Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large devices with batteries and long leads are used for neuromodulation, then nerve stimulation can be achieved, but the devices require invasive implantation, have high costs, and require periodic battery replacement
Solution Approach 1:
The patent extracts and removes the battery and power management components from the implantable neuromodulation device, eliminating the need for invasive implantation of large devices and periodic battery replacement. The device is powered wirelessly through inductive coupling from an external power source, allowing for a much smaller, simpler implantable unit that can be inserted percutaneously without surgical intervention.
Solution Approach 2:
The external power source serves multiple functions: it provides wireless power transmission to the implantable device, enables programmable control of stimulation parameters, and allows for device configuration and monitoring. This multi-functional external unit eliminates the need for separate battery, programmer, and controller components that would otherwise need to be integrated into the implantable device.
2Reliability
If large devices with long leads are used, then nerve stimulation is possible, but precision in targeting specific nerves is reduced and unwanted nerve stimulation occurs
Solution Approach 1:
The patent divides the neuromodulation system into separate functional components: a small implantable unit with electrodes positioned near the target nerve, and an external power source with control circuitry. This segmentation allows the implantable device to be minimally invasive while the external unit handles complex functions, improving both targeting precision and overall system efficacy.
Solution Approach 2:
The system enables programmable control of stimulation parameters (amplitude, pulse width, frequency, duty cycle) from the external power source, allowing precise adjustment of electrical characteristics to target specific nerves while avoiding unwanted stimulation of adjacent structures. The ability to modify parameters without surgical intervention optimizes therapy precision.
3Reliability
If invasive implantation is performed, then neuromodulation treatment can be delivered, but costs increase and surgical risks are introduced
Solution Approach 1:
By removing the battery and power management components from the implantable device and placing them in an external unit, the patent enables percutaneous insertion of a small, simple implantable device without surgical implantation. This dramatically simplifies the manufacturing and deployment process while maintaining reliable treatment delivery through wireless power transmission.
4Device complexity
If wireless power transmission is used, then device size is reduced and invasive implantation is avoided, but power budget becomes more restrictive
Solution Approach 1:
The system uses periodic inductive power transmission from the external power source to the implantable device, with the external unit controlling the timing and duration of power delivery. This periodic action allows for efficient power management, transmitting energy only when needed and optimizing the power budget for the wireless system.
