Vehicle Headlight Adjusting Arm for Synchronized Module Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headlight systems with multiple adjustable components often experience misalignment due to the use of mechanical links and rods, which can result in incorrect illumination patterns and potential non-compliance with legal limits.
Innovation Solution
A vehicle headlight system comprising two illumination modules connected through a support structure and an adjusting arm that directly transfers movement from an actuator to both modules, maintaining their relative position and alignment during adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical links and rods are used to connect multiple adjustable components, then the components can be adjusted synchronously, but misalignment occurs between the components due to different rotational axes
Solution Approach 1:
The patent merges the adjustment function for multiple modules into a single adjusting arm that directly connects to the actuator. This combining of adjustment functions eliminates the intermediate mechanical links and rods that caused misalignment, allowing all modules to be adjusted synchronously while maintaining precise alignment through the unified adjusting arm structure.
Solution Approach 2:
The patent extracts and removes the intermediate mechanical links and rods from the adjustment mechanism. By eliminating these intermediate components that caused misalignment due to different rotational axes, the system achieves both synchronous adjustment and precise alignment directly through the adjusting arm connected to the actuator.
2Reliability
If multiple mechanical links and rods are used to connect adjustable components, then synchronous adjustment is achieved, but the number of parts increases making the system heavier and more complex
Solution Approach 1:
The patent combines multiple adjustment functions into a single adjusting arm that serves all modules. This merging eliminates the need for separate mechanical links and rods for each module connection, reducing the total number of parts while maintaining synchronous adjustment capability across all modules.
Solution Approach 2:
The adjusting arm is designed as a universal component that performs the adjustment function for multiple modules simultaneously. This multi-functional design allows a single component to replace what would traditionally require multiple separate links and rods, reducing system complexity and part count while maintaining full synchronous adjustment capability.
3Ease of operation
If mechanical links and rods are used to transfer movement between modules, then adjustment is achieved, but heat and vibrations affect different modules differently causing adjustment differences
Solution Approach 1:
The patent removes the intermediate mechanical links and rods that acted as heat and vibration transmission pathways. By eliminating these intermediate components, each module is directly connected to the adjusting arm and actuator, ensuring that heat and vibrations affect all modules equally rather than being differentially transmitted through multiple connection points.
Solution Approach 2:
The patent merges the connection structure so that all modules connect directly to the same adjusting arm from the actuator. This unified connection approach ensures that environmental factors like heat and vibrations are experienced uniformly across all modules, eliminating the differential effects that occurred when modules were connected through separate mechanical links at different locations.

AI summary
Vehicle headlight comprising at least a first module (1), a second module (2), an actuator (3) for adjusting the modules, and a support structure. Both modules are connected to the support structure through a movable connection. The headlight further comprises an adjusting arm (4) for transferring movement from the actuator (3) to each of the two modules. The adjusting arm (4) extends between the first module (1) and the second module (2) and is connected to the first module (1), to the second module (2) and to the actuator (3).
