Ultrasonic Posture Detection Illumination Adjusting Light Color Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination apparatuses, such as desk lamps, often disturb users with noticeable alarms when detecting improper posture, relying on conscious responses rather than subtle adjustments to correct posture during reading or working.
Innovation Solution
An illumination apparatus with a detector using ultrasonic sensors to collect posture data, analyzing signals to determine the user's status, and adjusting light intensity and color temperature (CCT) to subtly encourage better posture without interrupting the user's activity, by increasing light intensity or CCT when leaning forward or backward, and decreasing CCT or adding a yellowish component to reduce concentration-related tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ultrasonic sensors are used to detect user posture and generate noticeable alarm signals, then posture detection capability is improved, but user comfort and concentration are deteriorated due to disturbing alarms during work
Solution Approach 1:
The patent applies color changes by adjusting the color temperature of the light source to convey posture information. When the user leans forward, the light becomes bluer (higher color temperature); when leaning backward, it becomes warmer (lower color temperature). This subtle visual feedback replaces the disturbing alarm signal while maintaining effective posture detection and guidance.
Solution Approach 2:
The patent changes the parameters of the light source, specifically the color temperature and intensity, to provide posture feedback. By dynamically adjusting these parameters based on detected posture, the system offers continuous guidance without interrupting the user's work, thus resolving the contradiction between effective detection and user comfort.
2Reliability
If alarm signals are used to remind users to raise their heads, then posture correction is improved, but the reliance on conscious response reduces effectiveness during concentrated work
Solution Approach 1:
The system enables self-service by providing automatic, continuous posture feedback through light adjustments without requiring user awareness or conscious response. The light automatically changes color temperature and intensity based on the user's posture, creating an intuitive feedback loop that operates independently of the user's attentional state.
Solution Approach 2:
The patent implements continuous feedback by constantly monitoring user posture and dynamically adjusting light parameters in real-time. This closed-loop feedback system provides ongoing guidance as the user works, eliminating the need for discrete alarm signals and conscious responses while maintaining reliable posture correction.
3Object-affected harmful factors
If light intensity and color temperature are adjusted to encourage better posture, then user comfort is improved, but device complexity increases due to multiple sensors and processing requirements
Solution Approach 1:
The patent applies multi-functionality by using the light source for both its primary illumination function and the secondary feedback function. The same light source that illuminates the workspace also provides posture information through color temperature and intensity changes, eliminating the need for separate feedback devices and reducing overall system complexity.
Solution Approach 2:
The patent merges the illumination function and feedback function into a single integrated system. The light source simultaneously performs both tasks, and the processor handles both illumination control and posture feedback generation, reducing the number of separate components needed while maintaining user comfort.
