reconfigurability provides seat configuration variety while maintaining relatively simple bay structures that can be manufactured using standard processes.
Solution Approach 2:
The passenger bay structure is designed as a universal module that can serve multiple functions by being oriented in different directions. The same basic bay design can be used in both longitudinal and leading-edge orientations, providing multi-functionality and layout variety without requiring entirely different structural components for each configuration type.
3Loss of energy
If blended wing body aircraft use integrated wing-body structure, then aerodynamic efficiency and fuel economy are improved, but cabin design constraints and structural complexity are increased
Solution Approach 1:
The integrated blended wing body structure is segmented into functional zones including passenger bays, cargo compartments, and structural elements. This segmentation allows the complex integrated structure to be designed and manufactured more effectively while maintaining aerodynamic efficiency. The passenger bays themselves are segmented into multiple orientable units that can be independently configured within the integrated body.
Solution Approach 2:
The patent applies local quality variations within the blended wing body structure, where different regions have optimized properties for their specific functions. Passenger bays have localized structural characteristics suited to their orientation and function, while the overall integrated structure maintains aerodynamic optimization. This allows complex internal configurations without compromising external aerodynamic efficiency.
