Solution Overview
Problem
Existing methods for adjusting light exposure to align with an individual's circadian rhythm and color temperature preferences are limited by hardware and activity constraints, making it difficult to achieve a theoretically desirable light dose.
Innovation Solution
A method and control device that determine a light setting for a light source by aligning a target light profile with a light space, considering circadian stimulus and color temperature, and adjusting settings to be within the light source's capabilities and activity limitations, using a control device with circuitry to execute functions for determining and controlling the light source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the light source adjusts to achieve a theoretically desirable light dose for circadian rhythm regulation, then the circadian stimulus effect is improved, but hardware limitations prevent achieving the desired spectrum or intensity
Solution Approach 1:
The system changes the parameters of light (spectrum and intensity) dynamically to achieve desired circadian stimulus. By adjusting color temperature and brightness levels, the light source can provide appropriate circadian stimulation at different times of day without requiring hardware beyond its capabilities.
Solution Approach 2:
The system accepts that the light source cannot achieve the theoretically ideal light dose in all cases. Instead, it provides partial action by delivering the best possible circadian stimulus within hardware limitations, which is still beneficial for circadian rhythm regulation even if not perfectly optimal.
2Reliability
If the light source is adjusted to meet theoretical light dose requirements, then circadian rhythm alignment is improved, but activity limitations of the individual restrict the possible spectrum or intensity
Solution Approach 1:
The lighting system dynamically adjusts light parameters based on real-time conditions including individual activities. The system adapts its output to accommodate activity limitations while still providing circadian benefits, making the lighting control flexible and responsive to changing conditions.
Solution Approach 2:
The system changes light parameters (intensity, spectrum) according to the individual's current activity state. When activity limitations are detected, the system modifies the light dose parameters to remain appropriate for the current activity while still contributing to circadian rhythm regulation.
3Productivity
If the system provides personalized light adjustment for circadian stimulation, then well-being and performance are improved, but hardware and activity constraints limit the achievable light settings
Solution Approach 1:
The system optimizes light parameters within available constraints to maximize performance and well-being benefits. By carefully selecting appropriate intensity and spectrum parameters that work within hardware and activity limitations, the system still achieves meaningful circadian stimulation and performance enhancement.
Solution Approach 2:
The system accepts partial achievement of ideal light dosing and provides beneficial circadian stimulation within limitations. Even though the full theoretical light dose cannot always be delivered, the partial action provided still yields positive effects on well-being and performance.
