Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for updating firmware or software in electric motors are time-consuming and risky, as they require physical connection to a power source and another device for downloading updates, which can lead to damage or mishandling during the process.
Innovation Solution
A motor controller with a motion control microcontroller unit (MCU) and a wireless receiver that can be powered by an energy management system, allowing for wireless reprogramming without an external power source, enabling simultaneous and parallel updates of multiple motors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connection and external power source are used for firmware updates, then update reliability is improved, but update time and operational complexity increase significantly
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The motor controller uses wireless communication modules to receive firmware updates and control signals without physical cable connections, eliminating the time-consuming process of plugging and unplugging cables while maintaining reliable data transmission through standardized wireless protocols.
Solution Approach 2:
The patent implements preliminary action by enabling the motor controller to operate autonomously on its internal power source before connecting to external power. This allows firmware updates to be initiated and completed in advance during storage or transportation, so that when the motor is installed and connected to external power, the updates are already applied and the system is ready for immediate operation.
2Reliability
If wired connection is used for firmware updates, then power stability is improved, but risk of damage and operational complexity increase
Solution Approach 1:
The motor controller is equipped with an internal power source (such as a battery or energy storage device) that enables it to perform self-updates without external power connection. The controller can autonomously manage its power consumption during the update process, activating wireless receivers and processing firmware independently, thereby eliminating the risk of power-related damage from external connections.
Solution Approach 2:
The patent extracts the power supply function from the external power source and relocates it to an internal power source within the motor controller. This separation allows the update process to be independent of external power connections, removing the harmful factor of potential power instability or electrical damage from the update operation.
3Manufacturing precision
If individual motor updates are performed with wired connections, then update accuracy is maintained, but productivity and efficiency decrease
Solution Approach 1:
The patent implements multi-functionality by enabling a single wireless communication module to serve multiple motors simultaneously. The system can broadcast firmware updates to multiple motor controllers in the same environment, allowing parallel updates across multiple devices without requiring individual wired connections for each motor, thereby significantly improving productivity while maintaining update accuracy through standardized wireless communication protocols.

AI summary
A motor controller for controlling an electric motor includes a motion control microcontroller unit (MCU) for storing initial control parameters for the electric motor, and a wireless receiver communicatively coupled to the motion control MCU. The wireless receiver is configured to activate in response to initiation of a wireless connection with a remote device, receive a wireless control signal from the remote device, the wireless control signal including updated control parameters, and transmit the updated control parameters to the motion control MCU. The motor controller also includes an energy management system configured to power the wireless receiver and the motion control MCU.
