Synchronous Adjusting Mechanism for Linear Lifting Column Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric linear motion elements in lifting columns face issues with insufficient pushing force when centered, displacement errors leading to synchronization problems, and pendulum effects causing instability when symmetrically disposed, affecting lifting speed and stability.
Innovation Solution
A synchronous adjusting mechanism with multiple force-bearing ends separated by a rotating radius ensures that motion elements move synchronously, reducing pendulum effects and increasing pushing force by coordinating forces to achieve a resultant force direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If two or more electric linear motion elements are disposed on both sides of the lifting column to increase pushing force, then the pushing force is improved, but displacement errors occur and pendulum effects are generated causing the lifting column to swing
Solution Approach 1:
A synchronous adjusting mechanism is introduced as an intermediary component between the electric linear motion elements and the lifting column. This mechanism includes a synchronous adjusting shaft with adjusting arms that connect to the motion elements, mediating their forces and coordinating their movements to maintain synchronization and eliminate pendulum effects
Solution Approach 2:
The synchronous adjusting mechanism merges the forces from multiple electric linear motion elements through a common synchronous adjusting shaft. The adjusting arms connect each motion element to the shaft, combining their individual forces into a coordinated unified action that prevents displacement errors and maintains lifting column stability
2Device complexity
If electric linear motion elements are disposed on one side of the lifting column, then the device complexity is reduced, but the pushing force becomes insufficient and lifting speed decreases
Solution Approach 1:
The lifting system is segmented into multiple independent electric linear motion elements distributed on both sides of the lifting column. Each element operates independently but is coordinated through the synchronous adjusting mechanism, allowing increased pushing force and lifting speed while maintaining manageable complexity through modular segmentation
3Reliability
If displacement errors occur in electric linear motion elements, then synchronization is lost and pendulum effects are generated, but the invention's synchronous adjusting mechanism restores synchronization by coordinating the motion elements
Solution Approach 1:
The synchronous adjusting mechanism provides mechanical feedback coordination between motion elements. The adjusting arms and synchronous adjusting shaft create a feedback system that automatically compensates for displacement errors, ensuring that if one element deviates, the mechanism adjusts to restore synchronization and eliminate pendulum effects

AI summary
A linear lifting device including a lifting column, a synchronous adjusting mechanism, a first motion element and a second motion element is provided. The lifting column has a fixed end and a movable end. The synchronous adjusting mechanism, disposed on the movable end, has a first force-bearing end and a second force-bearing end, which are respectively separated from the center of the synchronous adjusting mechanism by a rotating radius and remain at a synchronous state. The first and second elements respectively connect the first and second force-bearing ends for generating a first force to push the first force-bearing end to move in a first force direction and generating a second force to push the second force-bearing end to move in a second force direction, such that the movable end can move with respect to the fixed end in a resultant force direction of the first and second force directions.
