Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle headlights with manually operated and electromotive actuating means for adjusting optically relevant components are costly, space-intensive, and limit the freedom of headlight dimension selection.
Innovation Solution
A vehicle headlight design that eliminates the need for mechanical actuating means by using a measuring device to emit an electrical signal for controlling electromotive actuating means, allowing for efficient and cost-effective adjustment of optically relevant components, with a compact and robust structure, utilizing angular position sensors or potentiometers, and a transmission gear to transmit rotational movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manually operated actuating means are used to adjust optically relevant components, then adjustment functionality is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the manual mechanical coupling elements from the headlight system and replaces them with an electromotive actuating means. The measuring device detects the position of the adjustment element and sends signals to an electromotor that automatically positions the optically relevant component, eliminating the need for manual mechanical linkages while preserving adjustment functionality.
Solution Approach 2:
The patent substitutes the mechanical actuating system with an electromechanical system. Instead of using manual mechanical coupling elements to transmit movement from an adjustment element to a drive shaft, the system uses a measuring device (angular position sensor) combined with an electromotor to achieve the same positioning function, thereby reducing mechanical complexity.
2Ease of operation
If manually operated actuating means with mechanical coupling elements are installed, then adjustment capability is provided, but manufacturing and installation cost increase
Solution Approach 1:
The patent removes complex mechanical coupling elements from the design, which directly reduces manufacturing steps and assembly operations. By using a measuring device coupled to an electromotor, the system requires fewer precision-machined mechanical parts, lowering both manufacturing and installation costs while maintaining adjustment capability.
Solution Approach 2:
The substitution of mechanical actuating means with an electromotive system reduces the number of mechanical components that require precision manufacturing and assembly. The electromotor and sensor system can be more easily manufactured and installed compared to complex mechanical linkages, thereby reducing overall manufacturing and installation costs.
3Ease of operation
If mechanical actuating means are included in the headlight, then adjustment functions are enabled, but headlight dimensions cannot be freely selected
Solution Approach 1:
The patent extracts the bulky mechanical coupling elements from the headlight design and replaces them with a compact electromotive actuating means. The measuring device and electromotor occupy significantly less space than mechanical linkages, allowing the headlight to be designed with more flexible and compact dimensions while preserving full adjustment functions.
Solution Approach 2:
The electromechanical system replaces the space-intensive mechanical actuating means, enabling more freedom in headlight dimensional design. The compact nature of sensors and electromotors allows for smaller overall headlight dimensions or more flexible spatial arrangements compared to systems requiring extensive mechanical linkages.
