Solution Overview

Problem

Current laser eye protection solutions for aircraft cockpits are either cumbersome or do not address the need for increased display area, failing to provide effective protection against high intensity light sources while enhancing situational awareness.

Innovation Solution

A transparent display system that incorporates an optical element to reflect, deflect, or absorb high intensity light sources, while also serving as a display surface for presenting information, utilizing technologies like AMLCD, OLED, or projection displays, and can be integrated into aircraft windows for space-efficient cockpit use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If traditional laser eye protection devices are used, then eye protection is provided, but device complexity and ease of operation deteriorate due to cumbersome extendable/retractable mechanisms or requirement for user wearing

Engineering Contradiction:
Improvelaser eye protectionVSAvoidprotective device structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent combines laser protection functionality with the transparent display structure itself, integrating the optical element into the display assembly rather than using separate protective devices. This merging eliminates the need for extendable/retractable mechanisms or user-worn components, resolving the contradiction between protection effectiveness and device complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transparent display serves multiple functions simultaneously: it provides laser eye protection, displays information, and maintains situational awareness. By making the display structure itself multi-functional, the patent eliminates the need for separate protective devices, thereby reducing device complexity while maintaining protection effectiveness

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

2Object-affected harmful factors

If traditional laser eye protection devices are used, then eye protection is provided, but ease of operation worsens due to requiring user action to deploy or wear the devices

Engineering Contradiction:
Improvelaser eye protectionVSAvoidprotective device usage
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

By merging laser protection into the fixed transparent display structure, the system eliminates the need for user actions to deploy or wear protective devices. The protection is automatically active whenever the display is present, resolving the contradiction between protection effectiveness and ease of operation

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transparent display structure provides laser protection automatically without requiring user intervention. The optical element integrated into the display self-services the protection function, eliminating the need for users to manually deploy or wear separate protective devices

Inventive Principle:
Principle #25Self-service

3Area of stationary object

If additional display area is added to cockpit windows, then situational awareness improves, but laser eye protection capability worsens due to increased light transmission

Engineering Contradiction:
Improvedisplay areaVSAvoidlaser exposure risk
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The optical element introduces local quality variations across the display area by selectively filtering specific laser wavelengths while transmitting other light. This allows the display to maintain large area for situational awareness while providing localized wavelength-specific protection against laser threats

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses composite optical structures combining transparent display materials with laser-resistant optical elements. This composite approach enables the display to simultaneously achieve large area transparency for situational awareness and selective laser wavelength blocking for eye protection

Inventive Principle:
Principle #40Composite materials

4Object-affected harmful factors

If transparent display with optical element is implemented, then laser protection and display area are improved, but manufacturing precision requirements worsen due to integration of multiple functional layers

Engineering Contradiction:
Improvelaser eye protectionVSAvoidoptical element integration
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

By designing the optical element to perform multiple functions (laser protection, display transparency, structural integration), the patent reduces the number of separate components requiring precision alignment. The multi-functional design consolidates manufacturing requirements into a single integrated element

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

AI summary

A transparent display provides eye protection from lasers and other high intensity light sources. The transparent display allows users to view objects clearly through the display while also presenting text, graphics or video on the display surface. Simultaneously, the display assembly comprises a component that provides eye protection against high power radiation sources. The transparent display with eye protection provides both protection from high power light sources and an additional cockpit display surface for presentation of information including graphical images, symbology, video, text, and other data.
