Aircraft Floor Projection Device for Passenger Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircrafts face challenges in providing convenient services to passengers due to limited crew members and difficulty in recognizing seat positions, especially in night lighting mode when passengers are sleeping, making it hard for passengers to communicate their needs.
Innovation Solution
An aircraft projection device that projects images onto the floor surface, using sensors to control the projection based on detection information such as seating and illuminance, allowing passengers to recognize seat numbers and communicate needs visually, with the projector discreetly positioned inside seats and illuminance sensors managing projection timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If interior lights are dimmed to night lighting mode for passenger comfort, then passenger comfort is improved, but passenger ability to recognize seat position and communicate needs deteriorates
Solution Approach 1:
The patent introduces a new spatial dimension for information display by projecting seat identification and communication messages onto the floor surface, rather than relying solely on ceiling-mounted display panels. This allows passengers to view information while keeping their heads in natural positions and enables communication without disturbing other passengers in seated positions.
Solution Approach 2:
The projection system acts as an intermediary between the passenger and the aircraft systems. Instead of passengers directly interacting with overhead panels or crew members, the system uses projected images on the floor as a mediator to convey seat position information and passenger requests to the crew.
2Ease of operation
If more crew members are added to improve passenger service, then passenger service quality is improved, but operational cost and complexity increase
Solution Approach 1:
The system enables passengers to independently communicate their needs and seat position information through the projection interface. Passengers can indicate their seat number and requests (such as needing assistance) by interacting with the projected display on the floor, reducing the need for crew members to continuously monitor and assist each passenger.
Solution Approach 2:
The system provides visual feedback to passengers through the projected images, confirming their seat position and the status of their requests. This feedback mechanism allows passengers to verify information without crew intervention and enables crew members to respond more efficiently to confirmed passenger needs.
3Loss of information
If traditional ceiling-mounted display panels are used for seat identification, then information display is achieved, but passenger visibility and comfort are reduced due to head position constraints
Solution Approach 1:
The patent transitions from vertical display (ceiling panels requiring upward head movement) to horizontal display (floor projection allowing natural head position). This dimensional change in information presentation enables passengers to view seat identification and communication interfaces without altering their head or body position.
