Vehicle Headlamp Leveling Spindle Layout for Compact Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle headlamp designs require a large installation space due to the spacing of the setting spindle and adjusting element, which limits the compactness of the illuminating apparatus.
Innovation Solution
The setting spindle and adjusting element are connected in a way that the movement of the adjusting element in the displacement direction causes a corresponding movement of the setting spindle, allowing them to be aligned in sections, thereby reducing the transverse spacing and saving installation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the setting spindle and adjusting element are spaced a distance apart in the transverse direction, then the components can operate independently without interference, but a large installation space is required
Solution Approach 1:
The patent merges the setting spindle and adjusting element by connecting them directly, eliminating the transverse spacing required in conventional designs. The adjusting element is connected to the setting spindle such that their movement paths overlap or align, allowing the components to occupy the same transverse space while maintaining functional independence through controlled movement sequences.
Solution Approach 2:
The patent resolves the spatial conflict by transitioning from transverse spacing to longitudinal sequencing. The adjusting element moves in the displacement direction (one dimension) while the setting spindle rotates around its longitudinal axis (another dimension), allowing both components to operate in the same transverse space by utilizing different movement dimensions and timing.
2Volume of moving object
If the setting spindle and adjusting element are connected directly, then installation space is reduced, but the complexity of coordinating their movements increases
Solution Approach 1:
The setting spindle serves multiple functions: it rotates to pivot the supporting frame horizontally and also translates axially to accommodate the movement of the adjusting element. This multi-functionality reduces the need for separate mechanisms and simplifies the overall coordination required, as one component handles both rotational and translational tasks.
Solution Approach 2:
The patent introduces a connecting structure that acts as an intermediary between the adjusting element and the setting spindle. This intermediary mechanism translates the linear displacement of the adjusting element into axial movement of the setting spindle, while allowing the setting spindle to independently rotate. This mediation simplifies the coordination by providing a mechanical coupling that automatically handles the movement relationship.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for a more compact design of the illuminating apparatus while still enabling the necessary movements for pivoting the supporting frame, thus maintaining the functionality of the headlamp.
Implementation Method 1
The setting spindle (5) has a male thread (7), and the transfer part (6) has a female thread (8), which is in engagement with the male thread of the setting spindle. The rotational movement of the setting spindle is transferred thereby to a pivoting of the transfer part and the supporting frame around the horizontal axis
Implementation Method 2
The adjusting element (4) can have a connecting region (12) for connection to the setting spindle (5), in particular the connecting region being designed as a ball head, at least in sections. The setting spindle (5) may furthermore have a receptacle (13) for the connecting region of the adjusting element, in particular the receptacle being designed as a socket corresponding to the ball head, at least in sections

AI summary
An illuminating apparatus for a vehicle, in particular a headlamp for a vehicle, comprises a housing, at least one light module for generating a light function, a supporting frame, which is pivotably arranged in the housing. The light module is mounted on the supporting frame such that it is pivoted along with the pivoting of the supporting frame. A manually actuatable adjuster pivots the supporting frame around a horizontal axis. The adjuster has a setting spindle, which is rotatable around its longitudinal axis and is used to pivot the supporting frame, a servomotor including an adjusting element, which is linearly displaceable in a displacement direction for the purpose of implementing an automatic headlamp leveling control. The setting spindle and the adjusting element being connected to each other in such a way that a movement of the adjusting element in the displacement direction effectuates a movement of the setting spindle.
