Engineering Contradiction Analysis
1Power
If a high voltage process is adopted to fabricate driving chips to produce higher driving voltages, then the driving voltage requirement is met, but the device size increases, manufacturing costs increase, and production capacity decreases
Solution Approach 1:
The patent segments the voltage generation function by separating the high voltage output requirement from the low voltage fabrication process. The driving circuit generates high driving voltages through circuit configuration and voltage multiplication techniques, while the fabrication process itself operates at low voltage. This segmentation allows the circuit to achieve high power output without requiring high voltage fabrication, thereby improving production capacity.
Solution Approach 2:
The patent changes the voltage parameter relationship by using voltage multiplication circuits and configuration techniques that generate high driving voltages from low input voltages. The circuit employs capacitive coupling, inductive coupling, and feedback mechanisms to amplify the input voltage to the required driving level, enabling high power output with low voltage fabrication processes.
2Power
If a high voltage process is adopted to fabricate driving chips to produce higher driving voltages, then the driving voltage requirement is met, but the manufacturing costs increase
Solution Approach 1:
The patent separates the high voltage generation function from the fabrication process, allowing standard low-voltage manufacturing techniques to be used. The high driving voltages are generated through circuit design and voltage multiplication rather than requiring high voltage fabrication, thereby reducing manufacturing costs and improving ease of manufacture.
Solution Approach 2:
The patent employs voltage multiplication circuits and configuration techniques that generate high driving voltages from low input voltages through capacitive coupling, inductive coupling, and feedback mechanisms. This parameter transformation enables the use of cost-effective low-voltage fabrication processes while still achieving the required high driving voltages.
3Power
If a high voltage process is adopted to fabricate driving chips to produce higher driving voltages, then the driving voltage requirement is met, but the device size increases
Solution Approach 1:
The patent uses voltage multiplication circuits and configuration techniques that generate high driving voltages from low input voltages through capacitive and inductive coupling. This approach allows the device to achieve high power output with smaller component sizes, as the voltage multiplication is achieved through circuit topology rather than requiring large high-voltage rated components.
