Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If electromagnetic or ultrasound waves are applied across a range of frequencies to induce resonances in DNA molecules, then unique spectral responses for identification are obtained, but interference from anatomical structures reduces measurement precision

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies electromagnetic or ultrasound waves across a range of frequencies to induce resonances in DNA molecules. By exciting the DNA at its natural resonant frequencies, the system generates characteristic spectral responses that serve as unique biometric identifiers, resolving the contradiction by enhancing measurement precision through resonance-based detection despite anatomical interference.

Inventive Principle:

Solution Approach 2:

The patent detects changes in the spectral characteristics (analogous to color changes in optical spectroscopy) of biological tissues when exposed to electromagnetic or ultrasound waves. The unique spectral response patterns, which vary by individual, are identified by analyzing how different frequencies are absorbed or reflected, enabling precise differentiation despite background interference from anatomical structures.

Solution Approach 1:

The patent employs focusing techniques that concentrate electromagnetic or ultrasound waves onto the target tissue before resonance occurs. By pre-positioning and pre-focusing the energy delivery, the system maximizes the intensity of resonance signals returned to the receiver, thereby improving detection accuracy without requiring excessively complex high-sensitivity receivers.

Inventive Principle:

Solution Approach 2:

The patent replaces complex mechanical signal amplification systems with resonance-based detection. By tuning the frequency of applied waves to match the natural resonant frequencies of DNA, the system achieves signal amplification through the resonance phenomenon itself, reducing the need for complex electronic amplification and signal processing hardware.

Solution Approach 1:

The patent applies electromagnetic or ultrasound waves in periodic sweeps across a range of frequencies to efficiently map the spectral response. By systematically cycling through frequency bands and identifying resonant peaks, the system achieves precise spectral analysis in a time-efficient manner, resolving the contradiction between measurement precision and measurement duration.
