Mobile Operating Table Speed Control Using Single-Element Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile operating tables require complex and time-consuming procedures to switch between different drive speeds, especially in tight operating room spaces, and often have cluttered control panels due to multiple operating elements for speed changes and other functions.
Innovation Solution
A method and device that allow for simple activation of a drive unit with different speed levels using a single control element, where the first drive speed is activated by a single operation and the second drive speed by double-clicking or a specific interruption pattern, enabling convenient speed switching without deactivating the drive unit, and providing an intuitive operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate operating element is provided for each speed level, then speed switching is simple, but the control panel becomes confusing and complex
Solution Approach 1:
A single operating element is designed to perform multiple functions: it can activate the drive unit at first drive speed with a first actuation, switch to second drive speed with a second actuation, and deactivate the drive unit with a third actuation. This multi-functional design eliminates the need for separate buttons for each speed level and deactivation, simplifying the control panel while maintaining ease of operation.
2Loss of time
If menu navigation is used for speed switching, then control is precise, but the process is time-consuming
Solution Approach 1:
The system is designed so that the operating element is pre-configured with different functions that are activated based on the actuation pattern. The control unit is pre-programmed to recognize first, second, and third actuations and automatically execute the corresponding speed changes or deactivation without requiring menu navigation. This eliminates the time-consuming process of accessing menus while maintaining precise control.
3Productivity
If the drive unit is deactivated for speed switching, then speed change is possible, but workflow is disrupted
Solution Approach 1:
The system dynamically changes the drive speed by transitioning between different speed levels (first drive speed and second drive speed) without deactivating the drive unit. The control unit receives actuation signals and adjusts the motor speed accordingly, allowing continuous movement while changing speed. This dynamic speed adjustment maintains workflow continuity while achieving the desired speed change.

AI summary
The invention relates to a method and a device for operating a mobile operating table (30), which comprises a patient support surface (31), an operating table column (40), an operating table column foot (41) and a drive unit (48), wherein the operating table (30) comprises rollers (50 to 56) and a drive unit (48) for displacing the operating table (30). The drive unit (48) is activated with a first drive velocity in the case of a single actuation of the operating element (28) and with a second drive velocity in the case of a double actuation of the operating element (28). The first drive velocity is preferably less than the second drive velocity.
