Solution Overview

Problem

Commercial aircraft seating systems often struggle to accommodate passengers with larger sizes, leading to inefficiencies in passenger density and revenue loss due to the need for additional seats, which can be unaffordable or unpopular with passengers.

Innovation Solution

The implementation of a seating system with adjustable dimensions and configurations, including a frame that supports multiple seating systems of different widths, allowing for the accommodation of various passenger sizes without requiring additional seats, thereby optimizing space and passenger comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If standard-width seats are used to maximize passenger density, then more passengers can be seated, but passengers with larger sizes cannot fit comfortably

Engineering Contradiction:
Improvepassenger densityVSAvoidaccommodation of different passenger sizes
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The patent applies the dynamics principle by making the seat width adjustable through movable armrests that can be repositioned along the seat structure. This allows the seat to dynamically change its effective width to accommodate passengers of different sizes, resolving the contradiction between maintaining high passenger density with standard seats and adapting to larger passengers who need more space.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If additional seats are provided for larger passengers, then comfort is improved, but revenue is lost due to unavailable seats for sale

Engineering Contradiction:
Improvepassenger comfortVSAvoidrevenue loss
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

By implementing adjustable-width seats, the patent enables a single seat to dynamically adapt to passengers of different sizes. This eliminates the need to reserve additional seats for larger passengers, as the same seat can be adjusted to fit them comfortably. Consequently, more seats remain available for sale, preventing revenue loss while maintaining passenger comfort.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If fixed-width seats are used, then manufacturing and installation are simplified, but flexibility to accommodate varying passenger needs is reduced

Engineering Contradiction:
Improveseat production simplicityVSAvoidseat configuration flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent introduces adjustable armrests that can be repositioned along the seat structure, transforming fixed-width seats into dynamically adjustable ones. This maintains manufacturing simplicity while adding flexibility, as the adjustment mechanism uses straightforward components that can be integrated into existing seat designs without complex production processes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjustable armrest system enables a single seat design to serve multiple functions by accommodating passengers of various sizes. The seat becomes universal, capable of adapting to different passenger needs without requiring multiple specialized seat types, thus maintaining ease of manufacture while enhancing adaptability.

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