Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transbody communication is performed in noisy transmission environments, then communication can be established, but errors and data corruption occur
Solution Approach 1:
The patent converts the harmful noise in the transmission environment into a beneficial factor by using noise-resistant modulation schemes and spread spectrum techniques that actually utilize the noisy channel characteristics to achieve more reliable communication. The system transforms the adverse noisy conditions into opportunities for enhanced signal detection and error correction.
Solution Approach 2:
The patent employs parameter changes by dynamically adjusting communication parameters such as modulation depth, frequency hopping patterns, and power levels based on the detected noise conditions. This allows the system to adapt to varying noise environments and maintain reliable communication despite distortion and interference.
2Reliability
If high power is consumed by communication devices, then signal transmission can be maintained, but device life cycle becomes short
Solution Approach 1:
The patent implements periodic action through duty-cycled communication where devices transmit and receive signals in periodic bursts rather than continuously. This allows the in vivo transmitter to remain inactive for extended periods, conserving battery power while maintaining reliable communication when needed. The system uses periodic beacon signals and scheduled data transmission to achieve this balance.
Solution Approach 2:
The patent uses parameter changes by dynamically adjusting power output based on communication needs, distance, and signal quality requirements. The system transitions between different power states (high power for critical transmissions, low power for idle periods) to optimize the balance between transmission quality and battery life extension.
3Volume of moving object
If communication devices are made small for in vivo implantation, then device size is reduced, but power consumption management becomes more challenging
Solution Approach 1:
The patent applies segmentation by dividing the communication system into separate functional components: an ultra-small in vivo transmitter implant and an external receiver unit. This segmentation allows the implanted device to be minimized in size while the power management and complex processing functions are distributed to the external unit, reducing the power burden on the implanted battery.
Solution Approach 2:
The patent uses periodic action with the in vivo transmitter operating in brief, periodic transmission bursts separated by long idle periods. This duty-cycled operation minimizes the average power consumption of the implanted device, allowing it to maintain functionality with a small battery capacity that would be insufficient for continuous operation.
