Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nail printing technologies do not effectively utilize biological information related to blood flow to dynamically adjust and personalize nail designs based on a user's psychosomatic state, leading to a lack of tailored aesthetic and psychological benefits.
Innovation Solution
An information processing device and nail printing system that acquires biological information through video analysis of blood flow, determining nail designs to be printed based on this data, allowing for personalized and adaptive nail art that reflects the user's emotional and physiological state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If nail printing technology uses traditional methods without biological information integration, then the device complexity is low, but the adaptability and personalization capability are insufficient
Solution Approach 1:
The patent merges nail printing functionality with biological information acquisition and processing capabilities. The system integrates a video acquisition unit, pulse wave measurement unit, and nail design determination unit into a unified nail printing device, enabling it to simultaneously perform physiological measurement and personalized design generation without requiring separate external devices
Solution Approach 2:
The nail printing device is designed with multi-functionality to serve both as a printing device and a biological measurement device. The video acquisition unit and pulse wave measurement unit enable the device to gather physiological data while the nail design determination unit processes this data to generate personalized designs, making the device universally applicable for both measurement and creative output
2Measurement precision
If the system acquires biological information through video analysis, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical or optical measurement methods with video-based photoplethysmography. Instead of using separate sensors to measure pulse waves, the system uses a video acquisition unit to capture visual information and extracts pulse wave data through image processing, substituting mechanical measurement with optical/video-based measurement for higher precision
Solution Approach 2:
The patent introduces an intermediary processing layer between video acquisition and biological information extraction. The pulse wave measurement unit acts as an intermediary that processes video data to extract pulse wave information, and the nail design determination unit further processes this to generate designs. This intermediary processing enables precise biological measurement through video analysis without direct complex mechanical intervention
3Adaptability or versatility
If the system processes biological information to determine nail designs, then the adaptability and personalization improve, but the processing time increases
Solution Approach 1:
The patent implements preliminary action by pre-establishing correspondence relationships between pulse wave characteristics and nail design parameters. The system pre-defines how specific pulse wave patterns (indicating physiological states) translate into design recommendations, allowing for rapid design determination without time-consuming real-time analysis during the actual nail printing process
Applied Scientific Principles
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 system provides nail designs that are tailored to the user's psychosomatic state, offering aesthetic appeal and psychological benefits such as stress relief and motivation enhancement by using video-based photoplethysmography to measure blood flow without contact, reducing noise and saving time and labor in pulse wave measurement.
