Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If device verification is performed by actually operating the device under test, then verification accuracy is improved, but power consumption increases and test time extends
Solution Approach 1:
The patent creates a virtual copy of the device under test in the virtualization layer, allowing verification operations to be performed on the virtual device rather than the physical device. This copying approach maintains verification accuracy while preventing actual power consumption and operational wear on the physical device.
Solution Approach 2:
The patent introduces a virtualization layer as an intermediary between the physical device and the verification system. This intermediary layer enables verification operations to be performed on virtual representations, reducing direct interaction with the physical device and thereby lowering power consumption and test time.
2Measurement precision
If device verification is performed by actually operating the device under test, then verification accuracy is improved, but test time extends
Solution Approach 1:
The patent creates a virtual copy of the device under test in the virtualization layer, allowing verification operations to be performed on the virtual device rather than the physical device. This copying approach maintains verification accuracy while enabling parallel testing and faster operation cycles, thereby reducing overall test time.
Solution Approach 2:
The patent performs preliminary virtualization of the device, creating a virtual representation that can be used for verification before actual physical testing is needed. This preliminary action enables faster iteration and reduces the time required for repeated verification cycles.
3Reliability
If device verification is performed by actually operating the device under test, then comprehensive verification is improved, but device wear increases
Solution Approach 1:
The patent creates a virtual copy of the device under test in the virtualization layer, allowing comprehensive verification operations to be performed on the virtual device rather than the physical device. This copying approach enables thorough testing including stress tests and edge cases without causing physical wear or degradation to the actual device.
Solution Approach 2:
The patent uses virtualization as a protective measure before physical testing, allowing potential failures and stress conditions to be tested in the virtual environment first. This beforehand cushioning prevents harmful effects from transferring to the physical device, thereby extending its lifespan while maintaining verification comprehensiveness.
4Reliability
If device verification is performed by actually operating the device under test, then real-world performance verification is improved, but operational risks increase
Solution Approach 1:
The patent creates a virtual copy of the device under test that accurately replicates real-world operating conditions and performance characteristics. This virtual copy enables real-world performance verification through realistic simulation while isolating the physical device from harmful operational risks such as failures, crashes, or unsafe conditions.
Solution Approach 2:
The patent converts the potential harm of operational risks into a benefit by using virtualization to simulate risky scenarios. What would normally be harmful operations on the physical device are transformed into safe virtual operations, allowing comprehensive real-world performance verification without exposing the physical device to actual dangers.
