Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical stimulation and EEG devices require expert knowledge for safe operation, as they involve manual adjustment of stimulation intensity and attachment to a flexible strap or head cap, making them unsafe for non-experts to use in everyday life.
Innovation Solution
A wearable device equipped with a wearing identification unit using sensors to check the correct placement and user identification, ensuring safe operation by controlling the electrical stimulation or brain wave measurement only after proper wear is confirmed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual adjustment of stimulation intensity and direct attachment to flexible strap or head cap is used, then device functionality is achieved, but safety risk increases for non-expert users
Solution Approach 1:
The wearable device automatically detects user identity through biometric sensors and autonomously configures stimulation parameters based on pre-stored profiles, eliminating the need for manual adjustment by users. The device self-verify wearing state through sensor data and automatically adjusts operation accordingly, making safe operation accessible to non-experts.
Solution Approach 2:
The system pre-configures multiple sets of stimulation parameters (current intensity, frequency, waveform) corresponding to different user profiles and treatment conditions. Based on automatic user identification and wearing state detection, the system automatically selects and adjusts the appropriate parameter set, transforming complex manual parameter adjustment into automatic parameter selection.
2Measurement precision
If expert knowledge is required for operation, then stimulation precision is maintained, but user accessibility decreases
Solution Approach 1:
Expert-configured stimulation profiles and parameters are pre-stored in the device memory before use. User identity and corresponding treatment protocols are pre-programmed, allowing the device to automatically retrieve and execute the correct stimulation regimen without requiring real-time expert intervention, thus maintaining precision while improving accessibility.
Solution Approach 2:
The control unit acts as an intermediary between the user and the stimulation delivery system. It automatically processes sensor data, identifies user profiles, selects appropriate parameters, and controls electrode output, serving as an intelligent mediator that translates simple user actions into precise medical-grade stimulation without requiring user expertise.
3Reliability
If wearing state checking is added, then safety is improved, but device complexity increases
Solution Approach 1:
Existing sensors in the wearable device (accelerometers, gyroscopes, contact sensors) are multi-used for both motion tracking and wearing state verification. The same sensor array that monitors user activity also detects whether the device is properly positioned on the head, eliminating the need for separate verification hardware and reducing overall system complexity.
Solution Approach 2:
The wearing state detection function is merged with the existing motion sensing and user interface systems. The control unit integrates processing of wearing state data with other device functions, combining multiple purposes into unified control logic and software routines, thereby minimizing the increase in complexity while achieving comprehensive safety monitoring.
