Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients with chronic diseases often forget to carry their in-vitro diagnosis (IVD) devices, leading to missed health status monitoring opportunities due to the need for standalone devices.
Innovation Solution
A mobile device accessory system that includes a test strip adapter, phone adapter, and coupler, allowing mobile devices to measure test strip characteristics using their display panel and image/light sensor, enabling accurate physiological parameter measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If patients use standalone IVD devices for blood glucose monitoring, then measurement functionality is available, but portability and ease of carrying is reduced
Solution Approach 1:
The patent combines the IVD measurement functionality with a mobile device by integrating a test strip adapter, phone adapter, and coupler system. The mobile device's display panel serves as the light source and image sensor captures the test strip characteristics, merging multiple functions into a single portable system that patients can easily carry in their pockets.
Solution Approach 2:
The mobile device is adapted to perform multiple functions: it serves as both the computational platform and the optical measurement system. The accessory system allows the mobile device to function as a standalone IVD device while maintaining its original communication and computing capabilities, enabling one device to serve multiple purposes.
2Measurement precision
If test strip adapters are designed for specific test strip types, then measurement accuracy is improved, but compatibility with different test strip types is reduced
Solution Approach 1:
The system divides the adapter into modular components: a test strip adapter specific to each test strip type, a universal phone adapter, and a coupler. This segmentation allows the specific test strip adapter to ensure measurement accuracy for its designated test strip type, while the universal components provide compatibility across different test strip types through the standardized coupler interface.
Solution Approach 2:
The coupler acts as an intermediary component that bridges the specific test strip adapter and the universal phone adapter. It provides a standardized connection interface that allows different test strip types to be measured by the same mobile device system, maintaining measurement accuracy through proper optical alignment while enabling versatility.
3Reliability
If phone adapters are customized for specific mobile device models, then connection stability is improved, but compatibility with different mobile device models is reduced
Solution Approach 1:
The adapter system is segmented into a model-specific phone adapter component and a universal coupler component. Each phone adapter is customized for a specific mobile device model to ensure stable connection and proper alignment, while the universal coupler provides the standardized interface that enables compatibility across different mobile device models through the same test strip adapter interface.
