Innovation Solution
A calibration detection system comprising a processor, evaluation apparatus with signal generators and measurement devices, and a connection apparatus with internally switchable leads, which allows all connections to be established initially and switched as needed to perform testing protocols, reducing the need for frequent reconnections and minimizing human error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual connection procedures are used for calibration testing, then technicians can perform measurements with basic equipment, but the process becomes time-consuming and labor-intensive due to repeated connections and reconnections
Solution Approach 1:
The system pre-positions multiple leads and test equipment connections in place before the calibration procedure begins. All necessary connections are established upfront, allowing the technician to simply select different measurement points without physically reconnecting equipment during the procedure.
Solution Approach 2:
A switch matrix serves as an intermediary device between the test equipment and the electronic apparatus under test. This switch matrix allows rapid reconfiguration of connections without requiring physical disconnection and reconnection of leads, thereby maintaining productivity while minimizing time loss.
2Reliability
If complex testing protocols with multiple connection changes are followed, then comprehensive calibration can be achieved, but the complexity increases the potential for human error
Solution Approach 1:
The switch matrix acts as a controlled intermediary that manages the complexity of multiple connections. Instead of the technician manually managing complex connection changes, the switch matrix systematically routes signals according to the test protocol, reducing human error while maintaining comprehensive calibration capability.
Solution Approach 2:
The system automatically manages its own connection configuration through the switch matrix, which can be programmed to make appropriate connection changes based on the test protocol being executed. This self-service capability reduces reliance on technician skill and minimizes errors.
3Adaptability or versatility
If multiple leads are physically reconnected during calibration procedures, then different measurement points can be tested, but the labor-intensive nature of the task increases
Solution Approach 1:
All necessary leads and test equipment are connected to the electronic apparatus under test before the calibration procedure begins. This preliminary setup maintains versatility for testing multiple measurement points while eliminating the need for repeated physical connections during the procedure.
Solution Approach 2:
The switch matrix serves as an intermediary that provides measurement point flexibility without requiring physical reconnection of leads. By internally switching connections within the switch matrix, the system maintains adaptability for different measurement points while greatly simplifying the operator's task.

AI summary
An improved calibration detection system for use in calibrating an electronic apparatus includes a processor apparatus, an evaluation apparatus, and a connection apparatus. The connection apparatus includes a plurality of leads and is operated by the processor apparatus to internally switch and connect the various leads with various elements of the evaluation apparatus. By enabling all of the leads to be connected at the outset with the electronic apparatus and by internally switching the connections between the leads and the various elements of the evaluation apparatus, the calibration detection system saves time and avoids error in performing a testing protocol.
