Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the minimum driving voltage is set high (12V) to ensure reliable motor startup, then the motor can start reliably, but the device cannot operate at lower voltages (6V) during normal use without cumbersome re-initialization operations
Solution Approach 1:
The system performs preliminary action by automatically applying the minimum driving voltage (12V) only during the startup phase to ensure reliable motor initialization, then automatically transitions to the lower operating voltage (6V) for normal use. This eliminates the need for users to manually re-initialize the device when switching between startup and operation phases.
Solution Approach 2:
The voltage supply mode is made dynamic by automatically switching between two voltage states: minimum driving voltage (12V) during startup and operating voltage (6V) during normal operation. The controller dynamically adjusts the voltage based on the operational phase, allowing the device to adapt its electrical characteristics to different operational requirements without user intervention.
2Use of energy by moving object
If the device operates at lower voltage (6V) for normal use, then energy consumption is reduced, but the device cannot start without first being initialized at higher voltage (12V)
Solution Approach 1:
The device performs self-service by automatically managing its own voltage requirements. The controller detects when the device is in startup mode versus normal operation mode and automatically adjusts the voltage supply accordingly, eliminating the need for user intervention to switch between voltage modes and simplifying the operational workflow.
Solution Approach 2:
The system performs the necessary high-voltage initialization automatically as a preliminary action before normal low-voltage operation. This preliminary high-voltage application ensures the motor is properly initialized, then the system transitions to energy-efficient low-voltage operation without requiring user awareness or action.
3Adaptability or versatility
If the device frequently switches between startup and operation states, then flexibility is improved, but the cumulative re-initialization operations become very time-consuming
Solution Approach 1:
The voltage supply system operates dynamically, automatically adapting between startup and operation modes without requiring time-consuming manual re-initialization. The controller continuously monitors the operational state and adjusts voltage accordingly, enabling frequent start-stop operations without cumulative time loss.
Solution Approach 2:
The device serves itself by automatically managing voltage transitions during frequent start-stop operations. The controller handles the entire voltage adjustment process autonomously, eliminating the repetitive manual re-initialization operations that would otherwise consume significant time during frequent operational changes.

AI summary
The present invention provides a controlling apparatus for a skin resurfacing device performing a surgical procedure on a human skin with a surgical needle, including: a controller 20; a voltage regulator 50 configured to regulate a voltage supplied to the skin resurfacing device from a power supply 10 according to a control of the controller; and a starting switch 80 configured to turn on/off a supply of power between the voltage regulator and the skin resurfacing device, in which the controller controls the voltage regulator so as to output a preset jump start voltage to the skin resurfacing device every time the starting switch is turned on, if a jump start function that is a function of starting the skin resurfacing device is set by a starting voltage when an operating voltage of the skin resurfacing device is lower than the starting voltage of the skin resurfacing device at the time of the surgical procedure.
