Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical signals are applied to stimulate acupuncture points or treat pain, then treatment efficacy is improved, but the varying electrical impedance of different patients causes inconsistent treatment outcomes
Solution Approach 1:
The apparatus measures the electrical impedance of the patient's tissue and uses this information to automatically adjust the electrical signal parameters (amplitude, frequency, pulse width) to optimize stimulation effectiveness for each individual patient, ensuring consistent treatment outcomes despite biological variations
Solution Approach 2:
The system dynamically changes electrical signal parameters based on measured tissue impedance characteristics, adapting voltage, current, frequency, and pulse duration to match each patient's specific electrical properties, thereby resolving the contradiction between reliable treatment and individual adaptability
2Reliability
If personalized electrical signal waveforms and intensities are used to treat different patients, then treatment effectiveness is improved, but the complexity of selecting and adjusting parameters increases
Solution Approach 1:
The apparatus performs self-adjustment by automatically measuring tissue impedance and selecting optimal electrical signal parameters without requiring the operator to manually tune multiple parameters, thereby maintaining treatment effectiveness while eliminating parameter selection complexity
Solution Approach 2:
The system uses a standardized measurement protocol that rapidly determines tissue electrical characteristics and automatically computes optimal stimulation parameters, accelerating the parameter selection process and eliminating the need for complex manual adjustments
3Measurement precision
If invasive measurements are used to assess biological tissue conditions, then measurement precision is improved, but the ease of operation and patient comfort deteriorate
Solution Approach 1:
The apparatus uses surface electrodes as intermediaries to non-invasively measure tissue electrical impedance, which provides sufficient information about tissue conditions without requiring needle insertion or other invasive procedures, thereby maintaining measurement precision while improving ease of operation and patient comfort

AI summary
An apparatus (1) for electrostimulation of biological tissues is proposed. The apparatus (1) comprises a signal generator (53) adapted to generate an electrical signal, an electrode (40) electrically connected to the signal generator (53) to receive the electrical signal generated by the signal generator (53), and a control unit (51) operatively connected to the signal generator (53) to adjust parameters of the generated electrical signal and to read the parameters of an electrical signal returning from the electrode (40). Advantageously, the control unit (51) is configured for determining (1001) the parameters of an electrical signal (stx), reading (1005) the electrical signal (sr) returning from the electrode (40), comparing (1009) at least one parameter of the return electrical signal (sr) with a corresponding parameter of an expected return signal, and if one or more of the parameters of the return electrical signal (sr) differ from the corresponding parameters of the expected return signal beyond a threshold value, then the control unit (51) is configured for modifying (1013) the parameters of the electrical signal (stx) and repeating steps b) to d).
