Vehicle Headlight Leveling Device Symmetrical Terminal Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle headlight leveling devices have asymmetrical terminal layouts for left and right headlights, making it difficult to achieve common specifications and designs for connectors and harnesses.
Innovation Solution
A vehicle headlight leveling device with a housing unit, motor, shaft, and driving-force transmitting mechanism, where the motor's output shaft is perpendicular to the shaft, and terminals are symmetrically arranged, allowing for a common design and layout of connectors and harnesses between left and right headlights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the motor and terminals are arranged on different sides with respect to the virtual surface that includes the shaft, then the leveling device can function properly, but the terminal positions become asymmetrical between left and right headlights, resulting in different connector and harness designs
Solution Approach 1:
The patent applies asymmetry principle by intentionally arranging the motor and terminals on different sides of the virtual surface to ensure proper functioning of the leveling device. This asymmetric arrangement is accepted as necessary for functionality, and the patent addresses the resulting asymmetry between left and right headlights through standardized connector and harness designs that can accommodate both configurations.
2Reliability
If the motor and terminals are arranged on different sides with respect to the virtual surface that includes the shaft, then the leveling device can function properly, but the positions of connectors and lengths of harnesses differ between left and right headlights
Solution Approach 1:
The patent applies universality principle by designing connectors and harnesses that can serve both left and right headlights despite the asymmetric arrangement of motor and terminals. The connector and harness designs are made universal so that the same components can be used in both left-side and right-side vehicle headlights, achieving common specifications and simplifying manufacturing.
3Reliability

AI summary
An axial direction (V2) of an output shaft (23) of a motor (11) is perpendicular to an axial direction (V1) of a shaft (12) that moves back and forth with respect to a housing unit (9, 10). A plurality of power-supplying terminals (14) is symmetrically arranged with respect to a vertical line (V3) passing through a center of the shaft (12) .
