Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple different batteries are used for different applications and power levels, then the power supply capacity is sufficient for various tools, but the device complexity and number of battery types increases
Solution Approach 1:
The patent implements a universal battery platform that can serve multiple power levels and applications through a single battery type. The control unit dynamically manages power distribution to accommodate different tool requirements, making the battery system multi-functional rather than requiring separate batteries for each application.
Solution Approach 2:
The system uses dynamic power management where the control unit adjusts power delivery in real-time based on the connected tool's requirements. This dynamic adaptation allows a single battery type to provide varying power levels, replacing the need for multiple fixed-power battery designs.
2Reliability
If multiple dedicated chargers are used for different battery types, then each battery can be optimally charged, but the device complexity and number of chargers increases
Solution Approach 1:
The charging system is designed as a universal charger that can handle all battery types through intelligent detection and adaptive charging algorithms. The control unit identifies the connected battery type and adjusts charging parameters accordingly, providing optimal charging for each battery without requiring multiple dedicated charger models.
Solution Approach 2:
The charging system performs self-configuration by automatically detecting the battery type and selecting the appropriate charging profile. This self-service capability eliminates the need for users to manually select between different chargers, as the system adapts autonomously to the connected battery.
3Power
If motor generators are used for power supply, then sufficient power can be provided, but noise and exhaust emissions occur
Solution Approach 1:
The patent replaces mechanical motor generators with an electrical power supply system based on batteries and electronic power conversion. This substitution eliminates the combustion process that generates noise and exhaust emissions, while maintaining sufficient power output through electronic control and dynamic power management.
