Progressive Red Light Sleep Aid Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sleep-inducing devices that emit red light are not designed to effectively aid in the initial falling asleep process and can be disruptive due to untimely light cycles triggered by user movements, lacking efficiency in energy use and adaptability to individual sleep characteristics.
Innovation Solution
A device with a light source emitting monochromatic red light that automatically decreases in power over time from a maximum to a minimum value, controlled by a predefined law, allowing for continuous and progressive dimming to create a relaxing atmosphere without disturbing melatonin production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motion sensors are used to detect user displacement and trigger lighting, then safe nighttime displacement is secured, but the device cannot be placed in bedrooms as it disturbs initial falling asleep through untimely light-up cycles
Solution Approach 1:
The patent extracts the motion sensing function from the lighting control function. The lighting device no longer responds to motion triggers, eliminating the disruptive light-up cycles in bedrooms while preserving safe nighttime displacement through other means (such as ambient motion-aware lighting systems elsewhere in the home).
Solution Approach 2:
Instead of using motion detection to trigger light (which disturbs sleep), the system inverts the approach by using motion detection to suppress or avoid triggering light in bedroom environments, or by placing the device in locations where motion-triggered lighting is beneficial (hallways, stairs) rather than in bedrooms.
2Object-affected harmful factors
If red light is used to minimize disruption to circadian rhythm, then melatonin production is preserved, but the device is not effective in aiding initial falling asleep
Solution Approach 1:
The patent applies periodic action by implementing gradual dimming cycles where the red light intensity decreases over time in structured intervals. This periodic reduction in intensity mimics natural sunset patterns, providing rhythmic visual cues that signal the brain to transition to sleep mode while maintaining the circadian-rhythm-friendly red wavelength throughout.
Solution Approach 2:
The system changes the intensity parameter of the red light over time, transitioning from higher initial intensity to progressively lower intensity. This parameter change (intensity modulation) enhances the soothing effect and facilitates falling asleep, while the wavelength parameter remains constant in the red range to preserve melatonin production.
3Use of energy by moving object
If lighting devices are equipped with motion and light sensors to optimize energy consumption, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The lighting device serves itself by using ambient light sensors to detect darkness levels and automatically determine when activation is appropriate, eliminating the need for complex motion-triggered control systems. The device self-regulates its operation based on environmental light conditions, simplifying the overall control architecture while maintaining energy efficiency.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device efficiently aids in falling asleep by providing a soothing, progressively dimming red light environment that adapts to individual sleep habits, conserves energy, and maintains melatonin regulation, making it suitable for various settings without disrupting circadian rhythms.

Data Source
AI summary
The invention concerns a device for helping a user fall asleep, comprising a light source designed to emit a substantially monochromatic red or quasi-monochromatic light encouraging the user to fall asleep, characterized in that it comprises a control unit designed to automatically control said light source according to a predefined law according to which the light power emitted by said light source decreases gradually over time in such a way as to change automatically between a maximum power value and a minimum power value, the light power emitted by said light source at a given time always being greater than or equal to the light power emitted at a subsequent time.
