Solution Overview

Problem

Existing building automation systems face challenges in network security and user customization, as they require labor-intensive programming and lack effective methods for personalized environmental control settings, especially in large commercial and industrial facilities.

Innovation Solution

A network-independent interface approach using a mobile computing device to generate and read machine-readable codes, such as QR codes, which allows users to set and adjust environmental settings without a network connection, enabling secure and customizable control of building automation systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If networked or smart switches and thermostats are used to allow users to adjust environmental settings, then user control and customization are improved, but network security risks and system complexity increase

Engineering Contradiction:
Improveuser controlVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the configuration and authentication data from the networked system and embeds it directly into a machine-readable code (QR code) that can be read by a code reader device. This removes the need for complex network programming while maintaining user control capabilities, as users can simply scan the code to configure their environmental settings without navigating complex network protocols or authentication sequences.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a machine-readable code as an intermediary between the building automation system and the user's mobile device. Instead of direct network communication requiring complex programming, the QR code serves as a simple mediator that transfers configuration and authentication data, greatly simplifying the user interface while maintaining system security and functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If traditional thermostats and switches with physical locks are used, then security is improved, but ease of operation and user customization are reduced

Engineering Contradiction:
ImprovesecurityVSAvoiduser customization
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical lock system on traditional thermostats with an electronic authentication mechanism delivered through a machine-readable code. Instead of physical locks that prevent access, the system uses digitally encoded authentication data that can be easily verified, maintaining security while allowing authorized users to customize their environmental settings through simple code scanning rather than physical manipulation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If labor-intensive programming is used for initial configuration, then system security and control precision are improved, but time consumption and operational complexity increase

Engineering Contradiction:
Improvecontrol precisionVSAvoidconfiguration time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs the complex authentication and configuration actions in advance by encoding all necessary data into a machine-readable code during system setup. When a user needs to customize their environment, they simply scan the pre-prepared QR code which instantly provides all configuration data, eliminating the need for time-consuming on-site programming while maintaining precise control over environmental parameters.

Inventive Principle:
Principle #10Preliminary action

4Stability of the object's composition

If centralized control stations are used to monitor and control dispersed system elements, then system coordination is improved, but network dependency and system complexity increase

Engineering Contradiction:
Improvesystem coordinationVSAvoidnetwork complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent segments the centralized control function by distributing machine-readable codes to multiple locations throughout the building. Each code contains localized configuration and authentication data that can be independently scanned and executed, allowing dispersed control elements to maintain coordination without requiring continuous network communication or complex centralized management, thus reducing network dependency while preserving system stability.

Inventive Principle:
Principle #1Segmentation
