Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lighting functions are packaged in a single light module, then the device integrates multiple functions, but it becomes difficult to meet different country-specific regulatory requirements for light color and type
Solution Approach 1:
The light module is divided into separate light sources (first light source, second light source, third light source) that can be independently controlled. Each light source can be selectively activated to provide different lighting functions (security light, running light, turn signal, etc.), allowing the system to meet different regulatory requirements by activating only the necessary light sources for each market.
Solution Approach 2:
Different portions of the light module have specialized optical components tailored to specific functions. The first light source has a reflector for security lighting, the second light source has a light collector for turn signals, and the third light source has optics for puddle lighting. This local specialization allows each region to emit the appropriate color and intensity for its regulatory requirements.
2Reliability
If light functions are customized for different countries, then regulatory compliance is achieved, but standardization across product lines becomes difficult
Solution Approach 1:
The light module is designed as a universal platform that can serve multiple markets and regulations. By incorporating multiple light sources with different optical characteristics within a single module, the same physical component can be deployed globally, with the control system activating only the required functions for each region. This maintains manufacturing standardization while achieving local regulatory compliance.
3Adaptability or versatility
If different light sources are used for different functions, then functional performance is optimized, but the number of components and system complexity increases
Solution Approach 1:
Multiple light sources with different optical characteristics are merged into a single integrated light module. The first light source with reflector, second light source with light collector, and third light source with optics are combined in one housing, allowing diverse lighting functions to be achieved without requiring separate light modules for each function. This reduces the overall quantity of components while maintaining functional diversity.
