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 color regulations for different light functions
Solution Approach 1:
The patent applies color changes by using a light collector with adjustable tinting properties. The light collector can modify the color of light emitted from a single light source to meet different regulatory requirements for various lighting functions (e.g., turn signals, running lights, brake lights). This allows one light source to produce multiple color outputs compliant with different country regulations.
Solution Approach 2:
The patent implements parameter changes by making the light collector's thickness and tinting adjustable. By changing the physical parameters of the light collector (thickness, tint concentration), the system can adapt the light output color to meet different regulatory standards across countries, enabling a single light module to serve multiple regulatory markets.
2Device complexity
If a single light source is used for multiple functions, then the device complexity is reduced, but the ability to meet diverse international color regulations deteriorates
Solution Approach 1:
The patent introduces a light collector as an intermediary component between the light source and the external environment. This intermediary element can selectively filter and modify the light from a single source to produce different colors required by various regulations, thus maintaining simple light source configuration while achieving regulatory compliance versatility.
3Reliability
If light functions are customized for different countries, then regulation compliance is improved, but the device cannot be standardized across product lines
Solution Approach 1:
The patent achieves universality by designing a light assembly with a single light source and an adjustable light collector that can serve multiple lighting functions (turn signal, running light, brake light, spotlight) while complying with different country regulations. This universal design allows the same basic assembly to be standardized across product lines and markets.
