Solution Overview

Problem

Manually adjusting the positions and configurations of aircraft passenger service units in response to seat configuration changes within a passenger cabin is cumbersome and time-consuming.

Innovation Solution

Implementing near field communication interfaces in aircraft passenger service units to enable automated determination of spatial positions and orientations, allowing for automated reconfiguration of the units based on wireless communication between neighboring units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual adjustment of passenger service unit positions is used, then configuration flexibility is maintained, but installation time and operational complexity increase significantly

Engineering Contradiction:

Improveinstallation speedVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The passenger service units automatically determine their own spatial positions and orientations by exchanging messages with neighboring units through near field communication interfaces. This self-configuration capability eliminates the need for manual adjustment, significantly reducing installation time and operational complexity while maintaining configuration flexibility

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical adjustment with an automated electronic communication system. Near field communication interfaces enable wireless exchange of position and orientation data between units, substituting the mechanical manual repositioning process with an automated digital system that determines configurations based on exchanged messages

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Loss of time

If automated reconfiguration systems are implemented, then installation time is reduced, but device complexity and communication requirements increase

Engineering Contradiction:

Improveconfiguration timeVSAvoidcommunication interface complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The automated reconfiguration system is divided into independent near field communication interfaces located at different end portions of each passenger service unit. Each interface communicates only with neighboring units, segmenting the complex communication task into manageable local interactions that reduce overall system complexity while enabling automated configuration

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The near field communication interfaces act as intermediaries that automatically exchange position and orientation information between neighboring passenger service units. This intermediary communication mechanism eliminates the need for manual intervention, reducing configuration time while managing complexity through standardized message exchange protocols

Inventive Principle:

Principle #24Intermediary (Mediator)
