Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate optical components 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 component that performs multiple image-forming functions simultaneously. The optical lens unit is divided into multiple lens areas, each capable of forming different images with various attributes (shape, position, brightness, size, color). This multi-functional design eliminates the need for separate optical components for each image type, thereby reducing device complexity and part count while maintaining high image variety and adaptability.
Solution Approach 2:
The optical lens unit is segmented into multiple lens areas, where each lens area corresponds to specific light sources and can form independent images. This segmentation allows each region to be optimized for specific image-forming tasks while being part of a unified component structure. The divided lens areas enable flexible control over image attributes without requiring completely separate optical assemblies for each function.
2Adaptability or versatility
If multiple separate optical components are used to form different images, then image variety and functionality are improved, but manufacturing cost increases
Solution Approach 1:
By designing a single optical component that can form multiple types of images (static, dynamic, various shapes and positions) through its divided lens areas, the patent eliminates the need to manufacture and assemble multiple separate optical components. This universal design significantly reduces manufacturing complexity, assembly requirements, and overall production cost while maintaining the capability to generate diverse image patterns for enhanced vehicle communication.
3Reliability
If traditional illumination and signaling lamps are used, then basic functionality is maintained, but information communication capability is limited
Solution Approach 1:
The patent transforms traditional single-function illumination and signaling lamps into multi-functional units that can simultaneously perform basic lighting tasks and generate various image patterns for enhanced information communication. The optical lens unit with multiple lens areas enables the formation of different image types (static, dynamic, animated) that convey additional information to surrounding vehicles and pedestrians, thereby reducing information loss while maintaining reliable basic functions.
Solution Approach 2:
The patent introduces dynamic image formation capabilities alongside static illumination functions. The optical system can generate both steady images for basic signaling and dynamic/images that change over time for enhanced communication. This dynamic capability allows the lamp to convey more information states (animation effects, sequential patterns) without compromising the reliability of fundamental illumination and signaling operations.
