Vehicle Bumper Reinforcement with Integrated Hydraulic Damper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle bumper reinforcement members increase production costs and complexity by requiring additional assembly procedures for vibration damping, which can deteriorate riding comfort due to generated vibrations.
Innovation Solution
A vehicle bumper with integral vibration damping integrated into the reinforcement, featuring a tubular metal structure with a hydraulic damper disposed within, allowing for removability and attachment above or below the reinforcement, reducing assembly procedures by incorporating the damping mechanism into the bumper reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a separate vehicle body vibration damper is attached to the vehicle body frame, then vibration damping performance is improved, but the number of assembly procedures increases and production cost increases
Solution Approach 1:
The patent combines the vibration damping function with the bumper reinforcement by integrating a vibration damping portion into the bumper reinforcement structure. This allows the bumper reinforcement to simultaneously provide structural support and vibration damping, eliminating the need for a separate vibration damper assembly procedure.
Solution Approach 2:
The bumper reinforcement is designed to perform multiple functions: it provides structural reinforcement to the vehicle body and simultaneously acts as a vibration damping component through the integrated vibration damping portion. This multi-functionality reduces the total number of components and assembly steps required.
2Object-affected harmful factors
If a separate vehicle body vibration damper is attached to the vehicle body frame, then vibration damping performance is improved, but production cost increases
Solution Approach 1:
The vibration damping function is merged into the bumper reinforcement structure, reducing the total component count and associated manufacturing costs. The integrated design eliminates the need for separate procurement, inventory management, and assembly of a dedicated vibration damper.
