Dual-Core Wearable Payment Architecture for Low-Power Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart wearable devices with payment functions are limited to high-performance systems and cannot operate efficiently in low-performance systems, restricting their functionality.
Innovation Solution
Implementing a dual-core, dual-system architecture in wearable devices with a high-performance first processor and a low-power consumption second processor, enabling payment transactions through a low-power second system while utilizing the high-performance first system only when necessary for generating payment graphic codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If payment function is implemented on low-performance wearable devices, then power consumption increases and standby time decreases, but if payment function is restricted to high-performance devices only, then power consumption is high but payment functionality is limited
Solution Approach 1:
The system is divided into two distinct processors: a first processor for high-performance operations and a second processor for low-power operations. The payment function is segmented such that the low-performance second processor handles basic payment operations while the high-performance first processor provides support when needed, allowing payment functionality on low-power devices without continuously consuming high power.
Solution Approach 2:
The system dynamically switches between the first processor and the second processor based on operational requirements. During payment transactions, the second processor activates the first processor as needed rather than maintaining it in a continuous high-power state, enabling dynamic power management that adapts to the actual payment operation needs.
2Adaptability or versatility
If dual-core communication is used to enable payment on low-performance system, then payment functionality is achieved, but system complexity increases
Solution Approach 1:
The communication system is segmented into two distinct communication interfaces: a first communication interface for the high-performance processor and a second communication interface for the low-power processor. This segmentation allows each processor to operate independently with its own communication protocol, simplifying the overall system architecture while enabling payment functionality through coordinated dual-core communication.
