Switching Portion for Dynamic Tester Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing testing systems require program changes or system shutdowns when adding or removing test devices, limiting their effective use.
Innovation Solution
A testing system with a switch portion that selects the appropriate testing portion based on test item information, allowing easy connection or disconnection of test devices without altering the program or stopping the system, utilizing multiple test applying and testing portions connected via a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new tester is connected or the tester is disconnected in the testing system, then the testing system can be adapted to different configurations, but the program has to be changed or the testing system has to be stopped
Solution Approach 1:
The controller预先 acquires test item information from each testing portion before actual testing begins. This preliminary acquisition of capability information allows the system to automatically manage tester connections and disconnections without program changes or system shutdowns, resolving the contradiction between adaptability and productivity
Solution Approach 2:
The system implements feedback by having each testing portion report its test capability information to the controller. The controller uses this feedback information to automatically select appropriate testing portions and manage connections, enabling dynamic reconfiguration without stopping the system or changing programs
2Adaptability or versatility
If the program is changed to accommodate new or disconnected testers, then the testing system can adapt to configuration changes, but the system operation is interrupted and efficiency is reduced
Solution Approach 1:
The controller预先 acquires and stores test item information from all testing portions before configuration changes occur. This preliminary preparation enables the system to handle tester additions or removals dynamically without program changes or shutdowns, eliminating time loss while maintaining adaptability
Solution Approach 2:
The system transitions from a static program-based configuration to a dynamic system where the controller automatically selects testing portions based on real-time capability information. This dynamic approach allows configuration changes without interruption, resolving the contradiction between adaptability and time loss

AI summary
A testing system includes a plurality of test applying portions and a plurality of testing portions, each test applying portion having a test device that generates an output signal and each testing portion tests the output signal of the test device, in response to the test applying portion. The testing system further includes a switch portion that switches the output signal of the test device between the test applying portions and the testing portions. The test applying portion has a selecting portion that selects the testing portion through the switch portion for testing the output signal according to test item information, the test item information including information about a test capability of the testing portion.
