Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used for lawn cutting, then operational flexibility is maintained, but labor costs increase and work efficiency becomes unstable
Solution Approach 1:
The autonomous working apparatus performs lawn mowing operations independently without human intervention. The control circuit autonomously plans paths, navigates working areas, controls cutting assemblies, and transitions between multiple working areas based on pre-stored map data, making the system self-sufficient and eliminating the need for manual operation
Solution Approach 2:
The patent replaces manual mechanical operation with an automated control system. The control circuit uses electronic control to manage the driving assembly, cutting assembly, and navigation functions, substituting human mechanical control with an automated electro-mechanical system that improves efficiency and consistency
2Reliability
If operator skill variations are present, then adaptability to different conditions exists, but cutting quality and work efficiency become unstable
Solution Approach 1:
The control circuit continuously monitors the working status and position of the autonomous apparatus, comparing actual performance with planned operations. The system uses feedback from sensors and position data to adjust navigation, cutting depth, and speed, ensuring consistent cutting quality regardless of initial conditions or environmental variations
Solution Approach 2:
The control circuit dynamically adjusts operational parameters such as cutting height, travel speed, and path planning based on real-time conditions and pre-stored map data. This automated parameter optimization ensures consistent cutting quality by eliminating human skill variation while adapting to different working area characteristics
3Productivity
If multiple working areas are serviced manually, then comprehensive coverage is achieved, but time consumption and transition inefficiency increase
Solution Approach 1:
The system pre-stores map data of multiple working areas in advance before operation begins. The control circuit has already planned the optimal paths and sequences for servicing multiple working areas, eliminating the need for on-site surveying and path planning during actual mowing operations, thus reducing transition time and improving overall productivity
Solution Approach 2:
The autonomous working apparatus maintains continuous operation by seamlessly transitioning between multiple working areas without manual intervention or significant downtime. The control circuit coordinates the driving assembly to move efficiently between areas while the cutting assembly remains ready for immediate operation, ensuring continuous useful action and minimizing idle transition time

AI summary
A mowing control process includes: acquiring map data of a first working area of a mowing task to be executed; planning a moving path of the autonomous working apparatus in the first working area at least according to the map data of the first working area, and controlling the autonomous working apparatus to autonomously traverse the first working area along the planned movement path and perform single-pass mowing in the first working area. The single-pass mowing is achieved through simultaneously mulching or collecting grass during mowing. The autonomous working apparatus switches to a state of moving or preparing to move toward a next first working area after detecting completion of traversal of the first working area.
