Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle trim elements face a challenge in integrating large functional components while maintaining aeration device outlets, as the space requirements for these outlets conflict with the increasing size of functional components.
Innovation Solution
The trim element design incorporates an aerator with a gas flow diffusion opening that extends around the periphery of at least a portion of the functional component, minimizing the size of the aeration device outlets while allowing for effective aeration and controlled gas flow directionality via the Coanda effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional aeration device outlets are used to provide gas flow directionality, then effective aeration and directional control are achieved, but the space required on the trim element increases, limiting the size of functional components
Solution Approach 1:
The gas flow diffusion opening extends around the periphery of the functional component in a three-dimensional arrangement, utilizing the vertical and lateral dimensions rather than relying on a traditional planar outlet. This dimensional transformation allows the aerator to achieve effective gas flow distribution and directional control without occupying excessive horizontal space on the trim element surface.
Solution Approach 2:
The aerator is integrated around the periphery of the functional component, with the gas flow diffusion opening enveloping the functional component's edges. This nested arrangement allows the aeration system to be embedded within the overall trim element structure, minimizing the space required while maintaining aeration effectiveness.
2Ease of operation
If the size of functional components is increased to improve display readability and storage volume, then passenger comfort and ergonomics are enhanced, but the space available for aeration device outlets is reduced
Solution Approach 1:
By transforming the outlet configuration from a traditional planar arrangement to a three-dimensional peripheral diffusion opening that extends around the functional component, the invention enables larger functional components to be accommodated while maintaining adequate aeration capability through vertical and lateral gas flow distribution.
Solution Approach 2:
The periphery-extended gas flow diffusion opening serves multiple functions simultaneously: it provides effective aeration, enables directional gas flow control via the Coanda effect, and accommodates larger functional components. This multi-functional design resolves the space conflict by making the aeration system adaptable to various functional component sizes.
3Area of stationary object
If aeration outlets are minimized in size to accommodate large functional components, then space for functional components is improved, but gas flow directionality may be compromised
Solution Approach 1:
The invention compensates for the reduced size of individual outlets by extending the gas flow diffusion opening in three dimensions around the functional component periphery. This spatial extension maintains gas flow directionality capability through the Coanda effect while accommodating larger functional components.
Solution Approach 2:
The invention utilizes the Coanda effect to change the gas flow parameters, enabling the gas flow to adhere to curved surfaces and follow the periphery of the functional component. This physical effect allows directional control of gas flow even through minimized outlet sizes, as the flowing gas naturally follows the contour of the surrounding surfaces.

AI summary
A vehicle trim element having at least one functional component and at least one aerator of the vehicle compartment. The aerator includes at least one duct for conveying a gas flow defining an opening for diffusing the gas flow, the conveying duct extending in a main direction. The aerator is arranged to diffuse a gas flow in the passenger compartment of the vehicle in a diffusion direction in which the gas flow is diffused and which is variable by Coanda effect, between a first diffusion direction and a second diffusion direction that is different from the first diffusion direction. The opening for diffusing the gas flow extends around the periphery of at least one portion of the functional component.
