Solution Overview
Problem
Existing optical measuring devices for vehicles, particularly those integrated into the radiator grille, face challenges in minimizing installation space due to the large requirements of the receiving unit, which includes the receiving lens and deflection mirror, necessitating precise and complex adjustments.
Innovation Solution
An optical measuring device with a carrier that allows separate and precise adjustment of the receiving lens and deflection mirror using engagement elements and slot-like depressions, enabling precise positioning and minimization of installation space by optimizing the shape and placement of these components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the receiving unit (including receiving lens and deflecting mirror) is designed with traditional mounting structures, then the components can be assembled, but the installation space is large and requires complex adjustments to achieve precise positioning
Solution Approach 1:
The patent implements adjustable mounting structures with slot-like depressions that allow the receiving lens and deflecting mirror to be positioned dynamically during assembly. The engagement elements can slide within the slots to achieve precise positioning, transforming a static mounting problem into a dynamic adjustment process that reduces both space and complexity
Solution Approach 2:
The patent introduces engagement elements as intermediary components between the receiving lens/deflecting mirror and the carrier. These engagement elements with slot-like depressions act as mediators that simplify the adjustment process by providing guided movement paths, reducing the complexity of direct component-to-carrier alignment
2Device complexity
If the receiving lens and deflecting mirror are mounted on a common carrier without separate adjustment mechanisms, then the device structure is simpler, but precise positioning of each component becomes difficult
Solution Approach 1:
The patent segments the adjustment mechanism for the receiving lens and deflecting mirror into separate, independent systems. Each component has its own engagement elements and slot-like depressions on the carrier, allowing independent adjustment without interfering with the other component's positioning. This segmentation enables precise positioning while maintaining relatively simple overall structure
