Modular Positioning Device for Heavy Components in Constrained Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning devices for heavy components are either not compact enough to fit in small spaces or lack the necessary degrees of freedom for precise positioning, particularly in areas with limited access, as they often only allow movement along two axes and do not accommodate rotational movements.
Innovation Solution
A modular positioning device with five modules arranged in parallel planes, allowing for independent displacement along three axes and rotational movements, enabling precise positioning of heavy components in a compact and flexible manner by utilizing movable couplings and threaded spindles connected to rotary drives for motorized adjustments.

Engineering Contradiction Analysis
1Adaptability or versatility
If hexapods are used to position heavy components, then the position can be adjusted in six degrees of freedom, but the device is not compact and requires large installation space
Solution Approach 1:
The positioning device is divided into multiple modular units (base unit, intermediate units, top unit) that can be stacked vertically. Each unit contains specific positioning mechanisms (e.g., first positioning mechanism for x-y plane movement, second positioning mechanism for z-axis movement), allowing the system to achieve six-degree-of-freedom positioning while maintaining a compact vertical footprint.
Solution Approach 2:
The patent transitions from a horizontal expansion layout (like traditional hexapods) to a vertical stacking layout. By arranging positioning mechanisms along the z-axis direction and utilizing vertical space, the device achieves full six-degree-of-freedom positioning capability while significantly reducing the horizontal installation footprint.
2Device complexity
If positioning tables are used to move components along two axes, then the structure is simple, but rotational movements are not allowed
Solution Approach 1:
The patent combines multiple positioning functions into a single integrated modular unit. Each modular unit incorporates both translational positioning mechanisms (for moving along axes) and rotational positioning mechanisms (for rotating components). This merging of functions allows the device to maintain relative structural simplicity while achieving comprehensive six-degree-of-freedom positioning including rotational movements.
3Volume of moving object
If compact positioning devices are designed to fit small spaces, then the installation space is reduced, but the load-bearing capacity for heavy components is limited
Solution Approach 1:
The patent employs support structures and positioning mechanisms designed to counterbalance heavy loads. The modular units include robust support elements (such as support columns, bearing structures) that can withstand and distribute the weight of heavy accelerator components. The vertical stacking configuration allows load paths to be optimized through the z-axis, with each module contributing to the overall load-bearing capacity while maintaining compact horizontal dimensions.
