Grille Shutter Lamella Mounting for Easy Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grille shutter assemblies for vehicles face issues with lamella mounting and deformation during installation, making it difficult to replace or repair damaged components.
Innovation Solution
A grille shutter assembly design featuring a mounting pin at one end and a C-shaped arm at the other end, with a coupling link that allows easy attachment to the grille frame without bending, using a protrusion and receptacle opening for secure mounting and a locking assembly for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lamella is mounted by bending it to engage pins in holes on opposite sides of the grille frame, then the lamella can be securely attached to the frame, but the lamella may deform or get damaged during mounting
Solution Approach 1:
The mounting system is divided into separate components: the lamella body, the C-shaped arm attachment at one end, and the coupling link with protrusion at the other end. This segmentation allows each component to be manufactured independently without deformation, while still achieving secure attachment when assembled together.
Solution Approach 2:
The coupling link acts as an intermediary element between the C-shaped arm and the grille frame. Instead of directly bending the lamella to engage pins, the coupling link with its protrusion mediates the connection, allowing the lamella to be mounted securely without deformation or damage.
2Ease of operation
If the lamella is designed with a simple pin-and-hole mounting system, then the mounting process is simple, but the lamella cannot be easily removed or replaced
Solution Approach 1:
The mounting system transitions from a static permanent attachment to a dynamic removable connection. The C-shaped arm and coupling link design allows the lamella to be easily inserted and removed from the grille frame, enabling maintenance and replacement while maintaining operational simplicity.
Solution Approach 2:
The design allows the lamella to be easily discarded (removed) from the grille frame when needed for replacement or maintenance, and then recovered (reinstalled) using the same simple C-shaped arm and coupling link mechanism, facilitating easy repair and maintenance.
3Reliability
If additional parts are used to mount the lamella onto the frame, then the mounting is more secure, but the mounting process becomes more complex
Solution Approach 1:
The C-shaped arm and coupling link are integrated into the lamella structure itself, combining the mounting function with the lamella body. This merging eliminates the need for separate additional mounting parts, achieving secure attachment while keeping the mounting process simple and the overall device complexity low.
