Solution Overview

Problem

Existing settlement systems using wearable devices require users to manually start up their mobile terminals for settings, leading to reduced user convenience.

Innovation Solution

A settlement system that includes a wearable device capable of acquiring and transmitting setting information related to a settlement service directly from a user's portable terminal, reducing the processing load on the portable terminal and enhancing user convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the wearable device displays settlement codes and requires portable terminal for settings, then the settlement service can be provided, but user convenience deteriorates due to manual terminal startup requirements

Engineering Contradiction:

Improveuser convenienceVSAvoidsystem operation complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The wearable device automatically acquires setting information from the portable terminal without requiring user intervention to manually start the terminal or configure settings. The system performs self-service by autonomously retrieving and applying settlement service settings, thereby improving user convenience while maintaining service functionality.

Inventive Principle:

Principle #25Self-service

2Reliability

If the portable terminal handles all settlement processing, then settings can be managed centrally, but processing load increases causing potential display failures

Engineering Contradiction:

Improvedisplay reliabilityVSAvoidprocessing load

Core Design Contradiction:

ReliabilityVSPower

Solution Approach 1:

The settlement processing function is segmented between the portable terminal and wearable device. The portable terminal retains responsibility for settings management and code generation, while the wearable device handles local display and settlement execution. This segmentation reduces the processing load on the portable terminal, preventing display failures while maintaining centralized settings control.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If the wearable device operates independently without portable terminal connection, then user convenience improves, but ability to acquire settings deteriorates

Engineering Contradiction:

Improveuser convenienceVSAvoidsettings information

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The wearable device acquires setting information from the portable terminal in advance before settlement operations are needed. By performing this data acquisition preliminarily and storing it locally, the device can operate independently during settlement transactions without real-time connection to the terminal, thus improving convenience while preventing loss of settings information.

Inventive Principle:

Principle #10Preliminary action

AI summary

A settlement system includes at least one processor that acquires setting information regarding settings related to a settlement service, the settings being designated on a user's portable terminal in the settlement service, and transmits the setting information to a wearable device that is connectable to the portable terminal.
