Headlamp Alignment Holder With Form-Fit Reference Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for checking and adjusting the alignment of motor vehicle headlamps are complex and lack simplicity and reproducibility, particularly in establishing accurate spatial relations between the headlamp and the adjustment apparatus.
Innovation Solution
The proposed alignment checking apparatus holder features a base body with reference markings and form-fit elements that establish spatial connections with the motor vehicle headlamp, allowing for simplified and reproducible alignment checks without the need for optical reference points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If laser sights and optical reference points are used to align the headlamp setting equipment, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex optical alignment systems with simple printed reference markings on a transparent film. The film copies the necessary alignment information in a simplified, visual format that can be directly observed, eliminating the need for laser sights and complex optical reference points while maintaining alignment precision.
Solution Approach 2:
The patent substitutes optical alignment mechanisms (laser sights, optical reference points) with a visual marking system on transparent film. This replacement simplifies the apparatus by eliminating complex optical components while preserving the ability to achieve accurate alignment through direct visual observation of reference markings.
2Measurement precision
If individual alignment of adjustment axis with optical axis is performed, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The transparent film contains printed reference markings that copy the alignment information in a visually accessible format. This allows operators to perform individual alignment tasks by simply observing the markings on the film, making the process both precise and easy to execute without requiring complex alignment procedures.
Solution Approach 2:
The transparent film acts as an intermediary between the headlamp setting equipment and the operator. It provides visual reference markings that mediate the alignment process, enabling operators to achieve accurate alignment through simple visual observation rather than complex adjustment procedures.
3Measurement precision
If complex optical systems are used for alignment checking, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The transparent film with printed reference markings serves as a simplified copying system that replaces complex optical checking apparatus. The markings on the film provide the necessary alignment checking information in a visual format that can be directly observed, eliminating the need for complex optical systems while maintaining checking accuracy.
Solution Approach 2:
The patent replaces complex optical checking systems with a visual marking system on transparent film. This substitution simplifies the checking apparatus by eliminating complex optical components while preserving the ability to achieve accurate alignment verification through direct visual observation of reference markings.

AI summary
An alignment checking apparatus holder to assist checking of the alignment of a motor vehicle headlamp installed in a body of a motor vehicle includes a base body, at least one reference marking on the base body, and a multiple of form-fit elements. The base body is visually perceptible from the outside in a checking position. The multiple of form-fit elements are rigidly connected to the base body and are intended to form form-fit connections with parts of the motor vehicle headlamp or of the body of the motor vehicle. The at least one reference marking has a predetermined position with respect to the multiple of form-fit elements.
