Solution Overview

Problem

Manually adjusting aircraft passenger service units to accommodate changes in seat configurations within an aircraft cabin is cumbersome and time-consuming, requiring significant effort and disrupting the efficient provision of services to passengers.

Innovation Solution

Incorporating a seat detection sensor that automatically determines the position and orientation of passenger seats relative to the service units, allowing for autonomous adjustment of the service unit configurations, including reading lights, air gaspers, and oxygen masks, thereby eliminating the need for manual intervention during seat configuration changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adjustment of passenger service units is used to accommodate seat configuration changes, then the service units can be positioned correctly relative to passenger seats, but the process becomes cumbersome and time-consuming

Engineering Contradiction:
Improveease of adjusting service unit positionsVSAvoidtime required for seat configuration changes
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The passenger service unit automatically detects seat positions using sensors (optical, acoustic, electromagnetic) and self-adjusts its operational parameters including reading light directions, air gasper positions, and oxygen mask deployments without requiring manual intervention. This self-service capability eliminates the time-consuming manual adjustment process while ensuring correct positioning relative to passenger seats

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical adjustment with automated detection and control systems. Sensors detect seat positions and configurations, and actuators automatically adjust service unit components (lights, gaspers, masks) based on detected parameters, substituting the manual mechanical adjustment process with an automated sensor-actuator system

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If the seat configuration is changed to meet diverse passenger needs, then passenger comfort and service quality improve, but the manual reconfiguration process becomes more complex and time-consuming

Engineering Contradiction:
Improveability to change seat configurationsVSAvoidspeed of reconfiguration
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system continuously monitors seat positions and configurations using sensors, and automatically adjusts service unit parameters based on real-time feedback. This feedback loop enables rapid adaptation to different seat configurations (individual seating, group seating, mixed configurations) without manual intervention, maintaining high productivity during reconfiguration

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The passenger service unit is designed with dynamic adjustment capabilities where components such as reading lights, air gaspers, and oxygen masks can automatically change their positions and operational states based on detected seat configurations, enabling rapid adaptation to various seating arrangements

Inventive Principle:
Principle #15Dynamics
