Motor Vehicle Container Support with Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing support systems for containers in motor vehicles often transmit noise from moving substances or materials to the vehicle body, causing disturbance during acceleration, deceleration, or driving over uneven surfaces due to firm support, which is not effectively dampened.
Innovation Solution
A support system for motor vehicle containers featuring a frame with elastic and vibration-damping support bodies at spaced-apart fastening points, allowing the container to pass through a vertical opening in the vehicle body while reducing noise transmission and maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the container is firmly supported on the frame, then structural stability and secure mounting are improved, but noise transmission from moving substances to the vehicle body increases
Solution Approach 1:
The patent introduces elastic support bodies as intermediary elements between the container and the frame. These support bodies serve as a mediator that transmits mechanical loads while dampening vibrations and reducing noise transmission. The elastic material absorbs and dissipates vibration energy, preventing direct sound transmission paths from the container to the vehicle body.
Solution Approach 2:
The patent changes the mechanical parameters of the support system by using elastic materials with specific damping characteristics. The support bodies are designed with particular elasticity and vibration-damping properties to optimize the balance between structural stability and noise reduction. This parameter change transforms the support from a rigid connection to a compliant, vibration-absorbing connection.
2Object-generated harmful factors
If elastic support bodies are used to reduce noise, then noise transmission is reduced, but structural rigidity and support strength are weakened
Solution Approach 1:
The patent employs composite support bodies that combine elastic materials with vibration-damping properties. These composite structures integrate materials with complementary characteristics - elasticity for noise reduction and sufficient structural strength for load-bearing. The composite nature allows simultaneous achievement of acoustic isolation and mechanical strength.
Solution Approach 2:
The patent applies elastic support bodies specifically at the fastening points where the container connects to the frame, rather than making the entire structure elastic. This localized application maintains structural rigidity in the frame and container while introducing damping only where needed for noise reduction. The local quality approach preserves overall structural strength while addressing noise transmission at critical interfaces.
Applied Scientific Principles

Function Achieved in This Case
The solution effectively decouples acoustic noise from the vehicle body, preventing disturbing sounds from reaching the passenger compartment and ensuring secure, vibration-damped support for various container types, including fuel tanks and high-voltage batteries, while maintaining watertight and rigid structural integrity.
Implementation Method 1

AI summary
The support has a closed frame (8) fastened and/or supported in an edge area of a vertical through hole (3), which is formed in a rear portion of a motor car. A vertical continuous opening (9) is formed in the frame, and partially aligned with the vertical through hole. A container (1) is inserted into the continuous opening and secured on the frame such that the container partially passes through the through hole. The container is supported on the frame at attachment points (2) in resilient- and vibration absorption manner by an elastic- and vibration damping support body.
