Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of intracranial EEG sensors is increased to improve diagnostic precision, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The device is divided into modular sensor elements that can be independently configured and combined. Each sensor element contains integrated circuitry and contacts, allowing the system to be scaled by adding or removing modules rather than redesigning the entire system, thus managing complexity while enabling increased measurement precision through additional sensors.
Solution Approach 2:
The sensor elements are designed with universal interfaces and standardized configurations that can be used across multiple channels and positions. This multi-functionality allows the same basic module to serve multiple purposes, reducing overall device complexity while enabling expanded diagnostic capabilities through increased sensor count.
2Measurement precision
If the number of intracranial EEG sensors is increased to improve diagnostic precision, then measurement precision is improved, but the number of components increases
Solution Approach 1:
Multiple functional components are merged into integrated sensor elements. Each element combines EEG sensing contacts, temperature sensors, and control circuitry into a single modular unit. This merging reduces the total number of separate components that would otherwise be required, while still enabling increased diagnostic precision through multiple sensors.
3Reliability
If active cooling is applied to control seizures, then therapeutic effect is improved, but energy consumption increases
Solution Approach 1:
The cooling system operates in periodic cycles rather than continuously. The thermoelectric cooling elements are activated during seizure events to provide therapeutic effect, then deactivated during inter-ictal periods. This periodic operation maintains seizure control effectiveness while significantly reducing average energy consumption compared to continuous cooling.
Solution Approach 2:
Cooling is applied locally only to the specific brain regions where seizures are detected, rather than cooling the entire brain. This localized approach concentrates energy consumption where it is most therapeutically needed, improving seizure control effectiveness while minimizing overall energy usage.
4Measurement precision
If multiple temperature sensors are distributed in the brain, then temperature monitoring precision is improved, but device complexity increases
Solution Approach 1:
The temperature monitoring system is segmented into distributed sensor elements that are integrated with the EEG sensor modules. Each sensor element independently measures local temperature, and the data is aggregated by the control circuitry. This segmentation enables precise spatial temperature mapping while managing system complexity through modular architecture.
Solution Approach 2:
The sensor elements are designed to autonomously perform both EEG recording and temperature sensing functions without requiring separate dedicated systems. The integrated design allows each module to self-manage its sensing and communication functions, reducing overall device complexity while enabling multiple measurement capabilities including precise temperature monitoring.
