Vehicle Corner Lighting with a Hidden Side Marker Reflector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting devices for vehicles have a visible side marker reflex reflector from a front viewing angle, which affects the aesthetic appearance.
Innovation Solution
The side marker reflex reflector is positioned behind at least part of the light module, ensuring it is not visible from the front and only detectable from a side angle, with specific angles of reflection and arrangement to maintain functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the side marker reflex reflector is arranged in front of the light module in the main beam direction, then the side marker function is clearly visible and functional, but the reflector becomes recognizable from the front viewing direction, degrading the aesthetic appearance
Solution Approach 1:
The side marker reflex reflector is repositioned from the front viewable area to the rear side of the light module, utilizing the depth dimension of the housing. This spatial relocation allows the reflector to perform its side marking function while remaining hidden from front viewing angles, thus resolving the contradiction between functionality and aesthetics.
2Shape
If the side marker reflex reflector is positioned behind the light module, then the aesthetic appearance is improved by hiding the reflector from front view, but the reflector's visibility and functionality from side angles must be maintained
Solution Approach 1:
The housing structure is designed with differentiated local qualities: the front region provides aesthetic coverage by hiding the reflector, while the side and rear regions provide optical pathways and viewing angles that maintain the reflector's functionality. The lens and housing geometry are specifically configured to allow side viewing of the reflector while blocking front viewing.
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
The side marker reflex reflector remains hidden from the front view, enhancing the device's appearance while maintaining its signaling function through controlled lateral reflection.
Implementation Method 1
A side marker reflex reflector extending in the main beam direction and containing reflex reflector elements for side marking of the vehicle is arranged in the housing
