Solution Overview

Problem

Existing building automation systems face challenges in wireless communication binding, particularly when building automation components lack assigned addresses, leading to failed communications and inefficiencies in wireless networks.

Innovation Solution

The implementation of wireless transceivers that query and bind with building automation components for their addresses, allowing for automatic recognition and transmission of component addresses, enabling effective wireless communication by distinguishing between wired and wireless connections and managing binding through transceivers, which can request and respond to address queries to establish and maintain connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If wireless transceivers are used to replace wired connections in building automation systems, then wiring costs are reduced and installation flexibility is improved, but communication reliability deteriorates due to binding failures when components lack assigned addresses

Engineering Contradiction:

Improvewiring cost reductionVSAvoidcommunication reliability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The system enables components to automatically query and obtain their own addresses through the transceiver without manual assignment. The transceiver queries the component, receives the address, and automatically establishes the binding relationship, allowing the system to self-configure and eliminate manual address assignment requirements.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The transceiver performs preliminary address querying and binding establishment before actual communication operations. By pre-obtaining the component address and establishing the binding relationship in advance, the system ensures communication reliability is set up beforehand, preventing binding failures during operation.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If manual address assignment is used during installation, then communication binding is established, but installation time increases and automation is reduced

Engineering Contradiction:

Improvebinding establishmentVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Components automatically provide their addresses when queried by the transceiver during installation, eliminating the need for manual address assignment. The system self-configures the binding relationship through automated address querying and recognition, significantly reducing installation time while maintaining binding reliability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical process of address assignment is replaced with an automated electronic querying system. The transceiver electronically queries the component to obtain its address automatically, substituting the manual mechanical assignment process with an automated electronic information exchange process.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Area of stationary object

If transceivers transmit all communications wirelessly, then wireless network coverage is maximized, but traffic overlap and interference increase

Engineering Contradiction:

Improvewireless network coverageVSAvoidtraffic overlap

Core Design Contradiction:

Area of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The system differentiates between wired and wireless connection types for different components, applying appropriate transmission methods locally. Transceivers identify whether a component is connected via wire or wireless and adjust transmission accordingly, minimizing wireless traffic for wired components while maintaining wireless coverage for wireless components.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Instead of transmitting all communications wirelessly, the system selectively transmits only necessary communications wirelessly. By identifying wired connections and restricting their traffic to wired channels, the system reduces overall wireless traffic volume and minimizes traffic overlap and interference while maintaining adequate wireless coverage.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Wireless transceivers connect with or in building automation components. The components are bound. Since the transceivers control the access media, the transceivers are likewise bound. The transceiver associated with a component queries the component for the component address. When a request from a controller addressed to the component is received, the transceiver for the component may recognize the component address. In response, the transceiver records the controller transceiver address in the request and transmits a response with the component transceiver address. Other features may assist in binding. For example, the controller transceiver distinguishes between components connected by wire from wireless. Only communications for wireless connections are transmitted. For example, if a binding is not used for an amount of time, the binding is removed. For example, a random or set order is used to avoid or minimize overlapping traffic for the responses for a binding list.
