Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-organization networks for smart control in multiple zones of a building require manual configuration of wireless nodes to connect with zone controllers, consuming significant human resources and time.
Innovation Solution
A method where zone controllers establish a connection, designate a head zone controller to enable joining-permitted functions, and generate configuration messages for wireless nodes to automatically connect to the best available controller network, eliminating the need for manual setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual configuration is used to connect wireless nodes to zone controllers, then connection accuracy is improved, but human resource cost and time cost increase
Solution Approach 1:
The patent applies preliminary action by having zone controllers pre-establish connections and generate configuration messages before wireless nodes need to connect. The ZC-head collects node data, generates configuration messages with optimal ZC assignments, and distributes them in advance, so nodes can automatically connect without manual configuration during deployment.
Solution Approach 2:
The patent implements self-service through automatic connection establishment where wireless nodes autonomously search for and connect to their assigned zone controllers using configuration messages. The system self-configures without human intervention, with nodes independently joining the network based on pre-generated configuration data from the ZC-head.
2Measurement precision
If manual configuration is used to connect wireless nodes to zone controllers, then connection accuracy is improved, but operation complexity increases
Solution Approach 1:
The system enables self-service by allowing wireless nodes to automatically connect to zone controllers using configuration messages. The manual configuration process is completely eliminated, as nodes autonomously search for their assigned ZCs and join the network without human intervention, significantly simplifying operation.
Solution Approach 2:
The patent applies preliminary action by pre-generating configuration messages that contain assignment information before deployment. This preliminary configuration generation by the ZC-head eliminates the need for operators to perform complex manual configuration tasks during installation and setup.
3Ease of operation
If automatic connection is implemented without manual configuration, then operation complexity is reduced, but connection accuracy may deteriorate
Solution Approach 1:
The patent implements feedback through a two-stage connection process. First, nodes connect automatically using configuration messages for initial assignment. Then, nodes can search for better-matched ZCs based on actual signal quality and performance feedback, ensuring both automation and connection accuracy are maintained.
Solution Approach 2:
The system uses preliminary action by pre-generating configuration messages with optimal ZC assignments based on collected node data before deployment. This preliminary configuration ensures accurate initial connections, while the subsequent re-search mechanism allows nodes to optimize their connections based on actual performance feedback.

AI summary
A self-organization network establishing method comprising following steps is presented. A plurality of zone controllers (ZCs) establishes a connection, and one of the ZCs is chosen as a ZC-head. The ZC-head instructs the ZCs to enable a joining-permitted function. A plurality of wireless nodes respectively searches for one of the ZCs to join to a corresponding controller network thereof after the ZCs enable the joining-permitted function. The ZC-head collects data of the wireless nodes through the ZCs, and generates configuration messages for each wireless node based on the collected data. The ZCs disconnect all network connections after the collection is completed. Finally, each wireless node respectively re-searches for their best ZC to join to the corresponding controller network thereof according to the configuration messages.
