Solution Overview

Problem

In existing home network management systems, all home network devices must support a remote management protocol for a remote service device to access them, which is not feasible if the existing network is not significantly altered.

Innovation Solution

A home network access device establishes a data model of each home network device using information obtained through a home network protocol, allowing a remote service device to access this data model via a remote management protocol, eliminating the need for all devices to support the remote management protocol.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If all home network devices support the remote management protocol for direct access, then the remote service device can directly manage home network devices, but the device complexity and network modification requirements increase significantly

Engineering Contradiction:
Improveremote management capabilityVSAvoidprotocol support requirement
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The home network access device serves as an intermediary between the remote service device and home network devices. It establishes a data model of home network devices and communicates with the remote service device using the remote management protocol, while communicating with home network devices using their native home network protocol, thus eliminating the need for home network devices to support the remote management protocol directly

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The home network access device creates a data model that replicates the structure and information of home network devices. This data model allows the remote service device to interact with a simplified representation of the actual devices, reducing the complexity requirements for the physical home network devices while maintaining full remote management functionality

Inventive Principle:
Principle #26Copying

2Reliability

If existing home network devices are modified to support the remote management protocol, then remote access becomes possible, but the ease of operation and network compatibility decrease

Engineering Contradiction:
Improveremote access capabilityVSAvoidnetwork compatibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The home network access device acts as a protocol translation intermediary. It receives remote management protocol messages from the remote service device, translates them into appropriate home network protocol messages, and forwards them to the target home network devices. This approach maintains compatibility with existing home network devices while enabling remote access functionality

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a unified interface is implemented for remote management, then the remote service device can access home network devices through a single point, but the device complexity of the gateway increases

Engineering Contradiction:
Improveunified access interfaceVSAvoidgateway functionality
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The home network access device implements a universal data model structure that can represent multiple types of home network devices through a consistent interface. This data model includes standardized elements such as device information objects, service information objects, and action information objects, allowing the gateway to provide unified remote management access to diverse devices without requiring complex device-specific handling logic

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