Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional control systems are used in electric mowers, then the device complexity is low and ease of manufacture is good, but the degree of intelligence and information processing capability is insufficient
Solution Approach 1:
The control system is segmented into multiple independent control modules (traveling control module, mowing control module, energy source control module, instrument display module, sensor module), each responsible for specific functions. This modular architecture enables high intelligence and information processing capability while maintaining manageable complexity through clear functional separation and standardized CAN bus communication interfaces.
2Productivity
If more electronic devices and control modules are added to improve mowing capacity and efficiency, then the information processing demand increases, but the existing technology cannot satisfy the interaction of large amounts of information
Solution Approach 1:
The CAN bus serves as an intermediary communication network connecting all control modules. It enables efficient information exchange and coordination between the traveling control module, mowing control module, energy source control module, instrument display module, and sensor module, thereby supporting high productivity while maintaining complete information interaction capability across the system.
3Loss of information
If a CAN-bus-based electrical control system is implemented, then the information processing efficiency and intelligence are enhanced, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The system employs universal CAN bus communication protocols and standardized module interfaces that enable multi-functional control modules to be integrated into a unified architecture. This universality allows the system to achieve high information processing efficiency and intelligence while simplifying manufacturing through standardized components and assembly procedures rather than increasing complexity.
