Making a cost-effective shower header cleaning design

Project Info

Case

Our client asked us the designing a special device to be used in bathrooms. The client used to live in an area with hard water containing a larger ppm of salt, calcium, magnesium and other mineral deposits. Due to this problem, almost in all houses of the region, shower heads holes were filled and closed by water deposits. The client requested designing a simple and low-cost system aimed at removing the sediments and deposits forming on the shower head and facilitating the flow of water through the shower. The design was to be later prototyped and manufactured.

Requirements

The main requirements were the following:

  1. Easy to make
  2. Easy to mount
  3. Removing deposit without detaching the shower head
  4. Cost-effective

Solution

This problem is not difficult to resolve, as there are already a large number of standard solutions for doing this task including the followings:

  1. Using a multi-layer filtration system that is mounted on the shower
  2. Removing the shower head and soak it in white vinegar or other mineral remover solutions for a few hours

But the client needed a system that could last long without any need for replacement. Also, the product had to be cost-effective so that it could be applied to mass production. Having considered the above requirements, we proceeded with a new design. In the initial design, we made a 3-way fitting for the shower which had a hole for injecting the solvent for removing the salt and other deposits in the shower head holes.

After some testing, the proper function of the initial design was tested and successfully verified. It was offered to the client; however, because of using a valve in the 3-way fitting of the design, the client was not satisfied and asked for a solution with a simpler structure leading to a less production price.

Therefore, we changed the design and finally made a simple fitting without any valve. In this design, there was no need to use any spring and ball and so no need to use a valve. In order to inject the cleaning fluid into the system, we made it in a way that by rotating it at 90 degrees the opening was open for injecting the cleaning fluid.

Description

The design was tested and it worked well. The client was quite satisfied with the work since it satisfied all its requirements.
