Wireless Motor Interface Module for HVAC Configuration Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motors in HVAC systems often require specific programming that is lost when they are replaced, leading to improper function if the new motor does not share the same configuration and operation characteristics as the original, necessitating costly reprogramming at the manufacturing facility or assembly plant.
Innovation Solution
An interface module with a processor and memory that wirelessly receives configuration data from a device, determines operating parameters based on signals from a thermostat and system controller, and controls the motor accordingly, allowing for seamless integration of replacement motors into existing HVAC systems without the need for onboard user interfaces or reprogramming at the manufacturing facility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motors are replaced with new ones, then the HVAC system can continue to operate, but the new motors lack the specific configuration data and may not function properly
Solution Approach 1:
The system performs preliminary action by automatically retrieving and storing configuration data from the HVAC controller before the motor is replaced, so that when the new motor is installed, the configuration data is already available and the motor can be properly configured without manual reprogramming
Solution Approach 2:
The system creates a copy of the configuration data from the HVAC controller and transfers it to the replacement motor, allowing the new motor to replicate the operational characteristics of the original motor without requiring reprogramming at the manufacturing facility
2Ease of manufacture
If motors are programmed at the manufacturing facility, then they have specific configuration data, but replacement motors require costly reprogramming or specialized equipment
Solution Approach 1:
The system enables self-service by allowing the HVAC controller to automatically provide configuration data to replacement motors without requiring specialized programming equipment or expertise, making the configuration process as simple as connecting the motor to the controller
Solution Approach 2:
The system achieves universality by designing a configuration process that works with any standard motor replacement, eliminating the need for motor-specific programming equipment or specialized knowledge, and allowing any technician to configure a replacement motor using the existing HVAC controller
3Adaptability or versatility
If motors are configured for specific applications, then they meet system requirements, but replacement motors must share exact configuration characteristics to function properly
Solution Approach 1:
The system performs preliminary action by retrieving the specific configuration data from the HVAC controller before motor replacement, ensuring that the replacement motor will be configured with the exact parameters needed for proper system operation
Solution Approach 2:
The system uses feedback from the HVAC controller to automatically determine the correct configuration parameters for the replacement motor, ensuring compatibility with the specific HVAC system requirements without requiring manual configuration or guesswork
