Universal DRL Module Hooking for Headlamp Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of daytime running light (DRL) modules into motor vehicle headlight housings is challenging due to the need for precise positioning and reliable sealing, especially since halogen and LED headlight housings have structurally different housings with identical peripheral grooves for fixing the lens, complicating the assembly process and requiring separate DRL module housings for each type.
Innovation Solution
A daytime signaling module with hooking members on its upper and side edges that fit into the peripheral groove of the headlight housing, along with a central notch for a support tab on the glass, allowing for secure retention and alignment within the headlight housing, enabling the same module to be compatible with both halogen and LED headlight housings without modifying the style or compromising reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate DRL module housings are produced for halogen and LED headlight housings, then the integration is adapted to each type, but the device complexity and manufacturing cost increase
Solution Approach 1:
The DRL module housing is designed with a universal attachment member that can be integrated into both halogen and LED headlight housings. The attachment member features a standardized configuration with fixing tabs that cooperate with the identical peripheral groove structure found in both headlight types, allowing a single DRL module design to serve multiple headlight configurations without requiring separate housing variants.
2Reliability
If precise positioning and perfect integration are required for module assembly, then the sealing and appearance are reliable, but the assembly operation becomes delicate and time-consuming
Solution Approach 1:
The attachment member is pre-formed with fixing tabs and attachment features that are designed to automatically align with the peripheral groove structure during assembly. The longitudinal stiffening rib and fixing tab configuration are prepared in advance to guide the DRL module into correct positioning, eliminating the need for delicate manual adjustment during the assembly process while ensuring reliable sealing and appearance.
3Stability of the object's composition
If the DRL module is fixed after assembly on the vehicle structure, then the positioning is fixed, but the adjustment and repositioning become impossible
Solution Approach 1:
The attachment member employs a dynamic fixing mechanism where the fixing tabs engage with the peripheral groove through a snap-fit or interference fit design. This allows the DRL module to be easily installed and removed by simple insertion and extraction motions, providing both stable positioning during operation and ease of repositioning or repair when needed, without requiring complex fastening operations.
