Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional pulse generation circuitry with separate first and second pulse generation units is used, then bipolar pulsed voltage can be generated, but the apparatus size becomes large and complex
Solution Approach 1:
The patent combines the first and second pulse generation units into a single integrated pulse generation unit. The inductors, capacitors, and switching elements are arranged in a unified structure where first inductors and second inductors share common connections, capacitors are connected between corresponding inductors, and switching elements control current paths to generate both positive and negative pulsed voltages from a single DC power supply, thereby reducing apparatus size while maintaining bipolar voltage generation capability
Solution Approach 2:
The integrated pulse generation unit serves multiple functions: it generates both positive pulsed voltage (first pulsed voltage) and negative pulsed voltage (second pulsed voltage) with opposite polarities, replaces what would traditionally require separate pulse generation units and multiple DC power supplies, and enables compact bipolar pulsed voltage generation through a unified circuit architecture
2Adaptability or versatility
If conventional pulse generation circuitry with multiple DC power supplies is used, then bipolar pulsed voltage can be generated, but manufacturing costs increase
Solution Approach 1:
A single DC power supply is designed to perform multiple functions by charging different sets of capacitors through different switching configurations. The same power supply charges first capacitors for generating positive pulsed voltage and second capacitors for generating negative pulsed voltage, eliminating the need for separate power supplies and reducing manufacturing costs
