Vehicle Insulating Device with Multi-Directional Lateral Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle insulating devices fail to securely insulate the passenger compartment from noise and moisture originating from the drive region, such as the engine compartment or wheel housing, due to inadequate support and stability, leading to potential loosening or twisting during vehicle operation.
Innovation Solution
A vehicle insulating device with multiple lateral support regions, including first, second, and third support regions, that securely fasten between the vehicle bodywork section and fender, featuring a tub shape with a surrounding rim and bead, and folding edges to ensure a snug fit and prevent twisting, along with optional anti-twisting protection and liquid drainage, utilizing noise-absorbing and moisture-sealing materials like PE-foam and EPDM-foil.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple insulating device is used between bodywork section and fender, then manufacturing cost is reduced, but the device becomes loose and twists during vehicle operation
Solution Approach 1:
The insulating device is divided into multiple functional regions: first lateral support regions for primary positioning, second lateral support regions for angular support, and third lateral support regions for additional stability. This segmentation allows each region to perform its specific function, preventing loosening and twisting while maintaining manufacturing feasibility through modular design
Solution Approach 2:
The insulating device extends in multiple dimensions with lateral support regions distributed along its longitudinal extension. The device has a height corresponding to at least 60% of the fender height and includes support regions at different positions (first, second, and third lateral support regions), creating a three-dimensional structure that resists movement in multiple directions simultaneously
2Ease of manufacture
If the insulating device does not extend sufficiently along the fender height, then manufacturing cost is reduced, but noise and moisture insulation effectiveness deteriorates
Solution Approach 1:
The insulating device is designed to extend to at least 60% of the fender height, providing sufficient insulation coverage without requiring full fender height coverage. This partial extension achieves the necessary insulation effectiveness while reducing material usage and manufacturing cost compared to a full-height device
3Reliability
If multiple lateral support regions are added to prevent loosening and twisting, then positioning stability is improved, but device complexity increases
Solution Approach 1:
Multiple lateral support regions (first, second, and third support regions) are integrated into a single monolithic insulating device structure. The different support regions are combined in one continuous component that can be installed as a single unit, reducing assembly complexity while maintaining the stability benefits of multiple support points

AI summary
A vehicle is provided with a bodywork section, a fender and an insulating device. Between the bodywork section and the fender a free space is formed. The insulating device for noise and/or moisture insulation is arranged between a drive region and a passenger compartment of the vehicle in the free space. The insulating device along its longitudinal extension L comprises first lateral support regions, with which it supports itself on the bodywork section and on the fender. The insulating device comprises second lateral support regions, with which the insulating device supports itself angularly with respect to the longitudinal extension L on the bodywork section and on the fender. The insulating device comprises third lateral support regions, with which the insulating device supports itself parallel to the longitudinal extension and offset in or against the travelling direction F of the vehicle on the bodywork section and on the fender.
