Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional air purifiers are used to purify air in enclosed environments, then pathogenic microorganisms can be adsorbed, but they cannot effectively kill the microorganisms
Solution Approach 1:
The patent changes the wavelength parameter of the light source to deep ultraviolet range (200-400nm), which has sufficient energy to kill pathogenic microorganisms by damaging their DNA/RNA, transforming the function from mere adsorption to effective sterilization
2Reliability
If high-power air purification equipment is installed in large places, then disinfection capability is improved, but construction cost and power consumption greatly increase
Solution Approach 1:
The patent divides the air purification function into modular units that can be distributed throughout the space, with each unit containing a laser apparatus and reflection adjusting assembly, allowing localized disinfection without requiring high-power centralized equipment
Solution Approach 2:
The patent replaces traditional mechanical filtration and high-power UV lamp systems with a laser-based system that uses optical reflection and interference to create standing waves for microbial killing, significantly reducing power consumption
3Reliability
If conventional laser technology is used for air disinfection, then pathogenic microorganisms can be killed, but laser leakage occurs causing harm to human bodies
Solution Approach 1:
The patent introduces reflection adjusting assemblies as intermediaries that confine the laser within a controlled optical path using reflection and interference, preventing laser leakage while maintaining disinfection effectiveness
Solution Approach 2:
The patent creates standing waves through interference of laser beams reflected at specific angles, forming periodic high-energy regions that kill microorganisms while the laser remains confined and does not leak
4Reliability
If conventional laser equipment is used for air disinfection, then disinfection function is provided, but the equipment is high in cost, complex in device structure, and unable to be replaced
Solution Approach 1:
The patent divides the laser system into modular units with standardized laser apparatus and reflection adjusting assemblies, making the equipment easier to manufacture, install, replace, and maintain while maintaining full disinfection functionality
Solution Approach 2:
The patent uses adjustable reflection assemblies that can dynamically control the laser path and standing wave formation, providing adaptability for different installation environments while keeping the basic device structure simple and replaceable
