Solution Overview
Problem
Existing operating table systems face challenges with sealing to prevent water and particles from entering critical components, and the emergency mode control is unstable due to software reliance, while the column guide system experiences stick-slip phenomena and high manufacturing costs.
Innovation Solution
The implementation of a sealing system using flexible bellows and gaskets to prevent ingress of unwanted substances, and a hardware-based control module for stable emergency mode operation, along with a screw-and-nut transmission and guide slider system for precise height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a sliding guide system is used for the column guide, then the structure is simple, but it causes stick-slip phenomenon and high wear leading to gaps and lock-in-place issues
Solution Approach 1:
The patent replaces the traditional sliding mechanical guide system with a rolling guide system. The rolling guide comprises a guide rail and a roller that rolls along the guide rail, substituting sliding friction with rolling friction. This eliminates the stick-slip phenomenon and reduces wear between the top column and bottom column, ensuring smooth and reliable column movement throughout the entire height range.
2Ease of operation
If a lifting pipe with groove is used to prevent rotary movement, then the top column can be driven vertically, but the manufacturing cost is high
Solution Approach 1:
The patent replaces the complex lifting pipe with groove structure with a screw-and-nut transmission system. The screw rod is driven by a motor to rotate, and the nut converts this rotational motion into vertical linear motion of the top column. This substitution simplifies the manufacturing process while maintaining precise control over vertical movement and eliminating the need for expensive groove-shaped lifting pipes.
3Adaptability or versatility
If software-based control is used for normal operation, then the control is flexible, but the emergency mode control is unstable
Solution Approach 1:
The patent segments the control system into two independent parts: a software-based control module for normal operation that provides flexibility, and a dedicated hardware control module for emergency mode that ensures stability. The hardware module includes physical switches and relays that directly control the motor during emergencies, bypassing the software layer. This segmentation allows each control mode to use the most appropriate control method for its specific requirements.
4Reliability
If a rolling guide system is used, then wear is reduced and friction is low, but it is normally suitable for horizontal position only
Solution Approach 1:
The patent adapts the rolling guide system for vertical application by changing the orientation parameter of the guide rail and roller assembly. The guide rail is positioned vertically along the bottom column, and the roller is configured to roll along this vertical guide rail, enabling the top column to move up and down smoothly. This parameter change allows the rolling guide system to maintain its wear-resistant and low-friction advantages while being applicable to vertical positions in the operating table.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The sealing system effectively prevents contamination, and the hardware control module ensures reliable emergency mode operation, while the guide slider system enhances stability and reduces manufacturing costs by minimizing wear and friction.
Implementation Method 1
a screw-and-nut transmission (330, 350) for moving the top column (320) in the vertical direction
Implementation Method 2
The guide sliders (515) are fitted on the guide rails (514) in a positive-locking manner... the guide slider system enhances stability and reduces manufacturing costs by minimizing wear and friction
Implementation Method 3
proper sealing devices are required to prevent the undesired objects such as water or particles from intruding the equipment
