Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current BCI systems require users to perform task-relevant or task-irrelevant mental tasks to control pre-defined target tasks, then the system can achieve basic control functionality, but the versatility and adaptability of the system is limited
Solution Approach 1:
The patent implements a universal switch module that can be configured to control multiple different target tasks and end-applications. Instead of requiring separate control systems for each function, a single modular switch can be programmed to handle various commands (e.g., cursor control, device activation, software navigation), thereby improving versatility without proportionally increasing system complexity
Solution Approach 2:
The control system allows dynamic reconfiguration of the universal switch through programmable parameters. The switch can be adjusted to respond to different neural signals and control different functions based on user needs, enabling the system to adapt to varying tasks and applications while maintaining a consistent hardware architecture
2Reliability
If current BCI systems use pre-defined target tasks set by researchers, then the system can achieve controlled experimental conditions, but data accumulation for systemic improvement is prevented
Solution Approach 1:
The system incorporates data logging and feedback mechanisms that collect operational information from multiple users. This data is compiled and analyzed to identify patterns and improve system performance, creating a continuous improvement cycle where real-world usage data informs future system optimizations and parameter adjustments
Solution Approach 2:
The universal switch module enables users to independently configure and control a variety of end-applications without requiring researcher intervention for each new application. The system's programmable nature allows it to serve itself by adapting to different use cases through software configuration rather than hardware redesign
3Adaptability or versatility
If a universal switch module is implemented to allow control of multiple end-applications, then system adaptability is improved, but the complexity of configuring and managing the system increases
Solution Approach 1:
The control system is divided into modular components, with the universal switch module serving as a discrete, configurable unit. Each module can be independently programmed and configured for specific functions, making the overall complex system manageable through modular design principles
