Vehicle Lamp Shielding Layout for Hidden Road Surface Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicular lamps face restrictions in the arrangement position of the road surface irradiation unit due to the visible glowing of the projection lens, which affects the design quality and functionality, particularly when viewed from the front.
Innovation Solution
Incorporating a shielding part that covers the projection lens of the road surface irradiation unit when viewed from the front, allowing for increased flexibility in the arrangement position and timing of the unit relative to other lamp units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projection lens is used as the light emitting portion for road surface irradiation, then the irradiation pattern can be formed on the road surface, but the projection lens becomes visible and glows when viewed from the front, restricting the arrangement position of the road surface irradiation unit
Solution Approach 1:
A shielding part is introduced as an intermediary element between the projection lens and the front view direction. This shielding part blocks the visibility of the glowing projection lens while allowing the irradiation function to operate normally, thus resolving the conflict between forming the irradiation pattern and preventing the projection lens from being visible
Solution Approach 2:
The road surface irradiation unit is segmented into functional components: the projection lens for forming the irradiation pattern and the shielding part for controlling visibility. This segmentation allows independent optimization of each component's function and position, enabling the irradiation unit to be placed in positions that would otherwise be restricted by visibility concerns
2Ease of manufacture
If the road surface irradiation unit is positioned freely in the lamp chamber, then design flexibility is improved, but the glowing projection lens becomes visible from the front, affecting design quality
Solution Approach 1:
The shielding part serves as a mediator that decouples the design flexibility from design quality constraints. It allows the irradiation unit to be positioned freely for manufacturing and design ease while maintaining aesthetic design quality by preventing the projection lens from being visible from the front
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 shielding part prevents the projection lens from being visible, enhancing the design quality and providing greater freedom in arranging the road surface irradiation unit, enabling it to be positioned and operated independently of other lamp units without compromising the irradiation pattern.
Implementation Method 1
a display pattern projection part as a road surface irradiation unit with a light source and a projection lens is provided in a lamp chamber, and light emitted from the light source is projected by the projection lens to form an irradiation pattern
Implementation Method 2
a shielding part for covering the light emitting portion for the road surface when the road surface irradiation unit is viewed from the front

AI summary
To provide a vehicular lamp that can improve the degree of freedom in the arrangement position of a road surface irradiation unit. The vehicular lamp comprises a road surface irradiation unit for forming an irradiation pattern around the vehicle with light from a light emitting portion for a road surface; and a shielding part for covering the light emitting portion for the road surface when the road surface irradiation unit is viewed from the front. The vehicular lamp may further comprise a lamp unit housed in a lamp chamber together with the road surface irradiation unit, and the road surface irradiation unit may be turned on and off interlocked with the lamp unit.
