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

VSEngineering 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

Engineering Contradiction:
Improvepayment functionalityVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improvepayment capabilityVSAvoidsystem architecture
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation
