Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional BCI systems provide limited autonomy to paralyzed individuals, requiring assistance for setup and device control, and lack the ability to autonomously switch between multiple devices and interact with a variety of external devices.
Innovation Solution
A BCI system with a fully implanted recording component and a portable signal control unit that includes a housing structure, power supply, electronic communications circuitry, and processor, capable of decoding brain signals and wirelessly communicating with multiple external devices using various communication modalities, including Bluetooth and Wi-Fi, with security features to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional BCI systems are used, then basic device control is enabled, but user autonomy is limited and caregiver assistance is required for setup and device switching
Solution Approach 1:
The BCI system enables users to independently perform setup, calibration, and device switching without caregiver assistance. The system automatically configures itself and adapts to user needs, eliminating the need for external help in system operation and management.
Solution Approach 2:
The BCI system is designed to control multiple different devices and perform various functions through a single unified interface. This multi-functional capability allows users to switch between devices autonomously without requiring separate control mechanisms for each device.
2Adaptability or versatility
If conventional BCI systems connect to a single computing device, then basic control is achieved, but the ability to autonomously switch between multiple devices is lost
Solution Approach 1:
The BCI system incorporates multiple communication modalities (Bluetooth, Wi-Fi, wired connections) and can seamlessly switch between different external devices. This universal communication capability enables autonomous device switching while maintaining system manageability through a unified control architecture.
Solution Approach 2:
The system dynamically adapts its communication mode and connected device based on user needs and environmental context. This dynamic switching capability allows the BCI to flexibly connect to different devices without requiring complex manual reconfiguration.
3Reliability
If security features are added to prevent unauthorized access, then system security is improved, but communication complexity increases
Solution Approach 1:
The system employs an intermediary authentication mechanism that verifies device identities and user authorization before establishing connections. This intermediary security layer protects against unauthorized access while maintaining relatively simple communication protocols through automated authentication procedures.
