Wireless Remote Control for Vacuum Pump Stand Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum pumping stations for rotary evaporators pose health risks to laboratory personnel due to the need for direct operation and potential loss of control when batteries run out, especially when processing hazardous volatile liquid mixtures.
Innovation Solution
A pumping station with a remote control unit in wireless connection to the control device, featuring a console with a contact system for battery charging and a touchscreen for monitoring and controlling process parameters, allowing operation directly or from a distance while ensuring continuous power supply and safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pumping station is operated directly with the operating unit on the console, then the control connection is reliable, but the laboratory personnel are exposed to health hazards from hazardous volatile liquid mixtures
Solution Approach 1:
The patent introduces a wireless remote control unit as an intermediary between the operator and the pumping station. This remote control unit communicates wirelessly with the control device, allowing operators to control the pumping station from outside the fume hood without direct contact with hazardous volatile liquid mixtures, thus resolving the contradiction between control reliability and health safety
2Object-affected harmful factors
If the pumping station is operated wirelessly from a distance using the remote control unit, then the exposure to hazards is reduced, but the control connection may be lost when the battery runs out
Solution Approach 1:
The patent implements a docking station with a contact system that automatically charges the battery of the remote control unit when it is placed on the docking station. This beforehand cushioning ensures that the battery is continuously recharged, preventing control connection loss due to battery depletion and maintaining reliable wireless operation
3Ease of operation
If the remote control unit is equipped with a touchscreen for displaying process parameters, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent uses a touchscreen display on the remote control unit that visually copies and displays the process parameters and control interface. This allows operators to interact with the pumping station through an intuitive graphical interface similar to what would be seen on a computer, significantly improving ease of operation while the complexity is managed through software implementation

AI summary
The invention relates to a vacuum pump stand (1) for generating and regulating the vacuum intended for a rotary vaporizer, comprising a control device having a control connection to a control unit (4) having at least one control element (3, 6). The pump stand (1) according to the invention is characterized in that the control unit (4) is designed as a remote control unit having a wireless control connection to the control device of the pump stand. Laboratory personnel can thus observe the rotary evaporator and the associated pump stand (1) according to the invention through the divider of an extractor, in order to be able to modify and readjust the process parameters at the remote control panel as needed. Because the remote control unit (4) has a wireless control connection to the control device of the pump stand (1), the extractor no longer needs to be opened, even momentarily. Rather, the pump stand (1) can be operated from a sufficient distance outside the extractor without the laboratory personnel needing to be exposed to special hazards (see FIG.).
