Solution Overview

Problem

In ride-sharing aircraft, passengers may not know each other and privacy is a concern due to lack of angled seating configurations.

Innovation Solution

Aircraft with angled seating away from each other, separated by a divider, and doors that open simultaneously to provide access to both passenger cabin and cargo hold, ensuring privacy and ease of ingress/egress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional straight-row seating is used, then aircraft design is simple and certification is straightforward, but passenger comfort and safety during turbulence are reduced

Engineering Contradiction:
Improvepassenger safety and comfortVSAvoidseating configuration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies asymmetry by configuring seats in a staggered diagonal pattern rather than traditional straight rows. Each row contains seats at different longitudinal positions (e.g., 2-2 configuration where seats are offset), creating an asymmetric layout that reduces turbulence impact while maintaining structural simplicity. This asymmetric arrangement allows passengers to be positioned at varying distances from the aircraft center of gravity, improving comfort without complex mechanisms.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The invention transitions from the traditional one-dimensional row-based seating arrangement to a two-dimensional staggered grid pattern. Seats are distributed across both lateral and longitudinal dimensions, creating a diagonal seating matrix. This dimensional change optimizes the distribution of passengers relative to the aircraft's center of gravity and turbulence vectors, enhancing safety and comfort while preserving structural simplicity for certification purposes.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If angled or staggered seating is implemented, then passenger comfort and safety are improved, but aisle access and emergency evacuation become more difficult

Engineering Contradiction:
Improvepassenger safetyVSAvoidaisle access and evacuation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The seating arrangement is segmented into distinct sections with dedicated aisle access points. Each staggered row is designed with sufficient lateral clearance to maintain unobstructed aisle pathways. The segmentation allows passengers to access aisles at multiple locations along the cabin, ensuring that emergency evacuation routes remain clear and accessible despite the angled seating configuration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The seat design incorporates pre-configured aisle access pathways and emergency exit provisions into the staggered layout. During the design phase, adequate spacing and clearance are built into the seating arrangement to ensure that passengers can quickly and easily access aisles and emergency exits without requiring additional mechanical systems or complex procedures during evacuation.

3Ease of operation

If seats are angled relative to aircraft centerline, then forward visibility and comfort are improved, but structural design and certification complexity increase

Engineering Contradiction:
Improvepassenger comfort and visibilityVSAvoidstructural design complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent employs asymmetric angle configurations for seats relative to the aircraft centerline. Rather than uniform symmetric angles, the design uses varied angles optimized for each seating position to maximize forward visibility and comfort. This asymmetric angular arrangement improves passenger experience while the overall pattern maintains regularity that simplifies structural design and certification documentation.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

Different sections of the aircraft cabin utilize locally optimized seat angles tailored to specific operational requirements and passenger flow patterns. Each local seating zone is configured with angles optimized for its particular function (e.g., forward-facing angles in cockpit rows, angled configurations in passenger cabins), allowing maximum comfort and visibility while maintaining overall structural simplicity through localized rather than globally complex design.

Inventive Principle:
Principle #3Local quality

AI summary

An aircraft that includes a body that defines a cabin interior and a longitudinal axis, and a front row positioned in the cabin interior. The front row includes a first front seat and a second front seat. The first and second front seats are angled away from one another. The first front seat is angled outwardly such that it forms a first acute angle with the longitudinal axis and the second front seat is angled outwardly such that it forms a second acute angle with the longitudinal axis. The first and second acute angles are approximately the same.
