ABSTRACT

Typical newspapers machines are based on the honor system. People are expected to

pay for one newspaper and take one newspaper out of the machine. However, this act of

“honor” does not always happen. Because all of the newspapers are exposed, there has been

abuse to the honor system. It has gotten to the point that people pay for one newspaper and

take the entire stack. As a result of the hard economic times, thousands of dollars have been

lost due to newspaper thefts. There are plenty of single dispense newspapers that have been

designed, but because of its electrical components, it has been discontinued due to the high

cost in manufacturing and production.

Designing and developing a single dispensing newspaper machine without an electrical

component will help solve this current problem. This machine will be a more viable option

to produce since it will not include any expensive electrical parts. With the use of a simple

coin slide, the customer will be able to access a newspaper with ease.

The operation of this machine is very easy to use. Simply insert the money into the coin

slide, push the slide in all the way, and pull the slide back to its original position. Once the

customer pulls the coin slide back into its starting position, one single newspaper will

dispense though a slot where the customer can easily grab the newspaper. When there are no

longer any newspapers in the machine, the customer will be unable to operate the coin slide.

If it does not slide then the machine is out of newspapers due to a straightforward sold out

feature.

This prototype machine was made entirely out of wood with the exception of specialty

and ordered parts/hardware. The concept of this design may be retro-fitted into other

newspaper machines or can be replicated with other materials other than wood. Newspapers

can be bulk loaded and can handle about 20-25 newspapers at a time. The newspaper

machine can be modified or customized to dispense other types of newspapers if needed.

The only modifications that will have to change are the springs, which index the newspapers

up, and the pusher/puller that catches the newspaper and slides it forward.

The proof of design requirements were all met and the completion of the prototype was a

success. Though there were some minor setbacks during the manufacturing process, overall

the project was on schedule and completed to its entirety.

INTRODUCTION

BACKGROUND

Newspaper companies have always used the "honor system" when selling newspapers

from machines. The concept is that buyers will pay for and take only one newspaper. Since

the debut of "Extreme Couponing" in spring of 2010, high rates of newspaper theft have

occurred to acquire coupons. It is believed that $2,000-$3,000 have been lost to theft every

month (1). Stolen newspapers are often stolen to be resold at local stands at a higher price, or

even just the coupons itself has been stolen and not the actual newspaper, as "coupons from

the Sunday editions are in high demand." (2) Despite the reasons of why the newspapers are

stolen, "It's a crime and people will be punished if caught." (1)

The focus of this project is to design a dispensing mechanism and enclosure that will

only dispense one USA Today newspaper at one time. The biggest feature for this particular

machine is to design for ease of use and operation thus allowing anyone to be able to use this

machine despite gender or age. Single dispense system will prevent exposure of all the

newspapers within the machine, therefore resulting in the elimination of theft. The design

will prevent coin slide from accepting any more money when the machine is sold out. This

helps ensure that the customer does not throw away money into the empty machine.

COMMERCIAL OPTIONS

MEDIA SAFE SINGLE UNIT NEWSPAPER DISPENSING DEVICE

The Media Safe Dispensing Device, as seen in Figure 1, is designed to replicate the look

and function of the typical newspaper machine. This particular unit is different because it

guards the newspaper stack instead of exposing all of the newspapers, forcing the customer

to grab only one newspaper. When loading the newspaper, the newspaper is loaded one by

one into each unit shelf. The problem with this particular unit is that the loading is rather

times consuming by loading each newspaper one by one into each slot. In addition, the size

of the newspaper compartment is predetermined, therefore prohibiting flexibility of

newspaper quantities.

GLOBAL NEWS VENDING WALL MOUNTED WM-2000

The WM-2000 is not the typical newspaper machine design. As seen in Figure 2, it is

wall mounted and features a unique pull arm design where a pull handle is used to dispense

one newspaper. This can cause a potential problem for shorter customers if the unit is

mounted at a higher level because the consumer will be unable to reach the pull handle.

