Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing technologies do not allow for payment processing in an offline state, limiting user convenience as they require end-user devices to be online to exchange service data with a server.

Innovation Solution

Establishing a communication connection between a collection device and a payment device in an offline state, enabling the payment device to process payment data and return results to the collection device for further processing, allowing offline payment transactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If payment processing requires online state to exchange service data with server, then service processing can be completed through server, but user convenience is reduced when device is offline

Engineering Contradiction:

Improveuser convenienceVSAvoidpayment processing capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The payment processing function is segmented into two independent parts: a collection device that collects payment data and a payment device that processes payments. Each device can operate independently in offline mode, exchanging data through direct communication connections without requiring server involvement for basic payment processing.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A communication connection is established as an intermediary between the collection device and payment device, enabling direct data exchange. This intermediary channel allows the devices to communicate and process payments offline without relying on the server as an intermediary.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If device must be in online state to process payment, then server can be accessed for payment processing, but payment processing cannot be performed when device is offline

Engineering Contradiction:

Improvepayment processing capabilityVSAvoiduser convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The payment device is designed to perform payment processing autonomously in offline mode. It can collect payment data, process the payment using stored account information, and return results without requiring continuous server connection, enabling self-service payment processing.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If communication connection is established between collection device and payment device in offline state, then offline payment processing is enabled, but device complexity increases

Engineering Contradiction:

Improveoffline payment capabilityVSAvoidcommunication connection establishment

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The collection device and payment device are designed with multi-functionality to handle both online and offline modes. The same devices can establish communication connections for offline payment processing or connect to servers for online processing, eliminating the need for separate dedicated hardware for each mode.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adapts its communication mode based on device state. When offline, devices establish direct communication connections; when online, they connect to servers. This dynamic switching capability allows the system to respond to varying network conditions without requiring complex dedicated infrastructure for each scenario.

Inventive Principle:

Principle #15Dynamics

AI summary

One or more implementations shown in the present specification provide an offline payment method. A communication connection between a collection device and a payment device is established, wherein both the collection device and the payment device are in an offline state. Payment data sent by the collection device is received by the payment device through the communication connection established to the collection device. Payment processing based on the payment data and account information of the payment device is performed by the payment device, to obtain a payment result. The payment result is returned, by the payment device to the collection device through the communication connection. Collection processing is performed, by the collection device, based on the payment result and obtained account information of the payment device, to obtain a collection result.
