Solution Overview

Problem

Prior art long haul premium aircraft accommodations provide limited sleeping comfort and privacy due to narrow and short beds with exposed hard surfaces, restricting passenger movement and orientation, and inadequate privacy.

Innovation Solution

A premium class aircraft passenger suite with adjustable surfaces, including a second armrest assembly and bed extension, forming a large, continuous bed that occupies the entire living area, along with a privacy screen for enhanced privacy and comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If only the seat is used to form the bed, then the device complexity is reduced, but the bed surface area is limited and sleeping comfort deteriorates

Engineering Contradiction:
Improvestructure complexityVSAvoidbed surface area
Core Design Contradiction:
Device complexityVSArea of moving object

Solution Approach 1:

The patent combines multiple suite surfaces (seat back, seat bottom, ottoman, armrests, and bed extension) to form a unified bed structure. This merging of previously separate surfaces creates a large continuous sleeping area that covers substantially the entire floor space of the passenger living area, resolving the contradiction between structural simplicity and bed surface area.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent makes multiple surfaces within the suite multi-functional. The seat back, seat bottom, ottoman, armrests, and bed extension can function independently as seating or storage elements, but when combined form a comprehensive bed system. This universality allows the same surfaces to serve multiple purposes, increasing bed surface area without proportionally increasing device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Device complexity

If the bed is formed only from the seat, then the device complexity is minimized, but sleeping comfort deteriorates due to exposed hard surfaces

Engineering Contradiction:
Improvestructure complexityVSAvoidhard surface contact
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent merges the seat surfaces with the ottoman and armrest surfaces to create a comprehensive bed covering. This combination ensures that all hard surfaces are connected and covered by bedding, eliminating exposed hard surfaces that would cause discomfort during sleep while maintaining a coordinated structural approach.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If the bed occupies only part of the floor space, then the suite density is improved, but sleeping comfort deteriorates due to restricted passenger movement

Engineering Contradiction:
Improvesuite densityVSAvoidpassenger movement space
Core Design Contradiction:
ProductivityVSArea of moving object

Solution Approach 1:

The patent employs dynamic, adjustable surfaces that can transition between seating and bed configurations. The seat back, ottoman, and armrests can be positioned at different angles and heights to optimize both suite density during daytime and sleeping comfort during nighttime, allowing the system to adapt to different operational requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the spatial parameters of the suite surfaces by adjusting the seat back angle, ottoman position, and armrest height. These parameter changes enable the same physical surfaces to provide adequate movement space for sleeping comfort while maintaining efficient suite density through optimized geometric arrangements.

Inventive Principle:
Principle #35Parameter changes

4Object-affected harmful factors

If privacy screening is added to enhance sleeping comfort, then passenger privacy is improved, but device complexity increases

Engineering Contradiction:
ImproveprivacyVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent employs a privacy screen that functions as a flexible partition within the suite. This thin film or panel structure provides effective privacy screening without adding substantial structural complexity, as it can be integrated into the existing suite framework and does not require heavy support infrastructure.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

An aircraft passenger suite (10) including a seat (12) configured for movement between an upright position and a horizontal bed position, an ottoman (18) positioned apart from the passenger seat, and at least one armrest assembly (20) configured for vertical movement, wherein the seat, ottoman and at least one armrest reside in horizontal alignment to form a bed in the horizontal bed position.
