Solution Overview
Problem
Optical skin measuring sensors face challenges in miniaturization due to structural issues related to securing an optical path and blocking external light, making it difficult to integrate them into electronic devices like portable terminals without affecting aesthetics or functionality.
Innovation Solution
An electronic device is designed to utilize pre-installed sensors, such as HRM or PPG sensors, to measure biometric information using visible and infrared light, allowing for the provision of skin-related information like melanin index, erythema index, and skin tone without the need for additional hardware or design changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate optical skin measuring sensor is installed in an electronic device, then skin measurement functionality is improved, but device structure complexity and aesthetic appearance deteriorate due to additional holes or sensor replacement
Solution Approach 1:
The patent applies multi-functionality by enabling existing sensors (proximity sensor, HRM sensor, PPG sensor) to perform both their original functions and skin measurement functions. For example, the proximity sensor measures not only proximity but also skin color information, while the HRM/PPG sensors measure both biometric data and skin pigmentation, eliminating the need for separate skin measuring sensors.
2Adaptability or versatility
If existing sensors are replaced with skin measuring sensors, then skin measurement capability is improved, but original sensor functions (heart rate measurement, proximity recognition) deteriorate
Solution Approach 1:
The patent makes existing sensors multi-functional so they can simultaneously perform their original functions and skin measurement. The proximity sensor continues to detect proximity while also measuring skin color, and the HRM/PPG sensors continue heart rate monitoring while also providing skin pigmentation data, thus maintaining reliability of original functions while adding new capability.
Solution Approach 2:
The patent merges skin measurement functionality with existing sensor operations. By combining the measurement functions of proximity sensors, HRM sensors, and PPG sensors with skin analysis capabilities, the system achieves both original sensor purposes and new skin measurement functionality through integrated operation.
