Dual-Channel Ventilation Device with Two-Degree-of-Freedom Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ventilation devices in motor vehicles have complex operation mechanisms with multiple controls, making them difficult to use and increasing production costs.
Innovation Solution
A ventilation device with an operating device having two degrees of freedom, allowing for intuitive selection and adjustment of multiple closing devices through linear or rotational movements, reducing the need for multiple controls and incorporating a lighting system for visual feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple separate controls are used for each closing device, then each closing device can be precisely controlled, but the device complexity and number of controls increase
Solution Approach 1:
The patent combines multiple separate controls for different closing devices into a single operating device with multiple degrees of freedom. This single operating device can control both the first closing device (6) and the second closing device (7) through different movement directions, thereby reducing the total number of controls while maintaining the ability to precisely adjust each closing device independently.
Solution Approach 2:
The operating device is designed as a universal control mechanism that can perform multiple functions: it can select between different closing devices and adjust their opening degrees. By having at least two operating degrees of freedom, the single operating device replaces what would traditionally require multiple separate controls, simplifying the user interface while preserving full control capability.
2Adaptability or versatility
If multiple separate controls are used for each closing device, then each function can be independently adjusted, but the production costs increase
Solution Approach 1:
The patent merges multiple control mechanisms into a single operating device structure. This consolidation reduces the number of individual control components that need to be manufactured and assembled, thereby lowering production costs while maintaining the versatility to independently adjust each closing device through different degrees of freedom.
Solution Approach 2:
The operating device is designed as a multi-functional universal control that can handle selection and adjustment of multiple closing devices. This universal design eliminates the need to produce and stock multiple separate control units, reducing manufacturing complexity and costs while preserving full adjustment capability for each ventilation duct.

AI summary
The invention relates to a ventilation device (1, 15) for a motor vehicle, comprising a first ventilation channel (2, 16) for guiding a first air flow through a first ventilation device opening (3, 17) into a motor vehicle interior, a second ventilation channel (4, 18) for guiding a second air flow through a second ventilation device opening (5, 19) into the motor vehicle interior, and a first and a second closing device (6, 20, 7, 21) with a respective degree of openness that can be adjusted between an open and a closed position by an operating device (8, 22), wherein the first closing device (6, 20) closes the first ventilation channel (2, 16) in the closed position and the second closing device (7, 21) closes the second ventilation channel (4, 18) in the closed position, wherein the operating device (8, 22) has at least two degrees of operating freedom (A, B), wherein, by means of the first degree of operating freedom (A), it can be selected which of the closing devices (6, 20, 7, 21) is/are selected for the subsequent adjustment of the degree of openness by the second degree of operating freedom (B), and the degree of openness or the degrees of openness of the selected closing device (6, 20, 7, 21) can be adjusted by means of the second degree of operating freedom (B).
