Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If water droplets are used to form images on projection screens, then images can be displayed, but the water droplets do not retain their shape as they fall resulting in loss of image resolution
Solution Approach 1:
The patent applies ultrasonic vibration to the water supply system to generate monodisperse droplets with consistent size and shape. The vibration frequency is controlled to match the natural frequency of droplet formation, ensuring that droplets maintain their spherical shape as they fall and can be precisely controlled to form high-resolution images on projection screens.
Solution Approach 2:
The patent changes physical parameters including water pressure, ultrasonic vibration frequency, and nozzle temperature to optimize droplet formation. By precisely controlling these parameters, the system produces droplets with uniform size and shape that retain their composition stability during flight, enabling high-resolution image projection.
2Adaptability or versatility
If fixed nozzle patterns are used in water screen apparatus, then images can be projected, but changing configurations requires new apparatus for each layout reducing adaptability
Solution Approach 1:
The patent divides the nozzle system into modular segments that can be independently adjusted or reconfigured. Each module contains controllable nozzles that can be activated or deactivated electronically, allowing different projection patterns to be created by programming rather than physical reconfiguration, thus maintaining adaptability while reducing device complexity.
Solution Approach 2:
The patent implements dynamically controllable nozzles with adjustable flow rates and activation states through electronic control systems. This allows the apparatus to adapt to different configurations by changing operational parameters rather than physical structure, enabling flexible screen layouts without requiring new apparatus for each configuration.
3Length of moving object
If high installation heights are used for water screens, then larger images can be displayed, but droplet shape instability increases reducing image quality
Solution Approach 1:
The patent uses ultrasonic vibration at the nozzle to create highly stable, monodisperse droplets that maintain their shape over longer fall distances. The vibration ensures that droplets are formed with precise spherical geometry and uniform size, allowing them to retain their shape stability even at high installation heights, thereby enabling large-scale image projection with consistent quality.
Solution Approach 2:
The patent optimizes droplet formation parameters including vibration frequency, water pressure, and nozzle geometry to produce droplets with enhanced shape stability. By carefully selecting and controlling these parameters, the system extends the stable flight distance of droplets, enabling high installation heights while maintaining image quality.
