Daytime Running Light Assembly With Flush Bumper Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing daytime running lights on motor vehicles are typically attached to the bumper reinforcement, making it difficult to achieve a flush fit between the glass and the bumper skin, which negatively impacts the perceived quality of the vehicle.
Innovation Solution
A daytime running lighting assembly that includes a light module with a housing and glass, where the glass is supported by a fold in the bumper skin and a protruding lug that inserts into a slot, allowing for precise alignment and immobilization, thereby enabling a flush integration with the bumper skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the daytime running light is fixed to the bumper reinforcement, then the light module is securely immobilized in multiple directions, but the glass of the daytime running light cannot be made flush with the skin of the bumper
Solution Approach 1:
The fixing system is divided into two independent parts: (1) fixing studs on the bumper reinforcement that secure the light module housing in the longitudinal direction, and (2) a separate fixing Lug on the glass that engages with a slot in the skin to ensure flush positioning. This segmentation allows each part to optimize its function without compromising the other.
Solution Approach 2:
The skin acts as an intermediary element between the bumper reinforcement and the glass. The skin has an opening that receives the light module and a slot that receives the Lug, mediating the connection between the structural reinforcement and the optical component to achieve both secure fixing and flush appearance.
2Stability of the object's composition
If the daytime running light is attached to the bumper reinforcement, then the installation is structurally stable, but the perceived quality of the vehicle is reduced due to poor aesthetic integration
Solution Approach 1:
The fixing function is segmented between the bumper reinforcement (providing structural stability through fixing studs) and the skin (providing aesthetic integration through the slot and opening configuration). This allows the structural and aesthetic requirements to be satisfied by different components.
Solution Approach 2:
The skin serves as an intermediary that translates the structural mounting from the reinforcement into an aesthetically pleasing flush integration. The opening and slot in the skin mediate between the structural needs of the reinforcement and the appearance needs of the vehicle body.
