Folded Metal Post Lift Column for Precise Guide Track Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromechanical post lifts face manufacturing challenges such as complex and laborious construction processes due to manual welding of profiled elements, difficulty in accessing welding points, uneven cooling leading to deformation, high dimensional tolerances, and the need for large storage spaces.
Innovation Solution
The lift employs a single, folded slab-shaped metal element to create the post and rolling tracks, eliminating manual welding and enabling automated manufacturing, reducing deformation risks, and achieving precise dimensional tolerances of ±1 mm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If profiled elements are welded to the tubular body to create rolling tracks, then the load-bearing capacity and structural strength are improved, but the manufacturing complexity and labor requirements increase significantly
Solution Approach 1:
The patent merges the tubular body and profiled elements into a single integrated component. The rolling tracks are formed directly from the tubular body through internal rib structures, eliminating the need for separate profiled elements and welding operations. This integration maintains structural strength while dramatically simplifying manufacturing.
Solution Approach 2:
The patent extracts the welding operation from the manufacturing process entirely. By forming the rolling tracks as integral parts of the tubular body through cold-forming or stamping operations, the harmful welding process is removed, eliminating associated problems like access difficulties, deformation, and high tolerances.
2Ease of manufacture
If manual welding is used to attach profiled elements, then the rolling tracks can be constructed, but the production time and labor costs increase
Solution Approach 1:
The patent replaces the manual welding mechanical system with automated cold-forming or stamping operations. The rolling tracks are formed by mechanically shaping the tubular body using dies and presses, which can be automated and performed much faster than manual welding while maintaining constructibility.
3Ease of manufacture
If welding is used to join profiled elements, then the rolling tracks are formed, but dimensional precision and straightness deteriorate due to heat deformation
Solution Approach 1:
The patent converts the harmful thermal effects of welding into beneficial cold-forming processes. By using mechanical shaping operations instead of thermal welding, the process eliminates heat-induced deformation while maintaining the ability to form complex rolling track geometries with high precision and straightness.
