Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current AI and machine learning models for test and measurement systems require extensive data gathering, training, and validation processes that are time-consuming, disrupting the user's workflow and affecting the testing cycle.
Innovation Solution
An AI assistant that autonomously interprets complex data patterns and performs predictive maintenance by training in real-time as users operate the test and measurement instrument, allowing for consistent model deployment across multiple endpoints without altering the user's workflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-trained machine learning models are used for data analysis and predictive maintenance, then prediction accuracy is improved, but the training and validation process takes excessive time, disrupting user workflow
Solution Approach 1:
The system performs preliminary data gathering and model training during instrument operation and idle periods, so that when predictive maintenance is needed, the model is already trained and ready to provide immediate predictions without disrupting the user workflow
Solution Approach 2:
The machine learning model is designed to be dynamically trainable, allowing it to continue learning from new data during instrument operation. This enables the model to improve its accuracy over time without requiring complete retraining, thus reducing the time needed for updates while maintaining high prediction accuracy
2Reliability
If extensive data gathering and model training are performed to improve predictive maintenance capabilities, then prediction reliability is improved, but the testing cycle duration increases
Solution Approach 1:
The system performs data gathering and model training continuously during instrument operation rather than requiring separate dedicated training phases. This allows the predictive maintenance model to be developed and refined without interrupting the normal testing cycle, maintaining both reliability and efficiency
Solution Approach 2:
The machine learning model trains itself automatically using data collected during normal instrument operation. This self-service capability eliminates the need for manual intervention in the training process and allows the model to improve predictive maintenance reliability without extending the testing cycle

AI summary
A test and measurement instrument includes one or more ports to connect to a device under test (DUT), a user interface having one or more controls, a display, a storage, one or more processors to receive test signals from the DUT through the one or more ports as test of the DUT, use the test signals to generate test data, display test data on the display, display a control button on the user interface indicating that an artificial intelligence (AI) assistant is available, receive an input through the control button to start the AI assistant, provide regions on the user interface to allow the user to interact with the AI assistant, and apply a machine learning model represented by the AI assistant to provide the user with additional information related to one or more of the test and the DUT.
