Universal Blower Motor Controller Using Removable Parameter Memory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating and cooling systems require specific controllers for different sizes and types, leading to the need for multiple controllers, which is inefficient and problematic when a universal solution is needed.
Innovation Solution
A universal system controller with a communication means and removable memory device that identifies and configures blower motor parameters, allowing it to operate various heating and cooling systems by retrieving specific motor-related parameters and sending them to the blower motor controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple specific controllers are used for different heating and cooling system sizes and types, then each system can be controlled precisely, but the number of controllers increases and system complexity increases
Solution Approach 1:
The patent implements a universal controller that can control multiple types of heating and cooling systems through configurable parameters stored in memory. The controller adapts to different system configurations by retrieving appropriate parameter sets, eliminating the need for multiple dedicated controllers while maintaining precise control for each system type
2Adaptability or versatility
If a universal controller is designed to accommodate various system configurations, then the number of controllers is reduced, but the controller complexity and programming requirements increase
Solution Approach 1:
The patent stores pre-configured parameter sets in memory before the controller is deployed. Each parameter set corresponds to a specific heating or cooling system configuration, allowing the universal controller to adapt to different systems by simply retrieving the appropriate pre-programmed parameters without requiring complex real-time programming or configuration
3Reliability
If system-specific controllers are used for each heating or cooling system configuration, then optimal performance is achieved, but replacement and maintenance become more difficult
Solution Approach 1:
The universal controller design allows any controller to replace any other controller in the system. Since all controllers use the same hardware platform and communicate through standardized protocols, replacement is simplified to a straightforward swap operation. The system parameters are stored in memory and can be reconfigured as needed, eliminating the need for specialized knowledge for each controller type

AI summary
A system controller is provided that includes a communication network for transmitting and receiving information from an installed blower motor controller, and a removable memory device connected to the system controller. The removable memory device includes stored system parameter information related to a particular heating or cooling system, which information includes at least motor related parameters related to one or more types of blower motors. The system controller further includes a processor that receives, via the communication network, identifying information from the blower motor controller that identifies the type of blower motor that is installed. The processor is configured to retrieve motor related parameters corresponding to the specific identified blower motor from the memory device, and to send the corresponding motor related parameters to the blower motor controller.