The ability to find a wall to mount this unit can be troublesome due to the fact that

permission will be needed from the building owner. Once permission is granted, the time to

mount the unit will be inconvenient, not to mention if the unit is to be removed, more time

will be needed to disassemble the unit from the wall, and the wall itself will be unpleasing

with the holes from the mounting assembly.

WURLITZER NEWSPAPER VENDING MACHINE

The Wurlitzer Newspaper Vending Machine shown in Figure 3 is a large newspaper

vending machine that will vend one newspaper at a time. The Wurlitzer vending machine

requires a power source to function, resulting in limiting the unit to be placed inside or near a

building. In addition, because the unit is so large, portability is an issue if the machine were

to be moved to another location.

Figure 3 – Wurlitzer Newspaper Vending Machine (5)

The products that were research either were discontinued or required a power source.

Almost all of the units that require a power source will require expensive parts and if the

electrical system became faulty, it will be costly to replace. Based on the available products

on the market, some of the features from current products will be incorporated into the new

design of this project. By doing so, this will allow ease of use and high customer

satisfaction rates. The remaining products that have been researched can be found in

Appendix A.

CUSTOMER FEEDBACK

SURVEYS

In order to determine what customer needs were for this project, sixteen surveys were

distributed to newspaper buyers, college students, and engineers around Cincinnati, OH.

Customers were asked to rate the importance of functions and features of newspaper

machines as well as their current satisfaction based off a "five point" scale. A score of 1

would be low importance/satisfaction and a score of 5 would be high importance/satisfaction.

Below, in Figure 4, shows the differences between the customer's current satisfaction and

importance of features. Appendix B shows full survey and calculations.

Figure 4 - Customer Importance and Satisfaction

The bar graph in Figure 4 showed the highest rating of importance on ease of use and ease of

operation, followed by durability and ease of loading. With these results and evidence that

improvements need to be made, new design concepts will address these desirable features as

the voice of the customer.

CUSTOMER REQUIREMENTS ANALYSIS

The data obtained from the customer survey was organized and interpreted by using the

Quality Function Deployment. For full QFD results please refer to Appendix C. The

"Designer's Multiplier" column is a multiplier chosen by the designer to increase the

customer importance reflected in the survey. The "Planned Satisfaction" column, seen in

Table 1, are the scores that the designer would like to achieve upon completion of the

product. Ideally, this column will boast higher numbers than the current customer

satisfaction due to the fact that the goal is to have the best design that will outperform the

current market product and better satisfy the consumer. These two values affect the

customer's importance values and influence the relative weight percentages.

Because the main point of the project was to prevent the theft of all the newspapers, a

designer's multiplier was added to the secure portion of the features. Likewise, because the

ease of operation and use were the highest importance, adding the multiplier to the ease of

loading will alleviate any further difficulties should there be any.

Engineering characteristics are considered key items by the designer, to incorporate during

the not only in the design but also the manufacturing of the product. Table 2 below are the

engineering characteristics, which shows, what features and requirements the designer feels

are important to the customer and what requirements would satisfy the customer.

Table 2 - Engineering Characteristics

Using the engineering characteristics and the results of the customer importance/satisfaction,

the product objectives were created. The following explains the product objectives and uses

the engineering characteristics to describe how each objective will be measured.

DISPENSING MECHANISM DESIGN

ALTERNATIVE CONCEPTS

Three concept sketches were considered are shown below. First, below in Figure 5, the

pusher/puller design simply pushes/pulls the newspaper forward towards the consumer. The

small back will make contact with the fold of the newspaper and slide the newspaper towards

a slot, which then allows the customer to pull the paper.

Figure 5 - Pusher/Puller Concept

Single Dispense Newspaper Machine Peter Tran

10

Next, Figure 6 shows the friction material concept. This function is similar to that of the

USPS mailbox. It allows the customer to open the lid and drop in the mail but at the same

time, it restricts access to the other postage dropped by other customer. In this design, the

customer will open the lid, which then slides a friction material across the top of the

newspaper, orienting the newspaper up so that the consumer can grasp the newspaper.

