Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separately formed test and measurement device is used to test mobile communication devices, then testing can be performed with dedicated test equipment, but the system complexity increases and testing time increases
Solution Approach 1:
The patent merges the test and measurement device with the device under test into a single integrated mobile communication device. The testing module is integrated into the communication device itself, eliminating the need for separate external test equipment. This integration reduces system complexity while maintaining full testing capability, as the device can test itself and other devices using its own communication and processing resources.
Solution Approach 2:
The mobile communication device is designed with multi-functionality, serving both as a communication device and as a testing device. The testing module can test the device itself (self-testing) and other communication devices, making the device universal in its functionality. This eliminates the need for dedicated test equipment and reduces overall system complexity.
2Measurement precision
If a separately formed test and measurement device is used, then protocol testing can be performed, but the testing method takes a long time especially when testing many devices
Solution Approach 1:
The device performs self-testing through the integrated testing module, eliminating the need for external test equipment setup and operation. The device uses its own communication module and processing resources to conduct protocol testing, which significantly reduces testing time especially when testing multiple devices, as each device can test itself without requiring external test device intervention.
Solution Approach 2:
The testing module is pre-integrated into the device during manufacturing, with the communication protocol tester and stacking unit already configured. This preliminary integration means that when testing is needed, no additional setup or configuration of external test equipment is required, immediately reducing testing time while maintaining protocol testing precision.
3Measurement precision
If separate test units with protocol test generation and processing units are used, then comprehensive protocol testing can be achieved, but the cost and complexity increase
Solution Approach 1:
The patent combines the protocol test generation and processing functions into the device's own testing module, eliminating the need for separate external test units. The communication protocol tester and stacking unit are integrated into the device's existing communication infrastructure, reducing manufacturing costs while maintaining comprehensive protocol testing capability.
Solution Approach 2:
The integrated testing module provides universal testing capability that can test various communication protocols and device functions without requiring separate specialized test equipment for each protocol. This multi-functionality reduces the overall cost of testing systems while maintaining comprehensive testing coverage.
