Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the current value of the nerve stimulation pulse signal is arbitrarily changed during output, then the adaptability of the treatment is improved, but the safety and reliability deteriorate due to unexpected influences on the patient
Solution Approach 1:
The device allows dynamic switching between stimulation mode (where current value can be adjusted) and coagulation mode (where current value is fixed), enabling adaptability when needed while ensuring safety when output is active. The control unit dynamically changes the operational state based on mode and output status.
Solution Approach 2:
The control unit continuously monitors the output state and mode, and based on this feedback, automatically prohibits or allows changes to the target current value. When output is active, the system feedback-prohibits parameter changes to ensure safety; when output is inactive, changes are permitted for adaptability.
2Reliability
If the current value is fixed during output to ensure safety, then the reliability is improved, but the ease of operation deteriorates due to inability to adjust parameters
Solution Approach 1:
The system dynamically adjusts the operability of parameter changes based on the output state. During output, parameter changes are prohibited for safety; during non-output periods, parameter changes are enabled for ease of operation. This dynamic control resolves the contradiction between safety and operational flexibility.
Solution Approach 2:
The system allows preliminary setting and adjustment of target current values before output begins. Users can configure desired parameters in advance during the non-output state, ensuring ease of operation, and then initiate output with the pre-set safe parameters.
3Adaptability or versatility
If parameter changes are allowed during output for adaptability, then the versatility is improved, but the stability of treatment deteriorates due to unexpected influences
Solution Approach 1:
The control unit uses feedback from the output state to automatically enable or disable parameter changes. During active output, the system feedback-prohibits any changes to maintain stability. During non-output periods, feedback enables parameter adjustments for adaptability. This feedback-based control resolves the contradiction between stability and versatility.

AI summary
There is provided a high-frequency treatment device capable of stimulating a nerve of a patient or the like while avoiding an unexpected influence on the patient or the like. In a case where a setting operation of a target current value and an output start operation are performed through an operation unit 16 (input interface) in a stimulation mode, a main control unit 141 controls an output unit 110 to start output of a nerve stimulation pulse signal and to match a current value of the nerve stimulation pulse signal with the target current value. On the other hand, in a case where an output stop operation is performed through the operation unit 16, the main control unit 141 causes the output unit 110 to stop the output of the nerve stimulation pulse signal. During a period in which the nerve stimulation pulse signal is output by the output unit 110, a change in the target current value through the operation unit 16 is prohibited.
