Solution Overview

Problem

Current in-flight entertainment systems and passenger seat designs lack effective solutions for enhancing privacy and entertainment options, particularly in terms of variable transparency and flexible use of surfaces for content viewing.

Innovation Solution

A variable transparency panel using electrochromatic or smart glass technology that can transition from transparent to opaque or non-translucent states upon voltage application, allowing for enhanced privacy and flexible use as a viewing screen, secured to various surfaces such as seatbacks or armrests, and controlled by individual or master controllers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If individual IFE units are provided at each seat, then entertainment functionality is improved, but cost and device complexity increase

Engineering Contradiction:
Improveentertainment functionalityVSAvoidcost and device complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by making the transparent panel serve multiple functions: it acts as both a privacy divider and an entertainment display surface. The same panel that provides physical separation between passengers can also function as a screen for video content, eliminating the need for separate IFE units at each seat.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the privacy partition function with the entertainment display function into a single integrated system. The transparent panel combines the roles of a physical divider and a video screen, reducing overall system complexity and cost.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If heavy screens are used for entertainment displays, then display functionality is improved, but safety concerns arise

Engineering Contradiction:
Improvedisplay functionalityVSAvoidsafety concerns
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses a transparent panel that is thin and lightweight rather than heavy screens. This thin-film approach maintains display functionality while eliminating safety hazards associated with heavy, breakable screen materials in aircraft seating environments.

Inventive Principle:
Principle #30Flexible shells and thin films

3Object-affected harmful factors

If physical dividers are used for privacy, then privacy protection is improved, but sense of spaciousness deteriorates

Engineering Contradiction:
Improveprivacy protectionVSAvoidsense of spaciousness
Core Design Contradiction:
Object-affected harmful factorsVSArea of stationary object

Solution Approach 1:

The patent uses electrochromic technology that allows the panel to change its optical properties. When transparent, the panel provides privacy while maintaining visual continuity and sense of space. When opaque, it provides enhanced privacy when needed, allowing the system to balance both requirements dynamically.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent applies dynamics by making the privacy panel's transparency variable rather than fixed. The electrochromic panel can dynamically switch between transparent and opaque states, providing privacy when needed while maintaining openness and spaciousness at other times.

Inventive Principle:
Principle #15Dynamics

4Area of stationary object

If transparent panels are used, then sense of spaciousness is improved, but privacy protection deteriorates

Engineering Contradiction:
Improvesense of spaciousnessVSAvoidprivacy protection
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent resolves this contradiction by making the panel's transparency dynamic rather than static. The electrochromic technology allows the same panel to switch between transparent (spacious) and opaque (private) states based on operational requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent makes the transparent panel multi-functional by enabling it to serve both as a privacy divider and an entertainment display. The panel's ability to function in multiple modes (transparent for space, opaque for privacy, and display surface for entertainment) resolves the trade-off between spaciousness and privacy protection.

Inventive Principle:
Principle #6Universality (Multi-functionality)
