Synchronizing Lifter Mechanism for Level Tabletop Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting tables with gas spring legs often cause the tabletop to incline when one side is raised or lowered, due to asynchronous operation of the gas springs, leading to user effort and instability.
Innovation Solution
A synchronizing lifter mechanism comprising a first and second inner fixed tube, a power transfer component, flexible traction components, a linear driver, and a locking mechanism, ensuring synchronized movement of both ends of the table by transferring power through flexible connections and a locking mechanism to prevent inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gas springs are used as table legs to support the tabletop, then the table height can be adjusted, but the gas springs cannot operate synchronously causing the tabletop to incline
Solution Approach 1:
The patent merges two independent gas spring systems into a synchronized lifting system by introducing a power transfer component that couples the motion of both gas springs. The first and second brackets, connected through the power transfer component, ensure that when one gas spring extends or compresses, the other follows simultaneously, maintaining tabletop levelness while preserving height adjustability
Solution Approach 2:
The power transfer component acts as an intermediary mechanism between the two gas springs. It receives motion from one bracket and transmits it to the other bracket, ensuring synchronized operation. This intermediary component resolves the contradiction by mediating the independent motions of the two gas springs into a coordinated synchronous movement
2Ease of operation
If separate control is applied to each gas spring, then individual adjustment is possible, but large pressing force is required and inclination occurs
Solution Approach 1:
The patent combines the control functions into a unified system where a single control input simultaneously actuates both gas springs through the power transfer mechanism. This merging of control eliminates the need for separate pressing operations on each end, reducing the total force required while maintaining the ability to adjust table height
3Stability of the object's composition
If synchronous operation is implemented, then tabletop levelness is maintained, but device complexity increases
Solution Approach 1:
The power transfer component serves multiple functions simultaneously: it transfers power between brackets, enforces synchronous motion, and maintains tabletop levelness. By designing a component that performs these multiple functions, the patent achieves synchronization without proportionally increasing overall system complexity
Solution Approach 2:
The patent employs a flexible traction component (such as a belt or chain) as the power transfer mechanism. This flexible element can accommodate the cylindrical motion of gas springs while transmitting force effectively, providing a simple and elegant solution that avoids complex rigid linkages or mechanical couplings

Function Achieved in This Case
Ensures the tabletop remains level during lifting by synchronizing the movement of both ends, reducing user effort and maintaining stability, while simplifying the structure and lowering costs.
Implementation Method 1
a first flexible traction component, wherein one end of the first flexible traction component is connected with the second inner fixed tube, the first flexible traction component is flexibly matched with one end of the second bracket, one end of the first bracket and the other end of the first bracket
Implementation Method 2
a linear driver, wherein a power output portion of the linear driver is connected with one of the first flexible traction component, the second flexible traction component, the first bracket and the second bracket
Implementation Method 3
a locking mechanism, wherein the locking mechanism is matched with the power output portion of the linear driver so as to limit the displacement of the output portion of the linear driver
Data Source
AI summary
A synchronizing lifter and a lifting table are disclosed that can ensure components supported on the synchronizing lifter cannot be in an inclined state. This has advantages in that by releasing the locking of one of power output portions of a linear driver, a first flexible traction component, a second flexible traction component, a first bracket and a second bracket through a locking mechanism, the driver works and a flexible connection component connected to the output end of the driver can move. The power is transferred to a corresponding bracket that drives a power transfer component to move up or down. The power transfer component drives the other bracket to move up or down, and another bracket drives the other flexible traction component to move. One driver drives the two ends of a synchronizing mechanism to move up and down, so that the structure is simple and costs are kept low.
