Travel Toothbrush Project:

[Nav29]

I have made this travel toothbrush and toothpaste tube product. The neck is replaceable after use and the toothpaste tube is refillable. Please could you give me soem feedback - thank you!

Why did you bother? for the time and effort its taken you to do all that, a travel toothbrush can be obtained online for less than a pound.

WHat you have made is going to raise the suspicions of most border control/security agents.

Solution looking for a problem?

When refilling the tooth paste tube the air that is displaced by the toothpaste has to have a way out of the tube,

If the nozzle of the Oral B toothpaste tube is an air tight fit into the toothpaste tube ( of the brush ) then the air cannot get out of the tube.

Great school project. Maybe add some space for dental floss and toothpicks?

You’re forgetting mouthwash.

Can you make the toothbrush vibrate?

 

[mattylad]

ooooh, now its becoming multi use

 

[Nav29]

Thank you for all the feedback.
mattylad: I didn't make it for personal use, it is a school project and I have to get feedback from stakeholders.
bernardgreen: For refilling- the user has to push the air out before they refill it so the paste can get in.
plastic_peanut: it can't vibrate.

As others have said - you have a solution looking for a problem. Hope it is a design project at school.

Your design with the toothbrush bristle exposed at all times means the bristles will be damaged when packed in luggage. If packed away wet will get the surrounding fabrics wet, possibly marked (have you tried to remove toothpaste stains from clothes? - very difficult). 3ml of toothpaste is the same size as several airlines hand out to long distance flyers - good for about 2 uses...

All you really need is a simple box on the lines of a spectacles case to take a full size toothbrush and a small tube of toothpaste that when closed is watertight and will not break easily.

Grams count when you're flying. My 'wash bag' when travelling abroad is a Sandwich bag - containing a basic tooth brush, a sample size (35 or 50ml) of toothpaste, a disposable razor, 100ml bottle of shapoo, 100ml bottle of conditioner, a bar of soap perloined from a previous hotel visit. Smelly and squirty stuff bought in duty free when needed.

Well I think it's brilliant! I echo that a bigger toothpaste tube might be handy, but I like that you've made it fully-reusable instead of just having a compartment to put a non-recyclable one. One benefit of your design that I'd highlight is that you can fully remove the toothbrush head part to clean inside the tube (I think that might get a bit icky inside after a while but you can clean it with your design).

Edit to add - a syringe might be a good toothpaste tube (if you can fit it) as you then have a way of sucking it in and pushing it out. Might need to somehow detach the handle from the piston though.

You may have it somewhere else but one way of showing it off better is to have one or two photos with lines to each part with a number.

You can then have a section below it with a tabular format for description of each part, saying what the material is, how it is machined etc. Think of a manual for a product.

Don't forget the 'why' marks as well. Why did you choose HDPE, why PLA, why the dimensions given etc..

My feedback on the device itself: tooth brushes get dirty, how will you be able to clean the bit underneath the screw hole? It looks awkward to get a sponge into.
