Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional shunts are used to drain CSF, then intracranial pressure can be reduced, but precise regulation and monitoring of brain activity cannot be achieved
Solution Approach 1:
The patent combines multiple functions (CSF drainage, pressure sensing, optical emission for optogenetics, and electrical electrode contact) into a single integrated implantable device. This merging allows simultaneous achievement of precise monitoring and treatment capabilities without requiring multiple separate devices, thereby improving measurement precision while managing device complexity through functional integration.
Solution Approach 2:
The implantable device is designed with multi-functionality, serving as both a drainage system for hydrocephalus and a monitoring/treatment system for neurological conditions. The single device performs CSF drainage, pressure measurement, optical stimulation, and electrical stimulation, enabling universal application across multiple neurological treatments and monitoring needs.
2Reliability
If invasive treatments are used to modulate neural activity, then treatment efficacy can be improved, but patient comfort and ambulatory capability deteriorate
Solution Approach 1:
The device enables ambulatory patients to receive continuous neural modulation and monitoring without requiring hospital visits. The implantable system performs self-contained functions including autonomous pressure regulation, continuous optical and electrical stimulation, and real-time monitoring, allowing patients to manage their conditions independently in outpatient settings.
Solution Approach 2:
The patent enables continuous, uninterrupted neural modulation and monitoring through the implantable device. Unlike intermittent hospital-based treatments, the system provides continuous optical emission, electrical stimulation, and pressure monitoring, ensuring uninterrupted therapeutic action and improving both treatment efficacy and patient comfort through sustained ambulatory care.
3Measurement precision
If frequent hospital visits are required for monitoring and treatment adjustments, then treatment precision can be maintained, but patient convenience and time efficiency deteriorate
Solution Approach 1:
The implantable device continuously monitors intracranial pressure and brain activity, providing real-time feedback that enables automatic or remotely-guided treatment adjustments. This continuous feedback loop maintains treatment precision without requiring frequent manual interventions at the hospital, thereby improving time efficiency while preserving measurement precision through automated monitoring and control.
