Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple electric conductors are processed simultaneously to increase production efficiency, then productivity is improved, but current distribution becomes uneven causing capacitance variation
Solution Approach 1:
The patent divides the current supply system into separate constant current sources for each electric conductor. Instead of using a single current source for multiple conductors, each conductor receives current from its own dedicated constant current source, ensuring equal current distribution and eliminating capacitance variation while maintaining simultaneous processing capability
Solution Approach 2:
The patent changes the electrical parameter control method by introducing constant current sources that actively regulate and maintain equal current values across all electric conductors. This parameter control ensures that despite simultaneous processing of multiple conductors, the current flowing through each conductor remains uniform, thereby achieving consistent capacitance values
2Device complexity
If conventional current sources are used without constant current control, then device complexity is reduced, but semiconductor layer formation becomes uneven
Solution Approach 1:
The patent employs constant current sources that incorporate feedback mechanisms to monitor and adjust the current flowing through each electric conductor. This feedback control ensures that the current remains constant and equal across all conductors, producing uniform semiconductor layers while maintaining reasonable device complexity through the use of standard constant current source circuits
