Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional pulse generator is used, then the device structure is simple, but it can only generate pulses with a specific width and cannot meet complex use requirements
Solution Approach 1:
The pulse generation circuit is divided into multiple pulse generation modules (first pulse generation module with n stages, second pulse generation module with m stages), where each module can independently generate pulses with different widths. This segmentation allows the system to produce multiple pulse width combinations without requiring a completely different circuit design for each pulse width, thus improving adaptability while managing complexity.
Solution Approach 2:
The patent creates a universal pulse generation system where the first and second pulse generation modules can generate pulses of different widths (first pulse with width T1, second pulse with width T2) that can be applied to the same load. This multi-functional capability allows a single circuit to serve multiple pulse width requirements, enhancing versatility without proportionally increasing complexity.
2Adaptability or versatility
If multiple pulse generation modules are added to generate different pulse widths, then pulse width adaptability is improved, but the device complexity increases
Solution Approach 1:
The first pulse generation module and second pulse generation module are merged into a single integrated circuit system with shared power supplies (first power supply and second power supply) and a common load connection. This merging approach allows multiple pulse generation capabilities to coexist while sharing common resources, thereby improving pulse combination capability without linearly increasing the number of independent components.
Solution Approach 2:
The patent implements a nested structure where the first and second pulse generation modules are organized in a hierarchical manner with multiple stages (n stages in first module, m stages in second module). Each module contains nested pulse generation units that can be selectively activated, allowing the system to generate different pulse widths by combining subsets of stages, thus achieving high adaptability with a structured, manageable complexity.
