Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile devices are used as wireless peripherals connected to stationary POS terminals, then mobility and flexibility are improved, but independent POS functionality and computing power are insufficient
Solution Approach 1:
The patent merges the functionality of a stationary POS terminal with mobile device portability by integrating a processor, touchscreen interface, card reader, and wireless transceiver into a single portable unit. This combination enables the device to function as an independent POS terminal while maintaining mobility, directly resolving the contradiction between mobility and independent functionality.
Solution Approach 2:
The portable POS device is designed with multi-functional capabilities including magnetic stripe card reading, chip card processing, wireless communication, and touchscreen operation. This universality allows the single device to perform various POS functions that previously required separate stationary terminals and peripherals, achieving both mobility and full POS functionality.
2Adaptability or versatility
If a portable device is designed with integrated POS components, then independent transaction processing capability is improved, but device size and complexity increase
Solution Approach 1:
By consolidating multiple POS components (processor, display, card reader, wireless module) into a single integrated unit, the patent reduces overall system complexity compared to using separate stationary terminals and peripherals. The merged design achieves independent transaction processing while minimizing device size through efficient component integration.
3Ease of manufacture
If existing mobile devices are customized with POS software, then connectivity to stationary POS is improved, but transaction functionality and computing power are limited
Solution Approach 1:
The patent extracts the computing core from the stationary POS terminal and relocates it to the portable device. By incorporating a dedicated processor and sufficient memory directly in the mobile unit, the device gains independent computing power to handle transactions locally without relying on a centralized stationary system, thus overcoming the computing power limitation of software-customized mobile devices.
