Solution Overview

Problem

Current network payment systems require both the payee and payer to be online for verification, imposing high calculation demands and network bandwidth requirements, and only verify one party's code, leading to low security.

Innovation Solution

A task processing system utilizing two-way verification through Bluetooth connection between intelligent devices, including a first intelligent device generating an identification code and a second device verifying it, establishing a Bluetooth connection, and processing the task upon successful verification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If network payment verification is performed online, then payment security can be maintained through centralized verification, but high calculation demands and network bandwidth requirements are imposed

Engineering Contradiction:

Improvepayment securityVSAvoidcalculation demand

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The verification process is segmented into two independent verification stages: first verification of the identification code and second verification of the task execution instruction. This segmentation allows verification to be distributed between the two intelligent devices rather than centralized in one device, reducing the calculation burden on a single device while maintaining security through multi-stage verification

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first intelligent device performs preliminary verification by verifying the task execution instruction before executing the payment task. This preliminary action ensures that verification is completed in advance, reducing the need for complex real-time calculation during the actual payment processing, thereby lowering calculation demands

Inventive Principle:

Principle #10Preliminary action

2Reliability

If network payment verification is performed online, then centralized control can be maintained, but network bandwidth requirements increase

Engineering Contradiction:

Improvepayment securityVSAvoidnetwork bandwidth requirement

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The verification process is extracted from the network environment and performed locally between the two intelligent devices using Bluetooth communication. By taking out the verification function from the network-dependent online process and implementing it as an offline local process, the system maintains payment security without requiring network bandwidth for verification data transmission

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Bluetooth communication serves as an intermediary channel between the two intelligent devices, enabling secure offline verification and task execution instruction transmission. This intermediary mechanism replaces the need for network-based communication during verification, reducing network bandwidth requirements while maintaining reliable communication for the payment process

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If only one party's code is verified during payment, then the verification process is simple, but payment security is reduced

Engineering Contradiction:

Improveverification process simplicityVSAvoidpayment security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The verification process is performed periodically in two distinct stages: first verification of the identification code and second verification of the task execution instruction. This periodic multi-stage verification ensures that each critical component is verified at the appropriate time, enhancing payment security while maintaining operational simplicity through clear sequential steps

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system implements feedback mechanisms where the first intelligent device verifies the task execution instruction and provides verification results back to the second intelligent device. This feedback loop ensures that both parties' codes are validated, improving payment security while maintaining ease of operation through automated verification feedback that guides the payment process

Inventive Principle:

Principle #23Feedback
