Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a battery pack with voltage different from the rated voltage is used, then compatibility and ease of operation are improved, but the electric tool may overheat or break down due to excessive voltage
Solution Approach 1:
The patent introduces an adaptor as an intermediary component between the battery pack and the electric tool. The adaptor includes a voltage conversion circuit that converts the voltage from the battery pack to match the rated voltage of the electric tool, thereby enabling compatibility with different battery packs while ensuring the electric tool operates safely within its voltage specifications
Solution Approach 2:
The patent changes the voltage parameter through the adaptor's voltage conversion circuit. The circuit detects the input voltage from the battery pack and converts it to the appropriate output voltage level required by the electric tool, dynamically adjusting the voltage parameter to maintain both compatibility and safety
2Power
If a battery pack with higher voltage than the rated voltage is used, then power output may be increased, but heat generation increases and breakdown occurs
Solution Approach 1:
The adaptor serves as a mediator that prevents excessive voltage from reaching the electric tool's motor. By converting the higher battery pack voltage to the rated voltage level, the adaptor ensures the motor receives appropriate power while avoiding overheating and breakdown
Solution Approach 2:
The voltage conversion circuit in the adaptor performs preliminary action by converting the voltage before it reaches the electric tool. This prevents the harmful effect of excessive voltage and heat generation before they can occur in the motor
