Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If large imaging equipment with enclosed chamber is used to ensure proper lighting and timing for skin imaging, then measurement precision is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:

Improveskin imaging qualityVSAvoidequipment size

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The device is divided into separate functional modules: a wearable skin testing component and a separate imaging component. The imaging apparatus can be detached and operated independently, allowing the skin testing function to be performed on the wearable device while imaging is captured by the separate apparatus, thus reducing the complexity of any single component while maintaining overall functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A transmission line is introduced as an intermediary connection between the wearable device and the imaging apparatus. This allows the wearable device to perform skin testing without requiring the imaging equipment to be physically attached or integrated, enabling the imaging function to be performed remotely while maintaining measurement precision through the transmission connection.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If professional operators are required to operate testing equipment to ensure test conditions are met, then measurement precision is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvetest result accuracyVSAvoidself-administration capability

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The wearable device is designed with automatic timing functionality that begins when the skin testing component is attached to the wearable device. The system automatically manages the test duration and triggers imaging at the appropriate time without requiring professional operator intervention, allowing users to perform self-administered testing while maintaining precise test conditions.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The device pre-sets the test duration and imaging timing parameters before use. When the skin testing component is attached, the system automatically initiates the timing sequence and will trigger imaging at the predetermined time without requiring the user to manually control these parameters, thus simplifying operation while ensuring test accuracy.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If enclosed chamber with specialized lighting is used to meet imaging requirements, then measurement precision is improved, but loss of time increases

Engineering Contradiction:

Improveskin reaction imaging qualityVSAvoidtesting time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The imaging apparatus is designed to be detachable and portable, allowing it to be moved freely without requiring a fixed enclosed chamber setup. The lighting and imaging functions can be activated dynamically when needed, eliminating the need for time-consuming setup and teardown of enclosed chambers while maintaining the necessary lighting conditions for precise skin reaction imaging.

Inventive Principle:

Principle #15Dynamics
