Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-stage port module is used to provide various ports, then the functionality and versatility of the POS terminal is improved, but the thickness of the terminal increases, restricting installation in limited spaces
Solution Approach 1:
The patent combines multiple port modules (USB port module, hard disk port module, audio port module, etc.) into a single integrated one-stage port module unit. This merging approach maintains all necessary port functionalities while reducing the overall thickness of the POS terminal by eliminating multi-stage stacking.
Solution Approach 2:
The patent transitions from a multi-stage vertical arrangement to a one-stage horizontal integration, redistributing port modules across the front surface in a single plane. This dimensional reorganization maintains port accessibility while significantly reducing the terminal's thickness.
2Device complexity
If separate USB cable and disk cable are used for external connections, then the device complexity is reduced, but electrical malfunctions occur due to connection failures and communication errors increase
Solution Approach 1:
The patent extracts the USB port and hard disk port from external cable connections and integrates them directly into the main board as built-in port units. This extraction eliminates the intermediate cable connection layer, removing the source of connection failures while maintaining simplified device architecture.
Solution Approach 2:
The patent eliminates the cable as an intermediary component between external devices and the main board. By providing direct integrated ports on the main board, the system removes the cable mediator that causes connection failures, achieving both simplicity and reliability.
3Ease of manufacture
If separate USB cable and disk cable are used for external connections, then the ease of manufacture is improved, but high-speed communication is limited due to slow transmission speed
Solution Approach 1:
The patent extracts the communication pathway from the cable-mediated route and creates a direct connection path through integrated ports on the main board. This extraction eliminates the speed-limiting cable transmission环节 while maintaining manufacturing simplicity through standardized port integration.

AI summary
The present invention has advantages in that as a USB port unit and a hard disk port unit are formed on the edge of the substrate unit thereby allowing external USB and external disks to be directly connected to the main board, so that it prevents electrical malfunction caused by cable connection, and as the transmission speed of high-speed communication increases through direct connection, it is to provide a main board for POS terminal which may maintain stable system by reducing communication errors.
