Solution Overview

Problem

Current datalink testing for aircraft communications radio suites is labor-intensive and inefficient, often requiring manual testing with insufficient data points, leading to latent issues and schedule and budget impacts due to the need for extensive retesting.

Innovation Solution

An automated close-loop electromagnetic (EM) datalink testing method and system that routes user input data and control commands through a controller and encryption device, encrypts and transmits data via EM signals, and decrypts and processes received data to generate status reports, reducing the need for manual testing and enabling comprehensive data collection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual testing is performed with limited data points, then testing time and resources are reduced, but testing completeness and reliability are insufficient

Engineering Contradiction:
Improvetesting completenessVSAvoidtesting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The automated testing system performs self-service by automatically generating test cases, executing tests, collecting results, and generating reports without continuous human intervention. The system autonomously routes user input data through encryption devices and radios, processes received data, and compares results to identify issues, enabling comprehensive testing with abundant data points while reducing manual labor time.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical testing operations with automated electronic systems. The automated testing system uses software-controlled routing of test data through encryption devices and radios, substituting human operators with automated controllers that can execute thousands of test cases efficiently and consistently, thereby improving testing completeness without proportionally increasing testing time.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If extensive manual testing and retesting is performed, then software integrity is improved, but schedule and budget are negatively impacted

Engineering Contradiction:

Solution Approach 1:

The automated testing system implements feedback mechanisms by automatically comparing received user input data with expected results, identifying discrepancies, and generating status reports. This continuous feedback loop enables rapid detection of software issues and verification of fixes without manual intervention, improving software integrity while maintaining high testing efficiency through automated result analysis and reporting.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables continuous testing operations by automatically routing test data through the complete workflow including encryption devices and radios without interruption. The automated controller continuously executes test cases, processes results, and generates reports, eliminating the discontinuous nature of manual testing where operators must repeatedly set up and configure test environments, thereby improving both software integrity and testing efficiency.

Inventive Principle:
Principle #20Continuity of useful action

3Reliability

If manual testing with insufficient data points is used, then initial testing speed is faster, but latent issues remain undetected

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The automated testing system performs multiple functions through a single integrated platform: generating test cases, routing data through encryption devices and radios, collecting results, analyzing discrepancies, and generating comprehensive reports. This multi-functional system can handle diverse test scenarios and data types uniformly, enabling detection of latent issues across various software components without requiring separate complex testing setups for each function.

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

Solution Approach 2:

The automated controller serves as an intermediary that coordinates between user input, encryption devices, radios, and result analysis. This intermediary component manages the complex routing and processing of test data, abstracting the complexity from the user while enabling comprehensive issue detection. The intermediary automatically handles data transformation and routing through multiple system components, making the complex testing process transparent and manageable.

Inventive Principle:
Principle #24Intermediary (Mediator)
