Let’s Solve Water ChallengeXYLEM /PTC/ IgKNIGHTers September 28, 2013

Before we get started, who is Xylem?

A company focused on water• We develop products and systems that:

- Treat water to make it potable (drinkable)- Transport it to where it’s needed (here’s where your solutions come in!)- Test and analyze water- Clean it for reuse after its many uses

• We are a global company and our products can be found in every corner of the globe in places like: - hospitals- airports- schools- sports stadiums- homes- hotels- just about everywhere

Welcome to the LSW challenge!

Goals of the challenge• Provide you with an exposure to water engineering problems• Expose your teams to the complete design process from concept inception

through cad and production• Support FIRST Robotics teams through opportunities to earn awards and

develop expertise without the burden of significant cost of participation

Overview of the challengeWe are very excited to introduce you to the Let’s Solve Water Challenge. This contest will allow you and your fellow students the opportunity to contribute to solving one of the most important issues facing our world today---developing a product that has the potential to bring water to the people who need it.

Water pumps, of all sizes and types, are what all of us depend on for the delivery of water.

Your challenge, should you choose to accept it, is…

Building your own water pump

In this challenge you’ll be asked to modify an existing pump to be human powered. Not all areas of the world are fortunate enough to have electric or fuel power. The pumps developed in this challenge could potentially help solve some of the water challenges faced by those in emerging markets around the world.

There are many aspects to pump design and performance and we’ve narrowed our scope to 4 unique categories.

Your pump will be judged on Oct. 19th on the following:• Cost – $1000- (calculated as cost per output)

• CAD – 1st and 2nd places offered – $2500 and $1500, respectively• Flow Rate – 1st and 2nd places offered – $2500 and $1500 respectively• Most elegant design – $3000- (rated on the combination of product/design characteristics)

How the challenge works

We’ll provide you with…• A virtual kit of parts- Working model of diaphragm pump that can be used in CREO- PTC CREO software- PTC Mathcad software

• A pump and hose kit that includes:- A diaphragm pump (model 29270-0000)- A sample hose- A copy of this presentation- Access to Xylem & PTC mentors to assist with this challenge

…you’ll turn it intoUse the resources available to develop a manual water pump that moves water in the optimal way for design, time, exertion and pressure.

More about diaphragm pump technology

Key Features• This type of pump is considered a positive displacement pump which uses a flexible diaphragm or membrane along with inlet and outlet control valves. The diaphragm is most commonly made of rubber or thermoplastic materials. The diaphragm or membrane is reciprocated back and forth using a variety of drive options (mechanical / electrical)

Why it would make a good manual pump• Self-priming, good suction lifting characteristics, solids handling (slurries, sludge), can handle viscous liquids & good run dry characteristics.

Why it might not make the best manual pump• Flow tends to pulsate which can cause hammering effect. Inlet/outlet valve requirements.

The rules of the challenge

To qualify for a prize:• Must use pump as supplied• Budget must be <$50 and be documented (keep receipts and produce BOM)• Only tubing, fittings, fasteners, small bushings, hardware type items and raw materials for fabrications may be purchased

• Components of other systems/devices may be used given budget constraints.• Must connect to sample hose supplied• Power on competition day will be from a member on your team• All inquiries and replies will be open forum to all teams• Only one award per team• Judges rulings are final

Play hard, think hard, learn and have fun! Cooperation and mutual support between teams throughout the challenge is encouraged.

Presentations & selection of winners

October 19, 2013• All teams will demonstrate a working sample of their pump • All teams will present a short (5 minute) PowerPoint presentation on their development process, challenges faced, and what was learned in the process.

• Judges will select the team member from each team who will power the pump on the day of the challenge (selected at random):

• All pumps will be judged on these 3 categories: - Cost (calculated as cost per output)- Flow Rate (1st, 2nd)- CAD Design (1st, 2nd)-PTC based only- Most elegant design

• A panel of judges (Xylem & PTC staff along with other professionals) will be responsible for all final decisions.

• Invite your friends and family to join the fun!- We will invite local media to the event; you might be asked for an interview
