Air Bellow Device for Vehicle Lifting Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air bellow devices for vehicle lifting frames are time-consuming and expensive to replace due to complex fixation methods, which disrupt workflow and business operations when worn out, especially when dealing with cars of low ground clearance.
Innovation Solution
The air bellow device features a sandwich construction connecting plate with a stabilizing arm and multiple air bellows connected via flanges, allowing for easy replacement of individual bellows and secure attachment to the vehicle lifting frame using form-fitting elements and a T-shaped stabilizing arm for enhanced stability and reduced installation time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air bellows are secured with glue in combination with screws, then the fixation is strong and reliable, but the replacement process becomes time-consuming and expensive
Solution Approach 1:
The air bellow device is divided into separable components: the air bellow itself and the connecting plates with fixation elements. This segmentation allows the air bellow to be replaced independently without replacing the entire assembly, reducing replacement time while maintaining reliable fixation through the reusable connecting plates
Solution Approach 2:
The connecting plates with fixation elements are pre-assembled and prepared before the air bellow needs replacement. The first connecting plate is already attached to the vehicle lifting frame, and the second connecting plate is prepared with the air bellow, allowing for quick installation without on-site assembly complexity
2Reliability
If complex and multiple fixation elements are used to secure air bellows, then the connection is secure, but the replacement process becomes time-consuming and expensive
Solution Approach 1:
Multiple fixation functions are merged into integrated connecting plates. The first connecting plate combines the first upper connecting surface, first lower connecting surface, and first connecting elements into a single component that attaches to the vehicle lifting frame. The second connecting plate similarly integrates the second upper connecting surface, second lower connecting surface, and second connecting elements, simplifying the overall fixation system while maintaining security
3Length of moving object
If the vehicle lifting frame is raised to a high position, then it can lift cars to the desired height, but cars with low ground clearance cannot easily position over the frame
Solution Approach 1:
The air bellow device provides dynamic height adjustment capability. The air bellow can be inflated to raise the second connecting plate and attached components to the desired lifting height, or deflated to lower them for easy positioning of low ground clearance vehicles. This dynamic adjustment allows the system to adapt to different operational requirements
