Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single waveform type of electric field signal is used to act on tumor cells, then the device complexity is reduced, but the adaptability to different types of tumor cells deteriorates
Solution Approach 1:
The patent implements dynamic waveform selection by providing a signal generation module that can switch between multiple waveform types (sine wave, square wave, triangle wave, sawtooth wave) based on different tumor cell types and treatment requirements. This dynamic adaptability allows the device to optimize treatment efficacy for various tumor cells while maintaining a unified device structure.
Solution Approach 2:
The patent creates a universal electric field generation device that can perform multiple waveform types through integrated signal generation, modulation, and filtering modules. The device universally handles different tumor cell types by selecting appropriate waveforms, eliminating the need for multiple specialized devices while maintaining comprehensive treatment capability.
2Adaptability or versatility
If multiple waveform types are generated to improve adaptability to different tumor cells, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent merges signal generation, waveform modulation, and filtering functions into a single integrated device. The signal generation module produces multiple waveform types, the modulation module converts them to pulse sequences, and the filtering module refines the output - all within one unified system that reduces overall device complexity while maintaining multi-waveform capability.
Solution Approach 2:
The patent implements a universal device architecture where a single electric field generation device performs multiple waveform synthesis functions. The integrated design allows one device to replace multiple specialized devices, achieving adaptability to different tumor cells without proportionally increasing device complexity.
3Adaptability or versatility
If the frequency of the electric field signal is adjusted to match different tumor cell characteristics, then the adaptability is improved, but the control complexity increases
Solution Approach 1:
The patent implements dynamic frequency adjustment capability in the signal generation module, allowing the electric field signal frequency to be varied according to different tumor cell characteristics. The controller automatically manages frequency parameters, providing adaptive treatment without requiring complex manual control procedures.
