Movable Table System for Compact XY Motion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional XY table systems are bulky and heavy due to the need for multiple moving tables underneath the top table, which complicates movement and increases size and mass, hindering high-speed control and precision.
Innovation Solution
A movable table system featuring a table, first and second actuators for independent movement in perpendicular directions, coupled with linear guides that directly connect the table to the actuators, and a support portion to manage reaction forces, allowing for a lightweight and simple structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple moving tables are arranged underneath the top table to enable movement in two perpendicular directions, then the table can achieve XY-direction movement capability, but the structure becomes bulky and heavy, increasing device complexity and mass
Solution Approach 1:
The patent merges the functions of multiple moving tables into a single integrated table structure. Instead of having separate x-axis and y-axis moving tables underneath the top table, the invention uses one table that can move in both X and Y directions through coordinated actuation, thereby reducing structural complexity while maintaining full XY movement capability
Solution Approach 2:
The single table is designed to perform multiple functions: it serves as both the x-axis moving table and the y-axis moving table simultaneously. The table is equipped with actuators that enable it to move independently in both perpendicular directions, making it a universal moving platform that eliminates the need for multiple specialized moving tables
2Adaptability or versatility
If multiple moving tables are arranged underneath the top table, then the table can achieve XY-direction movement capability, but the mass of the system increases, hindering high-speed control
Solution Approach 1:
By combining the mass of multiple moving tables into a single table structure, the total mass of the moving components is significantly reduced. The single table with integrated actuators weighs less than the equivalent system with separate x-axis and y-axis moving tables, enabling faster acceleration and deceleration for high-speed control applications
3Adaptability or versatility
If multiple moving tables are used to provide movement in perpendicular directions, then the table can achieve XY-direction movement capability, but the size of the system increases
Solution Approach 1:
The patent consolidates the spatial footprint of multiple moving tables into a single compact table structure. By eliminating the need for separate x-axis and y-axis moving tables, the overall volume occupied by the moving components is reduced, resulting in a more compact system design that maintains full XY movement capability
