Vehicle Radiator Shutter Roller Blind Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air duct systems for vehicles require significant space and do not optimally utilize air flows due to flap systems, which can lead to incomplete closure at high speeds, increasing air resistance and risking damage to the roller blind element.
Innovation Solution
A device with a roller blind element supported by a lattice-like support element that can be adjusted between positions to control air flow, minimizing space requirements and ensuring stable closure, using a winding element for adjustment and a smooth, rounded design to prevent damage.

Engineering Contradiction Analysis
1Loss of energy
If a roller blind element is used to close the cooling air inlet at high speeds, then air resistance is reduced, but the roller blind element may be pushed out of the guide by air pressure, causing incomplete closure and increased air resistance
Solution Approach 1:
The support element is divided into multiple sections (first section, second section, third section) that can independently support different portions of the roller blind element. This segmentation allows each section to handle localized air pressure forces, preventing the roller blind element from being pushed out of the guide while maintaining reliable closure at high speeds.
Solution Approach 2:
Different sections of the support element have different structural characteristics optimized for their specific functions. The first section has a first cross-sectional shape, the second section has a second cross-sectional shape, and the third section has a third cross-sectional shape. This local quality variation allows each section to provide appropriate support characteristics for its specific location, ensuring stable roller blind element support under varying air pressure conditions.
2Adaptability or versatility
If flap systems are used to regulate air flow, then air flow can be diverted according to opening angles, but the systems require considerable space in the longitudinal direction when open
Solution Approach 1:
Instead of using flap systems that extend in the longitudinal direction, the invention uses a roller blind element that rolls up and down in the vertical dimension. The support element provides structural support in the longitudinal direction without requiring the roller blind element itself to extend far forward, thus controlling air flow adaptability while minimizing longitudinal space requirements.
3Reliability
If the roller blind element is made stable and resistant, then it can withstand air pressure at high speeds, but the device becomes more complex and costly
Solution Approach 1:
The support element acts as an intermediary between the roller blind element and the air pressure forces. Instead of making the roller blind element itself stable and resistant (which would increase complexity), the support element provides the necessary structural support, allowing the roller blind element to remain simple while still withstanding high-speed air pressure conditions.
