Oral Fixation

When you read facts like there are about 10,000,000 bacteria living on a single toothbrush and toothbrushes must be kept at least 6 feet (two meters) away from a toilet to avoid airborne particles resulting from the flush; you wanna re-think your oral hygiene options. Sanitizing toothbrushes is a way, and something like the Ultra Violet Sterilized Toothbrush System fits in. It consists of a UV base that sterilizes the brush once placed in the housing.

The base is an expandable one that can host 2-4 UV pods (for each brush) and plugs into the shaver socket commonly found in bathrooms. The brushes have a color coded band and the heads are replaceable, so discard them and use a fresh one after every few months.

Here are some random Toothbrush facts that you may/may not have known:

  • Initially the bristles were actually the stiff, coarse hairs taken from the back of a hog’s neck was attached to handles made of bone or bamboo.
  • Boar bristles were used until 1938, when nylon bristles were introduced by Dupont de Nemours.
  • One of the first electric toothbrushes to hit the American market was in 1960.
  • Manual toothbrushes become worn out after about 3 months and are not as effective as they once were.

    More like germ-fixation. The large numbers don’t imply large danger, in actual real life, most of the bacteria on your toothbrush arrived there from your mouth, and reintroducing them to your mouth doesn’t actually tend to cause any harm whatsoever.

    Unless you live in an alternative reality where toothbrush-infections are a common cause of disease.

    philips already uses this technique for al couple of years.
    google philips sonicare!

      Perhaps this is a design proposal for a “new” version of the Philips Sonicare.

      As far as the design itself it still needs some improvements.

      The replaceable brush heads should be modified to reduce material useage (shorten,holes in connecting shaft). The connection method should be changed from threaded to quarter turn quick release. (Reduce tooling cost as well as defective part count)

    i designed a cordless sanitiser for toothbrushes for my product design degree.

    this particular idea seems flawed in that the toothbrush design would be rather unpleasant in use with the large rim on the neck. i cant see that being very comfortable in use when one is cleaning the back teeth.

    i dont see much need for the replaceable head on manual brushes either when the handle is so very cheap to produce as part of the brush itself.

    M.S.W, thanks that is a good suggestion.

    This was just a quick side project really as its been a while since I have done any modelling or rendering so there is no great depth to the project as yet. If I develop it as more of a portfolio piece I will look into the issues you have raised.

    Thanks again,
