Solution Approach 1:

The patent implements dynamic spectral power distribution adjustment by enabling the light delivery system to change wavelengths and intensities in real-time based on user needs and environmental conditions. The system transitions from static fixed-wavelength delivery to dynamic adaptive delivery, allowing spectral characteristics to be modified during operation to match circadian rhythms, user preferences, and ambient light conditions.

Inventive Principle:

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The system performs self-characterization by automatically collecting and processing user data including circadian rhythm patterns, skin tone, eye color, and environmental conditions. The apparatus autonomously determines optimal light delivery parameters without requiring manual user input, thereby maintaining high measurement precision while significantly improving ease of operation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements continuous feedback loops where sensors monitor user response to light exposure and environmental conditions, and the controller automatically adjusts spectral power distribution based on this feedback. This closed-loop control ensures accurate capture of user needs while eliminating cumbersome manual interaction.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If comprehensive user data collection is implemented, then adaptability to individual needs is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs multi-functional components that serve multiple purposes. For example, the optical sensors not only measure ambient light conditions but also assess user skin tone and eye color. The controller integrates diverse functions including data collection, processing, light delivery control, and safety monitoring within a single unified system, reducing overall complexity despite comprehensive adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Reliability

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system implements periodic or pulsed light delivery patterns rather than continuous illumination. By delivering light in optimized pulses or cycles that match circadian rhythms and therapeutic requirements, the system maintains high therapeutic efficacy while significantly reducing overall energy consumption compared to continuous operation.

Inventive Principle:

AI summary

System and methods to generate and control light for use in therapeutic, aesthetic, disinfection, and other light-related applications in settings where a significant portion of skin is exposed to light (e.g., shower, sauna, locker-room). Characteristics of the light are controlled to simulate specific spectra of natural sunlight and unnatural light and deliver targeted doses of UV light (e.g., for vitamin-D synthesis, boosting the immune system, tanning), UV-C light (e.g., to kill bacteria, viruses, and fungi), visible light (e.g., to anchor a circadian rhythm to improve mood, metabolism, cognitive functions, physical performance, and sleep), and red or infrared light (e.g., for skin rejuvenation, wound healing, tissue repair, blood-flow, muscle recovery, circulation) while, at the same time, minimizing negative impacts of light exposure. Various embodiments may further create the experience of an outdoor shower.
