Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current EEG and ECG measurement devices operate as standalone systems, lacking integration of both functionalities, which limits their application, usability, and increases healthcare costs due to separate designs and operation circuits.
Innovation Solution
A dual-functional measurement device incorporating both EEG and ECG capabilities, featuring a shell design with switchable contact configurations and signal processing circuits for amplifying and filtering signals, allowing for EEG and ECG mode operation with wireless signal transmission to medical centers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If EEG and ECG functionalities are integrated into a single device, then device versatility and user convenience are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines EEG and ECG measurement functionalities into a single device by integrating separate measurement circuits for both brainwave and cardiac signal detection within one housing unit, allowing dual-functional operation from a single product
Solution Approach 2:
The device is designed with universal applicability by incorporating multiple measurement modes (EEG and ECG) that can be switched between, enabling one device to serve multiple medical monitoring purposes rather than requiring separate dedicated devices
2Reliability
If separate EEG and ECG devices are used, then device reliability and measurement precision are maintained, but healthcare costs and operational complexity increase
Solution Approach 1:
The patent merges multiple measurement functions into one device while maintaining separate dedicated circuits for EEG and ECG, ensuring that each measurement type retains its reliability and precision requirements through independent signal processing paths
3Volume of moving object
If device size is minimized through integration, then portability and ease of operation are improved, but manufacturing precision and assembly difficulty increase
Solution Approach 1:
The device is divided into separable components including a first shell containing ECG contacts and a second shell containing EEG contacts, which can be assembled together through a fixing device, allowing modular manufacturing and assembly while maintaining compact overall size

AI summary
A measurement device with electroencephalography (EEG) and electrocardiography (ECG) functionalities includes a first shell having ECG functionality and a second shell. The first shell includes a first contact and a second contact located at a first side of the first shell; and a third contact located at a second side of the first shell, wherein the second side of the first shell is substantially opposite to the first side of the first shell. The second shell includes a fixing device, for connecting with and fixing on the first shell; and a fourth contact, a fifth contact and a sixth contact, located at a first side of the second shell, for electrically connecting with the first contact, the second contact and the third contact respectively when the first shell is connected to and fixed on the fixing device, in order to perform EEG measurement.
