Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate components are used to form different images, then image diversity is improved, but device complexity increases and installation space requirements increase

Engineering Contradiction:

Improveimage diversityVSAvoidnumber of parts

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The imaging unit is designed to perform multiple functions by forming different images (first image and second image) through a single integrated structure. The unit includes multiple light-emitting surfaces that can be selectively activated to create different illumination patterns on the ground, eliminating the need for separate imaging components for each image type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple imaging functions are merged into a single imaging unit. The unit combines multiple light-emitting surfaces, optical paths, and control mechanisms into one integrated component that can generate different images by controlling which light-emitting surfaces are activated and how light is directed through the unit.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If multiple separate components are used to form different images, then image diversity is improved, but installation space requirements increase

Engineering Contradiction:

Improveimage diversityVSAvoidinstallation space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The imaging unit employs a nested structure where multiple light-emitting surfaces and optical elements are arranged in a compact, space-efficient configuration. The unit integrates multiple functional elements within a single housing, with light paths and components arranged to minimize the overall footprint while maintaining the capability to form multiple distinct images.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If multiple light sources are used to form multiple images, then image diversity is improved, but component interference increases

Engineering Contradiction:

Improveimage diversityVSAvoidcomponent interference

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The imaging unit is segmented into distinct optical paths and light-emitting surfaces that are spatially separated and functionally independent. Each light-emitting surface corresponds to a specific image type, and the unit includes structures that prevent light from one path from interfering with another path, such as light shields or baffles positioned to block cross-contamination between optical channels.

Inventive Principle:

Principle #1Segmentation
