Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate couplers are used for each vehicle to optimize the angle of view, then the angle of view can be optimized for each vehicle, but the manufacturing cost increases
Solution Approach 1:
The patent applies universality by designing a single standardized coupler that can be used across different vehicle types. The coupler achieves multi-functionality through its elastic member mechanism that provides adjustable angle of view compensation without requiring vehicle-specific customization, thereby reducing manufacturing costs while maintaining adaptability.
Solution Approach 2:
The patent employs parameter changes by utilizing an elastic member whose deformation characteristics allow the coupler to adjust the camera's angle of view. The elastic member's flexibility parameter enables the system to compensate for different windshield angles and vehicle sizes without requiring different coupler designs, thus maintaining low manufacturing costs while achieving vehicle-specific optimization.
2Adaptability or versatility
If separate couplers are used for each vehicle, then the angle of view can be optimized, but the device complexity increases
Solution Approach 1:
The standardized coupler design with integrated elastic member provides a universal solution that reduces device complexity. Instead of requiring multiple different coupler configurations for different vehicles, a single coupler type handles all adjustments through the elastic member's inherent flexibility, simplifying the overall system architecture.
Solution Approach 2:
The elastic member provides self-service functionality by automatically adjusting to compensate for different windshield angles and vehicle configurations. The elastic deformation occurs passively without requiring complex control mechanisms, reducing the overall device complexity while maintaining the ability to optimize angle of view for each vehicle.
3Ease of manufacture
If a fixed camera mounting structure is used, then the manufacturing cost is reduced, but the angle of view changes due to manufacturing tolerances and external forces
Solution Approach 1:
The elastic member in the coupler provides beforehand cushioning by compensating for angle deviations before they affect the camera's field of view. The elastic deformation absorbs the effects of manufacturing tolerances and external forces, maintaining stable angle of view despite variations in mounting conditions, thus improving reliability without increasing manufacturing cost.
Solution Approach 2:
The elastic member's deformation parameter changes in response to external forces and manufacturing variations, allowing the coupler to dynamically adjust and maintain the camera's angle of view. This passive parameter adjustment provides stability against external forces while keeping the structure simple and cost-effective.
