Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an ultraviolet lamp is used for sterilization and deodorization, then sterilization and deodorization functions are provided, but the device has a risk of damage due to impact and lower durability
Solution Approach 1:
The patent replaces the mechanical ultraviolet lamp system with a light emitting diode (LED) part that emits ultraviolet light. This substitution eliminates the fragile glass envelope and filament structure of traditional lamps, providing impact resistance while maintaining the sterilization function through UV light emission.
2Reliability
If an on generating device is used for sterilization and deodorization, then sterilization function is provided, but harmful ozone is generated
Solution Approach 1:
The patent introduces a filter part with photocatalytic functionality that converts the potentially harmful UV light into beneficial photocatalytic reactions. The photocatalytic filter decomposes organic compounds and odors while preventing harmful ozone generation, transforming the UV energy into a safer and more effective air purification process.
3Productivity
If traditional air purifying methods are used, then basic sterilization is achieved, but efficiency and durability are insufficient
Solution Approach 1:
The patent combines the light emitting diode part and the filter part into an integrated air purifying module. The LED provides UV light for sterilization while the photocatalytic filter simultaneously decomposes organic compounds and odors. This merged system achieves both high sterilization efficiency and durability through the complementary functions of its components.
