Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple signal interfaces are employed to support various control systems, then the adaptability of the motor controller is improved, but the device complexity increases due to multiple electric isolations and complicated circuits
Solution Approach 1:
The patent implements a universal mother circuit board with standardized interface design that can accommodate multiple control systems through a unified communication protocol. The board integrates multiple electric isolation functions and signal processing capabilities into a single standardized platform, allowing different control systems to interface through the same physical and logical interface structure, thereby reducing overall system complexity while maintaining broad adaptability
Solution Approach 2:
The invention introduces a standardized interface layer as an intermediary between the motor controller and various control systems. This interface board translates and mediates signals from different control systems into a unified internal format, eliminating the need for multiple specialized interfaces and their associated complex isolation circuits, thus resolving the contradiction between adaptability and complexity
2Adaptability or versatility
If multiple daughter circuit boards with different interface circuit units are used to support various control systems, then the adaptability is improved, but the ease of manufacture deteriorates due to excessive types requiring management and development
Solution Approach 1:
The patent employs a universal mother circuit board design with standardized connectors, signal protocols, and isolation architectures that can support multiple control system interfaces through a single platform. This eliminates the need to manufacture and manage multiple specialized daughter circuit boards, as all interface requirements are fulfilled by the standardized mother board, thereby significantly improving ease of manufacture while preserving adaptability
Solution Approach 2:
The invention merges the functions of multiple specialized daughter circuit boards into a single integrated mother circuit board with standardized interfaces. By combining various interface circuit units, isolation circuits, and signal processing functions into one unified design, the system reduces the number of separate components that need to be manufactured, inventoried, and assembled, thus enhancing manufacturing efficiency
3Adaptability or versatility
If conventional motor development is performed for each specific control system, then the adaptability to specific applications is improved, but the productivity deteriorates due to time-consuming development and increased production costs
Solution Approach 1:
The patent implements a universal motor controller platform with standardized circuit boards and interfaces that can be applied across multiple control systems and applications. This standardized platform eliminates the need for separate development cycles for each control system, as the same hardware platform can accommodate different interfaces through software or configuration changes, thereby dramatically improving productivity while maintaining adaptability
Solution Approach 2:
The invention segments the motor controller into modular components with a standardized core (mother circuit board) and configurable interface layers. This segmentation allows the core functionality to be developed once and reused across multiple applications, while only the interface configuration needs to be adapted for different control systems, thus reducing development time and improving productivity
