Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dedicated building automation software and technical training are required for operation, then system control capability is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvesystem control capabilityVSAvoidease of operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent uses visual codes (barcodes, QR codes, data matrices) as simplified copies of field device identifiers. Instead of requiring users to interact with complex building automation software interfaces, the system creates visual representations that can be scanned by mobile devices, translating complex device identification into a simple visual scanning operation that anyone can perform

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces mobile devices as intermediaries between users and the building automation system. The mobile device acts as a mediator that captures visual codes, transmits them to the building automation system, and relays information back to the user, eliminating the need for users to directly operate complex control software while maintaining system connectivity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If specialized control interfaces are used, then system functionality is improved, but device complexity deteriorates

Engineering Contradiction:
Improvesystem functionalityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes mobile devices universal interfaces for interacting with the building automation system. Instead of requiring specialized control panels or dedicated software installations, the system leverages the ubiquity of mobile devices to provide access to field device information and control capabilities across the entire building automation infrastructure

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

Solution Approach 2:

The system creates visual code copies of field device identifiers that can be read by any mobile device with scanning capability. This approach eliminates the need for specialized control interfaces while maintaining full system functionality, as the visual codes serve as universal keys to access and control any field device

Inventive Principle:
Principle #26Copying

AI summary

There is described a building automation system (100) comprising a communication component (304), a processor (308), and an output component (318). The communication component (304) scans the building automation system (100) to discover devices (120, 122, 124), and the processor (308) generates a visual code for a particular field device. The visual code identifies a uniform resource locator directed to a virtual node hosting environment of the building automation system (100) associated with the field device (120, 122, 124). The output component (318) produces the visual code at a physical material for exhibition in proximity to the field device (120, 122, 124). Thereafter, the hosting environment receives a status request, associated with the uniform resource locator, for the field device (120, 122, 124) from a mobile device (126). The hosting environment generates point information associated with the field device (120, 122, 124) based on information collected from the field device in response to receiving the status request. The communication component (304) sends the point information to the mobile device (126).
