Vehicle Console Mounting Bracket Impact Absorption Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional console unit mounting brackets in vehicles are rigid and unable to absorb impact energy, leading to potential misalignment or damage during vehicular impacts, as they lack the necessary flexibility to distribute lateral and vertical forces effectively.
Innovation Solution
The mounting bracket design includes a base support component with a vertically extending back support portion and angled side component plates that form an impact absorbing section, allowing for deformation to dissipate impact energy and provide both rigidity and flexibility, thereby protecting the console unit and its occupants from impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the mounting bracket uses a rigid central leg structure to secure the console, then the console stability is improved, but the ability to absorb impact energy deteriorates
Solution Approach 1:
The mounting bracket transitions from a static rigid structure to a dynamic structure capable of deformation during impact. The side walls are designed to bend and deform under lateral forces, allowing the bracket to adapt its rigidity based on loading conditions - rigid during normal use for stability, flexible during impact for energy absorption.
Solution Approach 2:
The mechanical properties of the mounting bracket are changed by modifying the side wall geometry to include features that enable controlled deformation. The side walls are designed with specific thickness and curvature parameters that allow them to remain rigid under normal conditions but deform plastically or elastically under impact loads, changing the bracket's overall stiffness parameter dynamically.
2Force
If the mounting bracket is designed with rigid sidewalls to support lateral forces, then the console lateral support is improved, but the lateral deformation capability to absorb forces deteriorates
Solution Approach 1:
The side walls are designed with dynamic characteristics that allow them to transition between rigid and flexible states. During normal operation, they provide rigid lateral support, but during impact, they can deform laterally to absorb energy, thus adapting their mechanical behavior based on the applied load magnitude and rate.
3Stability of the object's composition
If the console unit is rigidly mounted to provide stability, then the console firmness is improved, but the shock absorption capability deteriorates
Solution Approach 1:
The mounting bracket's structural parameters are optimized to provide different levels of rigidity for different functions. The base and central leg are designed with higher rigidity parameters for stability, while the side walls are designed with lower rigidity parameters to enable shock absorption through deformation, creating a multi-parameter structural system with differentiated mechanical properties.

AI summary
A mounting bracket to hold a console frame member includes a base support component, a first side component plate, and a second side component plate. The base support component includes a base portion and a back support portion having a first end and a second end. The base portion is fixed to a floor of a vehicle and the back support portion vertically extends from the base portion. The first side component plate and second side component plates extend toward a front side of the mounting bracket from the first end and the second end. The base support component, the first side component plate, and the second side component plate collectively form an impact absorbing section.
