Solution Overview
Problem
Existing mobile healthcare systems require separate portable measurement apparatuses, making them inconvenient to carry and difficult to use for various tests, as they increase the size and thickness of mobile devices.
Innovation Solution
Integrating a physiological signal measurement apparatus into the battery cover of a mobile device, which includes conductive electrodes, a control unit, and a communication unit, allowing for detachable attachment and power supply from the mobile device, enabling measurement of physiological signals without increasing the device's size or thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate portable measurement apparatus is used for physiological signal measurement, then measurement functionality is provided, but the device size and thickness increase
Solution Approach 1:
The patent combines the physiological signal measurement apparatus with the mobile device by integrating electrodes into the battery cover, which is a component already present in the mobile device. This merging approach allows the measurement functionality to be provided without adding separate external devices, thereby avoiding increases in overall device size and thickness while maintaining adaptability for health monitoring
Solution Approach 2:
The measurement apparatus is nested within the existing structure of the mobile device by placing electrodes in the battery cover that attaches to the mobile device. This nesting approach allows the measurement functionality to be housed within the existing form factor of the mobile device, preventing any increase in the device's external dimensions while still providing comprehensive measurement capabilities
2Adaptability or versatility
If a separate portable measurement apparatus is carried, then physiological signal measurement is enabled, but convenience and ease of operation decrease
Solution Approach 1:
By merging the measurement apparatus with the mobile device through the battery cover integration, the system eliminates the need for users to carry separate measurement devices. The mobile device itself becomes the measurement apparatus, providing physiological signal measurement capabilities while maintaining the convenience of using a single familiar device that users already carry daily
Solution Approach 2:
The mobile device is transformed into a multi-functional device that serves both as a communication device and as a physiological signal measurement apparatus. By integrating various sensors and measurement capabilities into the mobile device, it can perform multiple functions including ECG measurement, body fat measurement, and other health monitoring tasks, eliminating the need for multiple separate devices and improving ease of operation
