Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual object lifting requires high labor intensity, is dangerous, and inefficient, with existing lifters occupying large space and requiring auxiliary ascent devices for high elevations, limiting their application scope.
Innovation Solution
A lifter with a support base, elevating stand assembly, elevating-drive mechanism, turning-drive mechanism, and bracket mechanism, featuring foldable and retractable design, adjustable height, and inclinable bracket for adaptable material positioning, reducing labor and space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bracket portion and support portion are fixed perpendicular to each other, then the structure is simple and stable, but the lifter occupies large space when idle and has limited application scope
Solution Approach 1:
The support base is designed to be rotatable relative to the carrier bracket, transforming the fixed perpendicular structure into a dynamic adjustable configuration. This allows the support base to rotate to different angles, enabling the lifter to adapt to different working conditions and reduce the space occupied when idle, thereby improving both adaptability and space efficiency
2Productivity
If manual lifting is used, then no additional equipment is needed, but labor intensity is high and working efficiency is low
Solution Approach 1:
The patent replaces manual mechanical lifting with a motor-driven elevating mechanism. The motor drives the carrier bracket to move vertically along the guide rail, automatically completing the lifting operation. This substitution of manual labor with automated mechanical systems significantly improves working efficiency and reduces labor intensity
3Adaptability or versatility
If fixed height lifter is used, then the structure is simple, but the application scope is limited
Solution Approach 1:
The patent incorporates an adjustable height mechanism where the carrier bracket can move vertically along the guide rail under motor drive. This dynamic height adjustment capability allows the lifter to adapt to different lifting heights and application scenarios, expanding the application scope while maintaining reasonable structural complexity through modular design
