Solution Overview

Problem

Intelligent hosts with WIFI and Ethernet communication modes have different MAC addresses when connected to the cloud, leading to the same device being registered as two different devices due to different communication methods, causing inconvenience in information management.

Innovation Solution

A MAC address synchronization method that involves an intelligent terminal acquiring the MAC address of the WIFI module, sending it to the control module, and writing it to the Ethernet module, ensuring both modules have the same address for unified cloud registration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the smart host uses different communication modes (WIFI and Ethernet), then it can access the cloud through multiple ways, but it will be registered as two different devices due to different MAC addresses

Engineering Contradiction:

Improvecommunication modeVSAvoiddevice identity consistency

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The control module acts as an intermediary that manages and synchronizes the MAC address across different communication modules. It receives the MAC address from the WIFI module and writes it to the Ethernet module, ensuring both modules use the same MAC address for cloud registration, thus maintaining device identity consistency while supporting multiple communication modes

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The Ethernet module is made multi-functional by enabling it to use the same MAC address as the WIFI module. This allows the Ethernet module to not only provide wired network connectivity but also maintain consistent device identity for cloud registration, achieving universal device identification across different communication interfaces

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If the WIFI module and Ethernet module have different MAC addresses, then each can operate independently, but the same smart host is registered as two different devices causing management inconvenience

Engineering Contradiction:

Improveindependent operationVSAvoiddevice information management

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent merges the MAC address functionality of the WIFI module and Ethernet module by making them share the same MAC address. The control module copies the MAC address from the WIFI module to the Ethernet module, ensuring both modules present the same device identity to the cloud, thus simplifying device information management while maintaining independent operational capability

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The invention discloses a MAC address synchronization method for synchronizing a MAC address of a WIFI module and an Ethernet module on a smart host, comprising the intelligent terminal acquires the MAC address of the WIFI module; the intelligent terminal sends the obtained MAC address to the control module through the WIFI module; the control module writes the received MAC address to the Ethernet module. The invention makes the Ethernet module have the same MAC address as the WIFI module. When the smart host accesses the cloud through the WIFI and the Ethernet respectively, the WIFI module and the Ethernet module have the same MAC address.
