Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a replacement HVAC controller with different wiring requirements is selected, then the user can access newer features and improved functionality, but the complexity of determining the correct wiring configuration increases significantly
Solution Approach 1:
The patent introduces an intermediary system consisting of a camera, image processing algorithms, and a user interface that mediates between the user and the complex wiring configuration task. The camera captures images of the old thermostat wiring, the system processes these images to identify wire connections, and presents the new wiring configuration through an intuitive interface, thereby shielding the user from the underlying complexity.
Solution Approach 2:
The system enables self-service by allowing the replacement HVAC controller to automatically capture its own wiring configuration information through an integrated camera, process the images to identify terminal connections, and generate wiring instructions without requiring external assistance or complex manual input from the user.
2Ease of manufacture
If manual wiring identification methods are used, then the system requires no additional components, but the ease of operation deteriorates due to the numerous possible configurations and user expertise requirements
Solution Approach 1:
The patent replaces manual mechanical inspection and identification methods with an automated optical system. Instead of requiring users to physically trace wires and manually interpret wiring diagrams, the system uses a camera to capture images and automated image processing to identify connections, substituting mechanical user actions with automated visual recognition.
Solution Approach 2:
The system creates a visual copy of the existing wiring configuration by capturing an image of the old thermostat terminals and wire connections. This copy is then processed to extract wiring information and presented in a format suitable for the new controller, eliminating the need for users to manually record or interpret wiring details.
3Ease of manufacture
If traditional wiring documentation methods are used, then no additional hardware is needed, but the loss of information increases due to user errors in transcribing or interpreting wiring configurations
Solution Approach 1:
The system creates an accurate digital copy of the wiring configuration by capturing an image of the physical wiring and using image processing to extract terminal labels and wire connections. This digital copy eliminates transcription errors and ensures accurate transfer of wiring information from the old to the new controller.
Solution Approach 2:
The system incorporates feedback mechanisms where the captured image and processed wiring information are displayed to the user for verification. This allows users to confirm that the system has correctly identified the wiring configuration before proceeding, reducing information loss and enabling correction of any identification errors.

AI summary
A wiring configuration tool may be configured to determine a new wiring configuration for a replacement HVAC controller based, at least in part, on the existing wiring configuration for a current HVAC controller and, for example, the make and model of the replacement HVAC controller. The wiring configuration tool may be hosted by a server that provides a user interface for interacting with the user. The user may access the wiring configuration tool via a web services interface, a smart phone application or in any other suitable manner.
