Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If skin condition estimation is based on surface images captured by camera, then the method is simple to implement, but the accuracy of estimation is limited and the number of samples is restricted

Engineering Contradiction:

Improveskin condition estimation accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces core temperature as an intermediary parameter to bridge the gap between internal skin conditions and surface appearance. Instead of directly analyzing surface images, the system uses core temperature data (from wearables or manual measurement) as a mediator that reflects underlying skin health status, thereby improving estimation accuracy without requiring complex image processing systems

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/optical system of camera-based image capture with a thermal measurement approach. By substituting visual inspection with core temperature measurement (via wearables or thermometers), the system achieves more accurate skin condition estimation while simplifying the overall device requirements

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If skin condition estimation relies on surface image analysis, then the approach is straightforward, but it fails to account for underlying skin conditions and limits sample diversity

Engineering Contradiction:

Improveskin condition estimation reliabilityVSAvoidunderlying skin condition information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent adds a new dimension of measurement by incorporating core temperature data, which reflects internal physiological states. This dimensional expansion moves the estimation from purely surface-level analysis to a multi-level approach that includes deep tissue and internal body temperature information, thereby capturing underlying skin conditions that surface images cannot detect

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent makes the estimation system universal by accepting multiple data input types (core temperature from wearables, manual temperature measurement, and surface images). This multi-functional approach allows the system to work with diverse data sources and sample types, improving reliability while reducing information loss through flexible data acquisition methods

Inventive Principle:

Principle #6Universality (Multi-functionality)
