Solution Overview
Problem
Existing high-frequency treatment systems lack precise control over the output of high-frequency electric power, leading to inefficiencies in treating targets like living body tissues, as they rely on threshold-based integration values for stopping the power supply without adjusting for varying impedance and treatment progress.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a threshold-based integration value is used to stop power supply, then the control method is simple, but the treatment precision and adaptability to varying impedance are insufficient
Solution Approach 1:
The system continuously monitors the integration value of high-frequency electric power output and compares it against a dynamically adjusted target locus. The controller receives feedback from the detector and adjusts the power generator output in real-time to maintain the integration value within the target range, enabling precise control that adapts to varying tissue impedance during treatment
Solution Approach 2:
The target locus is not a fixed threshold but a dynamic reference that evolves during treatment. The system adjusts the target integration value based on treatment progress and impedance changes, allowing the control parameter to adapt dynamically rather than relying on a static threshold value
2Manufacturing precision
If real-time monitoring and adjustment of high-frequency electric power is implemented, then treatment precision is improved, but device complexity increases
Solution Approach 1:
The detector, integration value calculator, target locus setting section, and controller are merged into an integrated control system. The detector monitors power output, the calculator computes integration values, the target locus setting section establishes reference values, and the controller coordinates all components to work together, reducing overall system complexity through functional integration
Solution Approach 2:
The system performs self-regulation by automatically monitoring its own power output, calculating integration values, comparing them against target loci, and adjusting the generator output without external intervention. The controller autonomously maintains the integration value within the target range, eliminating the need for manual monitoring and adjustment
3Productivity
If the integration value is continuously monitored and compared with target locus, then power delivery control is optimized, but measurement and detection requirements increase
Solution Approach 1:
The integration value calculator serves as an intermediary that processes the raw power detection data and transforms it into a meaningful integration value that can be directly compared against the target locus. This intermediary computation layer simplifies the measurement requirement by converting complex power characteristics into a single comparable parameter

Implementation Method 1
a high-frequency energy generator (high-frequency electric power generator) which generates high-frequency electric power that is supplied to the treatment section... causing a high-frequency current to flow to the treated target, such as a living body tissue
Implementation Method 2

AI summary
A high-frequency control unit includes an integration value calculator calculating a measured integration value, which is a measured value of an integration value of an output high-frequency electric power from an output start time, with a passage of time. The high-frequency control unit includes a target locus setting section setting target locus which indicates, with a passage of time, a target integration value that is a target value of the integration value of the output high-frequency electric power from the output start time, and a controller comparing, with a passage of time, the measured integration value with the target locus, and controlling, with a passage of time, an output state of the high-frequency electric power based on a comparison result.
