Vehicle Lamp Modular Aiming Unit Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamp designs for vehicles using multiple optical modules require a large number of parts and complex manufacturing processes due to the need for individual aiming of optical modules, which increases complexity and cost.
Innovation Solution
A lamp design featuring a modular aiming unit with adjustable heat dissipation units, mounting units, reflective units, and angle adjustment mechanisms, allowing for independent height and horizontal angle adjustments of optical systems, reducing the number of required parts and manufacturing steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional aiming method with multiple ball joints and screws is used for each optical module, then individual aiming of optical modules is achieved, but the number of parts and manufacturing processes increases
Solution Approach 1:
The patent combines multiple aiming functions (vertical adjustment, horizontal adjustment, and fixation) into a single integrated aiming unit. Each optical module shares one common aiming unit that provides both vertical and horizontal positioning capabilities, eliminating the need for separate ball joints and multiple screws for each module. This merging approach maintains individual aiming precision while significantly reducing the total number of parts.
Solution Approach 2:
The aiming unit is designed as a universal component that can be used for all optical modules in the lamp. The single aiming unit performs multiple functions including vertical positioning, horizontal positioning, and secure fixation for any optical module. This multi-functional design allows one aiming unit to replace what would traditionally require multiple separate components for each individual module.

Solution Approach 2:
The aiming unit is pre-assembled as a complete functional module before installation. The vertical adjustment mechanism, horizontal adjustment mechanism, and fixation elements are all integrated into the aiming unit in advance. This preliminary assembly simplifies the manufacturing process by reducing the number of separate assembly steps required during final lamp assembly, as the aiming unit can be installed as a single component.
