Our final product is a carpet sample dry mop. It consists of a wooden handle that is attached to our 3D printed ball and socket joint with a pin. The joint is screwed to a small wooden block which is stapled to a piece of industrial carpet. A softer wool carpet sample is attached to the bottom of the mop with six snaps. The snaps were superglued to the industrial carpet sample and sewed on to the corners of the wool carpet sample.

Abstract

The objective for the team, Empire Today, was to find a way to add value to SCRAP Humboldt's donated carpet samples. We created a carpet sample dry mop that would function as an effective dusting device of hardwood, linoleum, and tile flooring. It features 3D printing of a ball and socket joint that connects a handle with a head comprised of carpet samples. This design will help divert carpet samples from the waste stream. There were other designs and iterations that were considered, but the carpet sample dry mop proved to be the best solution to the problem. [1]

Background

SCRAP Humboldt[2] is a creative reuse center in Humboldt County, California. SCRAP Humboldt aims to take materials that can still be used to create new products. SCRAP teamed up with Humboldt State University students enrolled in Engr 215 Introduction to Design [3]to promote sustainable living by challenging teams of to create projects that were aimed towards diverting usable materials from the waste stream. One of the materials in particular was carpet samples. From this project assignment the Carpet Sample Dry Mop was created.

Problem statement and criteria

SCRAP Humboldt has an abundance of donated carpet samples, but no practical use for them. Team Empire Today thought to make a dry mop out the carpet samples. The table below shows the criteria that was important for the dry mop to have, its definition of the criteria, as well as the level of importance.

Criteria Weight (1-10) Description
Functionality 9 Must be able to rotate 360o smoothly.
Usability 8 Easy to use.
Quality 7 Able to last at least a month. Must survive multiple washes.
Durability 7 Able to last at least a year. Must survive multiple washes.
Cost 6 Must not be more than $15 or more than a similar products on the market.
Sustainability 6 Be made from mostly recycled material.
Aesthetics 5 Must be pleasant to look at.

Description of final project

Our final product is a carpet sample dry mop. It consists of a wooden handle that is attached to our 3D printed ball and socket joint with a pin. The joint is screwed to a small wooden block which is stapled to a piece of industrial carpet. A softer wool carpet sample is attached to the bottom of the mop with velcro. The velcro was superglued to the length of the industrial carpet sample and to the length of the wool carpet sample.

Testing Results

Result Description
CarpetSampleDryMopTestingResult.jpg
During our testing we used the carpet sample dry mop on linoleum floors. The floor was dirty with large pieces of trash, dirt, and dust. It was able to navigate smoothly in tight spaces and pick up much of the dust and dirt.

Materials

  • Old broom or mop stick (preferably wood)
  • 1/4 in diameter bolt and nut (bolt needs to be 1-3/4 in long)
  • 3D printed joint (link)
  • O ring with OD = 1-7/16 in and ID = 1-5/16 in (wall = 1/16 in)
  • 4 screws ( 3/16 in diameter and 3/4 in long)
  • Wooden block (dimensions = 2-3/4 X 1-1/2 X 3/4)
  • Staple gun and staples
  • Carpet Samples (one with soft material for mop head and one with sturdy backing to attach head to the joint)
  • Velcro (1 foot cut into 4 equal sections)
  • Drill
  • Super glue
