Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional chip testing methods are used, then testing capability is maintained, but batch testing efficiency deteriorates due to high communication requirements and difficulty in controlling multiple platforms simultaneously
Solution Approach 1:
The patent merges multiple test platforms into a unified batch testing system where a single test program can control multiple platforms simultaneously. By combining platform identification, test case distribution, and result collection into one integrated workflow, the system achieves efficient batch testing without requiring complex individual communication with each platform.
Solution Approach 2:
The test program is designed with universal functionality to adapt to multiple test platforms through platform identification mechanisms. The same test program can be distributed to different platforms and executed autonomously on each, eliminating the need for separate communication protocols or customized test programs for each platform.
2Productivity
If conventional testing methods are used, then individual device testing is performed, but supply efficiency deteriorates due to inability to perform batch testing
Solution Approach 1:
The patent segments the batch testing process into independent, parallel-executable test cases that can be distributed to multiple platforms simultaneously. Each platform executes its assigned test case autonomously, and results are collected independently, enabling supply chain efficiency improvement without increasing operational complexity.
Solution Approach 2:
The system performs preliminary actions by pre-distributing test cases to multiple platforms before actual testing begins. Platform identification and test case assignment are completed in advance, allowing parallel execution of tests across multiple devices, thereby improving supply efficiency without requiring complex real-time coordination.
3Adaptability or versatility
If conventional testing methods are used, then testing can be performed, but portability of test program deteriorates due to platform-specific requirements
Solution Approach 1:
The patent employs parameter changes by introducing platform identification parameters that allow the same test program to adapt to different platforms. The test program reads platform-specific parameters (such as device identifiers) at runtime and adjusts its execution accordingly, maintaining high portability while ensuring reliable communication through standardized parameter interfaces.
Solution Approach 2:
The system introduces an intermediary mechanism in the form of platform identification and parameter passing layers between the universal test program and specific test platforms. This intermediary layer enables the test program to communicate with different platforms through a standardized interface, improving portability while maintaining communication reliability through the mediator's coordination.
