Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle display systems, such as those in aircraft, lack the ability to provide an adaptive and dynamic virtual representation of the sky, weather features, and celestial bodies that enhance passenger experience and ambiance.

Innovation Solution

A display system onboard a vehicle, such as an aircraft, utilizes a video processor to render image data based on vehicle status data, including position and altitude, to display an adaptive virtual representation of the sky on a ceiling-mounted display element, which adjusts visual characteristics in real-time with changes in position and altitude.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a display system uses a ceiling-mounted display element to present visual content, then the viewing experience for occupants is improved, but the system lacks adaptability to vehicle status changes and real-time environmental conditions

Engineering Contradiction:

Improveadaptability to vehicle statusVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display system receives vehicle status data from sensors and continuously adjusts the virtual sky representation based on real-time feedback about aircraft position, orientation, and motion. This creates a closed-loop system where the display adapts dynamically to changing vehicle conditions, resolving the contradiction between adaptability and complexity by implementing targeted feedback mechanisms rather than comprehensive system redesign

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system transitions from a static display to a dynamic virtual sky that changes in real-time according to vehicle status. The virtual environment responds dynamically to aircraft movements, creating an immersive experience that adapts to the vehicle's operational state without requiring complex mechanical adjustments to the physical display hardware

Inventive Principle:

Principle #15Dynamics

2Measurement precision

If the display system renders adaptive virtual sky based on position and altitude data, then the realism and immersion of the virtual environment is improved, but the computational processing requirements increase

Engineering Contradiction:

Improveaccuracy of virtual sky representationVSAvoidenergy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system pre-calculates and stores sky representation data for various position and altitude conditions. When the aircraft is in a particular state, the system retrieves and displays the pre-rendered sky data rather than calculating it in real-time, maintaining high accuracy while reducing computational energy consumption during operation

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system adjusts the level of detail and computational intensity of sky rendering based on aircraft parameters such as altitude and speed. At high altitudes where the sky appears more uniform, the system reduces rendering complexity, while at lower altitudes with more atmospheric variation, it increases detail, optimizing energy use relative to the required accuracy

Inventive Principle:

Principle #35Parameter changes

3Illumination intensity

If the display element is integrated into the cabin ceiling, then the ambient lighting and atmosphere are improved, but the display may cause glare or discomfort to passengers

Engineering Contradiction:

Improvecabin ambiance lightingVSAvoidpassenger discomfort from glare

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The virtual sky display dynamically adjusts its color temperature and brightness to match natural sky conditions corresponding to the aircraft's position and time of day. During daytime flights, the display shows brighter blue skies, while during nighttime flights, it displays darker skies with appropriate star patterns, creating natural ambient lighting that avoids glare and passenger discomfort

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The system uses the full three-dimensional viewing space above passengers to create a immersive sky environment, distributing light across a wide area rather than concentrating it in one direction. This dimensional approach to lighting reduces localized glare while maintaining overall ambient illumination that enhances passenger comfort

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
