Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless power supply is used for implanted medical devices, then physical connections are eliminated and patient comfort is improved, but control according to the state of the living body cannot be achieved
Solution Approach 1:
The system incorporates a feedback mechanism where sensors detect living body information (such as blood pressure, heart rate, or other physiological parameters), this information is transmitted wirelessly to the control device, which then adjusts the stimulation parameters accordingly. This closed-loop feedback enables the system to adapt to the patient's physiological state while maintaining wireless operation.
Solution Approach 2:
The implanted device is equipped with sensors that automatically monitor the patient's physiological state and the control algorithm autonomously adjusts stimulation parameters based on this data, reducing the need for manual intervention and enabling self-regulating wireless control adapted to living body conditions.
2Device complexity
If manual control of implanted devices is used, then control according to living body state is not achieved, but system complexity is reduced
Solution Approach 1:
The system replaces manual mechanical control with automated electronic control. Sensors electronically detect physiological parameters, wireless communication electronically transmits data, and control algorithms electronically adjust stimulation parameters, substituting the manual mechanical adjustment process with an automated electronic system that adapts to living body state.
3Adaptability or versatility
If sensors and analysis units are added to enable living body-based control, then adaptability is improved, but device complexity increases
Solution Approach 1:
The control device is designed as a multi-functional integrated system that combines sensing capabilities, wireless communication, data processing, and stimulation control in a single device. This universal design allows the same device to perform multiple functions (monitoring physiological parameters, communicating wirelessly, analyzing data, and controlling stimulation) without requiring separate dedicated components for each function, thereby reducing overall system complexity while maintaining adaptability.
