Solution Overview

Problem

Mobile terminals lack efficient methods for convenient and secure payment processing in specific geographic areas, requiring users to manually select payment methods each time, which is inconvenient and time-consuming.

Innovation Solution

A mobile terminal system that allows users to set specific geographic areas and corresponding payment methods, enabling automatic selection and use of payment methods when entering predefined areas through NFC tagging, ensuring seamless and secure transactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual selection of payment methods is required each time, then payment security can be maintained, but user convenience deteriorates and operation time increases

Engineering Contradiction:
Improvepayment operation convenienceVSAvoidtime for payment method selection
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary action by pre-configuring payment methods associated with specific locations or merchants before the actual payment transaction. When a user approaches a registered location or selects a merchant, the system automatically retrieves and presents the pre-configured payment method, eliminating the need for manual selection during the transaction and reducing operation time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The payment system implements self-service by automatically selecting and executing the appropriate payment method based on pre-established criteria such as location, merchant type, or user preferences. The system serves itself by making intelligent decisions about payment processing without requiring active user intervention for method selection, thereby improving operational convenience.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If automatic payment method selection is implemented, then operation convenience is improved, but system complexity increases

Engineering Contradiction:
Improvepayment processing convenienceVSAvoidpayment system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system applies segmentation by dividing the payment method selection logic into separate, manageable modules: location-based payment rules, merchant-based payment rules, and user preference settings. Each module operates independently and can be configured or modified without affecting the entire system, making the complexity manageable while enabling automatic selection functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

An intermediary component or decision engine is introduced to mediate between the user's payment needs and the available payment methods. This intermediary layer processes the selection logic automatically, shielding the user from system complexity while providing convenient automatic payment method selection. The intermediary handles the complexity of matching users with appropriate payment methods based on various criteria.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple payment methods are available for different areas, then adaptability is improved, but ease of operation deteriorates due to manual selection requirements

Engineering Contradiction:
Improvepayment method adaptability to different areasVSAvoidpayment method selection ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs preliminary configuration by establishing which payment methods are valid for specific locations, merchants, or service types before the user needs to make a payment. This pre-establishment of payment method adaptability allows the system to automatically match the appropriate method when a user is at a registered location, maintaining versatility while simplifying operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms that detect the user's current context (such as location or selected merchant) and automatically respond by presenting the most suitable payment method. This feedback loop maintains adaptability to different areas while improving ease of operation by eliminating manual selection, as the system feedback-driven selection presents only the relevant payment options based on real-time context.

Inventive Principle:
Principle #23Feedback
