Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lifting columns restrict wheel access, necessitating multiple steps and equipment for wheel replacement, maintenance, and maintenance operations, posing safety risks.
Innovation Solution
A lifting column design with adjustable mast distance, integrated hydraulic cylinder, and additional mechanisms like side-shift, tilting, and locking, enabling easier access and safer operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional lifting columns are used with fixed mast distance, then lifting capability is provided, but wheel access is restricted
Solution Approach 1:
The mast distance is made adjustable rather than fixed, allowing the lifting column to adapt its configuration based on operational requirements. The masts can be positioned at different distances apart to either provide wheel access or maintain lifting capability, resolving the contradiction between ease of operation and device complexity.
2Ease of operation
If multiple equipment pieces are used for wheel maintenance, then wheel access is enabled, but safety risks increase
Solution Approach 1:
The lifting column is designed to combine multiple functions into a single integrated device. By making the mast distance adjustable, the same lifting column can both lift the vehicle and provide wheel access, eliminating the need for separate equipment like wheel dollies and reducing the number of operations that could compromise safety.
3Ease of operation
If wheel maintenance steps are performed with conventional lifting columns, then wheel access is achieved, but time consumption increases
Solution Approach 1:
The adjustable mast distance allows the lifting column to be quickly reconfigured from a closed lifting position to an open wheel-access position without requiring complete disassembly or additional equipment. This dynamic adjustment significantly reduces the time needed to transition between lifting and maintenance modes.
