Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for controlling vehicle-mounted convenient devices, such as power windows and entertainment systems, require user engagement through gestures or voice commands, which can be inconvenient, especially for rear-seat passengers due to the distance from the devices.
Innovation Solution
A system utilizing an EEG sensor to measure brain signals, an EEG analyzer to interpret these signals, and a controller to operate vehicle devices based on the user's intentions, with a light source emitting specific frequencies and colors to facilitate device control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture or voice recognition devices are used to control convenient devices, then user convenience is improved, but the distance requirement between user and control device creates operational difficulty for rear-seat passengers
Solution Approach 1:
The patent replaces mechanical gesture recognition and voice command systems with an EEG-based brain-computer interface system. The EEG sensor detects brain signals directly from the user's head, eliminating the need for physical gestures or voice commands and removing distance constraints between the user and control device. This allows rear-seat passengers to operate convenient devices with the same ease as front-seat passengers.
2Ease of operation
If EEG-based control is implemented, then ease of operation is improved for all users regardless of position, but device complexity increases due to additional sensors and signal processing requirements
Solution Approach 1:
The patent integrates the EEG sensor into the existing seat structure, making it a multi-functional component that provides both seating support and brain signal detection. The controller is designed to handle multiple functions including EEG signal processing, gesture recognition, and convenient device control, reducing the need for separate dedicated systems and minimizing overall device complexity.
