Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lighting modules are combined in one lighting device to achieve multiple lighting functions, then the lighting versatility is improved, but the device complexity and assembly difficulty increase due to shape constraints imposed by vehicle body shapes
Solution Approach 1:
The patent combines multiple lighting modules (first lighting module with cutoff, second lighting module without cutoff) into a single lighting device housing. These modules share common structural elements including a plate, adjustment mechanism, and mounting features, thereby achieving multiple lighting functions (low beam, high beam, fog lights) while reducing overall device complexity compared to separate modular assemblies
Solution Approach 2:
The lighting device is designed with universal features that enable multiple lighting functions within a single device structure. The housing and mounting system accommodate different module types (with and without cutoff), and the shared adjustment mechanism allows unified positioning for various beam patterns, making the device adaptable to different vehicle body shapes and lighting requirements
2Adaptability or versatility
If the lighting device is designed to conform to particular body shapes with offset modules, then the adaptability to vehicle shapes is improved, but the bulk and assembly difficulty increase
Solution Approach 1:
The lighting device employs asymmetric design elements to accommodate different vehicle body shapes. The housing features asymmetric mounting surfaces and attachment points that allow the device to conform to various vehicle front-end geometries. The plate and modules can be positioned at different offsets while maintaining proper optical alignment through the shared adjustment mechanism
Solution Approach 2:
The patent introduces an inclined plate at a specific angle relative to the vehicle body, creating a new geometric dimension that simplifies the spatial arrangement of offset modules. This angular orientation allows modules positioned at different locations to project light beams that converge or parallel along the optical axis, reducing the complexity of three-dimensional positioning and assembly
3Reliability
If a thick lens is used in the light-emitting module to achieve the required focal length, then the optical performance is improved, but the weight and production complexity increase
Solution Approach 1:
The lighting device incorporates an adjustment mechanism that allows dynamic positioning of the plate and lighting modules along the optical axis. This dynamic adjustment capability enables the system to achieve proper focus and beam pattern without requiring a fixed thick lens design, allowing for lighter lens materials and simpler production while maintaining optical performance through positional optimization
