Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual specification of measurement procedures for radio frequency measurement devices is time-consuming and prone to errors, leading to incomplete or faulty datasets when retrospectively analyzing measurement operations.
Innovation Solution
An automated system that monitors and records operational steps of measurement devices, combining them with measurement data to generate a metadata package, allowing for retrospective analysis without additional user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual specification of measurement procedures is used, then users can provide measurement results and configuration information, but the process becomes time-consuming and error-prone
Solution Approach 1:
The measurement device automatically monitors its own operational steps and generates the metadata package without requiring user intervention. The device serves itself by capturing its operational data, thereby eliminating the time-consuming manual specification process while ensuring complete and accurate recording of all measurement procedures
Solution Approach 2:
A monitoring device acts as an intermediary between the measurement device and the user. This intermediary automatically captures operational steps and generates the metadata package, removing the burden from the user while ensuring accurate and complete documentation of the measurement process
2Loss of information
If manual specification of measurement procedures is used, then users can provide measurement information, but the information may be incomplete or faulty due to user memory limitations
Solution Approach 1:
The measurement device automatically monitors and records all its operational steps, ensuring that no information is lost or forgotten. The device independently captures complete measurement procedure data without relying on user memory, thereby maintaining information completeness while simplifying the user's task to merely initiating and reviewing the measurement
Solution Approach 2:
The monitoring device serves as an intermediary that objectively records all operational steps between the user's actions and the final dataset. This intermediary ensures complete and accurate information capture without being affected by user memory limitations or errors, while keeping the user interface simple and easy to operate
3Reliability
If automated monitoring of operational steps is implemented, then complete measurement related data is captured, but system complexity increases
Solution Approach 1:
The monitoring functionality is merged with the existing measurement device, either as an integrated component or closely coupled subsystem. This merging approach ensures complete data capture while avoiding the need for entirely separate complex systems, as the monitoring leverages the device's existing operational data structures and interfaces
Solution Approach 2:
The measurement device is designed to serve multiple functions: performing the actual measurement and simultaneously monitoring its own operational steps. This multi-functionality reduces overall system complexity by eliminating the need for separate dedicated monitoring equipment, while still ensuring complete and reliable data capture
Data Source
AI summary
The present invention relates to a data acquisition of measurement data together with further data specifying the operation during a measurement. For this purpose, I/Q measurement data are obtained and the steps for operating a measurement device during the measurement are monitored. A metadata package is generated, which includes the obtained I/Q measurement data along with the monitored steps of operating the measurement device.
