Vehicle Lighting Device with Rotating Arms for Compact Headlight Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle lighting devices require significant space and are excessively large due to the need for large swing angles and space for dimming, especially when multiple lighting modules are used, leading to inefficient internal space utilization.
Innovation Solution
A vehicle lighting device with rotating arms and modules that can independently rotate around horizontal shafts, utilizing a driving mechanism with slotted holes and connecting rods for precise adjustment, allowing for compact design and efficient dimming without the need for extensive rotation mechanisms on each module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple lighting modules are arranged in a conventional fixed bracket and the bracket rotates for dimming, then the lighting modules can be positioned and adjusted, but a large swing space is required inside the headlight, causing waste of internal space and excessively large headlight size
Solution Approach 1:
The patent divides the lighting assembly into multiple independently rotatable lighting modules (first lighting module, second lighting module, third lighting module) mounted on separate rotating mechanisms. Each module can rotate independently around its own rotation axis, allowing precise positioning without requiring the entire bracket to swing through large angles, thus reducing the overall space required for dimming operations.
Solution Approach 2:
The patent implements dynamic adjustment mechanisms where each lighting module is equipped with a rotating mechanism that can independently change the orientation of individual modules. This dynamic capability allows the lighting system to achieve various beam patterns by rotating modules to different angles, replacing the static bracket rotation approach and reducing the space needed for dimming.
2Ease of operation
If multiple lighting modules are arranged in a rotatable frame for independent rotation, then dimming can be achieved, but the adjacent lighting modules must be arranged at large intervals due to frame arrangement and rotation space requirements, still causing waste of internal space
Solution Approach 1:
The patent segments the rotation mechanism into three separate rotating mechanisms (first, second, and third rotating mechanisms), each handling one lighting module. This segmentation allows each module to rotate independently without requiring large clearance intervals between modules, as each has its own dedicated rotation axis and mechanism, optimizing the use of internal headlight space.
Solution Approach 2:
The patent utilizes vertical stacking arrangement where lighting modules are positioned at different heights (first module at highest position, second in middle, third at lowest) and rotate around horizontal axes. This three-dimensional arrangement allows independent rotation without requiring large horizontal intervals between modules, effectively utilizing vertical space to reduce overall footprint.
