Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional electronic wallet balance display systems require user interaction and rely on servers for notifications, which are costly and limited to balance decreases, and may lead to misunderstandings in transaction data displayed to users, compromising privacy and convenience.

Innovation Solution

A cellular telephone device with a non-contact type IC card processing section that performs wireless communication with external equipment to automatically detect updates in monetary value data and provide notifications using existing cellular telephone functions, eliminating the need for special equipment and ensuring user awareness of transaction details without requiring user operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional electronic wallet balance display systems are used, then user interaction is required to check balance, but this reduces convenience and requires user operation

Engineering Contradiction:

Improveconvenience of checking balanceVSAvoidautomatic balance notification

Core Design Contradiction:

Ease of operationVSExtent of automation

Solution Approach 1:

The system automatically detects balance updates and sends notifications without requiring user action. The cellular telephone device autonomously monitors the electronic wallet balance and initiates notification transmissions when changes are detected, eliminating the need for users to manually check balances.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements automatic feedback by detecting balance changes and immediately notifying the user. When the balance is updated, the system automatically generates and sends a notification message back to the user, creating a closed-loop feedback mechanism that keeps users informed without manual intervention.

Inventive Principle:

Principle #23Feedback

2Reliability

If server-based E-mail notification systems are used, then balance update notifications can be provided, but communication costs and server requirements increase system complexity

Engineering Contradiction:

Improvenotification deliveryVSAvoidserver and communication infrastructure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The notification functionality is extracted from the server infrastructure and integrated directly into the cellular telephone device. The device itself performs the detection and notification functions that would otherwise require external server support, eliminating the need for complex server-based E-mail notification systems.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The cellular telephone device performs multiple functions: it serves as both the electronic wallet storage medium and the notification system. By utilizing the device's existing communication capabilities, the system eliminates the need for separate server infrastructure, reducing overall system complexity while maintaining reliable notification delivery.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Loss of information

If accounting terminal displays transaction data, then transaction information is provided to users, but privacy concerns and potential misunderstandings arise

Engineering Contradiction:

Improvetransaction information accuracyVSAvoidprivacy exposure and misunderstanding

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The system uses automatic notification messages as an intermediary to convey transaction information. Instead of displaying detailed transaction data on accounting terminals that users must interpret, the system sends direct, clear notifications to users, eliminating potential misunderstandings and protecting privacy by avoiding public display of sensitive information.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates a simplified copy of transaction information in the form of notification messages that are sent directly to users. This copy contains only the essential information needed for user awareness, eliminating the need for users to interpret complex displays at accounting terminals and reducing privacy exposure.

Inventive Principle:

Principle #26Copying
