Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple wavelengths are used for imaging, then diagnostic accuracy is improved, but data volume increases and examination time is prolonged

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidexamination time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system dynamically changes the wavelength parameter of the light source based on the detected dental condition. The processor selects specific wavelengths from available options (e.g., 450nm for caries, 530nm for gum inflammation, 630nm for plaque) and configures the imaging system accordingly, avoiding the need to capture images at all wavelengths simultaneously.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system performs preliminary detection to identify the dental-related problem before conducting the main imaging. The processor first receives data about the dental condition and pre-configures the optimal wavelength settings, so that when imaging is performed, the system is already optimized for the specific condition, reducing overall examination time.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If multiple wavelengths are used for imaging, then diagnostic accuracy is improved, but data volume increases

Engineering Contradiction:
Improvediagnostic accuracyVSAvoiddata volume
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The system changes the wavelength parameter based on the specific dental condition detected, capturing images only at the most relevant wavelengths. This selective approach reduces the total number of images and data points collected while maintaining diagnostic accuracy for the identified condition.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system extracts and focuses on only the necessary wavelength information required for diagnosing the specific dental condition. By taking out only the relevant wavelength data (e.g., only 450nm for caries detection) and discarding unnecessary wavelengths, the system reduces data volume while preserving diagnostic capability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Illumination intensity

If continuous blue or UV light is used for illumination, then imaging capability is improved, but safety risks increase

Engineering Contradiction:
Improveimaging capabilityVSAvoidsafety risks
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

Instead of continuous illumination, the system uses periodic or pulsed light delivery at specific wavelengths only when needed for detection. The processor controls the light source to emit at particular wavelengths (including safer visible ranges) in controlled pulses rather than continuous exposure, reducing cumulative light damage to dental tissues.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system changes the wavelength parameter to select safer illumination options when appropriate. By offering multiple wavelength choices including visible light ranges (530nm, 630nm) in addition to blue/UV, the system can switch to safer wavelengths for conditions where they are sufficient, reducing exposure to potentially harmful high-energy light while maintaining imaging capability.

Inventive Principle:
Principle #35Parameter changes
