Executive Summary

Delphi Automotive has identified a need for an innovative system that is safer, greener,

and more connected for trucks or cars. The majority of automotive accidents today are caused by

distracted driving. Due to this increasing problem, we have designed a system that places these

distractions in a safer environment for viewing while driving. Our system displays important

information on the windshield while also allowing the driver to keep their eyes on the road and

surroundings. The information should be see through while also remaining readable. This system

should be as inexpensive as possible to ensure that consumers purchase the product. The system

should be able to be incorporated into all types of automobile.

Inspired by road warning signs, a smart display shows important information on the road

itself. This information is color coded to elicit different responses from the driver, corresponding

to the road signs already present. The system itself is being developed to pull all of the

distractions on the road to a singular place, so they are less distracting themselves. Consumers

are not going to stop reading things like text messages or checking GPS, so the best way to make

them safer is to ensure the driver is still able to see the road while seeing the distraction.

The greatest risk to the system is overall system failure. If the system does not integrate a

phones functions correctly, the main problem presented is not solved. A multitude of trials will

be carried out to ensure this failure does not occur. Another risk is that a larger battery is needed

for the system to run. In order to ensure the system gets enough power, we will make the battery

in the cars the system is in larger. Finally, the last risk is that it has to be able to be integrated

into all types of automobile. This can cause many calibration problems. The system will be

tested in many different types of automobile to ensure that it will work in many automobiles.

Research will be done on the system and existing systems in order to fulfill the customer’s needs.

The final system prototype will be delivered on December 15th.

Introduction

Project Delphi was a creative and critical task untaken and accomplished by the team,

“New Kids on the Block.” The project involved developing an integrated part for a car which

allows the driver to be either more safe, green, or connected. After much brainstorming, our

group decided that we wanted to resolve the controversial issue of texting while driving. We

accomplished this feat by using a transparent HUD which allows the driver to read text messages

while keeping their eyes on the road. Through this idea, we are able to able to add a safer

alternative to texting while driving and also allow the driver to stay more connected to society.

Customer needs were collected through surveys, which helped mold the design of this product.

One of our key ideas that makes our design and idea unique is that we came up with a color

coding system which changes the color of the text messages on the screen to represent different

meaning. The colors chosen to represent the various meanings or signals were strongly inspired

by traditional road signs. For example, if you are reading a text and the color turns red, this

means that there is a stop sign or red light approaching in the near distance. The system can be

integrated to also display GPS and directions in an intuitive and straightforward way. Through

industrious work, our group succeeded in building and contriving this device. The overall project

was delivered successfully to our customer, “Delphi”, by December 15th, 2014.

Mission Statement

To design an integrated car part which allows the consumer to be either safer, greener,

and or more connected while driving their vehicle. This goal was ascertained through many

surveys, extensive brainstorming, and ample research. Once the idea is invented, the team

should conduct a customer needs analysis, set target specifications, concept generations, and

final design decisions. Through an organized and large scale effort while sticking to a scheduled

project plan, the goal of creating the integrated part should be met and successfully delivered by

December 15th, 2014.

Needs Statement

Based off the survey, almost all the candidates responded that they text while driving.

Furthermore, many said they even text when others are in the car with them. In today’s society,

texting while driving is generally a common act, with almost all cell phone users par taking in

the deed. The survey also showed that people have the need for a safer way to stay connected

and text while driving; responding that they would utilize a tool if one was available to do so. In

correspondence to this survey, our group decided to mold a product that allows the consumer to

continue to text while driving, but in a safe and simple fashion.

External Research

Patent Research

There are no patents that use the concept of our idea. However, we are using other patents

in the production of our overall unique idea, such as the transparent (OLED) screen. This screen

was invented by Ronald S. Cok, of Eastman Kodak Company. The original idea of the OLED

was also patented by Eastman Kodak Company, by the inventors Steven A. VanSlyke, Ching W.

Tang. The OLED is crucial for the success of our idea.

