Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional adjustment devices are used for motor vehicle headlights, then the adjustment function is achieved, but the installation space required is excessive
Solution Approach 1:
The patent merges multiple adjustment functions (vertical and horizontal pivoting of multiple support frames) into a single integrated adjustment device. The coupling elements connect multiple support frames to a common mounting component, allowing simultaneous adjustment of multiple optically relevant components through shared actuating arms, thereby reducing the overall installation space while maintaining comprehensive adjustment capability.
Solution Approach 2:
The adjustment device is designed with universal coupling elements that can simultaneously pivot multiple support frames about both horizontal and vertical axes. The mounting component serves multiple functions by providing pivot points for several support frames and serving as the base for both vertical and horizontal adjustment mechanisms, reducing the need for separate adjustment devices for each component.
2Manufacturing precision
If multiple optically relevant components are adjusted independently, then each component can be precisely positioned, but the adjustment device becomes overly complex
Solution Approach 1:
The patent combines independent adjustment capabilities into a unified mechanism where coupling elements connect multiple support frames to a common mounting component. Each support frame can be independently positioned, but the coupling elements allow coordinated adjustment through shared actuating arms, maintaining precision while reducing mechanical complexity compared to fully independent adjustment systems.
Solution Approach 2:
The coupling elements act as intermediaries between the actuating arms and the support frames. These coupling elements translate the linear movement of actuating arms into rotational pivoting of support frames about horizontal and vertical axes, providing precise control while simplifying the direct connection between actuators and multiple optical components.
3Area of stationary object
If adjustment device is designed for compact installation, then space requirements are reduced, but flexibility in design is limited
Solution Approach 1:
The adjustment device employs dynamic pivot points and coupling elements that allow multiple support frames to be adjusted in various directions (vertical and horizontal pivoting). The actuating arms can move linearly to pivot support frames about different axes, providing design flexibility and adaptability within a compact structure that can accommodate different optical component configurations.
Solution Approach 2:
The patent introduces multiple dimensions of adjustment by enabling support frames to pivot about both horizontal and vertical axes. This multi-dimensional adjustment capability is achieved through coupling elements that connect to mounting components at different locations, allowing compact design while maintaining high design flexibility for various optical component arrangements.
