Vehicle Radiator Grille Flap Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiator grille arrangements for vehicles face challenges in handling and coating processes, leading to potential damage and inefficiencies in production and operation.
Innovation Solution
A radiator grille arrangement featuring a two-part flap frame that securely holds closure flaps, sliding bolts, and actuating drives, allowing for improved handling during production and reducing the risk of damage by serving as a painting fixture, with components attached in a non-positive, positive, or firmly bonded manner to the support frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If closure flaps are arranged separately on the support frame, then individual handling and adjustment are possible, but handling during production becomes difficult and damage risk increases
Solution Approach 1:
The patent combines the closure flaps, sliding bolt, and actuating drive into a single integrated flap frame assembly. This merging of previously separate components into one unified structure enables easier handling during production and painting processes, while the modular nature of the flap frame allows it to be attached to the support frame as a complete unit, resolving the contradiction between ease of handling and device complexity.
2Ease of manufacture
If closure flaps are handled separately during painting, then precise coating is possible, but handling complexity increases and damage risk rises
Solution Approach 1:
By integrating the closure flaps and actuating mechanisms into a single flap frame, the painting process can be performed on the entire assembly as one unit. This eliminates the need to handle individual flaps during painting, reducing the risk of coating damage while maintaining manufacturing efficiency. The flap frame acts as a protective carrier during the painting process.
Solution Approach 2:
The flap frame is designed to hold the closure flaps in their final positions before painting occurs. This preliminary arrangement ensures that all components are properly positioned and protected before the painting process begins, preventing damage that would occur if components were handled separately during painting.
3Stability of the object's composition
If components are attached firmly to the support frame, then structural stability is improved, but adaptability and ease of repair are reduced
Solution Approach 1:
The patent segments the radiator grille system into distinct modular components: the support frame, the flap frame assembly (containing closure flaps and actuating mechanisms), and the actuating drive. The flap frame can be attached to the support frame through various methods (non-positive, positive, or bonded connections), allowing the system to maintain structural stability while enabling easy removal and repair of individual modules without affecting the entire structure.

AI summary
A radiator grille arrangement for a vehicle is disclosed. The grille arrangement has at least one support frame surrounding a primary air inlet, a number of closure flaps which are mounted for rotation around a flap rotation axis between a closed position and an open position, where flap levers are molded or formed on the closure flaps, the flap levers being operatively connected to a sliding bolt, and an actuating drive for positioning the closure flaps. A flap frame is provided for receiving the closure flaps, the sliding bolt and the actuating drive, where the flap frame is formed in two parts and is able to be attached to the support frame of a radiator shield in a non-positive, positive and/or firmly bonded manner.
