Headlamp Assembly Flange Gap Occlusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headlamp assemblies for saddle-type vehicles face challenges in maintaining a large light-emitting area for upper lamps while minimizing the visibility of the gap between upper and lower lamps, which affects design freedom and external appearance.
Innovation Solution
The design incorporates a flange portion extending downwardly from the lower edge of the upper reflector, with the extension member approaching the front end of the lower edge, and vertically aiming axes of both lamps adjusted to be near the flange portion, ensuring the gap is hard to see and allowing for aiming adjustments without significant movement, thus enhancing design flexibility and appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the extension member is arranged to approach the front end of the lower edge of the upper reflector, then the gap between upper and lower lamps becomes hard to see, but the light-emitting area of the upper lamp is decreased
Solution Approach 1:
The upper reflector is segmented into two functional parts: the main reflective surface and the downwardly extending flange portion. This segmentation allows the flange to serve as a visual occluder for the gap while the main reflector surface preserves the light-emitting area, resolving the contradiction between appearance and functionality.
Solution Approach 2:
The flange portion acts as an intermediary element between the upper reflector and the extension member. It provides a downward extension that visually bridges the gap area without requiring the extension member to intrude into the light-emitting zone, thus mediating between aesthetic requirements and functional constraints.
2Shape
If the flange portion extends downwardly from the lower edge of the upper reflector, then the gap becomes hard to see, but the design complexity increases
Solution Approach 1:
The flange portion is merged with the upper reflector as an integrated structure rather than a separate component. This merging approach allows the flange to be formed simultaneously with the reflector during manufacturing, reducing assembly steps and overall design complexity while achieving the visual occlusion effect.
Solution Approach 2:
The flange portion serves multiple functions: it visually occludes the gap between lamps, provides structural support for positioning the extension member, and maintains the integrity of the upper reflector assembly. This multi-functionality reduces the need for additional components, thereby simplifying the overall design.

Function Achieved in This Case
This configuration ensures a larger light-emitting area for the upper lamp, simplifies the design of the flange portion, and maintains the external appearance of the lower lamp by making the concave surface portion of the second reflector invisible through the gap, enhancing the overall aesthetic and functional aspects of the headlamp assembly.
Implementation Method 1
a first reflector (116) which reflects light from the first light source (114) toward a front side
Implementation Method 2
a second reflector (120) which reflects light from the second light source (118) toward the front side

AI summary
A headlamp assembly for a saddle-type vehicle ensures a generous light-emitting area of an upper lamp, and can make a gap formed between upper and lower lamps hard to see. The headlamp assembly includes upper and lower lamps, each including a light source and a reflector, with the lower lamp arranged below the upper lamp. The headlamp assembly also includes extension members, which extend in a substantially horizontal direction and approach front ends of the reflectors from a front side thereof, where flange portions are attached to and extend downwardly from the lower edges of the reflectors.