Figure 6 - Friction Material Concept

Single Dispense Newspaper Machine Peter Tran

11

Lastly, Figure 7 demonstrates the roller concept. This design concept is a mixture between

the pusher/puller concept and the friction material concept. The roller will have a friction

material on the wheels, which will then slide the newspaper forward towards the front of the

machine. Once the newspaper is far enough, the customer can then pull the newspaper out of

the machine.

Figure 7 - Roller Concept

Single Dispense Newspaper Machine Peter Tran

12

DESIGN SELECTION

The weighted method was used to determine the best concept to use as a design. Table 3

displays the relative weight of each product objective that was used in the QFD. A five point

scale was used to rate each design on how it addressed the criteria (1 being poor and 5 being

excellent). The deciding criterion was the ease of maintenance, which ultimately decided the

best design. Because the friction material would need to be replaced more often due to wear

in the friction material concept and the roller concept, the scores fell short from the

pusher/puller design. The pusher/puller design had the highest score at 3.12 to become the

best design to meet the product objectives.

DESIGN

PUSHER/PULLER This design is essentially a long hook. The plate has teeth on the bottom and has a very small

radius in the bend as seen in Figure 8. The radius in the bend is very small and will be able

to line up with the fold of just one newspaper. Shown in red in Figure 9, the teeth will be

able to catch the newspaper on the fold to advance the newspaper forward. The combination

of the teeth and the small radius bend will allow to pusher/puller to consistently grab hold of

one newspaper at one time. The bottom of the pusher/puller is flat allowing it to slide across

the newspapers without any damage to the next paper.

FRAME DESIGN

The illustration below in Figure 11 is a frame design similar to the type of frame that is used

for the current USA Today newspapers. It is a small box top and with the ability to attach to

a pedestal of any height desired. With this frame, a commercial coin slide has been

incorporated to the machine, which will control the dispensing mechanism. Furthermore,

Figure 12 shows an inside look of the machine's concept and basic function.

The base plate that holds the newspapers will be indexed up with the use of extension

springs. As seen in Figure 13 and 14, there are a total of 4 springs. The placements of the

springs are located in the front and the back. An estimated force that the springs will

undergo is approximately 11 lbs. The 11 lbs include the weight of the newspapers, the rail

slides, and the newspaper base holder. The springs will travel about 6 inches and since the

force has been determined, the spring constant can be calculated. Once the spring constant is

solved, the springs can then be purchased. The spring calculation can be found in Appendix

G.

DISPENSING OPERATION The images below highlight on the dispensing mechanism. Figure 15 shows the starting

point of the dispensing mechanism once the coin slide has been pushed in all the way. Once

the coin slide has returned to its original position as seen below in Figure 16, a portion of the

newspaper is through the slot for the customer to pull and obtain. Please note that the

starting and ending position of the dispensing mechanism are the same.

In order for the pusher/puller to grab the newspaper, it can retract further than the actual

newspaper. Below in Figure 12 shows that the newspapers will be held in place with a

newspaper back support to allow the dispensing mechanism to retract further than the actual

newspaper, and to also allow the pusher/puller to index the next paper.

Figure 17 - Newspaper on Back Support

The base holders for the base plate are attached to rail slides to assist in a smooth and even

ascend of the newspapers. Figure 18 are the locations of the rail slides (red) for the

newspaper base holder.

Similar to the base rail slides, the dispensing mechanisms are also attached to rail slides.

Figure 19 shows the rail slides (red) for the dispensing mechanism. There are two sliders in

total and located on opposite sides of each other. This ensures a smooth and minimal effort

slide for the dispensing mechanism. This also helps the customer to exert a minimum force

when pushing in the coin slide.

Figure 19 - Rail Slide Locations for Dispensing Mechanism

LOADING OPERATION There are hooks incorporated on the bottom of the newspaper base plate and on the bottom of

the machine. There will be a rope attached to the top hook to help the operator to pull the

base plate down. The end of the rope will be a carabineer to fasten the base plate in place.

This will help the operator to bulk load the newspapers into the machine faster and in a more

convenient way. The use of the rail slides from Figure 18 allows the operator to easily

modify the newspaper base up and down with minimal effort and force.

