Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fluorescent tubes or high-pressure lamps are used for irradiation, then the device can provide ultraviolet radiation for tanning, but the housing parts become relatively large and the device occupies considerable space
Solution Approach 1:
The patent replaces traditional fluorescent tubes and high-pressure lamps with LED modules that emit ultraviolet radiation. This substitution of the radiation source enables compact housing while maintaining effective irradiation output, directly resolving the contradiction between radiation intensity and housing size.
Solution Approach 2:
The patent changes the operating parameters and physical characteristics of the radiation source by using LEDs with specific wavelength emissions (UVA and UVB spectra). This parameter change allows for smaller form factor while maintaining the required irradiation effectiveness, solving the space constraint problem.
2Illumination intensity
If fluorescent tubes or high-pressure lamps are used, then irradiation can be provided, but customized adjustment for different users and irradiation results is hardly enabled
Solution Approach 1:
The patent segments the irradiation system into multiple independently controllable LED modules, each capable of emitting different spectra (UVA, UVB). This segmentation enables customized irradiation programs for different user types and body areas, directly addressing the lack of adaptability in traditional systems.
Solution Approach 2:
The patent implements dynamic control of LED modules through a controller that can adjust the activation and intensity of specific modules based on user characteristics and desired irradiation results. This dynamic adaptability allows the system to customize irradiation parameters for different users, overcoming the static nature of traditional fluorescent tube systems.
3Illumination intensity
If fluorescent tubes or high-pressure lamps are used for irradiation, then ultraviolet radiation can be generated, but energy consumption is very high
Solution Approach 1:
The patent substitutes high-energy consuming fluorescent tubes and high-pressure lamps with LED technology that generates ultraviolet radiation. This substitution fundamentally changes the energy conversion efficiency, reducing overall energy consumption while maintaining effective irradiation output.
Solution Approach 2:
The patent changes the energy efficiency parameters of the radiation source by using LEDs with higher efficiency conversion from electrical to optical energy. This parameter change in the source technology directly reduces energy consumption while maintaining the required ultraviolet radiation generation capability.
