Testing Slot Abnormality Detection for Inspection Line Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In inspection production lines, existing systems face challenges in accurately identifying abnormal testing slots to prevent misjudgment of good products and optimize machine capacity, leading to inefficiencies and increased costs.
Innovation Solution
A method for operating a testing system that involves comparing current testing data with former data to determine abnormality, shutting down abnormal slots, performing a confirmation procedure, and restarting them after repair, with predetermined conditions for shutting down and passing criteria stored in a cloud database to ensure reliability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic abnormality determination is implemented to identify substandard products, then production quality control is improved, but the complexity of the testing system increases
Solution Approach 1:
The testing system is divided into multiple independent testing slots, each capable of autonomous abnormality determination. The controller segments the monitoring function by comparing measurement data from each slot against stored judgment conditions independently, allowing distributed decision-making that reduces central system complexity while maintaining overall reliability.
Solution Approach 2:
Judgment conditions and specifications are pre-stored in the controller before testing begins. The system performs preliminary setup of acceptance criteria, measurement thresholds, and shutdown conditions, eliminating the need for complex real-time decision logic during operation and simplifying the runtime system architecture.
2Productivity
If multiple testing slots operate simultaneously to increase productivity, then production efficiency is improved, but the difficulty of detecting and measuring abnormalities increases
Solution Approach 1:
Each testing slot operates as an independent monitoring unit with its own abnormality detection logic. The controller receives measurement data from multiple slots simultaneously and processes each slot's data independently against its specific judgment conditions, allowing parallel operation while maintaining simple, slot-specific detection rules that reduce overall system complexity.
3Measurement precision
If automatic shutdown of abnormal slots is implemented to prevent misjudgment, then measurement precision is improved, but the loss of time for confirmation and repair increases
Solution Approach 1:
The system pre-stores multiple levels of judgment conditions (shutdown conditions, confirmation conditions, restart conditions) before operation. When an abnormality is detected, the predetermined confirmation procedure is automatically initiated, eliminating the need for manual judgment and reducing confirmation time while maintaining high precision through multiple staged verification criteria.
Solution Approach 2:
The system implements a feedback loop where abnormal slot shutdown triggers an automatic confirmation procedure. The controller continuously monitors the shutdown slot and automatically initiates restart procedures when normal operation is confirmed, creating a closed-loop system that reduces manual intervention time while maintaining high detection accuracy through iterative verification.

AI summary
A method of operating a testing system comprising a plurality of testing slots. The method comprising: testing the testing slots; obtaining a current testing data from the testing slots; determining whether one of the testing slots is abnormal by comparing the current testing data with a former testing data; shutting down the one of the testing slots and sending a repairing notification if the one of the testing slots is determined to be abnormal; performing a confirmation procedure to determine whether the one of the testing slots is repaired to be normal; and restarting the one of the testing slots if the one of the testing slots passes the confirmation procedure.
