Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional implantable devices with batteries and long conduits are used, then reliable power supply and signal transmission are achieved, but device size becomes large and implantation becomes invasive
Solution Approach 1:
The patent extracts the battery and power management components from the implantable device, placing them in an external device instead. This allows the implantable device to be miniaturized while maintaining reliable power supply through wireless energy transfer from the external device.
Solution Approach 2:
The patent introduces an external device as an intermediary that houses the battery and communicates with the implantable device through wireless energy transfer and data communication, enabling power supply without increasing implantable device volume.
2Measurement precision
If segmented electrodes are used for precise neuromodulation, then stimulation precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the electrode into multiple segments that can be independently controlled, allowing precise targeting of specific nerve fibers while reducing stimulation of surrounding tissues. Each segment can be activated selectively based on therapeutic needs.
Solution Approach 2:
The patent implements dynamic control of segmented electrodes through programmable activation patterns, where different segments can be activated in different sequences and combinations to optimize therapeutic effect and minimize side effects.
3Reliability
If high energy is delivered for effective pain treatment, then therapeutic effect is improved, but unwanted stimulation of surrounding tissues increases
Solution Approach 1:
The patent applies local quality by delivering high energy stimulation through specific segmented electrodes that are positioned and activated to target only the intended nerve fibers, while surrounding tissues receive minimal or no stimulation due to the localized nature of the segmented electrode activation.
