Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If non-invasive electrodes are placed on pre-determined stimulation points, then patient safety is improved by avoiding needle insertion, but treatment efficacy deteriorates due to imprecise nerve targeting
Solution Approach 1:
The system measures resistance and current-voltage characteristics between each electrode and reference electrode, using this feedback to automatically identify and select the electrode with optimal neural contact. This feedback mechanism enables non-invasive electrodes to achieve precise nerve targeting without requiring manual placement expertise or invasive procedures.
Solution Approach 2:
The system performs automatic electrode selection and pulse parameter adjustment without requiring continuous manual intervention. The control unit autonomously evaluates electrode characteristics, selects the optimal electrode, and adapts pulse parameters based on real-time measurements, enabling the system to self-optimize treatment delivery.
2Device complexity
If fixed intensity settings are used in non-invasive neuromodulation, then device complexity is reduced, but treatment efficacy deteriorates due to inability to optimize for individual patient anatomy
Solution Approach 1:
The system dynamically adjusts pulse intensity and waveform parameters based on real-time resistance and current-voltage measurements. Rather than using fixed factory presets, the pulse generator adapts its output parameters to match the specific electrical characteristics of each patient's tissue and nerve, enabling personalized optimization without excessive complexity.
Solution Approach 2:
The system changes multiple pulse parameters including intensity, duration, and waveform shape based on measured electrical characteristics. The control unit modifies these parameters automatically according to the resistance and current-voltage characteristics of each electrode-nerve interface, allowing precise tailoring of neuromodulation to individual patient anatomy.
3Adaptability or versatility
If manual electrode placement is performed, then adaptability to individual patient anatomy is improved, but treatment reliability deteriorates due to risk of incorrect placement and nerve damage
Solution Approach 1:
The system continuously monitors resistance and current-voltage characteristics to verify proper electrode-nerve contact. This real-time feedback enables the system to detect suboptimal placement and either alert the operator or automatically adjust electrode selection, thereby maintaining adaptability while significantly improving reliability by preventing incorrect placement and potential nerve damage.
Solution Approach 2:
The system replaces manual mechanical placement with automated electrical measurement and selection. Instead of relying on operator skill to physically position electrodes, the system uses electrical property measurements to objectively identify the optimal electrode, substituting mechanical placement with an automated sensing and selection process that improves both adaptability and reliability.
4Measurement precision
If electrodes are placed in immediate vicinity of nerve using needle electrodes, then treatment efficacy is improved through precise nerve targeting, but patient safety deteriorates due to risk of nerve damage from insertion
Solution Approach 1:
The system uses electrical resistance and current-voltage measurements—properties that would be harmful indicators of potential nerve damage—to instead identify optimal treatment sites. By measuring these electrical characteristics non-invasively, the system converts what would be dangerous indicators into beneficial guidance signals for precise electrode placement, achieving accurate nerve targeting without the harm of needle insertion.
Solution Approach 2:
The system introduces electrical resistance and current-voltage measurements as intermediary indicators between the electrode and the nerve. Rather than directly inserting electrodes near the nerve, the system uses these electrical measurements as mediators to indirectly identify and target the nerve location, eliminating the need for direct mechanical proximity and associated damage risks.
