Step 1- Problem StatementSpikes/Cleats become worn out
when walking on asphalt to a field/stadium/track.
3
Step 2- Brainstorming Consider Source of Problem•Deals with cleat shoes wearing away
when walking
•Friction/ contact of shoe with track field surface
•Athletes’ amount of shoe usage
4
Background•Experience
▫Joe plays football▫Joey played baseball
•Knowledge from peer athletes ▫Conversations▫Environment▫Issues with track surface
5
6
Hypotheses•Impossible/difficult to improve upon outside factors
•So, Improve features of cleat shoe▫Design & manufacture solution to fit on
bottom of athletic cleats ▫Solution will provide protection so cleat shoe
will last longer▫This device will be effective when user is not
using cleats for their main purpose
Step 3- Research/ Justifying the Problem
•Surveys▫Random distribution (50) ▫Peers with background to problem
statement
•Expert Feedback▫Interview experts through email, in
person contact (7)
•Online research▫Patent searches▫http://uspto.gov

Market Survey1.Do your spikes/cleats on athletic shoes become worn
out after walking on asphalt/sidewalks? (If No, do not continue) Yes No
2.Which type of spikes/cleats do you use? Metal Rubber Plastic
3.What do you use spikes/cleats for? Check all that apply. Football Baseball Track & Field Soccer Golf Bicycling Work Other (please specify__________________________________)
8
9
Market Survey4.Spikes/cleats become worn out or damaged due to:
Excessive use Poor design Friction with surface
5.On a scale of 1-5, do you feel your performance is lowered because of worn down spikes/cleats? [ 1= No, not at all. 5= Yes, definitely]1 2 3 4
56.Do you feel you need to replace your spikes/cleats
because of damages? Yes No
7.If yes to #3 how often do you feel you need to replace your spikes/cleats? Often Sometimes Very few times Other (please specify__________________________________)
10
Market Survey8. Would you purchase a device that protects
the spikes/cleats from becoming worn down? Yes No
9. If a new design were to be created improving the spikes/cleats, which factor will be the most important upon purchase? Cost Quality Durability Appearance
Survey Results•36 responses in accord that cleat shoes
wear down to the point that it should be considered a problem
•14 responses in accord that cleat shoes are not worn down enough to be a problem

Solution D: Spike Plugs
Pros ConsEasy to put onSmallFits on any sized shoe
Easy to loseMay take too much time to put on
25
• Rubber plugs put on spikes
• Keep spikes from touching ground
Solution E: Retractable Cover
•Rubber membrane on outside
•Stretchy rubber material extended over sole
•Covers heel, kicking portion
•Rubber sleeve covers entire bottom
26
Innovation Solution F: Spike Plug W/ Retractable Cover
▫Spike plugs easily attach to bottom of athletic spike shoe
▫Retractable stretchy sleeve holds together spike plugs
▫Allows attachment of all five plugs without effort
▫Retractable cover provides tight support all around shoe
▫Prevents shoe laces from becoming untied

53
Step 9- Test & Evaluate•Evaluate performance of cleat covers•Individual from team make use of covers•Estimated time: 2 days to perform test 3x•Equipment needed:
▫ Team member▫ Data tables▫ Stopwatch▫ Weights▫ Prototype▫ Cleat shoes
54
Testing Aspects1. Safety
Is it slippery?Is the cleat still balanced?Do spikes become damaged with application?
2. FitDoes the spike cover fall off?Do the spikes fit within the holes?Do the covers fit the portion of the shoe?
3. Weight Capacity Max amount covers can hold
55
Testing Aspects Cont’
3. Time-Saving Easier to slip-on rather than
purchasing?4. Performance
Protect spikes from external surf?5. Physical Appeal
Product look effective? Attract customers?
56
Testing Procedure1.Safety
• Wear spike coversWalk on different surfacesIf the cleats slip on surf, it fails
2.Weight Capacity
• Wear spike coversAdd weights to the person to test the durability Record weight. Goal Capacity: 200 lbs.
Testing Procedure3. Fit
• Place spike covers on soleFail if covers fall off or become loose while walkingExamine if the spikes fit in given holes Examine if covers fit the sole of the cleats correctly (not too big and not too small)
4. Protection?
• Wear the spike cover and walkSpikes shouldn’t become damaged in any way
Testing Procedure5. Time-Saving• Time starts when he/she begins to put on the spike cover.
Time finishes when he/she takes of the spike cover. • Same person start a new time trial with spikes already on.
Start the time when he/she starts to remove the shoe. Stop the time when the other shoe is completely on.
• Compare the times. If the spike cover time was faster than the shoe-to-shoe time, the test is passed.
6. Physical Appeal• Test by giving the appearance of the product a score on a
scale of 1-10. (7 and above is a pass)

Problems in Design•There should be two layers to the shoe
Plastic: serves as the protection of the spikeRubber: serves as a safety precaution and
increases durability of the product
•Unachievable to design solution to fit all types of spikes
We chose the Nike Haurachi as our model shoe
62
Step 10- Refinement
•Redo the measurements and drawingsUsed micrometerCalculations
•Learned pressure does not help covers from staying attachedOver time, it will become loose
•New Solution = Magnets
63
Step 11- New Solution- Magnets•Magnets will be implanted into the 2nd
layer of the product•They will make the fit of the product
more efficient•Solves problem statement
Cover protect spikes? Spikes still damaged with cover on? Eliminates need to change shoes?

Magnets- Test Results• The same person performed the test procedures.• The procedure successfully tested our product
revealing problems with our design. • The testing criteria helped organize the data that
we had been looking for. • The materials were appropriately chosen based
on the results of the testing.• There was no problem found while testing that
indicated a problem with the building process.• The results showed that the design met the
criteria effectively.

Mass Production•It will be easy to mass produce our
product•Mold•Assembly
