Solution Overview
Problem
Current physiological measurement instruments face issues with incorrect observation and input of measurement values, especially in older users, due to inconsistent Bluetooth communication protocols, leading to a need for improved methods and equipment for processing image information.
Innovation Solution
A method and equipment that utilize a terminal device with a camera and cloud server to recognize and process measurement result images, eliminating the need for manual input of measurement values by transmitting images to the cloud server for recognition and validation, and storing the recognized results for use in application programs, compatible with various Bluetooth protocols and devices without communication functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual input of measurement values is used, then device complexity is reduced, but measurement precision and reliability deteriorate due to incorrect observation and input by users
Solution Approach 1:
The patent uses image copying technology where the measurement device's display screen is photographed by a camera to create a digital copy of the measurement value. This copy is then processed through OCR recognition to extract the actual measurement value, eliminating the need for manual transcription and ensuring accuracy while maintaining simple device architecture.
2Reliability
If Bluetooth communication modules are added to all measurement devices, then information transmission reliability improves, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent introduces an intermediary image processing system consisting of a camera, image processing unit, and OCR recognition module. This intermediary captures the measurement value from the device display and transmits it to the terminal device, serving as a universal communication bridge that works with any measurement device regardless of its native communication protocol, thus avoiding the need to add Bluetooth modules to all devices.
Solution Approach 2:
The image-based communication system serves as a universal interface that can extract measurement values from any measurement device display, making the system compatible with devices having different Bluetooth protocols or no communication functions, thereby achieving multi-functionality without increasing individual device complexity.
3Adaptability or versatility
If different application programs are designed for different Bluetooth protocols, then adaptability to various devices improves, but ease of operation deteriorates due to the need to match protocols
Solution Approach 1:
By capturing the measurement value as an image and using OCR recognition, the system creates a protocol-independent data extraction method. The terminal device's application program only needs to handle image processing and text recognition, not multiple Bluetooth protocols, thus maintaining adaptability while greatly simplifying operation.
