Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power transmission is regulated based on real-time power requirements, then power management efficiency is improved, but device complexity increases due to the need for separate data link communication
Solution Approach 1:
The system divides the communication function into two separate links: a power link for transmitting power signals and a data link for transmitting power requirement information. This segmentation allows independent optimization of each link's function, improving overall power management efficiency while keeping the complexity of individual links manageable.
Solution Approach 2:
The patent introduces a separate data link as an intermediary communication channel between the implantable medical device and external device. This intermediary allows the device to communicate its power requirements without interfering with the power transmission process, enabling efficient power regulation.
2Measurement precision
If separate data link is used for power requirement communication, then power regulation precision is improved, but loss of energy increases due to additional communication overhead
Solution Approach 1:
The patent extracts the power requirement communication function from the power transmission link and places it in a separate data link. This extraction allows the power link to focus solely on efficient power transmission while the data link handles communication, improving power regulation precision without significantly increasing energy loss.
Solution Approach 2:
The implantable medical device autonomously monitors its own power requirements and communicates them through the data link, eliminating the need for external monitoring systems. This self-service approach improves measurement precision while minimizing the energy overhead of communication.
3Reliability
If real-time power adjustment is implemented, then reliability of device operation is improved, but device complexity increases due to continuous monitoring and regulation
Solution Approach 1:
The system implements a feedback mechanism where the implantable medical device continuously monitors its power requirements and communicates them to the external device through the data link. The external device adjusts power transmission based on this feedback, improving operational reliability through continuous adaptation.
Solution Approach 2:
The patent introduces dynamic power adjustment capabilities allowing the system to adapt to changing power requirements in real-time. The separate data link enables dynamic communication of power requirements, and the power link responds dynamically by adjusting transmission parameters to match actual device needs.
