Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current suspension alignment procedures for motor vehicles require frequent adjustments of camber and caster angles, which can be time-consuming and costly, often necessitating complex adjustments or modifications to achieve optimal vehicle performance and reduce tire wear.
Innovation Solution
A suspension alignment system featuring slotted alignment bushings with interchangeable inserts of varying offset positions, allowing for quick selection and placement to achieve nominal caster and camber angles without the need for complex machinery or modifications to the vehicle frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional suspension alignment procedures are used, then alignment adjustments can be made, but the process is time-consuming and requires complex adjustments or modifications to the vehicle frame
Solution Approach 1:
The alignment system is segmented into multiple interchangeable inserts, each with a different locating hole position. Instead of modifying the entire bushing or frame, only the insert needs to be changed to achieve different alignment settings. This segmentation allows quick swapping of inserts to adjust camber and caster angles without complex procedures.
Solution Approach 2:
The invention changes the positional parameter of the locating hole within the insert to achieve different alignment angles. By varying the location of the hole in different inserts, the system provides multiple fixed alignment positions, enabling adjustment of camber and caster angles without complex mechanical modifications to the vehicle frame or suspension assembly.
2Manufacturing precision
If multiple alignment positions are provided, then accurate alignment can be achieved, but the bushing structure becomes more complex
Solution Approach 1:
The complex functionality of providing multiple alignment positions is segmented into separate interchangeable inserts rather than incorporating all positions into a single complex bushing structure. Each insert is a simple component with a specific locating hole position, and the set of inserts collectively provides the full range of alignment options. This segmentation maintains individual component simplicity while achieving system-level precision.
Solution Approach 2:
A single bushing structure is designed to be universal by accommodating multiple different inserts. The bushing itself remains relatively simple, but it gains multi-functionality through the interchangeable insert system, allowing it to provide multiple precise alignment positions without requiring the bushing structure itself to become complex.
3Reliability
If frequent alignment adjustments are made, then optimal vehicle performance is maintained, but time and cost increase
Solution Approach 1:
Multiple inserts with different locating hole positions are prepared in advance, each corresponding to predetermined alignment positions. When alignment adjustment is needed, the technician can quickly select and install the appropriate pre-prepared insert without performing complex measurements or adjustments during the service encounter. This preliminary preparation of multiple insert options significantly reduces the time required for alignment adjustments while maintaining the ability to achieve optimal vehicle performance.

AI summary
An alignment assembly for a motor vehicle includes a first bushing with a slot, the first bushing being configured to be positioned and secured to an end of a first link of a wishbone suspension assembly, and an insert that fits within the slot, the insert having a locating hole that positions a bolt within the slot for nominal caster and camber angles.
