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 and independence are limited due to requiring assistance 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 detects and configures connected devices, and users can autonomously switch between multiple devices using neural commands, making the system self-sufficient for daily operation.
Solution Approach 2:
The BCI system is designed to control multiple different types of external devices (computers, tablets, smart home devices) through a single unified interface. The system automatically adapts to different device types and protocols, providing universal control capability that eliminates the need for device-specific setup procedures.
2Adaptability or versatility
If BCI systems control multiple external devices, then user independence increases, but security risks arise from unauthorized access
Solution Approach 1:
The system continuously monitors connection status and authentication states of external devices. It provides real-time feedback on which devices are authorized and actively connected, allowing users to manage security by reviewing and controlling access permissions through neural commands.
Solution Approach 2:
The BCI system acts as an intermediary layer between users and external devices, managing authentication and authorization protocols. It verifies device identities and user permissions before establishing control connections, providing security mediation that protects both the user and connected devices from unauthorized access.
3Duration of action of stationary object
If processing is distributed to portable SCU, then longevity of implanted components is extended, but system architecture complexity increases
Solution Approach 1:
The BCI system is segmented into distinct functional modules: an implanted component for neural signal acquisition and a portable SCU for signal processing and device control. This segmentation allows the implanted component to remain simple and long-lasting while offloading complex processing tasks to the portable unit.
Solution Approach 2:
The portable SCU serves as an intermediary processing unit that receives raw neural signals from the implanted component, performs algorithmic processing and decoding, then transmits control commands to external devices. This intermediary architecture protects the implanted component from complexity while enabling advanced functionality.
