Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electroencephalogram acquisition unit and controller are integrated into the eyeshade, then the functionality for monitoring brain states and temperature control is improved, but the device complexity increases
Solution Approach 1:
The patent combines the electroencephalogram acquisition unit, controller, and heating unit into a single integrated eyeshade device. The controller serves multiple functions by receiving brain electrical signals from the electroencephalogram acquisition unit and controlling the heating unit based on these signals, thereby reducing the need for separate devices and simplifying the overall system architecture.
Solution Approach 2:
The controller is designed as a multi-functional component that performs both signal reception from the electroencephalogram acquisition unit and control of the heating unit. This universal controller reduces the number of separate components needed, thereby improving functionality while managing device complexity through consolidation of control functions.
2Ease of repair
If the controller is detachably coupled to the electroencephalogram acquisition unit, then the ease of repair and maintenance is improved, but the reliability of signal transmission may worsen
Solution Approach 1:
The controller is designed as a detachable component that can be separated from the electroencephalogram acquisition unit. This segmentation allows the controller to be easily removed for repair, maintenance, or replacement without affecting the entire eyeshade device. The detachable connection is designed to maintain reliable signal transmission when coupled, while enabling easy access to the controller for servicing.
3Measurement precision
If the flexible circuit board passes through the opening in the eyeshade main body to contact the forehead, then the measurement precision of brain electrical signals is improved, but the ease of operation and comfort may worsen
Solution Approach 1:
The patent employs a flexible circuit board that can bend and conform to the contours of the wearer's head and forehead. This flexibility allows the circuit board to maintain close contact with the forehead for accurate signal detection while adapting to individual head shapes and movements, thereby preserving measurement precision without significantly compromising wearer comfort or ease of operation.
