Seat-Integrated Projection Device for Flexible Aircraft Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft seat displays are inflexible, requiring fixed installations that complicate reconfiguration and maintenance, especially in changing seat arrangements, and do not adapt well to passenger needs or safety directives.
Innovation Solution
Integration of an image projection device within a seat element that projects image elements onto a flexible imaging region, allowing for variable positioning and adjustment of display information, including safety warnings and passenger-specific content, using a control unit to maintain image quality and focus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed display elements are installed in aircraft seats, then information can be displayed to passengers, but the system becomes inflexible and difficult to reconfigure when seat arrangements change
Solution Approach 1:
The patent applies the dynamics principle by replacing fixed display elements with a projection device that can dynamically adjust the position and orientation of the imaging region. The projection device projects images onto a flexible screen that can be positioned at various locations relative to the seat, allowing the display system to adapt when seat arrangements change without requiring physical reinstallation of displays.
Solution Approach 2:
The projection device serves multiple functions: it can display various types of information (safety warnings, seat numbers, passenger-specific content), adjust to different seating configurations, and accommodate changes in seat positions. This multi-functionality resolves the contradiction by making a single device adaptable to multiple display scenarios rather than requiring dedicated fixed displays for each function.
2Reliability
If fixed display elements are installed in aircraft seats, then information can be displayed to passengers, but reconfiguration time increases when seat arrangements need to change
Solution Approach 1:
The dynamic projection system eliminates reconfiguration time by allowing the imaging region to be repositioned electronically rather than requiring physical movement or reinstallation of fixed displays. When seat arrangements change, the projection device can instantly adjust the display position to maintain proper alignment with passengers.
3Reliability
If fixed display elements are installed in aircraft seats, then information can be displayed to passengers, but the system complexity increases due to permanent installations
Solution Approach 1:
The patent extracts the display function from fixed installations and consolidates it into a movable projection device integrated with the seat. This removes the complexity of permanent mounting structures, wiring, and alignment requirements associated with fixed displays, while maintaining the essential function of providing reliable information to passengers.
