Innovation Solution
A modular motor controller design featuring a mother circuit board with a controlling and processing unit and a daughter circuit board with an identifying circuit, allowing automatic configuration of input/output ports, enabling the same motor controller to be adapted for different user-end systems by swapping daughter circuit boards, thus reducing the number of motor types and simplifying production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional motor controller is developed for each user-end control system, then the controller can be specifically optimized for that system, but the development cost, development time, and management complexity increase significantly
Solution Approach 1:
The patent implements a universal motor controller platform that can serve multiple user-end control systems through a standardized interface circuit unit. The controller includes a mother circuit board with core control functions and a daughter circuit board with configurable interface circuits that can be adjusted via identifying signals. This allows a single motor controller design to adapt to different control systems (e.g., air-conditioner, washing-machine) without requiring separate development for each application, thereby reducing the number of motor controller types while maintaining broad adaptability.
Solution Approach 2:
The patent employs dynamic configuration of the interface circuit unit based on identifying signals. The controlling and processing unit automatically configures the interface circuit unit according to the identified user-end control system type, enabling the controller to dynamically adapt its behavior and interface characteristics. This dynamic adjustment mechanism allows the same hardware platform to serve multiple purposes without physical reconfiguration or redesign.
2Adaptability or versatility
If separate motor controllers are developed for different user-end control systems, then each controller can be optimized for its specific application, but the development cycle and time consumption increase
Solution Approach 1:
The patent establishes a pre-configured universal platform with standardized interface circuit units that can be quickly adapted to different applications. The mother circuit board contains pre-developed core control functions, and the daughter circuit board includes interface circuits that can be configured through identifying signals. This preliminary preparation of a versatile platform eliminates the need for time-consuming redevelopment for each new application, significantly shortening the development cycle while maintaining application-specific optimization capabilities.
3Adaptability or versatility
If multiple motor types are maintained for different manufacturers and applications, then each motor can be optimized for its specific use, but management becomes inconvenient and costs increase
Solution Approach 1:
The patent creates a standardized universal motor controller platform with consistent core architecture, control algorithms, and interface standards. The mother circuit board implements unified control logic, and the daughter circuit board provides standardized interface configurations that can be adapted through identifying signals. This standardization enables centralized management of motor controllers across different manufacturers and applications, reducing the number of distinct motor types while maintaining the ability to optimize for specific uses through configuration rather than redesign.
4Adaptability or versatility
If new production techniques are developed for each motor type, then each motor can be manufactured with optimal processes, but the production complexity and authentication costs increase
Solution Approach 1:
The patent segments the motor controller into modular components: a mother circuit board with standardized core functions and daughter circuit boards with application-specific interface circuits. This segmentation allows the majority of the controller (mother board) to be manufactured using a single standardized production process, while only the smaller daughter circuit boards require application-specific configuration. This modular approach simplifies production techniques and reduces authentication costs compared to developing entirely new production processes for each motor type.
