Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If traditional IoT device registration methods are used, then device connection can be established, but the registration process is complex and time-consuming

Engineering Contradiction:

Improvedevice registration timeVSAvoidregistration process complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent introduces a tag device as an intermediary between the electronic device and the IoT device. The tag device receives basic information from the IoT device via NFC and transmits it to the electronic device via UWB, simplifying the registration process and reducing the time required for device connection.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The tag device pre-collects basic information from the IoT device (such as device ID, manufacturer, model) before the actual connection is established. This preliminary action prepares the necessary data in advance, eliminating the need for time-consuming information exchange during the connection process.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If direct device discovery methods are used, then IoT devices can be found, but the discovery process lacks efficiency and reliability

Engineering Contradiction:

Improvedevice discovery reliabilityVSAvoiddevice discovery efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The tag device serves as a reliable intermediary that guarantees the transmission of basic information from the IoT device to the electronic device. This intermediary approach ensures data accuracy and reliability while maintaining high discovery efficiency through UWB's fast communication capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The tag device is designed with multi-functionality, supporting both NFC for receiving information and UWB for transmitting information. This universal approach allows a single device to handle multiple communication protocols, improving both reliability and efficiency in the device discovery process.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple communication protocols are implemented for device connection, then connection versatility is improved, but device complexity increases

Engineering Contradiction:

Improveconnection method versatilityVSAvoidcommunication protocol complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the communication tasks into separate segments: the tag device handles NFC communication with the IoT device, while UWB communication with the electronic device. This segmentation allows each component to use optimized protocols for its specific function, maintaining versatility without increasing overall system complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The tag device acts as a mediator that translates between different communication protocols. It receives data via NFC and transmits via UWB, effectively bridging two communication systems without requiring the main electronic device to implement both protocols directly, thus maintaining versatility while controlling complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)
