Solution Overview

Problem

Traditional aircraft seating lacks privacy in economy class and insufficient stowage opportunities for personal items, with premium economy offering these amenities.

Innovation Solution

An aircraft passenger seat assembly featuring a closeout body that fills gaps between seatbacks, incorporating a privacy panel and storage structures like cupholder assemblies, fabricated through thermoforming or injection molding, and coupled using mechanical fasteners or solvent bonding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional economy seating is used, then seat cost is reduced, but privacy between passengers deteriorates

Engineering Contradiction:
Improveseat costVSAvoidprivacy between passengers
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The seat assembly is divided into separate functional modules: a base seat structure and a detachable privacy closeout body. This segmentation allows the privacy feature to be added as a separate component that can be installed on economy seats without redesigning the entire seat assembly, thus maintaining cost-effectiveness while improving privacy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The privacy closeout body is merged with the seatback bezel through coupling mechanisms (mechanical fasteners or solvent bonding) to create an integrated assembly. This merging provides the privacy function while maintaining a unified structure that fits within the existing seat design, avoiding the need for completely separate privacy structures.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If traditional aircraft seating is used, then device complexity is reduced, but stowage opportunities for personal items deteriorate

Engineering Contradiction:
Improveseat structureVSAvoidstowage opportunities
Core Design Contradiction:
Device complexityVSQuantity of substance

Solution Approach 1:

The closeout body serves multiple functions simultaneously: it provides privacy separation between adjacent seats, creates structural support for mounting storage features, and houses cupholder assemblies and other personal item storage opportunities. This multi-functionality adds stowage capacity without requiring entirely separate structural elements.

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

Solution Approach 2:

Storage opportunities are added in the vertical dimension by incorporating cupholder assemblies and storage compartments within the closeout body structure, which extends the functional space beyond the traditional horizontal seat footprint. This allows personal items to be stored in the space between seatbacks without affecting seat functionality.

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

3Object-affected harmful factors

If privacy panels are added to economy seats, then privacy between passengers is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveprivacy between passengersVSAvoidmanufacturing complexity
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The closeout body is pre-formed as a complete integrated component including privacy surfaces and storage features before installation. This preliminary formation of the privacy structure as a single unit simplifies the final assembly process, as the entire privacy module can be installed as one component rather than assembling separate privacy elements during manufacturing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The closeout body acts as an intermediary component between the seatback bezel and the privacy panel. This intermediary structure provides a standardized mounting interface that simplifies the connection between different privacy components, making manufacturing and assembly more straightforward by using the closeout body as a unifying element.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Object-affected harmful factors

If closeout body is coupled to seatback bezel, then privacy separation is improved, but coupling complexity increases

Engineering Contradiction:
Improveprivacy separationVSAvoidcoupling mechanism
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The coupling mechanism is designed to be self-contained within the closeout body structure, using integrated features such as snap-fit connections or pre-applied adhesives that allow the closeout body to be attached to the seatback bezel without requiring complex external fastening systems. The coupling structure serves itself by being incorporated into the design of the closeout body rather than requiring separate coupling components.

Inventive Principle:
Principle #25Self-service

AI summary

An aircraft passenger seat assembly is disclosed. In embodiments, the aircraft passenger seat assembly includes an aircraft passenger seat (101), wherein the aircraft passenger seat includes a seatback (103) configured to support an upper body of an aircraft passenger, and a seatback bezel (105) defining at least a portion of a rear seatback surface. In embodiments, the aircraft passenger seat assembly may further include at least one privacy assembly (102), wherein the at least one privacy assembly includes a closeout body (104) coupled to the seatback bezel, and a privacy panel (106) coupled to the closeout body, the privacy panel extending from the closeout body in order to at least partially separate a seating environment of the aircraft passenger seat from an adjacent seating environment of an adjacent aircraft passenger seat.
