Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The difficulty in mounting suspension upper swing arm and shock absorber components on automobile chassis due to precision deviations in mounting structures, leading to longer installation times and higher costs.
Innovation Solution
Integration of suspension upper swing arm and shock absorber mounting portions directly into the longitudinal beam assembly, eliminating separate mounting errors and simplifying the manufacturing process, resulting in improved position accuracy and reduced manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mounting structures are reserved separately on the chassis, then the chassis can support suspension and shock absorber components, but mounting precision is reduced due to separate manufacturing and assembly errors
Solution Approach 1:
The patent integrates the mounting structures for suspension upper swing arm and shock absorber directly into the longitudinal beam as integral components. This merging eliminates separate mounting structures and their associated assembly errors, achieving higher mounting precision while reducing overall structural complexity through consolidation.
2Productivity
If multiple separate mounting structures are manufactured and assembled, then various components can be mounted, but manufacturing time and installation time increase
Solution Approach 1:
By combining multiple mounting structures into the longitudinal beam as integral components, the patent eliminates separate manufacturing and assembly steps. This reduces both manufacturing time for producing multiple parts and installation time for assembling them, thereby improving overall productivity.
Solution Approach 2:
The mounting structures are pre-integrated into the longitudinal beam during its manufacturing process, preparing the mounting interfaces in advance. This preliminary integration eliminates the need for separate field assembly operations, reducing installation time and improving productivity.
3Manufacturing precision
If separate mounting structures are welded to the longitudinal beam, then components can be mounted, but welding errors affect position precision and increase manufacturing cost
Solution Approach 1:
The patent integrates mounting structures directly into the longitudinal beam as integral components rather than welding separate parts. This eliminates welding operations and associated welding errors that compromise position precision, while simplifying the manufacturing process by reducing the number of discrete components and assembly steps.
