Table Circulation Guidance Device with Sliders and Carriages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing table circulation guide devices face challenges in smoothly transitioning between straight and curved rail sections, leading to increased resistance, impact, and instability due to unbalanced loads and differences in rail height, which affects the accuracy and reliability of operations like machining and assembly.
Innovation Solution
The design incorporates a circuit with pairs of straight and curved rails where the table travels on straight rails via sliders for working areas and on curved rails via carriages for non-working areas, with offset rail ends and tapered sections to minimize deviation and distribute load evenly, using sliders on both sides of the table for stability and a movable-magnet-type linear motor for smooth transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dolly is used to move a table, then the table can be moved, but the dolly occupies additional space and may trip attendees
Solution Approach 1:
The table base itself is converted into a mobile platform by integrating rollers directly onto the base structure, eliminating the need for a separate dolly. This merging of functions allows the table to be moved without requiring additional space-occupying equipment.
Solution Approach 2:
The mobile function is extracted from the table top and placed into the base structure. By positioning the rollers at the bottom of the base, the mobility feature is separated from the visible table structure, preventing tripping hazards while maintaining ease of movement.
2Ease of operation
If the table base is made lighter for easier movement, then mobility improves, but the stability and weight-bearing capacity decrease
Solution Approach 1:
Manual lifting and moving of the entire table is replaced by a mechanical rolling system. The rollers provide mechanical assistance for movement, allowing the table to be easily relocated without requiring reduction of the base weight, thus maintaining stability while improving mobility.
3Adaptability or versatility
If the table configuration is changed frequently for different events, then versatility improves, but setup time and complexity increase
Solution Approach 1:
The table system transitions from a static configuration to a dynamic one where the base can be easily repositioned and reconfigured. The mobile base allows tables to be quickly moved and rearranged between events, enabling flexible configuration changes without time-consuming manual handling.
Solution Approach 2:
The table system is divided into modular components with mobile bases that can be independently positioned. This segmentation allows individual tables or groups of tables to be moved and reconfigured separately, reducing the overall setup time for different event configurations.

AI summary
This table circulation guide device includes sliders (8) and carriage (6) attached to a table (1). In a working area (28), the table is guided by the sliders (8) straddling straight track rails (2). In a non-working area (29), the table (1) is guided by the carriages (6) traveling on a curved track rail (3). An endless circulation circuit (30) is formed by the straight track rails (2) and the curved track rail (3). In the working area (28) of the circuit (30), the table (1) travels via the sliders (8) straddling the straight track rails (2). In the non-working area (29) of the circuit (30), the table (1) travels via the carriages (6) located between the sliders (8).
