Vehicle Aiming Lamp Rotation Center Decoupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reflector integrated aiming devices for vehicle lamps require additional structures like pivots and retainers, increasing the size and reducing collision performance due to the need for a large rear space, which complicates gap management and stability.
Innovation Solution
A rotation center decoupling type aiming lamp system where the aiming axis is positioned above or ahead of the aiming point reference line, using a reflector bracket and angular motion to adjust the light source's direction without conventional pivots or retainers, allowing for reduced internal space occupation and improved structural robustness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional structures like pivots and retainers are used for aiming axis rotation, then the aiming function is achieved, but the lamp size increases and collision performance deteriorates
Solution Approach 1:
The patent removes the conventional pivot and retainer structures from the aiming device. Instead of using these separate additional components, the invention integrates the rotation function directly into the aiming axis assembly, eliminating the need for extra structures that occupied rear space and increased lamp size.
Solution Approach 2:
The invention combines the rotation center formation with the aiming axis itself. The upper end of the aiming axis directly forms the rotation center, merging the functions of the aiming axis and rotation pivot into a single integrated structure, thereby eliminating the need for separate pivot and retainer components.
2Ease of operation
If additional structures like pivots and retainers are connected to the aiming axis, then the aiming adjustment is enabled, but the rear space requirement increases by about 57 mm
Solution Approach 1:
The patent extracts and removes the pivot and retainer structures that previously required significant rear space. By eliminating these separate components, the invention reduces the rear space requirement from about 57 mm to a much smaller dimension, allowing compact lamp design without compromising aiming adjustment functionality.
Solution Approach 2:
Instead of having the rotation center formed by separate pivot structures behind the reflector, the invention inverts the approach by having the upper end of the aiming axis itself form the rotation center. This reverses the conventional arrangement and eliminates the need for rear space accommodation of additional rotation mechanisms.
3Device complexity
If the aiming axis is positioned on the rear end of the reflector, then the aiming structure is simplified, but the front movement amount increases making gap management disadvantageous
Solution Approach 1:
The patent changes the spatial arrangement by positioning the rotation center at the upper end of the aiming axis rather than on the rear end of the reflector. This dimensional repositioning creates a more favorable geometry that reduces the front movement amount of the reflector during aiming adjustment, improving gap management while maintaining structural simplicity.
4Adaptability or versatility
If a large rear space is provided for the aiming device, then the aiming structure can accommodate additional components, but the collision performance of the vehicle deteriorates
Solution Approach 1:
The invention removes the additional pivot and retainer structures that required large rear space accommodation. By extracting these unnecessary components, the lamp achieves compact dimensions that improve vehicle collision performance while still providing adequate space for the essential aiming adjustment mechanism through the integrated rotation center design.

AI summary
A rotation center decoupling type aiming lamp applied to a vehicle includes an aiming device in which an aiming axis spaced apart from an aiming point reference line of an aiming point axis at a distance of an aiming adjustment height is operated as a rotation center of the reflector, and an aiming angle is changed through an aiming point axis to which the reflector is attached by a reflector bracket, such that the rotation center of the reflector adjusting a light radiation direction may be formed at a position above or ahead of the aiming point reference line, thereby reducing an occupation space of the aiming device and securing stability of the aiming driving, and particularly, a sufficient rear shock absorption space may also be secured in the aiming lamp, thereby securing structural robustness while satisfying low-speed collision regulations.
