Vehicle Air Vent Slat Layout to Prevent Unintended Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ventilation vents for motor vehicles are prone to unintentional adjustment due to contact with occupants, leading to unwanted airflow deflection, and lack cost-effective solutions for precise airflow direction into the passenger compartment.
Innovation Solution
A ventilation vent design featuring pivotable air guide slats mechanically coupled to each other, with shielding slats and a spring device to prevent unintentional adjustment, and a housing that can be integrated with the ventilation duct to direct airflow at a variable angle, using materials like metal and plastic with reinforcing fibers for enhanced stability and deflection.

Engineering Contradiction Analysis
1Measurement precision
If adjustable air guide slats are provided for variable airflow deflection, then the airflow direction can be precisely controlled toward the passenger compartment, but unintentional adjustment becomes easily possible due to inadvertent contact
Solution Approach 1:
A spring device acts as an intermediary between the air guide slat and the housing. The spring provides a restoring force that counteracts inadvertent contact forces, preventing unintentional adjustment while allowing deliberate adjustment when needed. The spring mechanism mediates between external disturbances and the slat position, maintaining reliability without sacrificing adjustability.
Solution Approach 2:
The spring device is pre-loaded to provide a counteracting force against potential inadvertent contact. This preliminary anti-action prevents the slat from moving unintentionally by opposing any external forces before they can cause unwanted adjustment, while still allowing intentional adjustment when the user applies sufficient force.
2Device complexity
If rigid air guide slats are used for constant direction airflow, then the structure is simple and stable, but the airflow direction cannot be adjusted to follow occupants or change conditions
Solution Approach 1:
The air guide slat is made dynamic through the spring mechanism, allowing it to pivot between different angular positions. The spring enables the slat to adapt its position based on operational needs while returning to a default position when not in use, providing both simplicity and adaptability in the ventilation system.
Solution Approach 2:
The system changes the angular parameter of the air guide slat to control airflow direction. The spring mechanism enables this parameter change while maintaining a simple structural design, allowing the slat to assume different positions for different airflow requirements without complex actuation systems.
3Manufacturing precision
If multiple air guide slats are mechanically coupled for synchronous pivoting, then the airflow distribution is uniform and coordinated, but the mechanism becomes more complex and costly
Solution Approach 1:
Multiple air guide slats are mechanically coupled together to form a unified assembly that pivots synchronously. This merging of multiple slats into a single coordinated unit achieves uniform airflow distribution while simplifying the control mechanism, as one adjustment action controls all slats simultaneously rather than requiring individual adjustment mechanisms.
