Window Post Trim With Vertical Speaker and Removable Tongue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing designs for motor vehicle bay garnishes compromise sound quality and access to dashboard fixing due to speaker placement, with transverse orientation degrading sound quality and requiring complex dismantling or additional space for replacement.
Innovation Solution
A garnish with a tongue structure that covers dashboard fixing means, includes a variable transverse section, and a vertically oriented grid for sound diffusion, allowing the speaker to be fixed underneath, optimizing acoustic performance and simplifying dashboard access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the speaker is placed in the trim along a transverse axis of the vehicle, then the space in the area is freed up, but the quality of the sound emitted is degraded
Solution Approach 1:
The speaker is oriented in a vertical direction (along the Z axis) rather than along the transverse axis, utilizing the vertical dimension to achieve optimal acoustic performance while maintaining space efficiency in the transverse direction
2Object-generated harmful factors
If the speaker is placed in the dashboard area, then the acoustic performance is optimized, but the access to the means of fixing the dashboard is complicated
Solution Approach 1:
The trim is segmented into a main body and a tongue portion, where the tongue can be removed independently to provide access to the dashboard fixing means, while the speaker remains integrated in the main body of the trim
Solution Approach 2:
The tongue is designed as a removable component that can be taken out to access the dashboard fixing means, separating the access function from the main trim structure while keeping the speaker integrated
3Shape
If the dashboard fixing means are covered by the trim, then the aesthetic appearance is improved, but the access to the fixing means is restricted
Solution Approach 1:
The trim is divided into a main body that covers the fixing means for aesthetic purposes and a removable tongue that provides access when needed
Solution Approach 2:
The tongue is designed to be removable, transforming the trim from a static covering to a dynamic structure that can be opened for access and closed for aesthetic appearance
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances sound quality by orienting the speaker vertically and facilitates easier dashboard removal and installation by providing a tool passage surface, improving both acoustic performance and access convenience.
Implementation Method 1
the tongue includes, in its thickness oriented along a vertical direction of the vehicle, a grid configured to diffuse sounds generated by the loudspeaker

AI summary
A trim (18) for a motor vehicle window post (12) comprises a lower portion (19) configured to be integrated into an instrument panel (14) of the vehicle. The bottom portion of the trim includes a tab (20) extending in a longitudinal direction (X) and a transverse direction (Y) of the vehicle, said tab being configured to support a loudspeaker oriented in a vertical direction (Z) of the vehicle.
