Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern people, especially those living indoors, face reduced exposure to natural light, leading to potential deficiencies in vitamin D and serotonin synthesis, which can contribute to health issues like osteoporosis and depression, and there is a need for a light-emitting device that mimics natural light without the harmful effects of direct sunlight exposure.
Innovation Solution
A light-emitting device comprising a combination of visible light and ultraviolet B (UVB) emitters, controlled by a processor to achieve a threshold illuminance value, simulating natural light and inducing vitamin D and serotonin production safely indoors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If natural light exposure is increased to induce vitamin D and serotonin synthesis, then health benefits are improved, but skin damage and harmful effects from strong sunlight occur
Solution Approach 1:
The patent divides natural light into separate spectral components by using distinct light emitters for visible light (400-700nm) and ultraviolet B light (280-320nm). This segmentation allows each component to be delivered independently and controllably, enabling vitamin D and serotonin synthesis while avoiding the harmful effects of strong sunlight through precise spectral control
Solution Approach 2:
The patent controls and adjusts parameters such as illuminance values, color temperatures, and spectral distribution of the light emitters. By dynamically changing these parameters, the system can provide appropriate UVB exposure for vitamin D synthesis while maintaining safe visible light levels, thus preventing skin damage while achieving health benefits
2Reliability
If indoor light emission intensity is increased to simulate natural light, then vitamin D and serotonin synthesis is promoted, but energy consumption and potential eye strain increase
Solution Approach 1:
The system dynamically adjusts illuminance values and spectral distribution parameters based on time of day, weather conditions, and user needs. This allows optimization of energy consumption by providing higher UVB content in the morning when vitamin D synthesis is most beneficial, while reducing intensity in the evening to prevent eye strain and save energy
Solution Approach 2:
The patent incorporates sensors and control mechanisms that monitor environmental conditions and user responses, adjusting light emission parameters accordingly. This feedback loop enables the system to achieve effective neurotransmitter synthesis while minimizing energy consumption by avoiding unnecessary high-intensity emission during times when natural light would not be present anyway
