Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional wiring systems are used for EC windows, then power and control can be delivered to the windows, but the wiring complexity and installation difficulty increase significantly
Solution Approach 1:
The patent replaces the mechanical wiring system with a wireless communication and power delivery system. Controllers communicate with EC windows and deliver power wirelessly, eliminating the need for complex physical wiring infrastructure while maintaining full control and power delivery capabilities.
Solution Approach 2:
The patent enables EC windows to self-configure and self-integrate into the building network automatically. Controllers automatically detect and register new windows, assign addresses, and establish communication without manual wiring configuration, dramatically simplifying installation.
2Adaptability or versatility
If EC windows are integrated into building structures, then functional control is achieved, but the wiring infrastructure requirements increase
Solution Approach 1:
The patent substitutes traditional electrical wiring infrastructure with wireless communication and power delivery systems. This allows EC windows to be integrated into building structures without requiring预埋 wiring conduits or electrical infrastructure modifications.
Solution Approach 2:
The patent creates a universal controller platform that can work with any EC window regardless of location or configuration. The wireless system provides universal compatibility across different building types and window placements without requiring location-specific wiring infrastructure.
3Ease of operation
If controllers are installed separately from windows, then control functionality is provided, but matching and installation complexity increase
Solution Approach 1:
The patent merges the controller and EC window into a single integrated unit. The controller is incorporated within or directly attached to the window assembly, eliminating the need for separate installation and matching procedures while maintaining full control functionality.
Solution Approach 2:
The patent performs controller-window pairing and configuration in advance during manufacturing. Controllers are pre-configured and tested with their corresponding windows before delivery, eliminating field matching complexity and ensuring immediate operational readiness upon installation.

AI summary
Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations. Also described are self-meshing networks for electrochromic windows.
