Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional 3D scanning device uses rotation to scan objects, then scanning coverage is improved, but optical alignment variation occurs leading to measurement errors

Engineering Contradiction:

Improvescanning coverageVSAvoidmeasurement accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent divides the scanning function into multiple fixed micro-optical elements (first, second, and third micro-optical elements) with different inclination patterns. Each element handles a specific angular range, eliminating the need for rotation while maintaining comprehensive scanning coverage through spatial segmentation of optical functions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from temporal scanning (rotation over time) to spatial scanning (multiple fixed elements at different positions and angles). By arranging micro-optical elements with different inclination angles in space, the system achieves wide scanning coverage without mechanical rotation, thereby maintaining measurement precision.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If a conventional 3D scanning device uses rotation for scanning, then scanning functionality is achieved, but durability issues occur due to mechanical rotation

Engineering Contradiction:

Improvescanning functionalityVSAvoiddurability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent replaces the mechanical rotation system with a static optical system consisting of multiple micro-optical elements with different inclination patterns. This substitution eliminates mechanical wear and rotational failures while maintaining scanning functionality through fixed optical paths with varying angles.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent achieves dynamic scanning coverage equivalent to rotation by using multiple static optical elements with different inclination angles. The system dynamically switches between different optical paths through the arrangement of fixed elements rather than through mechanical movement, improving reliability.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If a conventional 3D scanning device uses rotation mechanism, then scanning is enabled, but structure becomes complicated leading to high manufacturing cost

Engineering Contradiction:

Improvescanning capabilityVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the complex mechanical rotation mechanism from the system. Instead, it uses a simplified arrangement of multiple micro-optical elements with different inclination patterns, reducing structural complexity while maintaining scanning capability through fixed optical components.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent achieves multi-functional scanning capability using multiple micro-optical elements that each serve a specific angular range. This universal approach replaces the need for a single complex rotating mechanism with several simpler fixed elements, each optimized for a particular scanning sector.

Inventive Principle:

Principle #6Universality (Multi-functionality)
