Vehicle Stabilizer Bush Bracket Overlap for Crushable Zone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The arrangement of brackets and bushes in a vehicle's front compartment can lead to an insufficient crushable zone when they are positioned close to each other in the front-rear direction, necessitating an enlargement of the compartment, which restricts design freedom.
Innovation Solution
The configuration of the vehicle includes a first bush located frontward of the drive and a first bracket positioned rearward of the bush, with at least part of the bracket located above the bush, allowing their overlapping spaces to ensure a sufficient crushable zone without enlarging the compartment, enhancing the stiffness of the stabilizer against bending and twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the bushes and brackets are arranged in proximity to each other in the front-rear direction, then the space utilization is improved, but the crushable zone becomes insufficient
Solution Approach 1:
The patent transitions from a one-dimensional front-rear arrangement to a three-dimensional configuration where the bracket is positioned above the bush. This vertical stacking allows the components to occupy overlapping spaces in the front-rear direction while maintaining adequate horizontal separation, thus preserving the crushable zone while improving space utilization.
Solution Approach 2:
The bracket is positioned to overlap with the bush in the front-rear direction, creating a nested spatial arrangement where one component's space encompasses part of the other's space. This nesting allows compact packaging without compromising the crushable zone, as the components are staggered vertically rather than linearly arranged.
2Reliability
If the front compartment is enlarged to provide a sufficient crushable zone, then the crushable zone is improved, but the design freedom is limited
Solution Approach 1:
By utilizing the vertical dimension to position the bracket above the bush, the patent maintains the original front compartment dimensions while achieving adequate component separation. This eliminates the need to enlarge the front compartment, thereby preserving design freedom for aesthetic appearance and packaging.
3Area of stationary object
If the bracket is positioned above the bush, then the space overlap is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent divides the mounting structure into separate bush and bracket components with distinct functions. The bush provides vibration isolation and positioning, while the bracket provides structural support and mounting. This segmentation allows each component to be manufactured independently using standard processes, reducing overall manufacturing complexity despite the three-dimensional arrangement.
