Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotic operating tables have limited horizontal movement range and poor freedom of movement, making it difficult for medical personnel to position patients correctly and maintain sufficient space during surgeries.
Innovation Solution
A robotic operating table equipped with a multi-jointed robotic arm, operation devices, and a controller that allows for large-range movement and registration of positions, enabling the table to be moved to previously set positions with ease.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the movable top panel is made slidable on a fixed base, then the structure is simple and stable, but the range of horizontal movement is small and freedom of movement is poor
Solution Approach 1:
The patent replaces the traditional mechanical sliding mechanism with a robotic arm system that uses motors and controllers to achieve table positioning. This substitution enables large-range movement in multiple directions while maintaining structural stability through the robotic arm's controlled motion rather than mechanical slides.
Solution Approach 2:
The patent transforms the static fixed base structure into a dynamic robotic arm system that can adaptively position the table. The robotic arm provides dynamic movement capabilities in multiple directions (horizontal, vertical, rotational) while the base remains stationary, resolving the contradiction between movement range and structural simplicity.
2Adaptability or versatility
If the movable top panel has limited movement range, then the structure remains compact, but it is difficult to move the table to various positions desired by medical personnel
Solution Approach 1:
The patent extends the movement capability from a single horizontal plane to multiple dimensions by implementing a robotic arm system that provides horizontal movement, vertical movement, and rotational movement. This multi-dimensional positioning capability allows the table to reach various positions without requiring a larger physical footprint.
3Ease of operation
If manual operation is used to move the table, then the operation is simple, but it is difficult to move the table back to a previous position
Solution Approach 1:
The patent implements a registration function that stores the table's position and robotic arm posture in advance. When repositioning is needed, the system retrieves the stored data and automatically restores the table to the previous position, eliminating the time-consuming manual adjustment process while maintaining simple operation through button presses.
Solution Approach 2:
The patent uses sensors and encoders to detect the table's position and robotic arm's posture, providing feedback to the control system. This feedback mechanism enables precise positioning and accurate restoration to previous positions, making the operation both simple and time-efficient.
