Defining the Problem

Water taste is not always pleasantToo bland

Water flavoring is not easy to doThings to carryMessy processSeparate items

Problem Statement

Often times, water taste is unpleasant and a different flavor is desired, however trying to flavor the water involves many different components that may not be readily available at all times.

Goals

Try to make a water flavoring device incorporated into a water bottle

All-in-One design Multiple flavoring options Ability to flavor more than once

Brainstorming

Consulted with one another about possible solutionsVery different ideas

Built off each other’s thoughts to better our primary ideas

Scanned original sketches from engineering notebooks

Research and Generate Ideas

Researched if flavor is desirable Made some rough sketches Explained our primary sketches to

each otherQuestions were asked about the

possible design and how it would work

Flavoring Ideas

Car diaphragm valve for the radiatorPressure allows for the valve to openLike a push-button

• Push and flavor would come out

Syringe idea came after our second prototypeMore cost effectiveEasier to build

Testimonials

Judi-I never thought I could give up soda...hate plain water and then learned about your's. I've lost about 20 so far and am on my journey.

Specifications

Spec Quantifiable statement (testable, with constraints)

Ease of use The product conducts the flavoring process successfully 90% of the time on the 1st attempt.

Aesthetics 90% of 50 consumers prefer our design over the conventional water bottle. The design must have volume graduations.

Color Color to be determined by potential consumers.

Volume Volume will be between 0.5 and 1 liter.

Material To be determined by tests ranging from durability, cost, appeal, etc.

Specifications Con’t

Functionality Multiple tests. Encompasses no leaking, operational flavor system, no leaking occurring in flavor chamber, not a hassle to carry

Reliability/Durability Functional a set amount (30-50) uses ranging from use in washing machine, actual use refilling, drop tests, throwing tests, pressure tests, and is still operational.

Cost Has base cost that is competitive pricing compared to competing companies ($5-$20)

Feasibility Is easy to be built by local vendors and us with proper equipment (injection molding, etc.).

Usability The water flavoring system must flavor three to five times before needing to be refilled. There should be a minimum of two flavoring options. There should be a maximum of 3 processes to flavor.

Exploring Possibilities

Made secondary sketchesHad to fulfill the Specifications

Discussed our ideas and how they would work

Four (4) designs to choose from

Selecting an Approach

To decide on the design, we made a weighted constraint matrixAllowed us to evaluate the design

using our specificationsWeighed the specifications differentlyHighest score would be the best

Expert Feedback

Sent our design to experts that would be able to help usAsked them to give us feedback on

our design• Design flaws• Suggestions

Expert Feedback Con’t

Douglas Mengler Maintenance

manager at CapSonic Inc.

Emphasized the design should be simple and easy to produce Use standardized

parts Ease of manufacturing

Cost Material selection

importance

About our design: Liked the idea of

standardizing parts• Syringe

Must be knowledgeable about the manufacturing process

Multi-part assembly vs. one complicated assembly

Prototyping

Very critical stepSee if our idea is going to work

Prototype constructions was completed at Bartlett High School

5 prototypes2 testable prototypes

Testing and Evaluating

Came up with five (5) different testing proceduresMake sure our prototypes work

properlyMake sure our prototypes meet our

specifications properly

Testing and Evaluating Con’t

Ease of UseMake sure the product is able to be

used by the consumer Waterproofing

Make sure water does not leak Durability

Make sure all systems withstand use and abuse

Testing and Evaluating Con’t

Product LongevitySee how long the bottle will function

properly Cleanliness

To ensure to bottle will not keep unwanted residue from flavoring

Refining the Design

We wanted to keep our flavoring device secureFound a water bottle with a flip up cap

• Prevent from breaking when falling

Implemented our design within that new water bottle

Same flavoring process - new look

Final Solution

Thermos Intak BPA Free Hydration Bottle – Blue (24oz.)

2 Syringes (without needle) Liquid flavoring Syringe holder (attached to the cap)
