Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate optical units are used to form different images, then image variety and functionality are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent implements a single optical unit that can form multiple different images by controlling light emission from multiple light sources (first, second, third light sources) through a shared optical lens unit. This multi-functional approach allows the same optical components to generate various images (first image, second image, third image) with different attributes such as shape, size, brightness, and color, thereby reducing the number of parts while maintaining image variety.
Solution Approach 2:
The patent combines multiple light sources and their corresponding optical paths into a single integrated optical lens unit. The optical lens unit receives light from multiple light sources and forms multiple images simultaneously or sequentially, merging what would traditionally require separate optical units. This integration reduces device complexity and manufacturing cost while preserving the capability to generate diverse images.

3Ease of manufacture
If static images are formed using traditional lamp structures, then manufacturing simplicity is maintained, but dynamic image formation capability is limited
Solution Approach 1:
The patent enables dynamic image formation by controlling the emission timing, intensity, and combination of multiple light sources (first, second, third light sources) within a single optical lens unit. This allows the system to transition from static images to dynamic images and animation effects by varying which light sources are active and their emission characteristics, while maintaining the manufacturing simplicity of a single integrated optical unit.
Solution Approach 2:
The patent achieves dynamic image formation by changing parameters such as light emission timing, intensity, and color of multiple light sources. By controlling which light sources are active and their emission characteristics, the system can generate various images with different attributes (shape, size, brightness, color) and create animation effects, all while using a single optical lens unit that maintains manufacturing simplicity.
