Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical devices for home use that measure blood flow and voluptuousness information are either expensive or difficult to install and operate, with separate devices using similar IR light methods but lacking integration for simultaneous measurement.
Innovation Solution
An apparatus and method that integrate a light-emitting device, a light-receiving device, and an image sensor with a controller to selectively drive the sensors based on distance, allowing for simultaneous acquisition of blood flow and voluptuousness information using reflected light, with the option to display and transmit this information on a transparent display or external device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate devices are used for measuring blood flow and voluptuousness information, then measurement functions are specialized, but device complexity and installation difficulty increase
Solution Approach 1:
The patent combines separate blood flow measurement device and voluptuousness measurement device into a single integrated apparatus. The light emitting device, light receiving device, and image sensor are merged into one system that can perform both measurement functions simultaneously or alternatively, reducing the number of separate devices needed while maintaining specialized measurement capabilities
Solution Approach 2:
The integrated apparatus is designed with multi-functionality to perform both blood flow measurement and voluptuousness measurement. The controller selectively activates different sensing modes based on the measurement type required, allowing a single device to replace multiple specialized devices and simplify the overall system
2Measurement precision
If 3D body scanner is used for measuring voluptuousness, then measurement accuracy is high, but cost and installation difficulty increase
Solution Approach 1:
The patent replaces expensive 3D body scanners with more affordable sensing components including light emitting devices, light receiving devices, and image sensors. This substitution maintains adequate measurement precision for voluptuousness while significantly reducing cost and simplifying installation for home use environments
3Measurement precision
If transmission type detection method is used for blood flow measurement, then blood flow detection accuracy is high, but device structure becomes complex
Solution Approach 1:
The patent designs the light receiving device to function in multiple modes - it can operate as a transmission type detector for high-accuracy blood flow measurement when needed, or as a reflected light detector for other measurement scenarios. This multi-functional design maintains measurement accuracy while reducing structural complexity by using a single sensor arrangement for multiple purposes
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
Enables comprehensive health assessment by simultaneously measuring blood flow and voluptuousness information, improving user convenience and reducing costs by integrating sensors for both functions in a single device.
Implementation Method 1
blood, bones, or tissues absorb the light, and the other portion of the light passes through the blood, the bones, or the tissues and then reaches a light receiver
Implementation Method 2
detect reflected light reflected from the object
Implementation Method 3
detect reflected light reflected from the object
Implementation Method 4
The TOF method is the most typical and basic distance measuring method and measures a difference between a time when pulses are emitted and a time when reflected waves are received in order to acquire a distance
