Corner Reflector Layout Hidden Behind a Lamp Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner reflector installations in vehicles, especially in lamps like headlights, compromise vehicle appearance and are prone to performance deterioration due to moisture and dust adhesion, with no effective solution for discreet integration.
Innovation Solution
A corner reflector installation structure that positions the corner reflector inside the lamp housing, using a cover member to overlap with it, and strategically inclines and positions the reflector relative to the substrate and heat sink to prevent adhesion and maintain reflection performance while avoiding visual recognition from outside.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the corner reflector is installed inside a lamp, then the reflection performance is protected from moisture and dust adhesion, but the vehicle appearance deteriorates if the corner reflector is visually recognized from outside
Solution Approach 1:
The corner reflector is nested inside the lamp housing, positioned behind the cover member. The cover member acts as an outer shell that conceals the corner reflector while allowing it to function. This nesting arrangement protects the corner reflector from environmental factors while maintaining vehicle appearance by hiding the reflector from external view.
Solution Approach 2:
The solution transitions from a two-dimensional surface mounting to a three-dimensional internal positioning. The corner reflector is placed in the depth dimension behind the cover member, creating an overlapping relationship in front view. This spatial repositioning allows the reflector to be functionally integrated while visually concealed.
2Shape
If the corner reflector is positioned to overlap with the cover member in front view, then vehicle appearance is maintained, but the installation space and positioning precision requirements increase
Solution Approach 1:
The cover member serves multiple functions: it acts as the lamp's protective cover, provides the visual concealment for the corner reflector, and establishes the overlapping positional relationship in front view. By making the cover member multi-functional, the patent avoids adding separate concealment structures, thereby reducing overall device complexity.
Solution Approach 2:
The patent merges the corner reflector installation structure with the existing lamp housing and cover member. Instead of creating a separate mounting system, the corner reflector is integrated into the lamp's existing structure, sharing the cover member and housing space. This merging approach simplifies the overall installation structure.
3Volume of moving object
If the corner reflector is positioned close to the substrate with metal components, then the lamp dimensions are reduced, but the reflection performance may be affected by metal interference
Solution Approach 1:
The patent applies local quality by creating a metal-free zone around the corner reflector. The substrate with metal components is deliberately positioned outside the overlapping area of the corner reflector in front view. This localized spatial separation ensures that metal components do not interfere with the radio wave reflection while maintaining compact overall dimensions.

Function Achieved in This Case
Prevents deterioration of reflection performance and maintains vehicle appearance by ensuring the corner reflector is not visually recognizable, while enhancing installation flexibility and heat management, and reducing the overall dimensions of the lamp.

AI summary
In a corner reflector installation structure that is applicable to a vehicle including: a lamp; a cover member that covers a part of the lamp; and a corner reflector, the corner reflector is provided inside a housing constituting the lamp. The corner reflector installation structure is configured such that that the cover member and the corner reflector overlap with each other in a front view of a vehicle body. The cover member is inclined such that a vehicle body upper side of the cover member is located backward relative to a vehicle body lower side of the cover member in a side view of the vehicle. The cover member is inclined such that a vehicle body lower side of the cover member is located backward relative to a vehicle body upper side of the cover member in a side view of the vehicle.
