Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wired EEG systems are used, then measurement precision is maintained, but device complexity and ease of operation deteriorate due to multiple electrodes, wires, and synchronization requirements
Solution Approach 1:
The patent combines multiple electrodes and associated electronics into a single integrated wireless sensor unit. This merging eliminates the need for separate wire connections and simplifies the overall system architecture, allowing non-experts to easily set up EEG monitoring without dealing with complex wiring and synchronization protocols.
Solution Approach 2:
The patent replaces the mechanical wire-based connection system with wireless communication technology. This substitution eliminates physical wires and connectors, significantly reducing setup complexity and making the system easier to operate while maintaining signal transmission capability.
2Adaptability or versatility
If conventional wired EEG systems are used, then measurement precision is maintained, but accessibility worsens due to availability only in large tertiary hospitals
Solution Approach 1:
The patent employs disposable wireless EEG sensors that can be easily discarded after use. This approach reduces the cost and complexity of sterilization and maintenance infrastructure, enabling deployment in resource-limited settings such as rural clinics and community hospitals while maintaining measurement quality through factory-calibrated sensors.
Solution Approach 2:
The wireless EEG sensor system is designed to be universally applicable across different healthcare settings, from large tertiary hospitals to small rural clinics. The system's portability, ease of setup, and lack of infrastructure requirements make it adaptable to diverse environments while maintaining measurement precision.
3Measurement precision
If multiple electrodes are used for accurate EEG measurement, then measurement precision improves, but ease of operation worsens due to placement and synchronization requirements
Solution Approach 1:
The patent integrates multiple electrodes into a single wireless sensor unit, maintaining the ability to capture multiple EEG signals while eliminating the need for separate placement and wiring of each electrode. This merging simplifies the setup process to a single placement action while preserving measurement precision through internal electrode arrays.
