Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple different probes and measuring systems are used to account for dynamically changing device characteristics, then measurement accuracy is improved, but measurement time and operational complexity increase
Solution Approach 1:
The patent implements a signal correction filter with dynamically adjustable parameters that can adapt to changing device characteristics during measurement. The filter parameters are modified based on detected signal events, allowing a single probe to effectively handle multiple operating modes without requiring physical probe changes or multiple measurement systems.
Solution Approach 2:
The invention changes the parameters of the signal correction filter dynamically during measurement. When an event is detected in the signal (indicating a mode change), the filter parameters are adjusted to match the new operating conditions, enabling accurate measurement across different device states using the same hardware setup.
2Measurement precision
If multiple different probes and measuring systems are used to account for dynamically changing device characteristics, then measurement accuracy is improved, but device complexity and effort increase
Solution Approach 1:
The patent makes a single signal correction filter capable of performing multiple functions by dynamically adjusting its parameters. Instead of requiring separate probes and measurement systems for different operating modes, the universal filter adapts its characteristics to handle various signal types and device states, simplifying the overall measurement system architecture.
Solution Approach 2:
The filter transitions from a static, fixed-parameter component to a dynamic, adaptive component that automatically adjusts its characteristics based on real-time signal analysis. This dynamic capability eliminates the need for complex multi-probe setups and manual reconfiguration, reducing both device complexity and operational effort.
3Adaptability or versatility
If multiple sequential measurements are performed with different corrections, then adaptability to different operation modes is improved, but error risk increases
Solution Approach 1:
The patent maintains continuous, uninterrupted measurement by dynamically adjusting filter parameters during the measurement process. Instead of stopping to perform separate measurements with different corrections, the system continuously adapts the filter to match current device characteristics, eliminating gaps and reducing opportunities for errors.
Solution Approach 2:
The system implements feedback by monitoring the signal for events that indicate mode changes and automatically adjusting filter parameters in response. This closed-loop approach ensures the measurement system remains adapted to current conditions without manual intervention, reducing errors associated with manual reconfiguration and ensuring consistent measurement quality.
