Solution Overview

Problem

Head-up displays (HUDs) often suffer from degraded image quality in certain lighting conditions, making it difficult to view detailed information, and information is more easily viewed on head-down displays (HDDs) rather than HUDs due to clutter from symbols and images.

Innovation Solution

A display system that includes a processor, projector, and combiner configured to provide conformally mapped images, allowing transparent windows on the HUD for viewing HDD information without interference, enabling seamless integration of HUD and HDD data through user gestures and spatial registry software.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If HUD displays information conformally with the environment view, then visual range is enhanced, but image quality degrades in certain lighting conditions making detailed information difficult to view

Engineering Contradiction:
Improveimage qualityVSAvoidviewing capability in different lighting conditions
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The display system is segmented into two distinct parts: a HUD combiner for displaying conformal flight information and a separate HDD (head-down display) for displaying detailed information. This segmentation allows each display type to optimize for its specific function, with the HDD providing high-quality detailed views without compromising the HUD's conformal display capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A transparent window is introduced as an intermediary element on the HUD combiner. This window allows the pilot to view HDD information through the HUD display without the HDD physically obstructing the view. The transparent window acts as a mediator that integrates both display systems while maintaining image quality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If HUD displays conformal symbols and images, then spatial awareness is improved, but information clutter makes it difficult to view detailed information

Engineering Contradiction:
Improveinformation visibilityVSAvoiddisplay clutter
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

Information is segmented and distributed across two displays: the HUD combiner displays conformal symbols and images for spatial awareness, while the HDD displays detailed information such as lists and text. This segmentation eliminates information clutter on the HUD while maintaining spatial awareness benefits.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Detailed information that would clutter the HUD display is extracted and moved to the separate HDD. The transparent window on the HUD allows access to this extracted information without adding visual clutter to the conformal display.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If separate HDD and HUD displays are used, then information viewing capability is improved, but system complexity increases

Engineering Contradiction:
Improveinformation viewingVSAvoiddisplay system integration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The HUD and HDD systems are merged through the transparent window integration on the combiner. This allows both displays to work together as a unified system, improving ease of operation by allowing pilots to access HDD information through the HUD without requiring separate viewing actions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The combiner serves multiple functions: it displays conformal HUD information and simultaneously provides a transparent window for viewing HDD information. This multi-functionality reduces overall system complexity by making the combiner a universal interface for both display types.

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