Single-Piece Stabilizer Bracket Eliminating Weld Stress Risers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stabilizer brackets for sway bars in vehicle suspension systems are prone to weakening at weld seams, leading to potential fracturing, warping, or loosening due to stress risers and inconsistent welding, which can result in uneven securing forces and instability.
Innovation Solution
A single-piece stabilizer bracket is designed with a bar clamp integrally formed with fastener mounts from a single piece of material, eliminating weld seams and incorporating a curved strap and support walls for enhanced strength and bracing, thereby preventing stress risers and ensuring consistent securing forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate fastener tubes are welded to the bar clamp, then the stabilizer bracket can be assembled from multiple components, but weld seams create stress risers that weaken the structure and lead to fracturing
Solution Approach 1:
The patent merges the bar clamp and fastener tubes into a single integrally formed stabilizer bracket. The bracket is formed as one continuous piece of metal stock, eliminating the need for separate fastener tube components and their associated weld seams. This integration removes the stress risers that would otherwise be created by weld joints, thereby improving structural reliability while maintaining manufacturability through integral forming processes.
2Device complexity
If weld joints are used to attach fastener tubes, then the assembly can be constructed from separate parts, but the weld joints create fatigue zones susceptible to weakening under temperature and pressure
Solution Approach 1:
The patent combines multiple components into a single integrally formed bracket structure. The fastener mounts are formed as integral portions of the bar clamp, eliminating weld joints entirely. This merger removes the fatigue zones that would otherwise exist at weld locations, significantly improving the structure's resistance to fatigue from temperature and pressure cycling while simplifying the overall device complexity.
3Productivity
If the bar clamp is formed through stamping, then the component can be manufactured efficiently, but longitudinal edges may bend or warp during operation causing uneven securing forces
Solution Approach 1:
The patent incorporates curved or folded portions in the bar clamp structure, particularly in the longitudinal edges. These curved sections provide inherent structural reinforcement that prevents bending and warping during operation. The curvature distributes stresses more evenly throughout the material, maintaining edge stability and ensuring uniform securing forces on the sway bar while still allowing for efficient stamping or forming processes.
