Solution Overview
Problem
Existing light exposure measurement devices, such as watches, clip-ons, necklaces, and spectacles, face issues with data collection due to obstruction, forgetfulness, or inconvenience, particularly when worn with clothing or as additional accessories.
Innovation Solution
A wearable electronic ring equipped with light sensors and optional additional sensors, capable of processing and transmitting light data via Bluetooth, providing feedback and influencing user behavior based on environmental light conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If watches are used to measure light exposure, then light measurement capability is provided, but data collection is obstructed by clothing such as shirt sleeves
Solution Approach 1:
The patent transitions from wrist-mounted light measurement (2D surface) to finger-mounted light measurement (1D linear exposure). The finger ring device measures light exposure along the finger's length, capturing light intensity at multiple positions along the digit, thereby providing a new dimensional approach that avoids wrist obstruction by clothing while maintaining measurement accuracy.
2Measurement precision
If clip-ons and necklaces are used to measure light exposure, then light measurement capability is provided, but users easily forget to wear them or they are covered by clothing
Solution Approach 1:
The finger ring device serves multiple functions: it acts as both a fashion accessory and a light measurement device, eliminating the need for separate clip-ons or necklaces. The ring can be worn on any finger and provides continuous light exposure measurement without requiring additional accessories or reminding the user to wear separate devices.
Solution Approach 2:
The device is designed to be worn continuously on the finger without requiring user intervention or reminder. The ring automatically measures light exposure and transmits data without needing the user to actively manage or remember to wear it, as it is integrated into the finger itself.
3Measurement precision
If spectacles are used to measure light exposure, then light measurement capability is provided, but the device is intrusive when not worn and adding sensors to prescription spectacles is costly and inconvenient
Solution Approach 1:
The patent extracts the light measurement function from spectacles and relocates it to a standalone finger ring device. This separates the measurement function from the eyewear, eliminating the need to modify prescription spectacles with additional sensors while providing the same light exposure measurement capability in a simpler, more convenient form factor.
4Measurement precision
If a finger ring with multiple sensors is used, then comprehensive light data collection is achieved, but device complexity increases
Solution Approach 1:
The patent combines multiple light sensors with different spectral sensitivities into a single integrated ring structure. By merging the sensors and their data processing capabilities into one unified device worn on the finger, it achieves comprehensive light data collection across multiple wavelengths while maintaining a simple, wearable form factor that does not significantly increase perceived complexity.

Data Source
AI summary
A method includes sensing data indicative of a plurality of wavelengths of light utilizing one or more sensors forming a part of a sensor ring, storing the data on a memory device forming a part of the sensor ring, transmitting the data to a computing device external to the ring and receiving a photic environmental model from the computing device the photic environmental model based, at least in part, on the data.
