Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing indicator lamps use a fixed illumination range, then the structure is simple and reliable, but the adaptability to different driving states is poor
Solution Approach 1:
The patent applies the dynamics principle by making the shielding assembly movable instead of fixed. The driving assembly drives the shielding assembly to move to different positions, dynamically adjusting the illumination pattern to match different driving states such as navigation, driving assistance, and head unit data display requirements.
Solution Approach 2:
The patent segments the illumination function by using a shielding assembly that can be positioned at different locations to create different light patterns. This allows the single light source to be divided into multiple functional zones, each serving different driving information display needs.
2Adaptability or versatility
If existing indicator lamps implement a single indication function, then the device complexity is low, but the versatility of information display is limited
Solution Approach 1:
The patent implements multi-functionality by enabling a single vehicle light module to display multiple types of information including navigation routes, driving assistance data, and head unit information. The shielding assembly's ability to assume different positions allows one device to perform multiple indication functions that would traditionally require separate lamps.
3Manufacturing precision
If the illumination range is fixed, then the manufacturing precision requirement is low, but the accuracy of indicating different driving states is insufficient
Solution Approach 1:
The patent employs feedback control where the control assembly receives driving state information and automatically adjusts the shielding assembly's position accordingly. This closed-loop control ensures accurate illumination patterns for different driving states without requiring manual intervention or complex mechanical positioning systems.
