Headlamp Testing Device Height Adjustment Using a Linear Actuator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjusting the height of a headlight aiming test device (SEP) manually can be difficult and inaccurate due to variations in headlight positions among different vehicles and types, leading to inconsistent measurements.
Innovation Solution
A device with an actuator and processor system that automatically adjusts the SEP's height based on target heights obtained from memory or external data sources, using control commands to move the SEP vertically, optionally with a vertical guide, stop, and relief device, ensuring precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual height adjustment of SEP is used, then device complexity is reduced, but measurement precision and adjustment accuracy deteriorate
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated actuator system controlled by a processor. The actuator mechanically moves the SEP to predetermined heights based on electronic control signals, eliminating the need for manual positioning while achieving precise height settings through electronic control rather than mechanical estimation.
Solution Approach 2:
The system enables self-adjustment by automatically positioning the SEP at the correct height based on stored vehicle data. The processor retrieves target height information and autonomously controls the actuator to achieve proper alignment without requiring user intervention or optical judgment, making the system self-sufficient in the adjustment process.
2Ease of operation
If manual height adjustment of SEP is used, then ease of operation is improved, but adjustment accuracy deteriorates
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated actuator system controlled by a processor. The actuator mechanically moves the SEP to predetermined heights based on electronic control signals, eliminating the need for manual positioning while achieving precise height settings through electronic control rather than mechanical estimation.
Solution Approach 2:
The patent introduces a processor and control system as intermediaries between the user and the SEP positioning mechanism. The processor interprets vehicle data, determines target heights, and translates this information into precise actuator control commands, serving as a mediator that converts simple user input into accurate automated positioning.
3Measurement precision
If automated height adjustment with actuator is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The actuator system serves multiple functions: it positions the SEP at various heights, maintains consistent measurement distances, and adapts to different vehicle types. The processor manages multiple tasks including retrieving vehicle data, calculating target heights, controlling actuator movement, and coordinating with other measurement components, consolidating these functions into integrated control logic.
Solution Approach 2:
The patent implements a hierarchical control structure where the processor contains control logic that manages the actuator, which in turn controls the SEP positioning. The actuator system is nested within the broader measurement system, with the processor nested within the control architecture, creating layered integration where higher-level control manages lower-level execution components.

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables simple and accurate height adjustment of the SEP, ensuring consistent and precise headlight measurements by automating the process and reducing user error.
Implementation Method 1
The actuator can, for example, comprise an electrically driven motor. The actuator can, for example, be a linear actuator.
Implementation Method 2
The actuator can, for example, have a range of motion of more than 50 cm, in particular more than 100 cm or more than 120 cm, and/or, for example, less than 200 cm, in particular less than 150 cm. In some embodiments, the actuator can comprise a spindle that is rotated by a predetermined angle, with the SEP being attachable to an associated spindle nut. The rotation of the spindle can thereby achieve a linear movement of the SEP.
Implementation Method 3
In some embodiments, the actuator may include a gear and a rack.
