Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operating tables have fixed structures, restricting their movement and rotation, making it difficult to adjust their location and angle, which limits their versatility and efficiency in accommodating complex machining operations.
Innovation Solution
An operating table with multiple degrees of freedom, equipped with an elevating mechanism, a moving mechanism on a horizontal plane, and a multiple angle rotation mechanism, allowing for independent or cooperative movement in the X and Y directions, as well as rotational adjustments, facilitated by a leadscrew and nut structure, universal joint device, and locking mechanism, enabling manual, automatic, or digital control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operating table uses a fixed structure, then the structure is simple and stable, but the operating table cannot move or rotate to adjust location and angle
Solution Approach 1:
The operating table is divided into multiple independent modules: a pedestal, a moving mechanism with X and Y direction components, and a rotating mechanism. Each module can move or rotate independently, allowing the table to achieve complex positioning through combination of simple modular actions.
Solution Approach 2:
The operating table transitions from a fixed structure to a dynamic structure with multiple degrees of freedom. The table can move horizontally in X and Y directions, rotate around vertical and horizontal axes, and tilt, enabling adaptive positioning for different machining operations.
2Ease of operation
If the whole pedestal is moved to change location, then the operating table location changes, but the heavy pedestal is inconvenient to move and requires large space
Solution Approach 1:
The moving mechanism is segmented into X-direction and Y-direction components that can move independently. This allows the operating table to be repositioned by activating only the necessary movement component rather than moving the entire heavy pedestal, reducing the effort and space required for relocation.
3Adaptability or versatility
If the operating table surface is tilted to meet machining needs, then the viewing angle and light are improved, but the structure becomes more complex
Solution Approach 1:
The rotating mechanism combines multiple rotation functions into a single integrated system. The table can rotate around a vertical axis and tilt around a horizontal axis simultaneously, achieving multi-angle positioning through one unified mechanism rather than separate systems for each rotation.

AI summary
Disclosed is an operating table with multiple degrees of freedom which is capable of moving and rotating in various directions. The operating table comprises an elevating mechanism, a moving mechanism on a horizontal plane and a multiple angle rotation mechanism, with the elevating mechanism and the moving mechanism adopting a leadscrew structure, the multiple angle rotation mechanism comprising a universal joint device (7) and a locking mechanism. The moving mechanism can drive the operating table (6) to move on a horizontal plane and ensure the operating table (6) can reach any location within a valid region on a horizontal plane, the moving mechanisms in the X and Y directions can operate separately as well as cooperatively, and the multiple angle rotation mechanism drives the surface of the operating table to tilt. These mechanisms work in combination to accomplish the location change of the operating table.
