Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home automation systems face limitations in flexibility and scalability, particularly in managing a large number of equipment items, due to centralized control architectures and limited addressing capabilities, which hinder efficient energy management and comfort functions in buildings.
Innovation Solution
A method for automatically configuring network addresses in a hierarchical communication network, allowing communicating elements to negotiate and propagate network prefixes, enabling flexible and scalable network configuration without operator intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a centralized control architecture with shared data bus is used, then the system structure is simple, but the flexibility and scalability are limited when managing a large number of equipment items
Solution Approach 1:
The patent divides the centralized control system into a hierarchical structure with multiple levels (centralized control units at different hierarchical levels). Each control unit manages a specific segment of equipment, allowing the system to scale by adding more control units at appropriate levels without requiring complete system redesign or recabling.
Solution Approach 2:
The patent introduces hierarchical levels as an additional dimension to the network architecture. Instead of a single flat layer, the system organizes control units across multiple hierarchical levels, enabling scalable management of large numbers of equipment items by distributing control functions across these levels.
2Ease of operation
If manual operator intervention is used for network address configuration, then the configuration process is simple for small networks, but the installation and update costs increase for large-scale deployments
Solution Approach 1:
The patent enables communicating elements to automatically configure their own network addresses through negotiation with control units. Each element autonomously determines its address based on information exchanged during the connection process, eliminating the need for manual operator intervention and significantly improving installation efficiency for large-scale deployments.
Solution Approach 2:
The patent implements automatic network address configuration that occurs during the initial connection and negotiation phase. The addressing information is predetermined and automatically assigned through protocol exchange, so that when equipment is connected, its network address is already configured without requiring subsequent manual intervention.
3Device complexity
If centralized control architecture is used, then the system architecture is simplified, but communication lag time increases as information must escalate to the control unit for processing
Solution Approach 1:
The patent segments the centralized control function across multiple control units at different hierarchical levels. This allows communication to be handled locally at appropriate hierarchical levels rather than requiring all information to escalate to a single central control unit, thereby reducing communication lag time while maintaining architectural simplicity.

AI summary
Disclosed is a method for automatically configuring a network address of network interfaces of communicating elements intended to form part of a home-automation system for a building and belonging to an unconfigured network part, the unconfigured network part including a head network equipment item and at least one communicating element, the network address of each network interface including a network prefix. The method is implemented subsequent to the connection of the head network equipment item to a configured communication network arranged in the form of a hierarchical network including at least two successive hierarchy levels, the method including steps of: negotiating the network prefix of the network interface of the head network equipment item; propagating the network prefix to the communicating elements belonging to the network part with a view to the automatic configuration of the network addresses of the set of network interfaces of the communicating elements.
