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 across various applications. Instead of requiring separate control systems for each application, a single universal switch module can be programmed to respond to neural signals by executing different commands for different applications, thereby achieving versatility without proportionally increasing system complexity
Solution Approach 2:
The system employs dynamic configuration capabilities where the mapping between neural signals and target tasks can be adjusted and reconfigured based on user needs and application requirements. This dynamic adaptability allows the system to evolve from rigid pre-defined controls to flexible, user-specific control schemes, improving versatility while maintaining manageable complexity through software-based reconfiguration
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 patent implements feedback mechanisms that collect and store data from multiple users' interactions with the BCI system across various applications. This accumulated data is used to refine and improve system performance, optimize signal processing algorithms, and enhance the matching between neural signals and appropriate target tasks, thereby systematically improving reliability while utilizing real-world usage information
3Adaptability or versatility
If a universal switch module is implemented to allow control of multiple applications, then versatility and user flexibility are enhanced, but the complexity of configuring and managing the system increases
Solution Approach 1:
The system incorporates automated configuration capabilities and user-friendly interfaces that guide users through the setup process. The universal switch module can automatically detect available applications and suggest appropriate control mappings, reducing the burden on users and medical caregivers while still providing comprehensive customization options for those who need them
