Simplest way to increase pressure in a container?

Click For Summary

Discussion Overview

The discussion centers around methods to increase the internal air pressure of a container for an invention, exploring various approaches while considering simplicity and cost-effectiveness. The scope includes conceptual ideas and practical mechanisms for pressure increase.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant suggests three primary methods to increase pressure: introducing more air, increasing temperature, or decreasing volume.
  • A proposed mechanism involves a lever system similar to a French press, designed to compress air within the container and maintain pressure using a ratchet.
  • Another participant requests additional details about the container's shape, initial and desired pressures, and the rate of pressure change needed.
  • Alternative suggestions include using a bicycle tire pump, a small CO2 cylinder, a cardboard tube balloon pump, or a hypodermic syringe without a needle.

Areas of Agreement / Disagreement

Participants generally agree that more information is needed to provide specific advice, and multiple approaches are suggested without consensus on the best method.

Contextual Notes

Limitations include the lack of detailed specifications regarding the container and the desired pressure parameters, which may affect the feasibility of proposed solutions.

I'm working on an invention which requires that I increase the internal air pressure of a container (while keeping it simple and cost-effective to produce).

I know my 3 options are to either: introduce more air into the container, increase the temperature, or decrease the volume.

One idea I had is trying to figure out a mechanism where the end user could simply press down on a lever, which would act similarly to a french-press (though the area being compressed would be air tight). There would be a ratchet to keep the lever from popping back up again due to pressure. Not sure if this would be the best approach.

Any ideas or suggestions on how to best tackle this problem?

Welcome to PF!

Your idea sounds good, but without highly detailed specifics of what you are trying to accomplish it is tough for us to answer with anything specific.
 
What shape is the container?
What is the initial absolute air pressure in the container?
What final absolute pressure do you require?
How quickly do you want the pressure to change?

A bicycle tyre pump?
Small C02 cylinder as used to inflate bike/car tyres?
Cardboard tube balloon pump?
Hypodermic syringe without needle?
