Innovation Solution

A method and apparatus for automatically determining and enabling a target transmission function between devices based on priority, using connection information that includes transmission functions and authentication details, allowing devices to establish a connection through the most suitable function.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If NFC technology is used for file transmission, then authentication between devices is achieved, but transmission rate is low and transmission distance is limited

Engineering Contradiction:
Improveauthentication reliabilityVSAvoidtransmission rate
Core Design Contradiction:
ReliabilityVSSpeed

Solution Approach 1:

The patent segments the transmission process into two stages: NFC-based authentication stage (for security verification) and wireless transmission stage (for actual data transfer). This allows the system to leverage the security strengths of NFC while overcoming its speed limitations by using alternative wireless protocols for the data transmission phase.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary mechanism where NFC serves as a mediator for authentication, and then triggers the establishment of a secondary communication channel (such as Wi-Fi Direct or Bluetooth) for actual data transfer. This intermediary approach allows seamless transition between authentication and transmission functions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a specific transmission function is enabled through NFC protocol, then connection establishment is automated, but data transmission fails when one device lacks the specified function

Engineering Contradiction:
Improveconnection establishment automationVSAvoiddata transmission reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent dynamically changes the transmission function parameter based on device capabilities. Instead of being fixed to a single protocol, the system detects available transmission functions (Wi-Fi, Bluetooth, etc.) and selects the most suitable one, thereby maintaining automation while improving reliability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent makes the connection establishment mechanism universal by supporting multiple transmission functions (Wi-Fi Direct, Bluetooth, etc.) rather than being tied to a single NFC protocol. This multi-functionality ensures that devices can establish connections even when specific transmission functions are not available on all devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If multiple transmission functions are supported by devices, then transmission reliability improves, but device complexity increases

Engineering Contradiction:
Improvetransmission reliabilityVSAvoidtransmission function configuration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service by having the system automatically detect available transmission functions and select the appropriate one without user intervention. The device autonomously manages the complexity of multiple protocols, reducing the burden on users while maintaining high transmission reliability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent performs preliminary detection and configuration of transmission functions before actual data transfer. By pre-identifying available protocols and establishing connection parameters in advance, the system simplifies the overall process for users while ensuring reliable transmission.

Inventive Principle:
Principle #10Preliminary action
