Vehicle Headlamp Guide Bracket for Tilt Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle headlamp adjustment mechanisms are difficult and time-consuming to access and adjust, especially after assembly or during servicing, due to their location within the engine compartment, making it hard to achieve the desired photometric distribution and requiring manual, labor-intensive adjustments.
Innovation Solution
An adjustable lighting device with a guide bracket extending from the headlamp body to provide accessible inlet openings for a hexagonal male tool, allowing easy rotation of the rotating element to adjust the tilt angle of the light beam, both manually and automatically, even when the device is mounted on a vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the control device is positioned inside the engine compartment for compact installation, then the device complexity is reduced, but the ease of operation deteriorates due to difficult accessibility
Solution Approach 1:
The patent introduces a guide bracket that extends upward from the headlamp body to the vicinity of the upper edge of the engine compartment, creating a new spatial dimension for tool access. This vertical extension allows the adjustment tool to reach the rotating element from above, transforming the access path from a difficult lateral approach within the engine compartment to a straightforward vertical approach, thereby resolving the contradiction between compact installation and easy adjustment.
2Manufacturing precision
If the rotating element is positioned deep within the engine compartment, then the manufacturing precision is improved for proper alignment, but the loss of time increases during manual adjustment
Solution Approach 1:
The guide bracket serves as an intermediary structure that bridges the gap between the easily accessible upper engine compartment area and the precisely positioned rotating element deep within the headlamp assembly. This intermediary component transmits the adjustment torque from the tool to the rotating element while maintaining proper alignment, thus achieving both manufacturing precision and reduced adjustment time.
3Device complexity
If the control device requires manual adjustment through difficult access, then the device complexity remains simple, but the productivity decreases due to time-consuming adjustments
Solution Approach 1:
The patent segments the adjustment system into two distinct parts: the control device remaining simple and compact within the headlamp body, and the guide bracket extending outward to provide tool access. This segmentation allows the control mechanism to remain simple while the guide bracket handles the accessibility function, thereby improving productivity without increasing the complexity of the core control mechanism.

AI summary
Adjustable lighting device (1) including a housing or headlamp body (2) at least partially housed inside an engine compartment (3) of a vehicle, a rotating element (8) carried by a seat (9) of the housing to adjust the tilt angle of a light beam (6) emitted by the lighting element and a guide bracket (14) for a male tool (11) for driving in rotation the rotating element; the bracket extends from the seat (9) as far as an upper portion (15) of the housing and has an upper end (16) provided with a first inlet opening (18) easy to access in use, a base (20) provided with a second inlet opening (19) and a guide channel (21) arranged laterally to the second inlet opening (19) starting from the first inlet opening (18) up to the base (20), intersected at least partially by the second inlet opening (19), so that the rotating element (8) is accessible for the male tool both through the guide channel (21) and through the second inlet opening (19).
