Solution Overview
Problem
Current point of sale (POS) systems in retail and commercial environments often rely on expensive custom-built hardware and have limited technology integration, leading to inefficient resource utilization and high capital investments.
Innovation Solution
A POS electronic system that includes a mobile data processing system with a first data port configured to communicate using a first data protocol, and a peripheral device with a second data port using a different protocol, facilitated by controller modules for data conversion between protocols, enabling efficient communication and transaction processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If custom-built hardware is used for POS systems, then transaction processing capability is improved, but capital investment cost increases
Solution Approach 1:
The patent applies universality by enabling a mobile device to perform multiple POS functions (scanning, data processing, communication, transaction management) that were previously dedicated to custom-built hardware. The mobile device's existing hardware resources are leveraged to replace specialized POS equipment, reducing capital investment while maintaining transaction processing capability.
Solution Approach 2:
The patent substitutes mechanical/custom-built hardware systems with a software-based solution running on a mobile device. The POS functionality is implemented through software applications and data processing algorithms rather than dedicated hardware circuits, thereby reducing hardware costs while preserving functional capabilities.
2Quantity of substance
If standardized hardware is used for POS systems, then capital investment is reduced, but technology integration capability deteriorates
Solution Approach 1:
The patent introduces an intermediary layer of software and communication protocols that enable the mobile device to integrate with various peripheral devices (barcode scanners, RFID readers, scales). This software intermediary translates and manages data exchange between standardized hardware components, providing technology integration capability without requiring custom-built hardware.
Solution Approach 2:
The patent utilizes parameter changes in communication protocols and data formats to enable compatibility between the mobile device and diverse peripheral devices. By dynamically adjusting communication parameters and using standardized interfaces, the system achieves versatile technology integration using off-the-shelf hardware components.
3Quantity of substance
If mobile devices are used for POS transactions, then hardware cost is reduced, but data communication protocol compatibility deteriorates
Solution Approach 1:
The patent employs software intermediaries and protocol translation layers that enable the mobile device to communicate with peripheral devices using different data protocols. The system acts as a mediator, converting between various communication protocols (Bluetooth, WiFi, serial, USB) and the mobile device's native interfaces, thereby maintaining protocol compatibility without increasing hardware complexity.
