Hydraulic Damper Vehicle Body Reinforcement for Longitudinal Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle body reinforcement methods face challenges in improving ride comfort and reducing vibrations due to space constraints in the engine compartment, limited serviceability, and inability to be easily attached or removed post-manufacture, which restricts longitudinal deformation reinforcement and affects cabin space.
Innovation Solution
A detachable vehicle body reinforcement device with an elongated shape and hydraulic damping force mechanism, positioned laterally on the vehicle frame, allowing easy attachment and removal to enhance longitudinal rigidity and reduce vibrations without altering the existing vehicle configuration, using exposed space outside the passenger compartment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the reinforcement member is positioned in the engine compartment, then the vehicle body can be reinforced, but the serviceability of the engine and other devices is decreased
Solution Approach 1:
The reinforcement member is repositioned from the engine compartment (horizontal plane) to the lower part of the vehicle body (vertical dimension), specifically in the space between the road surface and the underbody. This dimensional shift allows the reinforcement function to be maintained while eliminating interference with engine serviceability.
2Strength
If the reinforcement member traverses the upper space in the engine compartment, then the vehicle body is reinforced, but the serviceability of the engine and other devices is decreased
Solution Approach 1:
The reinforcement member is extracted from the engine compartment space and relocated to the lower vehicle body space. This separation removes the conflicting element from the problematic area while preserving its reinforcing function in a new location where it does not interfere with engine operations.
3Strength
If the reinforcement member is provided in the cabin space, then the vehicle body can be reinforced, but the cabin space is decreased
Solution Approach 1:
The reinforcement member is relocated from the cabin space (upper vertical dimension) to the lower vehicle body space (lower vertical dimension). This dimensional relocation maintains the reinforcing function while preserving the entire cabin volume for passenger use.
4Strength
If the reinforcement member is directed in the lateral direction, then the front part of the vehicle body is reinforced, but the longitudinal deformation is not restricted
Solution Approach 1:
The reinforcement member is configured with asymmetric orientation, extending primarily in the longitudinal direction of the vehicle body rather than symmetrically in both lateral and longitudinal directions. This asymmetric positioning optimizes the reinforcement effect for longitudinal deformation restriction while maintaining adequate lateral support through the lower body mounting structure.
5Strength
If the reinforcement configuration is integrated into the body shell and frame, then the vehicle body is reinforced, but the reinforcement cannot be easily attached or removed
Solution Approach 1:
The reinforcement system is segmented into separate components: the reinforcement member and the mounting structure. This segmentation allows the reinforcement member to be independently attached or removed from the vehicle body, providing adaptability while maintaining the reinforcing function. The mounting structure includes attachment means that enable flexible installation and removal.
Applied Scientific Principles

Function Achieved in This Case
The solution effectively improves ride comfort and restricts vibration generation while maintaining serviceability and cabin space, allowing for adjustable reinforcement based on driver preference without significant changes to the vehicle body configuration.
Implementation Method 1
a hydraulic damper or a rubber member is interposed in the middle of longitudinal direction
Implementation Method 2
the damping force producing means shown in Patent Document 3 uses two elongated frame members that are interconnected by a gap filled with viscoelasticity plastics

AI summary
A vehicle body reinforcement device comprises an elongated shape with its middle portion comprising a hydraulic damper that produces a damping force against longitudinal deformation. Two vehicle body reinforcement devices may be mounted in a longitudinal manner to a vehicle body frame with a lateral space being defined between the two devices. Both ends of each of the vehicle body reinforcement devices can be removably attached from outside of the vehicle to positions that are exposed outside of the passenger compartment and below the vehicle body.
