Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If software animation is used to show transmission line waves, then the visualization capability is improved, but the flexibility and types of transmission line simulation are limited
Solution Approach 1:
The transmission line is divided into multiple discrete modular segments that can be independently selected and configured. Each module represents a specific transmission line configuration with defined electrical characteristics, allowing flexible assembly of different transmission line types and lengths while maintaining clear visualization through the modular structure.
Solution Approach 2:
The system allows dynamic reconfiguration of transmission line parameters by swapping modular components. Users can change characteristic impedance, line length, and other parameters by replacing modules, enabling real-time exploration of different transmission line behaviors while maintaining visual representation.
2Adaptability or versatility
If algorithms are used to generate dynamic wave animation, then the software freedom is improved, but the device complexity increases
Solution Approach 1:
Instead of using complex algorithms to simulate wave behavior, the patent uses physical modular representations that directly model transmission line characteristics. The modular components are designed to naturally exhibit the electrical behaviors they represent, eliminating the need for complex computational algorithms while maintaining visualization capability.
Solution Approach 2:
The patent replaces software-based algorithmic simulation with a physical modular system that inherently demonstrates transmission line behavior. The electrical characteristics of the modular components directly produce the wave phenomena being studied, substituting mechanical/electrical reality for computational simulation.
3Measurement precision
If abstract formulas are used to describe transmission line theory, then the theoretical accuracy is improved, but the ease of understanding for beginners deteriorates
Solution Approach 1:
The patent uses visual indicators such as colored LEDs or illuminated elements on the modular components to represent wave amplitude, phase, and other electrical parameters. This visual coding system translates abstract electrical concepts into intuitive visual information that beginners can easily understand while maintaining theoretical accuracy.
Solution Approach 2:
The modular transmission line components serve as intermediaries between abstract mathematical formulas and physical wave phenomena. They provide a tangible, visual representation that bridges the gap between theoretical equations and practical understanding, making complex concepts accessible to beginners.
