Solution Overview

Problem

The cumbersome and error-prone process of cabling devices under test (DUT) to test equipment, leading to increased testing time and diminished performance due to the need for re-cabling in different test scenarios, is addressed by providing a method and system for automatically deriving an optimal connection diagram based on a Band-Centric DUT connector configuration.

Innovation Solution

A method and system that automatically calculate a connection diagram between a test device and a DUT using a Band-Centric DUT Connector Configuration, employing optimization algorithms like MILP and reinforcement learning to minimize re-cabling, and a Connection Diagram Rating Engine to select the optimal diagram.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual cabling is performed for each test scenario, then the device under test can be connected to the test equipment, but the testing time increases and testing performance diminishes due to repeated re-cabling

Engineering Contradiction:
Improvetesting performanceVSAvoidtesting time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system pre-calculates and stores optimal connection diagrams for different test scenarios before actual testing begins. The Band-Centric DUT Connector Configuration is established in advance, and the automatic calculation system prepares connection recommendations for multiple potential test scenarios, so that when a test scenario is selected, the cabling configuration is already determined and ready for immediate implementation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates a virtual representation (connection diagram) of the physical cabling configuration. Instead of manually configuring physical connections for each test scenario, the system generates digital connection diagrams that replicate the required cable assignments, allowing operators to select and implement configurations through software rather than physically re-cabling for each test.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If manual cabling configuration is used, then flexibility to handle different test scenarios is achieved, but the process becomes cumbersome and error-prone

Engineering Contradiction:
Improveflexibility for different test scenariosVSAvoidcabling process complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs automatic calculation and selection of connection diagrams without requiring manual intervention. The Band-Centric DUT Connector Configuration automatically feeds into the calculation engine, which generates optimal connection recommendations based on the selected test scenario. The system serves itself by determining the appropriate cabling configuration without operator input, reducing both complexity and potential for human error.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system replaces the mechanical process of manual cable configuration with an automated computational system. Instead of operators physically manipulating cables and connectors based on manual procedures, the system uses automatic calculation algorithms to determine optimal connections and presents them through a user interface, substituting mechanical cabling operations with digital computation and display.

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

3Reliability

If the connection diagram calculation system is extended for every new DUT, then accurate connection recommendations can be provided, but the system complexity increases

Engineering Contradiction:
Improveconnection diagram accuracyVSAvoidsystem extension requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system uses a universal Band-Centric DUT Connector Configuration that can be applied across different device types. Rather than creating entirely new configuration systems for each DUT model, the same core configuration structure serves multiple devices, with the automatic calculation engine adapting the universal configuration to specific test scenarios. This multi-functional approach maintains accuracy while avoiding the need to extend the system for every new DUT.

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