Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional electrophysiology equipment is used, then measurement precision is maintained, but device complexity and cost increase significantly
Solution Approach 1:
The patent uses disposable, low-cost single-board computers (Raspberry Pi) instead of expensive, complex traditional electrophysiology equipment. These inexpensive devices are configured to perform neural recording tasks, demonstrating that cheap computing hardware can replace costly specialized equipment while maintaining functional capability.
Solution Approach 2:
The single-board computer serves multiple functions: it acts as the recording device, processes data locally, communicates via multiple protocols (Bluetooth, WiFi, USB), and can be configured for different experimental setups. This multi-functional approach replaces multiple specialized devices with a single versatile platform.
2Measurement precision
If manual supervision is used for data management, then measurement precision is maintained, but productivity decreases
Solution Approach 1:
The system performs automated data management including local buffering, protocol conversion, and cloud upload without requiring manual intervention. The single-board computer autonomously handles data acquisition, processing, and transmission, eliminating the need for continuous manual supervision while maintaining data quality through programmed quality control measures.
Solution Approach 2:
The system implements automated feedback loops for data quality monitoring and system status tracking. Data is continuously monitored, processed, and uploaded with automatic error handling and retransmission capabilities, ensuring data quality while reducing manual oversight requirements.
3Reliability
If expensive equipment is used, then reliability is improved, but ease of manufacture worsens
Solution Approach 1:
The patent deliberately chooses inexpensive, commercially available single-board computers that can be easily manufactured and deployed. These devices are so affordable that multiple units can be distributed widely, enabling easier manufacture and deployment compared to expensive specialized equipment while maintaining sufficient reliability for research applications.
Solution Approach 2:
The system uses standardized, mass-produced single-board computers that are manufactured in large quantities through established supply chains. This copying approach of using off-the-shelf hardware rather than custom-built equipment significantly improves ease of manufacture and accessibility while maintaining functional reliability.
4Measurement precision
If local data storage is used, then measurement precision is maintained, but loss of time increases due to manual data transfer
Solution Approach 1:
The system implements continuous automated data upload to cloud storage during and after recording sessions. Data flows continuously from the single-board computer through local buffering to cloud repositories without interruption, eliminating the need for separate manual data transfer steps and reducing overall data processing time while maintaining data integrity through continuous verification.
Solution Approach 2:
The system performs preliminary data processing, filtering, and formatting locally before upload, and pre-configures cloud storage structures in advance. This preliminary action reduces the time needed for post-experiment data handling by preparing data and storage infrastructure beforehand, while local buffering ensures data integrity is maintained throughout the process.
