Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an external arbitrary waveform generator is used to generate output signals for testing devices under test, then the functionality and flexibility of the measurement setup is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines the arbitrary waveform generator with the oscilloscope into a single integrated measurement device. The control unit of the oscilloscope is extended to function as an arbitrary waveform generator, allowing the device to both measure and generate signals. This merging eliminates the need for separate external signal generation equipment while maintaining full functionality.
Solution Approach 2:
The control unit of the oscilloscope is designed to perform multiple functions: it can operate as a traditional oscilloscope for signal measurement and analysis, and simultaneously function as an arbitrary waveform generator for signal generation. This multi-functionality allows a single device to replace multiple separate instruments, reducing complexity while improving versatility.
2Adaptability or versatility
If an external arbitrary waveform generator is connected to the measurement setup, then the ability to generate appropriate output signals is improved, but the setup requires more space and additional equipment
Solution Approach 1:
The arbitrary waveform generation capability is merged into the oscilloscope housing, eliminating the need for separate external equipment. The control unit serves dual purposes as both measurement and signal generation device, consolidating what would traditionally require multiple separate instruments into one compact unit.
3Measurement precision
If a specific tag is required for testing devices under test, then the accuracy of the measurement is improved, but the adaptability of the measurement device decreases
Solution Approach 1:
The arbitrary waveform generator creates copies of the expected response signals that a actual tag would generate. Instead of requiring a physical tag, the system generates digital replicas of the tag's response signals, allowing accurate measurement and testing without the need for physical tags or specialized test equipment.
