Universal Shock Absorber Indexing Device for Vehicle Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing suspension system arrangement for motor vehicles, which includes multiple indexing members for shock absorber positioning, leads to increased spare part references, management complexity, and higher production costs due to the need for distinct parts for front and rear indexing, resulting in assembly errors.
Innovation Solution
An indexing device with a first and second indexing member, both capable of ensuring front and rear indexing of the shock absorber relative to the support, featuring symmetrical wings with inclined edges and a fixing base, allowing for integral mounting and simplified assembly by guiding the shock absorber into position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If differentiated indexing members are used for front and rear shock absorber positioning, then adequate positioning precision is achieved, but the number of spare part references increases and management complexity increases
Solution Approach 1:
The indexing member is designed with a symmetrical wing structure that allows it to perform both front indexing and rear indexing functions. The symmetrical geometry enables the same component to be used in opposite orientations, making one type of indexing member universal for both front and rear shock absorber positioning tasks, thereby reducing the number of different part references needed.
2Manufacturing precision
If differentiated indexing members are used for front and rear shock absorber positioning, then adequate positioning precision is achieved, but production cost increases
Solution Approach 1:
By designing a universal indexing member with symmetrical wings that can serve both front and rear positioning needs, the manufacturing process is simplified. Instead of producing multiple different types of indexing members with varying geometries, the same standardized component is manufactured in bulk, reducing tooling costs, setup time, and overall production expenses while maintaining positioning precision.
3Manufacturing precision
If differentiated indexing members are used for front and rear shock absorber positioning, then adequate positioning precision is achieved, but assembly error risk increases
Solution Approach 1:
The symmetrical design of the indexing member eliminates the need for assembly workers to distinguish between front and rear specific components. Since both indexing members look identical and can be used in either orientation, the risk of assembling the wrong type of indexing member is eliminated, thereby improving assembly reliability while maintaining positioning precision.
4Manufacturing precision
If multiple indexing member types are used, then specific positioning requirements are met, but inventory management complexity increases
Solution Approach 1:
By consolidating front and rear indexing members into a single universal type with symmetrical wings, the spare parts inventory is simplified. Instead of maintaining separate stock levels for different front and rear indexing member types, only one type needs to be inventoried and managed, reducing inventory complexity while ensuring positioning accuracy is maintained.
