1 Course 1 GNEG 1103 Introduction to Engineering Spring 2015 Assignment Team Design Project Selected Topic Club and Golf Ball Cleaner Project Presentation April 23, :00-5:00 Team Members Sawyer Allen Mitch Nuckols Palmer Lane Sergio Sonora Instructor Dr. A. Stratigakis

2 Abstract 2 The members of the team have decided to create a duel golf club and ball washer. This washer will be designed to attach to a golf cart, for convenience around the course. There are discussions about the size and materials, along with how to place the brushes within the container. The plan was for use by golf courses to buy for their carts that guests shall use. We wish for a product that is not to clunky, can clean both balls and clubs effectively, and relatively easy to use.

4 4 Introduction The objective is to create a cost effective product that allows individuals to enjoy a game of golf with the convenience and ease of a ball and club washer attached to their cart for easy use on every hole. As a bonus the plug in the bottom of the cleaner can be easily removed for easy cleaning and refilling. The idea is for every golfer to be able to wash their ball and club at any point throughout their game instead of having to wait for a random hole that has a golf ball cleaner. In order to address this objective Clean Clans was born. The five team members come from a diverse background and each member brings their own ideas and expertise. Beyond the goal of creating the cleaner, the team aims to create a streamlined manufacturing process, an easy to use assembly, and a ball and club cleaner that has easy to control variables. In attempting to address these issues the team will also try to maintain usability and create a situation where amateurs and professionals can get the same quality clean club and ball for every hole, or even every stroke if they wish.

5 5 Requirements and Constraints Container must be water tight Device should be easy to use. The wheel needs to spin fast enough to clean. The cleaner must clean both balls and clubs The Needs to attach to the side of a golf-cart

6 6 Basic Features Two spinning circular bushes, along with stationary brushes Painted black for aesthetic appeal Operated by the push of a button. Cleans golf balls, and Clubs Attaches to golf-cart for convince around the course Small plug at bottom to drain old water

7 7 Engineering Design Method Identifying the need and defining the problem. Deciding on a project we jumped form one idea to the next. Our ideas started in a range of ideas from catapult to solar powered RC car, finally the idea was mentioned and decided on by the group to build a golf ball cleaner. Later the idea was added, to make ours stand apart from others we could find after a quick search, to make our cleaner also clean the golf club along with the balls. Identify Constraints and Criteria for Success Time- The project needs to be completed by April the 23 rd Aesthetics- This design is not very focused on aesthetics Performance- it must clean both balls and club effectively, consistently, and with relative ease. Safety- the biggest concern with this project would be between the water and the electric motor. Effect on Surroundings- it is intended to be placed on the golf cart Availability- the cleaner is mostly intended for sell to a golf course or country club for use on their carts for the convince of their guests Ease of Assembly/Use- the cleaner will come pre-assembled only needing to be attached to the cart/cart battery, and filled with water. To use you only need to insert the balls and or club and press a button. For emptying the water for fresh water just pull the plunger on the bottom.

8 8 -Search for Solutions Once the problem of what we would be designing was solved, then the problem of how to accomplish this was underway, the possiblility of one rotating brush in the middle was thought, the id on having a bush that was essentially on some sort of belt that moved in that way. We decided that we did not need a brush on both sides of the balls to move, but if we had one, it should rotate the ball against the other one. Feasibility Study After much discussion it seemed that we had two options that would work best for a duel cleaner of golf balls/clubs. One was a container with two moving circular brushes, one on the side for the clubs and one on the side with the balls, each against a stationary brush with a tray that lowered the balls into the brushes. The other possible option was a brush on a belt that would on one side rotate the balls against stationary bushes and down a track from the top of the apprentice to a dispenser below, and on the other side would clean the club. Potential Solutions Ball track with one spinning brush on a belt Ball holder with one spinning circular brush Preliminary Design The standard design evaluation matrix below was used to evaluate the two designs. Each property was given a weight from one to five and a score on the same scale.

In the end it seemed apparent that the circular brush was going to be our design for the Detail Design Now that we were done with the preliminary design, we moved forward to the detailed design of a cleaner with two spinning circular brushes with a removable trey for the balls. We built an 8x8x10in container of Plexiglas made to be the container for the brushes and water, then we put up a Plexiglas wall in the middle which we attached the stationary bushes on either side

10 10 of. We then cut two circular pieces of Plexiglas 6in in diameter and attached brushes to both. We then attached these with a rod through the middle of the box that would be turned by the motor in turn turning the brushes. The most difficult task of the project was determining how to set up the trey for the balls. The original attempt was to have the fellows in the EMPACTS lab help us, however our first rendition of the trey was too large for their 3D printer. So we decided to make them stand alone platforms and connect them later with threaded rods. This however was not sturdy enough for our machine. We then made the trey connected in design and then supported by metal rods, and that worked fine. Cost Structure Manufactruing Expense 11% 22% 22% 45% Plexiglas Brushes Metal rods Motor This pie chart displays the percentage of the budget that went with the individual pieces of the cleaner the total cost was around $90. The largest part of our budget went to the cost of

11 11 Plexiglas, we believe that we could cut that cost down significantly by using a prefabricated box that would fit our needs. The product that we made, we could not find any other product that were motor powered golf-ball and club cleaners so therefore we do not really know how to compare to competitor prices. However you can buy a manual ball cleaner for $40-$90 to attach to the back of your cart, and for the stationary ones found around the course around $130-$230 so we feel confident we could sell it for $250, making a profit of $140 per cleaner.
