Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If multiple illuminating devices are used to achieve wide-angle photography in dark environments, then the illumination coverage is improved, but the hardware cost increases and assembly procedures become complex

Engineering Contradiction:

Improveillumination coverageVSAvoidassembly procedures

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

The patent combines multiple light emitting modules (first light emitting module in central region, second light emitting modules in lateral regions) into a single integrated illumination device with a unified base. This merging approach achieves wide-angle illumination coverage while reducing the number of separate devices needed, thereby simplifying assembly procedures and reducing hardware cost.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The illumination device is segmented into functional regions (central region with first light emitting module, lateral regions with second light emitting modules) and light guiding modules (first light guiding module, second light guiding modules, third light guiding module). This segmentation allows each module to be optimized for its specific function while maintaining overall integration, resolving the contradiction between coverage and complexity.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple illuminating devices are arranged around camera lenses, then the wide-angle photography capability is improved, but the hardware cost increases

Engineering Contradiction:

Improvewide-angle photography capabilityVSAvoidhardware cost

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The single illumination device performs multiple functions: the first light emitting module provides central illumination, the second light emitting modules provide lateral illumination, and the third light guiding module ensures uniform distribution. This multi-functional design replaces multiple separate illuminating devices, reducing hardware cost while maintaining wide-angle photography capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If light guiding modules with different irradiation ranges are used, then the uniformity of illumination is improved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

Different light guiding modules are designed with specific local functions: the first light guiding module guides light from the central region, the second light guiding modules guide light from lateral regions, and the third light guiding module covers both central and lateral regions to ensure uniform distribution. This local quality optimization achieves uniform illumination without requiring complex overall design.

Inventive Principle:

Principle #3Local quality
