Center Console Soundproofing for Vehicle Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle designs that incorporate high-voltage batteries in center consoles struggle to effectively suppress noise transmission to passengers, and previous solutions are either difficult to implement or not applicable to center console configurations.
Innovation Solution
A sheet-like soundproofing member, integrated with noise absorbing and heat insulating materials, is placed between the electric device and the center console, covering joint portions between frame members to prevent noise leakage and heat transfer, while an air conditioning duct is positioned above the soundproofing member to further suppress noise and heat transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a noise absorbing material is built to the interior surface of the inner case, then noise transmission is suppressed, but it becomes difficult to build the noise absorbing material
Solution Approach 1:
The patent applies a sheet-like soundproofing member that can be easily attached to the inner case surface. This flexible sheet structure allows for simple installation compared to building rigid noise absorbing materials, while effectively suppressing noise transmission from the high-voltage battery to the passenger compartment.
Solution Approach 2:
The soundproofing member is constructed as a composite material that integrates both noise absorbing properties and heat insulating properties. This composite structure achieves multiple functions (noise suppression and thermal insulation) simultaneously while maintaining ease of installation as a pre-fabricated sheet component.
2Adaptability or versatility
If high-voltage electric equipment is disposed in a center console, then space is utilized, but noise is transmitted to a passenger
Solution Approach 1:
The patent introduces a soundproofing member as an intermediary element between the high-voltage battery (noise source) and the passenger compartment. This intermediate layer effectively blocks noise transmission while allowing the high-voltage equipment to remain positioned in the center console for optimal space utilization.
3Object-affected harmful factors
If a sheet-like soundproofing member is disposed between the upper surface of the electric device and the center console, then noise transmission is suppressed, but the structure becomes more complex
Solution Approach 1:
The patent employs a thin sheet-like soundproofing member that can be easily installed between the electric device and center console. This thin-film approach suppresses noise transmission while adding minimal structural complexity compared to more substantial soundproofing constructions.
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 effectively reduces noise and heat transmission to passengers, making it easier to implement and ensuring noise is shut out from gaps in the frame member joints, while preventing condensation on the air conditioning duct.
Implementation Method 1
a sheet-like soundproofing member is disposed between an upper surface of the electric device and the center console
Implementation Method 2
the soundproofing member is made up by integrating or laminating a noise absorbing member and a heat insulating member
