Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless power and data transmission is implemented for sensor data collection, then ease of operation and adaptability are improved, but signal interference and power consumption increase
Solution Approach 1:
The patent divides the wireless communication into separate channels: one for power transmission and another for data transmission. This segmentation allows independent optimization of each channel, reducing signal interference between power and data signals while maintaining ease of wireless operation.
Solution Approach 2:
The patent introduces intermediary components such as shields and filters between power transmission and data transmission paths. These intermediaries act as mediators that block or reduce signal interference while allowing the wireless power and data transmission to function independently.
2Adaptability or versatility
If wireless power and data transmission is implemented, then adaptability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic transmission cycles where power and data are transmitted in alternating intervals rather than continuously. This periodic action reduces overall power consumption while maintaining wireless adaptability, as the system can enter low-power states between transmission cycles.
Solution Approach 2:
The patent employs dynamic power management that adjusts transmission power levels based on actual needs, distance, and environmental conditions. This dynamic adaptation allows the system to maintain versatility while minimizing power consumption by using only the necessary power level at any given moment.
3Measurement precision
If multiple sensors are monitored over time to detect tissue characteristics, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensor functions into integrated sensor arrays that can simultaneously monitor various tissue characteristics. This merging reduces device complexity by consolidating what would otherwise be separate monitoring systems into a unified platform.
Solution Approach 2:
The patent designs sensors with multi-functional capabilities that can detect different tissue characteristics (mechanical, electrical, thermal) using the same hardware platform. This universality allows precise multi-parameter monitoring without proportionally increasing device complexity.
