1. DesignOverview

TheSauceBot is anautomatedmachine that allows forhockeypuckpasses

without the assistances of a coach or player. Our design has multiple different

subsystemstoensurethepassisaccurateandsafe.Inthenextfewsections,wewill

giveadetaileddescriptionofhoweachsubsystemworks.

1.1HopperSystem

The hopper system (see Figure 9) was a subsystem introduced into our

design to further assist players and coaches. It reduces the time required for

coaches and player to load the machine because hockey pucks can simply be

dumpedintothehopperandwiththehelpofbrushesandasmall12Volt-DCmotor

spinningatapproximately30RPM,thepuckswillbepushedintotheopeningwhere

theywillfalldowntheramp.Thehopperhastwocomponents,whicharetheinner

hopper and outer hopper. The inner hopper is made of plastic or sheet metal,

rotates,andhasmanydifferentbrushestoaidwiththemovementofthepucks.The

outerhopperisstationary,madeofsteelandactsasasupporttoensurethepucks

sitverticallyatthebottomofthehoppersubsystem.

1.2Ramp Therampisaveryimportantcomponentofthedesignasittakesthepucks

inaverticalpositionfromthebaseofthehopperandbringsthemtothebaseofthe

ramp where they will sit and wait for the solenoid to punch them flat onto the

conveyorsystem.Thematerialoftherampistobeplasticorsteel,whichwebelieve

tobeagreatmaterialinallowingthehockeypuckstoslidefreely.

1.3Conveyor

Theconveyor’sresponsibilityistotakethehockeypuckfromthebaseofthe

ramp to the firingwheels found at the front of the design. This conveyor is best

illustratedinFigure2andwillbedirectlymountedtoa12Volt-DCmotorspinningat

E N G R 4 5 9 5 S a u c e B o t P a g e 10approximately 300RPM. The frame and rollers are made of steel and the belt is

madeofrubber.

1.4FiringSystem This subsystem is themost important aspectof theentiredesign. It allows

for the shooting of the hockey puck, which is the main purpose/objective of the

design.Oncethepuckhasbeenbroughttothesewheelsbytheconveyor,thepuck

willbeacceleratedthroughthesmallgapbetweenthewheels,resultinginthepass.

1.5RotatingSystem

The rotating system is one of our designs most unique subsystems, as no

similarexistingproductshavethisaspect.Togetavisualunderstandingofhowthe

rotating system functionswith thehelpof anelectrical linearactuator, seeFigure

2. ConceptDevelopment

Duringthelastfewmonths,ourgrouphasmeteveryWednesdaytodiscuss

designideas,issuesthathaverisen,anddetailedplansonwhateverygroupmember

wasrequiredtocompleteforthefollowingweek.Ontop,Dr.Timuskhadgivenus

weeklyassignmentstoensureasagroupwestudiedallthepossiblesolutions,and

then displayed our reasoning behind why we chose our final concept. All the

assignmentsareclearlydefinedorillustratedinthesubsectionsbelow.

2.1ProblemStatement

AsCanadians,manyofusare familiarwith theexpenses that surround the

gameofHockey.Foryears,teamsandorganizationshavespentcountlessdollarson

the training of players and goalies through coaching, exercises and costly

equipment. This has led our group to develop a cheaper alternative to multiple

formsof training.Ourproductwill offer the consumeranall-in-oneexperience to

fosterskillsinmanyareasofthesport.

Parentsorplayerswilloftenspendoveronehundred(100)dollarsperhour,

for an on-ice skills session. Themajority of the time an instructor or coachwill

simplyspendtimepassingandshootingthepuck,ratherthanfocusingontheskill

developmentoftheplayer.Avastproblemthatexistswithcurrentproductsisthe

cost associated. These prices range anywhere from $1300-$1500, another very

pricypurchasethatparentswillneedtoundertake.Theprototypewecreatewillbe

an automated passingmachine that will allow for a greater focus on player skill

cultivation. The device will also provide the opportunity for an individual to

developskillsindependently.

Intoday’shockeymarket,thereareveryfewpuck-passingmachines,noneof

which are capable of projecting the puck at various angles. Furthermore they are

unable to utilizemobile devices for the operation. The devices that do exist are

E N G R 4 5 9 5 S a u c e B o t P a g e 12quitebasic;astheyonlypassinonedirection,operateusingatimer,andrelyonan

electricaloutletconnection.

2.2FunctionalRequirements

1. SizeandWeight:Thesuitablesizeandweightofourproductshouldallow

foreasymaneuverabilityandtransportation.Themaingoalistoensurethat

either two parents or two players are capable of lifting the product into a

vehicle.Thematerialusedtoconstructourproductwillbevitaltomeetthese

sizesandweightconstraints.

2. SystemControl:Thesystemcontrolshouldbeveryuserfriendly,whichwill

allow younger players to use the product without the help of an adult.

Operationsmaybecontrolledwiththeuseofahandheldwirelessdevice,as

wellasswitchesandcontrolsonacontrolpanel.

3. Cost:With a complex design, we will ensure the minimization of cost. A

reasonably priced product is vital as it will be competitive with existing

devicesinthemarketplaceandappealingtotheconsumer.

4. Speed and Capabilities: Speeds will vary so that both young and highly

skilledplayerscanusetheproduct.Theoptionofdeliveringdifferenttypesof

passeswillenhance theuserexperience.Furthermore theability topassat

various angles can increase the consumers’ interest in the product. The

productwillbeconsideredmaneuverable,withtheeliminationoftheuseof

anelectricoutletandutilizingabattery.