Figure 20 - Loading Hooks Location

SOLD OUT FEATURE

To guarantee that the customer does not waste money on the machine when there are no

more newspapers available, a sold out feature has been added in. The location of the plunger

can be seen below in Figure 21. The plunger can pivot up and down through the dispensing

mechanism holder and the base plate. The function of the plunger and the sold out feature is

very simple. When there are newspapers present within the machine, the plunger will be

suspended up and not lock in place. Figure 22 below shows a close up of the plunger position

when there are newspapers present.

Figure 21 - Plunger Location

Figure 22 - Plunger Position with Newspapers

Single Dispense Newspaper Machine Peter Tran

21

The top portion that is holding the plunger is the dispensing mechanism holder. Both Figure

22 and Figure 23 show the dispensing mechanism holder. The holder simply has a hole

drilled for the plunger to fit through it. It is large enough for the plunger to slide up and

down effortlessly.

Figure 23 - Plunger Position without Newspapers

Shown in Figure 23, once there are no more newspapers present the plunger will fall though

a drilled hole in the base plate. By falling though the base plate hole, the dispensing

mechanism holder and the base plate are locked together, therefore prevent the coin

mechanism to slide and confine the coin slide to move. The top portion of the plunger,

which is highlighted blue in Figure 23, has a larger diameter to prevent the plunger to fall

completely though the dispensing holder.

FABRICATION AND ASSEMBLY

Because a prototype was made, the majority of this project was fabricated out of wood.

Figure 24 shows the first steps of the frame fabrication and assembly. The plywood was cut

using a table saw and assembled using wood screws.

Figure 24 - Beginning Frame Fabrication

The base plate holders again were mounted to rail slides for ease of use and convenience.

Figure 25 shows the base plates assembled to the rail slides for both sides. On the back of the

machine are just two plywood boards to make the back support for the newspapers. The

thickness of the back support is large enough or the dispensing mechanism to retract further

than the newspapers.

Figure 28 - Spring Assembly and Loading Hooks

The spring assembly and location can be seen above in Figure 28. As mentioned above,

there are four springs in total. Two in the front and two directed behind. In addition, the

loading hooks are mounted as shown. A rope is attached to the top hook located under the

base plate and a carabineer is attached. This helps hold keep the base plate in place while the

operator is loading the machine. Figure 28 shows the base plate being held in place with the

completed loading assembly.

TESTING AND PROOF OF DESIGN The testing methods were minimal. Once the assembly was completed, the loading test

was accomplished first. Performed by myself and volunteers of both men and women. First,

the rope was pulled and connected to the bottom hook numerous times. Second, the same

group of volunteers loaded the newspapers in bulk. This test was done about 30 times from

the volunteers, and about 100 times myself. The next test was the most important one.

Testing the machine to reliably dispense one newspaper at one time. This was done by

inserting the money into the coin slide and watching to see if only one newspaper is

dispensed. This was performed by myself and also with the group of volunteers. The

volunteers test the machine about 20 times each and I tested the machine about 200 times.

The proof of design test was completed in the presence of the advisor. Appendix D lists

the Product Objectives, which was the checklist used to prove the design of the machine.

Every objective was met and was tested by the advisor to see if the unit dispensed one

newspaper at a time. Furthermore, during Tech Expo, the machine was set up for the public

to use and the machine executed perfectly.

PROJECT SCHEDULE

Below is a project schedule using a modified version of a Gantt chart. Table 4 shows

everything to be completed such as design, purchasing, fabrication, assembly, and testing.

Early on the dispensing mechanism design turned out to be much more difficult than

expected. This caused the schedule to fall apart and caused some major setbacks. Once the

dispensing mechanism design finally came to conclusion, it was difficult to catch up with all

the required designing. To see the full-itemized schedule, see Appendix E.

Table 4 - Itemized Schedule

BUDGET

The preliminary budget shows how much this prototype machine would cost. The

proposed vs. actual budget is estimated for a machine frame made with metal vs. wood.
