Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single pulse generation module is used, then the device structure is simple, but the pulse width is limited to a specific value and cannot meet diverse requirements
Solution Approach 1:
The pulse generation apparatus is divided into multiple independent pulse generation modules (first pulse generation module and second pulse generation module), each capable of generating pulses with different width characteristics. This segmentation allows the system to provide diverse pulse widths without requiring a completely different device structure, thus improving adaptability while maintaining reasonable complexity.
Solution Approach 2:
The apparatus is designed with multi-functional capability by integrating multiple pulse generation modules that can operate independently or in combination. The first and second pulse generation modules can each function separately to provide different pulse widths, or work together to generate composite pulses, making the device universally applicable to various pulse width requirements without needing separate dedicated devices.
2Adaptability or versatility
If multiple pulse generation modules are used to achieve different pulse widths, then the adaptability is improved, but the device structure becomes more complex
Solution Approach 1:
The first and second pulse generation modules are merged into a single integrated apparatus with shared control and power supply systems. The modules can be combined to generate composite pulses with synergistic effects, achieving enhanced functionality while avoiding the complexity of completely separate devices. The merging allows coordinated operation that improves adaptability without linearly increasing overall system complexity.
3Reliability
If composite pulses with different widths are generated, then the ablation effect on tumor cells is improved, but the control system becomes more complex
Solution Approach 1:
The control system incorporates feedback mechanisms that allow the host computer to coordinate the operation of multiple pulse generation modules based on desired output characteristics. By using feedback control, the system can generate composite pulses with precise timing and amplitude relationships needed for effective tumor cell ablation, while maintaining manageable control complexity through automated adjustment rather than manual configuration.

AI summary
Embodiments of the present application provide a cooperative pulse generation apparatus, device and generation method. The synergistic pulse generation apparatus comprises a drive circuit and a pulse generation circuit. The drive circuit receives a first control signal and a second control signal sent by a host computer, converts the first control signal into a first drive signal, and converts the second control signal into a second drive signal. The pulse generation circuit comprises a first power supply, a second power supply, a first pulse generation module, and a second pulse generation module. The first pulse generation module stores electric energy supplied by the first power supply and discharges the electricity under the control of the first drive signal to form a first pulse signal, and the second pulse generation module stores electric energy provided by the second power supply and discharges the electricity under the control of the second drive signal to form a second pulse signal. The present embodiment can selectively form a first pulse signal and/or a second pulse signal having different widths, thereby achieving the purpose of applying a composite pulse to a load.
