Hot-Plug Testing System With Self-Registering Test Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing testing systems require program changes or system shutdowns when adding or removing test devices, limiting their effectiveness and productivity.
Innovation Solution
A testing system with multiple test applying and testing portions, and a switch portion that allows easy connection or disconnection without altering the program or stopping the system, utilizing test information to select and perform tests on designated items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new tester is added or removed in the testing system, then the testing capability is improved or adjusted, but the program must be changed or the system must be stopped
Solution Approach 1:
The testing portion automatically performs self-identification and self-registration with the test applying portion when connected to the system. The test information portion outputs test item information including test capability, and the testing portion is automatically recognized and registered without requiring manual program changes, enabling the system to adapt to configuration changes while maintaining continuous operation
Solution Approach 2:
The system dynamically changes operational parameters by switching between different test information based on which testing portions are connected. The test applying portion selects appropriate test information from multiple available options based on the current configuration, allowing the system to adapt to different testing portions without program modifications
2Adaptability or versatility
If the testing system is stopped to add or remove testers, then the configuration is updated, but system availability decreases
Solution Approach 1:
The testing system maintains continuous operation during configuration changes. The hot-plug capability allows testers to be added or removed while the system remains operational, with the test applying portion automatically detecting and adapting to the changed configuration without interruption to the testing process
Solution Approach 2:
The system configuration is made dynamic rather than static. The test information is selected based on real-time connection status of testing portions, allowing the system to automatically adapt its behavior according to the current configuration without requiring manual intervention or system shutdown
3Adaptability or versatility
If program changes are required when adding or removing testers, then the system is customized, but the complexity of operation increases
Solution Approach 1:
The testing portion performs automatic self-identification and self-registration by outputting its test item information including test capability. The test applying portion automatically receives and processes this information to register the new testing portion, eliminating the need for manual program modification and reducing operational complexity
Solution Approach 2:
The system automatically changes operational parameters by selecting appropriate test information based on the connected testing portions. This dynamic parameter selection replaces manual program customization, allowing system adaptation through automatic parameter adjustment rather than complex program changes

AI summary
A testing system including a plurality of test applying portions that operate a test device for outputting an output signal; a plurality of testing portions that test the output signal of the test device; and a switch portion that switches the output signal between the test applying portions and the testing portions. The testing portions each have a test information portion that outputs test item information which includes a test capability of the testing portion, and have a test performing portion which is selected under the test item information that receives the output signal from the test applying portion through the switch portion, and performs a test under a designated test item.
