Solution Overview

Problem

The management and updating of warning messages in aircraft flight warning systems become cumbersome due to the varied configurations of monitored systems across different aircraft, leading to a high workload and cost in maintaining multiple sets of documentation.

Innovation Solution

A method and system for updating warning messages by delivering modification information items to a selection tool, which selects the appropriate content based on the aircraft's configuration, allowing for a single set of information items to be used across multiple aircraft models, reducing the need for multiple documentation sets and simplifying the update process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple sets of portable documentation are maintained for different aircraft configurations, then the warning message content can be adapted to each specific configuration, but the workload and cost of management and updating increase significantly

Engineering Contradiction:

Improveadaptability of warning message content to different aircraft configurationsVSAvoidcomplexity of managing multiple documentation sets

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal database structure that stores warning message content applicable to multiple aircraft configurations. Instead of maintaining separate documentation sets for each configuration, a single database contains configuration-specific fields that allow the same base message to be adapted to different aircraft types, configurations, and even individual aircraft identifiers. This universal approach eliminates the need for multiple separate documentation sets while maintaining the ability to provide configuration-specific information.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The warning message content is segmented into configurable fields that can be individually customized based on aircraft configuration. The message template includes placeholders and parameters that are populated dynamically based on the specific aircraft's configuration data. This segmentation allows the system to maintain a single documentation set while providing tailored information for each aircraft configuration through parameterized content.

Inventive Principle:

Principle #1Segmentation

2Productivity

If a single set of documentation is used for all aircraft configurations, then the management and updating workload is reduced, but the ability to provide configuration-specific information is lost

Engineering Contradiction:

Improveefficiency of documentation management and updatingVSAvoidloss of configuration-specific information

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The documentation system is made dynamic through parameterized fields that automatically adapt to different aircraft configurations. The database structure includes configurable parameters that are populated based on the specific aircraft's configuration data, allowing the same documentation template to dynamically provide configuration-specific information. This dynamic approach enables a single documentation set to serve multiple configurations without information loss.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces a configuration data structure as an intermediary between the single documentation set and the various aircraft configurations. This intermediary layer contains aircraft-specific parameters and identifiers that mediate between the universal documentation template and the specific configuration requirements, enabling the system to maintain a single documentation set while preserving configuration-specific information through the intermediary data structure.

Inventive Principle:

Principle #24Intermediary (Mediator)
