Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual monitoring is used to detect silver paste activation state, then workers can actively monitor current value and duration, but it consumes significant time and labor costs
Solution Approach 1:
The patent replaces the manual mechanical monitoring system with an automated electrical detection system. The test module automatically measures voltage across the silver paste to determine activation state, eliminating the need for manual current monitoring and time-consuming worker intervention while maintaining reliable detection accuracy.
Solution Approach 2:
The detection system enables the silver paste activation process to self-monitor and self-report its state. The test module continuously monitors voltage and automatically determines when activation is complete, allowing the process to detect its own activation state without external manual intervention, thereby reducing both time and labor costs.
2Reliability
If manual activation monitoring is implemented, then workers can detect activation state, but it requires active worker intervention and increases labor costs
Solution Approach 1:
The patent substitutes manual worker intervention with an automated electrical measurement system. The test module uses voltage measurement across the silver paste to automatically determine activation state, replacing the mechanical act of worker monitoring and decision-making with an automated electrical detection and control system.
Solution Approach 2:
The patent introduces a test module as an intermediary between the silver paste and the detection process. This intermediary automatically measures voltage, processes the signal, and determines activation state, serving as a mediator that eliminates the need for direct worker intervention while ensuring reliable detection.
3Reliability
If conventional manual activation process is used, then workers can monitor current parameters, but it reduces productivity due to time consumption
Solution Approach 1:
The patent replaces manual batch-by-batch monitoring with automated parallel detection. The test module can simultaneously monitor multiple silver paste applications, automatically measuring voltage and determining activation state for each, thereby dramatically increasing batch detection efficiency while maintaining reliable results.
Solution Approach 2:
The test module is designed with universal functionality to handle multiple detection tasks simultaneously. It can monitor current, voltage, and time parameters across multiple silver paste applications using the same automated system, enabling batch processing and significantly improving overall productivity without sacrificing detection reliability.

AI summary
Provided is a silver paste activation detecting system, including a power supply module, a test fixture electrically connected to the power supply module and configured to load the module to be tested to form a closed loop, a resistor element connected in series in the closed loop and a test module connected in parallel to the resistor element. The test module detects a voltage value across the resistor element after the conductive silver paste is energized for at least two seconds. When the voltage value is greater than or equal to a predetermined voltage value, the test module determines that the conductive silver paste is activated. When the voltage value is less than the predetermined voltage value, the conductive silver paste is not activated. The system can realize automatic detection of the activation state of the conductive silver paste, thereby greatly saving time and labor costs.
