Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used for data transmission, then data access is improved, but power consumption increases
Solution Approach 1:
The communication module operates periodically rather than continuously, transmitting data at predetermined intervals or when specific conditions are met. This periodic operation enables data access functionality while significantly reducing overall power consumption compared to continuous communication.
Solution Approach 2:
The sensor device automatically manages its communication needs by detecting when data transmission is necessary based on sensor readings or time intervals, eliminating the need for external intervention. This self-service approach optimizes power usage by activating communication only when required.
2Reliability
If the sensor is implanted under the skin, then sensing capability is improved, but accessibility for maintenance deteriorates
Solution Approach 1:
The sensor device is designed as a self-contained unit with an implanted power source that provides sufficient operational duration without requiring physical access for battery replacement. The device autonomously manages its power supply and operational lifecycle, eliminating the need for surgical intervention for maintenance.
Solution Approach 2:
The device incorporates a reusable power source with extended operational duration, dynamically managing power consumption to ensure the device remains functional throughout its intended lifecycle without requiring physical access for power supply maintenance.
3Adaptability or versatility
If wireless communication is enabled, then data transmission capability is improved, but device complexity increases
Solution Approach 1:
The communication module is integrated into the sensor device to provide data transmission capabilities, combining multiple functions (sensing, processing, and communication) into a single unified device. This integration enables data transmission while managing overall device complexity through functional consolidation.
4Duration of action of moving object
If the power source is implanted, then operational duration is improved, but infection risk increases
Solution Approach 1:
The power source is completely implanted within the sensor device, eliminating the need for external connections or frequent surgical interventions. This self-contained design extends operational duration while reducing infection risk by minimizing the frequency and necessity of surgical procedures.
Solution Approach 2:
The power source is designed with extended operational duration to cover the entire intended lifecycle of the implantable sensor, dynamically managing energy consumption to ensure continuous operation without requiring physical access or creating opportunities for infection.
