Solution Overview
Problem
Existing control devices for energy treatment tools struggle to maintain the resistance value of a heating element within a target range over time, especially during cutting operations, which affects the consistency and efficiency of the treatment process.
Innovation Solution
A control device with a processor that sets a target temperature for the heating element and switches between two phases of temperature followability, adjusting the electrical energy output based on predetermined conditions related to the temperature and electrical characteristic values such as power, current, and voltage to ensure the heating element maintains the target temperature and reduces energy output when fluctuations exceed a certain range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the control device maintains high followability of temperature to target temperature, then the temperature consistency is improved, but the response time to detect and correct deviations increases
Solution Approach 1:
The control device dynamically switches between two control phases: a first phase with high followability for temperature consistency and a second phase with lower followability for faster response. The processor determines when to switch phases based on whether the treatment target has been cut to a desired extent, allowing the system to adapt its control characteristics in real-time to optimize both temperature consistency and response time.
2Device complexity
If the control device uses a single control phase throughout the treatment process, then the control logic is simplified, but the treatment performance and precision deteriorate
Solution Approach 1:
The control process is segmented into two distinct phases: a first control phase with high followability settings and a second control phase with lower followability settings. The processor switches between these phases based on treatment progress, allowing each phase to be optimized for its specific function while maintaining overall system manageability through clear phase transition criteria.
3Measurement precision
If the control device maintains temperature followability throughout the entire treatment process, then the temperature control precision is improved, but the risk of tissue degeneration increases
Solution Approach 1:
The control device dynamically adjusts the level of temperature followability based on treatment progress. During the first phase when the treatment target needs to be cut, high followability maintains precise temperature control. After the cut is achieved, the device transitions to the second phase with reduced followability, allowing temperature to deviate more freely and thereby reducing the risk of tissue degeneration from excessive heat maintenance.
