Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for transmitting measurement data from portable medical devices require interfaces and format transformation software, which are device-specific and cumbersome, especially when using mobile phones with varying transmission methods.
Innovation Solution
A data processing system that includes a measurement apparatus with a display screen for showing measurement data as bar codes, two-dimensional codes, or composite codes, and a terminal with image pickup capabilities to capture and transmit these codes, allowing easy data capture and transmission without the need for device-specific interfaces or software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement data is transmitted using communication equipment with device-specific interfaces and format transformation software, then data transmission can be achieved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent applies the copying principle by displaying measurement data as visual codes (bar codes, two-dimensional codes, or composite codes) on the measurement apparatus display screen. The terminal device captures these codes using its image pickup device, effectively copying the data from the measurement apparatus without requiring direct communication interfaces or format transformation software. This eliminates the need for device-specific connection interfaces while maintaining reliable data transmission capability.
Solution Approach 2:
The patent replaces the mechanical/connection-based data transmission system (wired or wireless interfaces requiring physical connection and protocol matching) with an optical system. The measurement data is converted into visual code images displayed on the screen, and the terminal device uses its image pickup device (camera) to capture these images. This substitution eliminates the need for communication interfaces, cables, and format transformation software, significantly reducing device complexity.
2Adaptability or versatility
If device-specific adaptors are developed for each mobile phone company and product, then data transmission compatibility is achieved, but manufacturing costs and development time increase
Solution Approach 1:
The patent applies the universality principle by using a standardized visual code display method that can be captured by any terminal device with an image pickup function. The measurement apparatus displays measurement data as bar codes, two-dimensional codes, or composite codes using standard encoding formats that are universally readable. This universal approach eliminates the need to develop device-specific adaptors for different mobile phone companies or products, as any terminal device with camera functionality can capture and read these codes, achieving broad compatibility without additional development costs.
3Reliability
If measurement data is transformed into transmittable format using specialized software, then data can be transmitted, but ease of operation decreases
Solution Approach 1:
The patent applies the self-service principle by enabling the measurement apparatus to automatically display its measurement data in a visually encodable format (bar code, two-dimensional code, or composite code) without requiring user intervention for format transformation. The terminal device then captures this displayed code using its image pickup device and automatically processes it for transmission. This eliminates the need for users to manually transform data formats or operate complex software, making the data transmission process as simple as taking a photograph, thereby significantly improving ease of operation.
