Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lighting system uses multiple separate lighting devices to form pattern images at different locations, then the ability to convey information at various locations is improved, but the structural complexity increases
Solution Approach 1:
The patent implements a single lighting device that can form pattern images at multiple different locations on the road surface by adjusting the light emission direction. This universal device replaces what would traditionally require multiple separate lighting devices, thereby reducing structural complexity while maintaining the versatility to convey information at various locations around the vehicle
Solution Approach 2:
The lighting device incorporates dynamic control capabilities that allow it to adjust the light emission direction and target different locations on the road surface in real-time. This dynamic adjustment mechanism enables one static physical device to perform the function of multiple devices positioned at different locations, resolving the contradiction between versatility and structural complexity
2Area of stationary object
If pattern images are formed at different distances from the lighting device, then the coverage area is improved, but the uniformity of pattern image size and brightness deteriorates
Solution Approach 1:
The control device dynamically adjusts light emission parameters including intensity and direction angles based on the target distance. When forming pattern images at greater distances, the system increases light intensity and adjusts emission angles to compensate for distance-related attenuation and spreading, thereby maintaining uniform pattern image size and brightness across different coverage areas
Solution Approach 2:
The system incorporates detection units that detect vehicle state information and surrounding environment information, which are fed back to the control device. The control device uses this feedback to calculate appropriate light emission parameters that ensure uniform pattern image characteristics at various distances,实现ing adaptive compensation for distance-related variations
