Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a typical BCI system uses external devices and wired connections for processing brain signals, then data processing capability is sufficient, but system reliability deteriorates due to multiple points of failure from damaged wires
Solution Approach 1:
The patent integrates the brain signal processing capabilities directly into the headset device itself, merging what were previously separate external processing devices into a unified integrated system. This eliminates multiple wired connections and external components that could fail, thereby improving reliability while maintaining sufficient processing capability through on-device computation.
Solution Approach 2:
The patent extracts the essential processing functions from external devices and embeds them directly into the headset. By taking out only the necessary processing capabilities and integrating them into the wearable device, the system eliminates dependency on external equipment and wired connections, reducing failure points while preserving adequate processing power.
2Ease of operation
If a typical BCI system uses multiple wired connections and external devices, then processing capability is adequate, but ease of operation deteriorates due to time-intensive setup and location dependency
Solution Approach 1:
The patent enables the headset to function as a self-sufficient device with integrated processing capabilities. The device performs brain signal processing independently without requiring external computers or complex setup procedures. This self-service approach eliminates location dependency and reduces setup time to minimal levels, allowing users to simply wear the device and begin operation immediately.
3Speed
If a typical BCI system uses external devices for feedback, then feedback accuracy is sufficient, but feedback delay increases due to transmission and processing time
Solution Approach 1:
The patent combines feedback generation and delivery functions within the headset itself, eliminating the time delay associated with transmitting signals to external devices and back. By merging processing and feedback delivery into a single integrated system, the device achieves rapid real-time feedback while maintaining accuracy through onboard processing capabilities.

AI summary
An apparatus, system, and method of a brain computer interface in a headset including an augmented reality display, one or more sensors, a processing module, at least one biofeedback device, and a battery. The interface may include a printed circuit board that has the sensors to read bio-signals, provides biofeedback, and performs the processing, analyzing, and mapping of bio-signals into output. The output provides feedback via stimulation of multiple sensory brain systems of a user, including audio and visual on the augmented reality display, or audio and haptic in terms of vibration patterns that a human user may feel. All together this forms a closed-loop system, by detecting the bio-signal, then providing sensory-feedback, which in turn enhances the bio-signal.
