Solution Overview

Problem

Existing aircraft vertical speed indicators (VSIs) lack the capability to provide additional critical flight information without requiring instrument panel modifications or replacing critical instruments, limiting their functionality and safety implications in case of failure.

Innovation Solution

A computerized VSI with an electronic display, such as an LCD, is designed to fit within the standard VSI form factor, offering enhanced functionality by displaying vertical speed, altitude, maps, navigation, terrain, and other data, while retaining the mechanical aspects of traditional VSIs, including a dog-leg portion for user interface, and incorporating ambient light sensing for adjustable brightness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional VSI instrument is used, then instrument panel modification is avoided, but additional flight information cannot be provided

Engineering Contradiction:

Improveadditional flight information capabilityVSAvoidinstrument functionality

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies multi-functionality by integrating multiple flight information display capabilities (vertical speed, altitude, maps, navigation, terrain, traffic, engine data, performance data, fuel data) into a single VSI instrument housing. This allows one instrument to serve multiple functions, providing enhanced versatility without requiring separate instruments or panel modifications.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses an electronic display (LCD) that visually replicates traditional VSI information while adding enhanced capabilities. The display copies the essential VSI function of showing vertical speed but enhances it with additional graphical and textual flight information, effectively creating a modernized version of the traditional instrument.

Inventive Principle:

Principle #26Copying

2Adaptability or versatility

If instrument panel modification is performed, then additional information can be displayed, but critical instruments may be replaced or panel layout altered

Engineering Contradiction:

Improveinformation display capabilityVSAvoidcritical instrument preservation

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

By making the VSI instrument multi-functional, the patent allows it to provide additional information without requiring replacement of critical instruments. The enhanced VSI serves multiple purposes including vertical speed indication, altitude display, and various navigation and monitoring functions, thereby preserving the reliability and criticality of existing instruments while adding capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of manufacture

If standard VSI form factor is maintained, then instrument panel installation is simplified, but functionality is limited

Engineering Contradiction:

Improveinstrument panel installationVSAvoidfunctionality

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent maintains the standard VSI form factor and mounting interface while integrating multiple functions into this existing housing. This approach preserves ease of installation and compatibility with standard instrument panels while dramatically enhancing functionality through electronic display capabilities that provide vertical speed, altitude, maps, navigation, terrain, traffic, engine data, performance data, and fuel information.
