A gateway with a mac layer that supports multiple communication protocols unifies data packets into a target format, allowing devices with different protocols to communicate through a unified link layer without distinguishing protocols at the upper layers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different communication protocols are used by smart home devices from different manufacturers, then device functionality and protocol optimization are improved, but intercommunication capability deteriorates

Engineering Contradiction:
Improvedevice functionalityVSAvoidintercommunication capability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces a gateway as an intermediary device that receives data packets from smart home devices using different communication protocols, unifies them into a standard format, and forwards them to a server. This mediator approach allows devices with different protocols to communicate without modifying the devices themselves, resolving the intercommunication problem while preserving protocol-specific optimizations.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the communication system into three independent parts: the device layer (using various protocols), the gateway layer (protocol translation and unification), and the server layer (standardized data processing). This segmentation allows each layer to operate independently with its own optimizations while ensuring overall system compatibility.

Inventive Principle:
Principle #1Segmentation

2Productivity

If protocol-specific processing is implemented at upper layers, then protocol optimization is improved, but system complexity increases

Engineering Contradiction:
Improveprotocol optimizationVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts the protocol translation and unification functionality from the upper layers and places it in the gateway at the lower layer. This extraction allows the upper layers to work with unified standard data formats without dealing with protocol-specific complexities, reducing system complexity while maintaining protocol optimizations at the gateway level.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent adds a new dimension to the system architecture by introducing the gateway as an intermediate layer between devices and the server. This dimensional addition separates protocol-specific processing from protocol-agnostic processing, allowing optimizations in one dimension without increasing complexity in another.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If high-performance chips are used to handle multiple protocols, then intercommunication capability is improved, but cost increases

Engineering Contradiction:
Improveintercommunication capabilityVSAvoidcost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The gateway serves as a cost-effective intermediary that consolidates the complexity of handling multiple protocols in a single device rather than requiring every smart home device to have high-performance chips. This approach improves intercommunication capability while controlling costs by centralizing the expensive functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The gateway is designed as a universal device that can handle multiple communication protocols simultaneously, making it a multi-functional solution that replaces the need for expensive protocol-handling capabilities in each individual smart home device, thereby reducing overall system cost.

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