Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional headrests in aircraft seats lack adequate neck support and adjustability, requiring passengers to bring their own neck pillows, which are cumbersome and non-compliant with FAA flammability requirements.

Innovation Solution

An integrated seat assembly with independently adjustable headrest and neck support subassemblies, featuring rotatably connected segments and gooseneck supports, allowing for customizable positioning and integration of additional features like speakers, massagers, and heaters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separate headrest is provided for head support and centering, then head comfort is improved, but neck support is insufficient

Engineering Contradiction:

Improvehead comfortVSAvoidneck support capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent combines the headrest and neck support functions into a single integrated assembly. The headrest includes both a head support portion and a neck support portion that work together, eliminating the need for separate components and providing both head centering and neck support simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The headrest is divided into distinct functional segments: a head support portion for centering the head and a neck support portion for supporting the neck. These segments can be independently adjusted to accommodate different user needs and preferences.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If headrest adjustability is provided for height and tilt, then head support comfort is improved, but neck support adjustability is limited

Engineering Contradiction:

Improvehead support adjustabilityVSAvoidneck support adjustability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The neck support portion incorporates an articulating support with multiple degrees of freedom, allowing dynamic adjustment in addition to the standard height and tilt adjustments. This enables the neck support to adapt to various positions and user preferences.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The articulating support adds a new dimension of adjustability to the neck support portion, enabling movement in multiple directions beyond simple height and tilt adjustments, thereby providing comprehensive neck support coverage.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of operation

If passengers use personal neck pillows for neck support, then neck comfort is improved, but device complexity and compliance issues arise

Engineering Contradiction:

Improveneck comfortVSAvoidcompliance and portability requirements

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates the neck support function directly into the aircraft seat headrest assembly, eliminating the need for passengers to carry separate neck pillows. This unified design ensures FAA compliance and removes the burden of managing additional personal items.

Inventive Principle:

Principle #5Merging (Combining)

4Adaptability or versatility

If an integrated headrest and neck support assembly is provided, then both head and neck support are improved, but device complexity increases

Engineering Contradiction:

Improvehead and neck support capabilityVSAvoidassembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The integrated assembly is divided into modular components including a head support portion, neck support portion, and articulating support mechanisms. This segmentation allows for independent adjustment of each component while maintaining an organized and manageable overall structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The articulating support mechanisms provide dynamic adjustability with multiple degrees of freedom, allowing the neck support portion to move independently from the head support portion. This dynamic capability enhances adaptability without requiring excessive structural complexity.

Inventive Principle:

Principle #15Dynamics
