1Illumination intensity

If conventional light irradiation devices are used, then illumination function is provided, but ultraviolet wavelength exposure is insufficient for synthesizing functional substances

Engineering Contradiction:

Improveultraviolet wavelength exposureVSAvoidspectrum coverage

Core Design Contradiction:

Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The patent combines multiple light sources with different wavelength characteristics (visible light source and ultraviolet light source) into a single illumination device. This merging allows the device to provide both adequate visible illumination and sufficient ultraviolet exposure for functional substance synthesis, resolving the contradiction between illumination intensity and spectrum coverage.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The illumination device is designed to perform multiple functions simultaneously: providing general illumination for visibility and delivering specific ultraviolet wavelengths for catalyzing functional substance synthesis in the human body. This multi-functionality approach enables a single device to address both illumination needs and health-related synthesis requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If special light sources providing specific functions are used, then treatment function is improved, but the device can be used only as treatment device

Engineering Contradiction:

Improvetreatment functionVSAvoidusage scope

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent designs the illumination device to serve dual purposes: it functions as a general illumination device for everyday use and as a treatment device for catalyzing functional substance synthesis. By integrating both capabilities, the device maintains reliability for treatment while expanding versatility to include general illumination, allowing users to benefit from both functions with a single device.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If ultraviolet light is provided to catalyze synthesis of functional substance, then synthesis effect is improved, but harmful effects to human body may occur

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent employs light sources that emit specific ultraviolet wavelength bands (particularly UVB) that are most effective for catalyzing functional substance synthesis while minimizing harmful effects. By selecting particular wavelength ranges rather than broad-spectrum ultraviolet, the device achieves high synthesis productivity while reducing harmful radiation exposure to safe levels.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The device controls the intensity and wavelength parameters of the ultraviolet light sources to optimize the balance between synthesis effectiveness and safety. By adjusting these parameters, the device delivers sufficient ultraviolet exposure to catalyze functional substance synthesis while maintaining radiation levels that do not cause harmful effects to human tissue.
