Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation devices for vehicles are not compatible with integration on bumper skins or grids with curves, limiting their ability to manage airflows and engine temperature effectively.
Innovation Solution
A ventilation device with a shutter system featuring a main closing flap and secondary closing flaps that can rotate about different axes, allowing for integration on curved surfaces and improved airflow management in various directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single-axis shutter device is used, then the device structure is simple, but it cannot be integrated on curved bumper skins or grids
Solution Approach 1:
The ventilation device is divided into multiple independent zones (first zone with main closing flap, second zones with secondary closing flaps), each capable of rotating about different axes. This segmentation allows each zone to be independently adapted to curved surfaces while maintaining overall system functionality.
Solution Approach 2:
The invention transitions from a single-axis rotation system to a multi-axis rotation system. The main closing flap rotates about a first axis while secondary closing flaps rotate about a second axis that is different from the first axis, enabling the device to conform to curved geometries by adding rotational freedom in multiple dimensions.
2Adaptability or versatility
If a single-axis shutter device is used, then the device structure is simple, but airflow management in multiple directions is limited
Solution Approach 1:
The shutter device employs multiple closing flaps (main closing flap and secondary closing flaps) that can rotate independently about different axes. This dynamic configuration allows the device to adjust airflow directions adaptively, managing airflows in multiple directions simultaneously based on operational requirements.
Solution Approach 2:
The ventilation device is divided into multiple independent zones (first zone with main closing flap, second zones with secondary closing flaps), each capable of rotating about different axes. This segmentation allows each zone to be independently adapted to curved surfaces while maintaining overall system functionality.
3Adaptability or versatility
If multiple zones with different rotation axes are used, then integration on curved surfaces and multi-directional airflow management are improved, but the device complexity increases
Solution Approach 1:
The multi-axis shutter device serves multiple functions: it can be integrated on curved bumper skins or grids, manage airflows in multiple directions, and regulate temperature of engine and other components. Each closing flap system (main and secondary) can operate independently or in coordination to achieve different airflow patterns and adaptation to various surface geometries.

AI summary
Disclosed is a ventilation device for a vehicle including a frame defining an opening and a closing device of the opening. The ventilation device has a first zone. The closing device includes at least one main closing flap able to close off the first zone and able to rotate about a first axis of rotation extending along a single first direction of rotation. The ventilation device has at least one second zone. The closing device includes at least one secondary closing flap able to close off the second zone and able to rotate about a second axis of rotation extending along a single second direction of rotation for the or each second zone, the second direction of rotation being separate from the first direction of rotation.
