A window control system configured to communicate via an application programming interface (API) with other systems, allowing for data exchange and control of optically switchable windows, enabling integrated management of building infrastructure through a network of window controllers and sensors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If smart window systems are widely deployed, then building energy efficiency and user comfort are improved, but system complexity and difficulty of managing interactions between multiple building systems increase

Engineering Contradiction:
Improvebuilding energy efficiencyVSAvoidsystem interaction management
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a gateway device as an intermediary that mediates communications between the window control system and other building systems (HVAC, lighting, security). The gateway translates messages between different protocols and formats, enabling seamless integration without direct complex point-to-point connections between all systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The gateway device serves multiple functions: it acts as a protocol translator, a message router, a data formatter, and a coordination hub. This multi-functional approach consolidates what would otherwise require multiple separate components, reducing overall system complexity while maintaining comprehensive inter-system communication capabilities.

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

2Adaptability or versatility

If multiple building systems interact with smart windows, then functionality and user comfort are enhanced, but control and monitoring sophistication requirements increase

Engineering Contradiction:
Improvesystem functionalityVSAvoidcontrol and monitoring sophistication
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The gateway serves as a centralized intermediary that handles all coordination logic between multiple building systems and the window control system. This centralization of control sophistication in the gateway protects individual systems from needing to implement complex interaction logic, allowing each to remain relatively simple while achieving sophisticated overall behavior.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback mechanisms where the gateway monitors communications and system states, translating and routing information back to appropriate systems. This feedback loop enables sophisticated coordinated control while maintaining simple individual system designs, as each system responds to standardized feedback from the gateway rather than managing complex multi-system state.

Inventive Principle:
Principle #23Feedback

3Loss of information

If window control system communicates with multiple other systems via API, then data exchange and integrated management are improved, but communication protocol compatibility challenges increase

Engineering Contradiction:
Improvedata exchange capabilityVSAvoidprotocol compatibility
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The gateway acts as a protocol translation intermediary, receiving messages from the window control system in one format and translating them into appropriate formats for target systems (HVAC, lighting, security). This eliminates the need for direct protocol compatibility between all systems, as the gateway handles format conversion centrally.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The gateway dynamically changes message parameters including protocol type, data format, address structure, and communication timing based on the target system. This parameter transformation capability enables universal communication across diverse systems without requiring each system to support multiple protocols natively.

Inventive Principle:
Principle #35Parameter changes

AI summary

Disclosed are platforms for communicating among one or more otherwise independent systems involved in controlling functions of buildings or other sites having switchable optical devices deployed therein. Such independent systems include a window control system and one or more other independent systems such as systems that control residential home products (e.g., thermostats, smoke alarms, etc.), HVAC systems, security systems, lighting control systems, and the like. Together the systems control and/or monitor multiple features and/or products, including switchable windows and other infrastructure of a site, which may be a commercial, residential, or public site.
