Pull-Out Table With Single Slide Rail and Steel Rope Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pull-out tables require two sliding rails, which increase costs and cause unsmooth pulling of the table board, while also requiring substantial manufacturing precision.
Innovation Solution
A pull-out table with a single slide rail is designed, using a steel rope, rope winding wheels, and slider seats to replace conventional bilateral slide rails, allowing smoother drawing and extension of the table board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two sliding rails are used on both sides of the table, then the table board can be pulled synchronously, but the cost increases and the pulling becomes unsmooth
Solution Approach 1:
The patent combines two separate sliding rail systems into a single sliding rail system. The first and second table boards are both connected to the same sliding rail through independent sliders, allowing them to move synchronously along the single rail. This merging reduces the number of components from two rails to one rail, simplifying the overall structure while maintaining the synchronous movement function.
Solution Approach 2:
The patent segments the connection between the table boards and the sliding rail by introducing independent sliders. Each table board has its own slider that engages with the single sliding rail, allowing individual control and movement while maintaining synchronous operation. This segmentation enables the system to achieve smooth pulling by distributing the movement control across multiple interaction points with the single rail.
2Reliability
If two sliding rails are used, then synchronous movement is achieved, but the manufacturing precision requirement increases
Solution Approach 1:
By merging two separate rail systems into one, the patent reduces the number of precision alignment requirements. Instead of needing to align two separate rails with high precision, the system only requires one sliding rail to be properly positioned. The independent sliders provide flexibility in accommodating minor variations while maintaining synchronous movement.
3Stability of the object's composition
If two sliding rails are used, then the table structure is stable, but the cost increases
Solution Approach 1:
The patent merges the support function of two rails into a single sliding rail by introducing a table frame structure. The sliding rail is mounted on the table frame, which provides additional structural support and stability. This allows the single rail system to bear the load of both table boards while maintaining structural integrity, eliminating the need for two separate rails.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The single slide rail design reduces costs, improves the smoothness of the table board's pulling and extension, and simplifies manufacturing, while allowing for efficient joining and separation of the table boards.
Implementation Method 1
The steel rope is synchronously wound around the rope winding wheel on each of the two ends of the inner frame

AI summary
A pull-out table with a single slide rail including a table frame, first and second table boards symmetrically disposed on the table frame, an extended table board disposed between the first and second table boards, and a sliding rail assembly, is provided. The sliding rail assembly including rope winding wheels is disposed on an inner frame on one side of the table frame along a length of the table frame. The rope winding wheel on one end of the inner frame is cooperatively linked to the rope winding wheel on the other end of the inner frame through a synchronously wound steel rope. The first and second table boards are respectively connected to an upper part and a lower part of the steel rope through respective slider seats. When one of the table boards is pulled, the other table board is driven to move in an opposite direction.
