Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed power output is provided through the transmission of the power tool, then safety limitations are achieved by restricting tool operation through mechanical switches, but adaptive adjustment of transmission control based on different performance of work heads cannot be achieved
Solution Approach 1:
The patent replaces the mechanical switch system with an electronic control system. The MCU control unit receives identification signals from different tool heads and electronically adjusts transmission control parameters, eliminating the need for mechanical switches while achieving both safety limitations and adaptive adjustment capabilities.
Solution Approach 2:
The patent implements a feedback mechanism where the identification signal from the tool head is read by the MCU control unit, which then adjusts the transmission control parameters accordingly. This closed-loop feedback system enables adaptive adjustment of power output based on the specific tool head being used.
2Device complexity
If fixed power output is provided through the transmission of the power tool, then the structure remains simple, but the power requirements for each type of work head are ignored and optimal performance cannot be achieved
Solution Approach 1:
The patent replaces simple mechanical power transmission with an electronically controlled transmission system. The MCU control unit monitors tool head identification and dynamically adjusts transmission parameters, achieving optimal performance for each tool head type while maintaining relatively simple overall system architecture.
Solution Approach 2:
The patent introduces dynamic adjustment capability to the previously static power transmission system. The transmission control parameters are dynamically modified based on the identified tool head type, allowing the system to optimize performance for different applications while maintaining a unified hardware platform.
