Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle suspension assemblies, particularly double wishbone suspensions, face challenges in assembly complexity, precision requirements, and limited space, which complicates the integration of components and affects their movement and interference within the vehicle's frame.
Innovation Solution
A vehicle suspension assembly design featuring longitudinally spaced pivot connections for control arms and a shock absorber, with a sway bar connected to both suspension assemblies, utilizing a suspension support system that includes upper and lower control arms, a knuckle, and a shock absorber, where the sway bar is pivotally connected to the suspension supports and supported by pillow blocks, allowing for efficient assembly and movement within limited space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If control arms and shock absorbers are connected to different frame members at multiple positions, then the suspension assembly achieves proper geometric alignment and movement, but the assembly process becomes complex and time-consuming with tight tolerance requirements
Solution Approach 1:
The patent combines multiple connection functions into a single integrated suspension support structure. Instead of connecting control arms and shock absorbers to separate frame members at multiple positions, the suspension support serves as a unified mounting structure that consolidates these connections, thereby reducing assembly complexity while maintaining proper geometric alignment
Solution Approach 2:
The suspension support structure performs multiple functions: it serves as a mounting point for both control arms and the shock absorber, provides structural support, and establishes proper geometric relationships. This multi-functional design reduces the number of separate components and simplifies the overall assembly process
2Volume of moving object
If suspension components are arranged in limited space, then the vehicle's space utilization improves, but component movement and interference avoidance become more difficult
Solution Approach 1:
The patent optimizes component arrangement by utilizing three-dimensional space efficiently. The suspension support structure is designed to position control arms and the shock absorber in different spatial dimensions, allowing sufficient movement range while maintaining compact overall dimensions for better space utilization
3Manufacturing precision
If tight tolerances are used in manufacturing and assembly, then the geometric alignment and performance of the suspension assembly improve, but the assembly time and cost increase
Solution Approach 1:
By consolidating multiple connection points into the integrated suspension support structure, the patent reduces the number of separate assembly operations required. This minimizes the cumulative effect of tolerances and reduces overall assembly time while maintaining the necessary geometric alignment through the unified structure's inherent design

AI summary
A vehicle has a frame and left and right suspension assemblies connected to the frame. Each suspension assembly has a suspension support connected to the frame; a lower control arm having an inner end pivotally connected to the suspension support at two longitudinally spaced positions; an upper control arm having an inner end pivotally connected 5 to the suspension support at two longitudinally spaces positions; a knuckle pivotally connected to outer ends of the lower and outer control arms; and a shock absorber having an upper end pivotally connected to the suspension support and a lower end pivotally connected to one of the lower and upper control arms. A sway bar has ends connected to two of the control arms and is pivotally connected to the suspension supports. Wheels are rotationally 10 connected to the knuckles.