5. Care and Maintenance: The devicewill need to be charged on a per use

basisasitwillberelyingonbatterypower,insteadofusingelectricityfrom

an electrical outlet. The design will allow for easy access to the internal

components,ifmaintenanceisrequired.

6. Loading:Loadingpucksintothedeviceshouldbeaneffortlessprocess.The

capacity shouldbe largeenoughsuch that itdoesn’thave tobe refilled too

often.

2.4PughMatrix The Pugh matrix is a great tool to use during the designing process of a

product.Itclearlyoutlinestheimportanceofeverysubsystemandaddsupthetotal

numberof positives andnegatives. It is very efficient to comparedifferentdesign

ideasduetothenumberingcriteriaandthenselectthemostsuitabledesignforyour

While deciding upon a design many different options were analyzed and

discussedasagroup.Itwasnecessarytoinvestigatefurtherintopossibledeignsto

seewhat technologiesandormethodsalreadyexisted, andwhetherornot touse

thesepre-existingdesigns.

It was interesting to find that one group of engineering students from

DalhousieUniversitycompletedadesignprojectwithsomeaspectssimilartoours.

Theydesignedapuck-passingmachinethatrequiredtheusertoloadpucksbyhand

and could only fire a puck in one direction without the user having tomanually

changethedirectionthepasserwasfacing.Inadditiontothistheuserinterfacewas

modify any of the system settings they would have to walk to the machine and

changeit.Afterseeingthis,ourgroupagreedthathavingeitherawirelesscontroller

orasmartphoneapptocontrolthedevicewouldbeideal.

Fromconducting further research,wewere able to find a companynamed

Pucco, located in Sweden. This company has developed several models of puck

shooterswith commendable characteristics. Therewas amodel of theirmachine

highaswell:over$5000CAD.

The Puck Passer Pro was another machine used for a similar task as the

Saucebot. This apparatus was smaller and lighter than the Pucco, however the

loadingandpowersourcesweresubstandard.Althoughitwasabletoshootpucks

atupto40milesperhourandat incrementsas lowas2seconds, itrequiredwall

power,aswellasmanualloadingofonlyupto18pucks.

that allows the user to simply dump a bucket of pucks into and continue on

machines like separators and vibratory sorters to give us a better idea of any

technologies we could use. Although the research was inconclusive as to a final

it sparked many new ideas within the group. With all previous aspects of

to come up with a relatively compact sorting system that could be used in our

application.

6. PreliminaryTestingandAlternativeSolutions Since the beginning of September we have discussed several alternative

solutions to theonewehave finalized inour conceptproposal.The figuresbelow

are quick sketches of these different ideas. For the firing system we considered

multiple systems (see Figure 7) including a belt driven system, a linear actuator

punch, and a sling shot design.Aftermanydiscussions,wewere able to conclude

thatthewheeldrivensystemwasourbestoptionduetoitsreliabilityandefficiency.

Figure7:Differentoptionsthatwereconsideredforthefiringsubsystem.

Many different hopper designs were taken into consideration during

discussionsofourdesign.Wewantedtobedifferentfromanyotherproductfound

on themarket. Other considerations included a single/multiple tube loader and a

vibratinghopper(seeFigure8).Wedecidedthesingle/multipletubeloaderwasnot

6.1 FiringSystemPhase1:

Figure10:Thisfiguredisplaysthemainconceptofourinitialpuckshootingtests.

Thiswasoneoftheveryfirstconceptsthoughtof,whichlaterdevelopedinto

the final firing mechanism system chosen. This system simply utilized pucks

attachedtometalrodstoacceleratethepuckthatwouldbefired.Theframeoftest

unitwassimplyconstructedoutofwood,asscrapwoodwasreadilyavailableinthe

machine shop. With testing we found that the use of hard rubber wheels was

unfeasible, as thepucksdidnotgripwell enoughevenwhenanabrasivematerial

such as sandpaperwas added to the outer edge.Also, the diameters of the pucks

weremuchtoosmalltoreachpassingspeeds.Withmotorspeedsofapproximately

2000 rpm, initial testing resulted in a puck velocity of 1m/s. This completely

eliminated theuseofhard rubberwheels forour firing systemas they lacked the

abilitytoefficientlyacceleratethepuck.

E N G R 4 5 9 5 S a u c e B o t P a g e 36

6.2HopperSystemPhase1:

Figure12:Firstconceptofapuckhopper.

The first concepts that we developed when thinking of simple loading

hoppers, which allowed for large numbers of pucks to be loaded without

placing/stacking pucks,were simple rectangular hoppers (example above). These

hoppers would be vibrated to allow for pucks to easily exit the hopper. These

systemswereconstructedoutofcardboardtotestforjammingandotherproblems

thatmayoccur.Whenwetestedthesehoppersjammingoccurredonaregularbasis,

andbothprovedtobenoisy.Forthesereasonswewereabletoruleoutrectangular

After discussion and several other hopper ideas our group conceived a

potentialhoppersystemthathadlowchancesofjammingandwouldallowforlarge

numbers of pucks to be loaded without placement. This system has a stationary

outsidewitharotatingmiddlesection.Thepucksexitthroughthecutoutslotinthe

stationary exterior. To determine the validity of this design a simple model,

constructedofsheetmetal,wascreated,whichprovedtoworkextremelywell.The

constructionofthemodelwasnotveryprecise.Evenwiththeseproblemsthemodel
