Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a built-in battery pack is used in the autonomous lawnmower, then the device can work automatically without manual supervision, but the battery pack cannot be manually detached and requires tools for mounting or detaching
Solution Approach 1:
The battery pack is designed as a separate, detachable module from the autonomous lawnmower body. The battery pack includes its own housing, terminals, and mounting structure, allowing it to be independently removed and replaced without tools, while the lawnmower maintains automatic operation capability when the battery is properly mounted.
2Ease of operation
If a detachable battery pack is used in electric tools, then the battery pack can be replaced with a backup, but the user has to stop work and manually charge the battery packs at home or another charging site
Solution Approach 1:
The charging station merges multiple functions into one system: it serves as both a charging device for battery packs and a docking station for the autonomous lawnmower. The lawnmower can automatically return to the charging station, dock with it, and have its battery recharged without manual intervention, ensuring continuous operation.
Solution Approach 2:
The autonomous lawnmower is equipped with automatic return and docking capabilities. When the battery needs charging, the lawnmower autonomously navigates back to the charging station, docks with it, and initiates the charging process without requiring user intervention, thereby maintaining work continuity.
3Productivity
If the autonomous lawnmower automatically returns to the charging station to charge, then the work continuity is improved, but the charging system becomes more complex with multiple charging modes and management requirements
Solution Approach 1:
The charging station is designed with universal functionality to handle multiple charging scenarios: it can charge battery packs independently, charge the autonomous lawnmower when it docks automatically, and support different battery types through a standardized charging interface and control algorithm that adapts to various energy modules.

AI summary
An automatic working system includes a self-moving device powered by an energy module and moving and working in a defined working area. The self-moving device includes a body, a movement module, a task execution module, a control module, and a charging system configured to store external electrical energy in the energy module to charge the energy module. The charging system includes at least two charging modes for charging the energy module. In the different charging modes, the charging system uses different charging logics and/or different charging parameters to charge the energy module. The charging system further includes a charging management module configured to manage the charging modes, to enable the charging system to use a corresponding charging mode to charge the energy module.
