Solution Overview

Problem

Current dimmable window systems in commercial aircraft lack interactive features, allowing only full shading or full transparency, failing to provide passengers with the ability to selectively dim specific portions of the window for localized viewing without flooding the cabin with light.

Innovation Solution

An interactive dimmable window system featuring a touchscreen-enabled passenger interface that allows users to control an electronic shade, creating clear apertures in shaded areas through gestures and automatically closing them after a set time, while also displaying information and ambiance adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a dimmable window panel is used to control light entering the cabin, then the amount of light can be reduced, but the entire window panel must be shaded and no localized viewing is possible

Engineering Contradiction:
Improveamount of light entering cabinVSAvoidlocalized viewing capability
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The window panel is divided into multiple independently controllable segments or zones. Each segment can be shaded or cleared individually through separate control elements on the passenger interface, allowing passengers to shade specific portions while maintaining visibility through others. This segmentation enables localized viewing without requiring the entire window to be shaded.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the window panel are given different optical properties independently. Through the touchscreen interface, passengers can apply shading to specific local areas while leaving other areas transparent. This creates non-uniform light transmission across the window surface, allowing simultaneous privacy in some zones and viewing in others.

Inventive Principle:
Principle #3Local quality

2Illumination intensity

If mechanical shades are used to block light, then light control is achieved, but the system is complex and lacks interactive features

Engineering Contradiction:
Improvelight blocking capabilityVSAvoidmechanical shade mechanism
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The traditional mechanical shade system is replaced with an electronic dimming system integrated into the window panel. The touchscreen passenger interface sends electrical signals to control the dimming of specific window segments, eliminating the need for mechanical moving parts. This substitution reduces mechanical complexity while enabling more sophisticated interactive control capabilities.

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

3Illumination intensity

If the entire window panel is shaded to reduce cabin light, then light control is achieved, but passengers cannot view outside environments

Engineering Contradiction:
Improvecabin light levelVSAvoidviewing convenience
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The window is divided into controllable segments that can be independently shaded. Passengers can shade only the portions of the window that are not needed for viewing, while leaving other segments clear. This selective shading maintains optimal cabin light levels while preserving viewing capability through unshaded segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The window shading state is made dynamically adjustable by passengers through the touchscreen interface. Rather than a fixed shaded or clear state, passengers can continuously adjust which portions are shaded and to what degree, allowing real-time optimization between cabin light reduction and viewing convenience based on changing conditions.

Inventive Principle:
Principle #15Dynamics
