Dynamic Light Source for Natural Sunrise Wake-Up Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional alarm clocks abruptly wake users, leading to discomfort and reduced energy levels upon waking, whereas simulating a natural sunrise through gradually increasing light intensity and color temperature is shown to improve wake-up experiences.
Innovation Solution
An apparatus with a sliding or extendable light source that mimics a natural sunrise by adjusting light intensity and color temperature over a wake-up period, potentially accompanied by infrared radiation, sound integration, and projection features to enhance the wake-up simulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional alarm clocks use abrupt alarm sounds to wake users, then the wake-up function is achieved quickly, but the user experiences discomfort and reduced energy levels
Solution Approach 1:
The patent changes the parameters of light intensity and color temperature over time to simulate natural sunrise. The light intensity gradually increases from low to high levels, and the color temperature transitions from warm to cool tones, creating a gentle wake-up effect that avoids user discomfort while maintaining wake-up efficiency
Solution Approach 2:
The light source is made dynamic by continuously adjusting its intensity and color temperature during the wake-up period. This dynamic adjustment mimics the natural progression of sunrise, providing a progressive stimulation that is more comfortable than static abrupt alarms
2Object-affected harmful factors
If light intensity is gradually increased to simulate natural sunrise, then user comfort and energy levels improve, but the wake-up period extends over time
Solution Approach 1:
By systematically changing light intensity and color temperature parameters over a controlled time period, the patent achieves both comfort and efficiency. The gradual parameter changes create a natural-like transition that users find comfortable while the overall process remains time-efficient
Solution Approach 2:
The wake-up process is structured as a periodic sequence with specific phases: initial low-intensity warm light, gradual intensity increase, color temperature shift, and final high-intensity state. This periodic structure provides comfort through gradual changes while maintaining a defined, efficient total duration
3Device complexity
If a single light source is used for wake-up function, then the device structure is simple, but the ability to simulate natural sunrise accurately is limited
Solution Approach 1:
The lighting system is segmented into multiple independent light sources with different color temperatures. This segmentation allows each light source to contribute to different aspects of the sunrise simulation (warm tones early in the period, cooler tones later), achieving accurate natural sunrise simulation while keeping individual components simple
Solution Approach 2:
Multiple light sources with different characteristics are merged into a single integrated lighting system. The combination of different color temperature light sources creates a more complete and accurate sunrise simulation than any single light source could achieve alone, while the merged system remains manageable in complexity
