Solution Overview

Problem

Conventional aircraft passenger seats inadequately provide 'living space' when seating is tight, as pocket-like receptacles underneath the tray table in the knee area restrict leg and knee space, especially when filled with travel items.

Innovation Solution

A pocket-like receptacle is integrated into the unused internal cavity of the backrest support structure, allowing for increased space by relocating storage from the knee area to the backrest, with features like a latch for tray table fixation, a slot-like opening for easy access, and reinforcement to prevent items from slipping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If pocket-like receptacles are mounted underneath the tray table in the knee area, then storage function is provided, but leg and knee space is restricted

Engineering Contradiction:
Improvestorage capacityVSAvoidleg and knee space
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The receptacle is relocated from the horizontal knee area to the vertical backrest support structure, utilizing the unused internal cavity space in the longitudinal dimension of the backrest. This dimensional shift allows storage function to be maintained while freeing up the knee area for passenger leg space.

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

Solution Approach 2:

The receptacle is extracted from its conventional location underneath the tray table and repositioned into the unused internal cavity of the backrest support structure. This extraction removes the space-consuming element from the knee area while preserving its storage functionality in a different location.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If seating is arranged tightly in the cabin interior, then space utilization is improved, but passenger living space is reduced

Engineering Contradiction:
Improvespace utilizationVSAvoidpassenger living space
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The receptacle utilizes the vertical and longitudinal space within the backrest support structure rather than occupying horizontal knee area. This allows tighter seating arrangements in the cabin while maintaining adequate legroom and living space for passengers.

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

Solution Approach 2:

The internal cavity of the backrest support structure, which is normally unused space, is converted into functional storage space. This local utilization of otherwise wasted space enables tighter seating configurations without compromising passenger comfort.

Inventive Principle:
Principle #3Local quality

3Area of stationary object

If receptacle is formed using unused internal cavity of backrest support structure, then legroom is increased, but structural complexity increases

Engineering Contradiction:
ImprovelegroomVSAvoidstructural complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The receptacle is integrated directly into the backrest support structure, merging the storage function with the existing structural framework. This eliminates the need for separate mounting brackets or additional structural elements, thereby increasing legroom without proportionally increasing overall structural complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The backrest support structure serves dual functions: providing structural support for the backrest and housing the receptacle for storage. This multi-functionality allows the same structural elements to serve multiple purposes, increasing legroom availability while minimizing additional structural complexity.

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

AI summary

An aircraft passenger seat with seat components, such as a seating piece and a backrest (1) includes a back support structure (11) supporting a backrest cushion (13). On the back face of the support structure a food table may be folded against the same and extended into an in-use position. A pocket-like container (15), for housing useful objects, such as printed products (17) and traveling utensils 15 is arranged on the support structure. The container (15) is formed by a cavity, extending in the support structure (11) of the backrest (1), at least partly between the folded food table (3) and the backrest cushion (13).
