Rotating Braking Device for Operating Table Base Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional operating tables risk tipping over when a carbon fiber bed board replaces part of the metal operation bed, necessitating a supporting leg that complicates adjustments and increases injury risks.
Innovation Solution
A metal-based braking device with rotatable supporting legs is mounted on the operating table base, extending the pivot point without expanding the table's length or width, eliminating the need for a supporting stand and ensuring stability during surgeries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a supporting leg is installed at the end or beneath the carbon fiber bed board to prevent tipping, then the stability of the operation bed is improved, but the ease of operation deteriorates due to complicated adjustments requiring removal of sterile sheets
Solution Approach 1:
The braking device extends the pivot point of the base loading in a rotational direction outside the operating table base, rather than extending the base length or width. This dimensional change allows the supporting legs to provide stability without occupying surgical space or complicating adjustments, as the rotation occurs in a different spatial dimension from the base structure
Solution Approach 2:
The braking device acts as an intermediary mechanism between the operating table base and the carbon fiber bed board. It provides the necessary support and stability through rotatable supporting legs that can be positioned as needed, without requiring direct modification to the bed board or complex installation procedures that would interfere with sterile operations
2Reliability
If a supporting stand is added to prevent tipping, then the reliability is improved, but the device complexity increases due to additional components and adjustment mechanisms
Solution Approach 1:
The braking device serves multiple functions: it provides stability support, allows rotational adjustment to extend the pivot point, and can be positioned flexibly around the operating table base. This multi-functionality eliminates the need for separate supporting stands while maintaining reliability, thereby reducing overall device complexity
Solution Approach 2:
The supporting legs are designed to be rotatable rather than fixed, allowing dynamic adjustment of the pivot point position. This dynamic capability provides reliability through adaptability to different surgical configurations without requiring complex fixed supporting structures
3Stability of the object's composition
If the pivot point is extended by adding a supporting stand, then the stability is improved, but the area occupied by the operating table base increases
Solution Approach 1:
Instead of extending the base area in the horizontal plane, the pivot point is extended through rotation in a different dimension. The braking device allows the supporting legs to rotate outside the base boundaries, effectively extending the pivot point without increasing the footprint area occupied by the operating table base

Function Achieved in This Case
The braking device prevents the operating table from tipping over during surgery, allows for smooth height and angle adjustments without removing sterile sheets, and reduces the risk of product damage, maintaining operational convenience and safety.
Implementation Method 1
The first pivoting portion pivotally connects to the second pivoting portion, so that each supporting leg rotates with respect to the operating table base

AI summary
The present invention provides a braking device for an operating table base, comprising at least two supporting legs, each supporting leg having a pivoting end and a supporting end distanced from the pivoting end. The operating table base supports an operation bed whose projected area covers the operating table base. The operating table base has a first pivoting portion corresponding to each supporting leg, and each supporting leg has a second pivoting portion at the pivoting end to correspond to the first pivoting portion of the operating table base. The first pivoting portion pivotally connects to the second pivoting portion, so that each supporting leg rotates with respect to the operating table base. The supporting ends of the supporting legs extend a supporting area of the operating table base.
