Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lens arrangement with linearly arranged lens elements is used to create a three-dimensional lighting effect, then a spatial appearance with depth effect is improved, but the installation depth cannot be minimized and the spatial appearance is limited
Solution Approach 1:
The patent transitions from a linear one-dimensional arrangement of lens elements to a two-dimensional matrix-like arrangement. This dimensional change allows the light sources to be distributed across a planar surface rather than along a line, creating a more compact installation depth while maintaining the three-dimensional lighting effect through the coordinated illumination of multiple film segments.
Solution Approach 2:
The patent divides the lighting system into discrete segments: multiple light sources, multiple film segments with graphic elements, and multiple lens elements arranged in a matrix. Each light source illuminates specific film segments through corresponding lens elements, allowing independent control and compact arrangement while generating complex three-dimensional lighting functions.
2Illumination intensity
If a hologram arrangement is used to generate a holographic luminous graphic with depth effect, then the spatial appearance is improved, but the installation space cannot be minimized
Solution Approach 1:
Instead of using a complex hologram arrangement that requires significant installation space, the patent uses flat film material with graphic elements that are exposed and attached to the lens arrangement. This creates a simplified copy or representation of the desired luminous graphic that achieves the same visual effect with minimal installation space and depth.
Solution Approach 2:
The patent replaces the bulky hologram arrangement with thin flat film material that carries the graphic elements. This thin film can be easily attached to the lens arrangement and illuminated by the light sources, achieving the desired holographic-like effect while minimizing installation volume and space requirements.
3Illumination intensity
If the lens elements are arranged linearly to produce a light pattern with depth effect, then the spatial appearance is improved, but the adaptability for different lighting functions is limited
Solution Approach 1:
The patent creates a universal lighting system where the matrix arrangement of light sources, film segments, and lens elements can generate multiple different lighting functions. By controlling which light sources are activated and how the film segments are arranged, the system can produce various lighting patterns including turn signals, taillights, brake lights, and other vehicle lighting functions, all with three-dimensional depth effect.
Solution Approach 2:
The patent enables dynamic control of the lighting system by independently controlling multiple light sources and their corresponding film segments. This allows the lighting device to dynamically switch between different lighting functions and patterns, providing high adaptability for various vehicle signaling requirements while maintaining the spatial depth effect through the matrix arrangement.
