Problem
Current production lines face delays and incompatibility issues when manufacturing Macintosh system computers and peripherals, leading to errors in data transmission and incorrect labeling of electronic products due to the use of different operating systems.
Innovation Solution
An electronic device test system utilizing a Macintosh system computer to detect memory serial numbers and transmit them via an RS232 interface to a Windows system computer for comparison and printing, using analog keyboard events to ensure accurate data input and printing, thereby avoiding network-related delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is transmitted by means of wired/wireless network, then data can be transmitted between Macintosh system computer and Windows system computer, but delay easily occurs during transmission
Solution Approach 1:
The patent introduces an RS232 interface as an intermediary communication channel between the Macintosh system computer and Windows system computer. This serial interface acts as a mediator that enables direct data transmission without relying on network protocols, thereby eliminating network-induced delays while maintaining compatibility between different operating systems.
2Reliability
If Macintosh system computer is used for testing Macintosh system products, then compatibility between systems is improved, but data transmission delay occurs when transmitting to Windows system computer
Solution Approach 1:
The patent segments the data transmission process into two distinct stages: first, the Macintosh system computer detects and processes data locally without network delays; second, the processed data is transmitted via RS232 interface to the Windows system computer for printing. This segmentation allows each system to operate in its optimal environment while minimizing cross-system communication delays.
3Ease of manufacture
If Windows system computer is used for printing, then printing function is available, but data transmission delay causes incorrect labeling
Solution Approach 1:
The patent implements preliminary action by having the Macintosh system computer complete all data detection, processing, and validation operations before transmitting the final processed data to the Windows system computer via RS232 interface. This ensures that the printing process receives ready-to-use, accurately processed data, eliminating delays and errors that would otherwise occur during data transmission and processing.

AI summary
An electronic device test system and method detects a memory serial number of an electronic device. The electronic device test system includes a Macintosh system computer, configured to execute a serial number detection program to detect the memory serial number of the electronic device; and a Windows system computer, configured to execute a serial number comparison program to compare whether the memory serial number of the electronic device satisfies a coding rule. The Macintosh system computer transmits the memory serial number to the Windows system computer by means of an RS232 interface for printing.
