Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional lighting is used, then regulatory compliance is maintained, but brand identity expression and visibility are limited
Solution Approach 1:
The lighting system is divided into separate functional modules: grille lighting for brand identity expression and projection units for road surface display. This segmentation allows each module to operate independently within regulatory limits while collectively achieving enhanced branding capabilities.
Solution Approach 2:
The invention transitions from traditional two-dimensional lighting displays to three-dimensional optical images that can be projected onto the road surface. This dimensional expansion enables richer brand identity expression while maintaining compliance through controlled projection parameters.
2Illumination intensity
If road-surface projection lighting is used to expand visibility, then brand identity is enhanced, but regulatory restrictions and versatility issues arise
Solution Approach 1:
The projection system incorporates dynamic control capabilities that adjust projection intensity, duration, and patterns based on driving conditions, ambient light levels, and regulatory requirements. This dynamic adaptation ensures optimal visibility while maintaining compliance with varying regulatory standards.
Solution Approach 2:
The system modifies projection parameters such as luminance, projection area, and temporal patterns to balance visibility enhancement with regulatory compliance. By dynamically adjusting these parameters, the system achieves improved brand identity expression without violating lighting regulations.
3Adaptability or versatility
If grille lighting with three-dimensional optical image display is implemented, then brand identity and design possibilities are expanded, but device complexity increases
Solution Approach 1:
The grille lighting assembly is designed to perform multiple functions: displaying three-dimensional optical images for brand identity, providing aesthetic illumination, and serving as a structural element of the vehicle grille. This multi-functionality reduces the need for separate components, thereby managing complexity while expanding design possibilities.
Solution Approach 2:
The invention merges the grille structure with lighting elements, integrating the housing, lens, light source, and three-dimensional plate into a unified assembly. This consolidation simplifies installation and maintenance while enabling complex three-dimensional optical displays through the coordinated interaction of integrated components.