Global Market

We believe there is a huge market for the product we are manufacturing and

designing. Throughout the world, a stunning 91% of adults own and are subscribed to

cell phone usage, and 56% own smart phones. With over one billion cars worldwide, and

the explosive uprising of smartphone technology, we believe that it is time to integrate

texting while driving in a safer fashion. Our technological idea has not yet hit the global

market, and is quite unique. Thus, we feel that an integrated HUD that displays texts

messages is upcoming in the near future, and now is the time to start developing a

product as such. The market for cars and smartphones is so massive, that only a portion

of consumer’s would have to use our product for it to be profitable and a huge success.

The goal is to make our product useable by all vehicles and become a standard device

found in all vehicles globally.

Components Research

OLED Screen – Organic Light Emitting Diode or OLED for short is a screen invented in the

1980s by the company Kodak. This unique screen allows for a transparent and thin design that

would work perfectly to use within our design. The OLED is based on bioluminescence and

emits light when by using electric currents to pass through light emitting organic compounds.

The organic compounds works by using a layer of organic semiconductor which sits between

two electrodes. The OLED screen is very capable in our design because it is very thin and does

not have to be back light like an LCD screen. It is also very green and doesn’t require much

energy. These screens are produced by many companies such as Samsung, Sony, and LG, and is

starting to be used in TV, smartphones, and other devices for various green and intuitive

purposes.

Bluetooth Technology – Bluetooth technology is possibly the cheapest and easiest way to

wirelessly transmit information from your phone to the silicon Bluetooth chip in a car. This

technology allows two devices which are Bluetooth capable to synch with one another and

actively share information such as voice, music, emails and much more through short distance

radio transmission signals. The technology perfectly suits our project, allowing us to send text

messages to our developed computer system within the car; allowing us to display the texts in

our simple and easy to use HUD on the windshield or “OLED”.

Cost Model

The cost of our product to be integrated into a car is approximately $2,000. The large

OLED screen to fit half the window is $1,750, and any additional wiring and the chip with the

program and Bluetooth integration is approximately $250. OLED screens are new and upcoming

so they are generally going to be more expensive, but prices have been dropping drastically. In

2013, the price of a 55” OLED screen was 15,000, and over the span of one year into 2014,

dropped considerably to $3,500 retail. We believe that in several more years, we can produce the

screen or buy it for a very reasonable and cheap manufacturing price.

Final Specifications and Concepts

Throughout the course of the project, the design of our product continuously evolved. It

all started with conquering the outstanding problem of texting while driving, providing a safer

method to alleviate many distracted based accidents. The final specification of our design

includes a 20” OLED screen and the “Smart HUD” running program. The Smart HUD was

designed to be appealing, helpful, and incredibly simple to operate and understand. By default,

the program displays texts in the bottom left corner of the windshield, GPS in the middle left

windshield, and alerts in the top left corner. The unique aspect of our product is that we

implemented a color coding system based on traditional roadway symbols. The color coding

serves as an extra safety measure to ensure you have the fullest understanding of your

surroundings, especially while reading texts. All texts start out and are displayed as the neutral

color white. Depending on different roadway situations, the texts will change colors to alert you

in the situation you are in. While displaying texts in the windshield is safer to begin with, it

further alleviates the risk of being possibly too focused on reading texts. For example, if you are

approaching a stop sign or red light, the text will change the color red in order to warn you about

the oncoming signal. There are many colors integrated into our system that portray many

meanings. We used the color green to display directions, GPS; and was based off the color of

traditional road signs. The color orange is used to display alerts and warnings, such as

construction or heavy traffic incoming. The color blue is used to display services, such as

restaurants and pit stops. Lastly, yellow and red display the meaning of stop and slow down, in

response to red and yellow lights and stop and yield signs. The program is also fully

customizable and can be changed to fit the driver’s needs and desires at any time. For example,

you can change the UI interface to display the transparent texts where you want them to be

displayed or turn texts messages on and off as you please. Lastly, the Bluetooth integration has

the capability to let you respond to texts or calls via voice commands. Our product will be a

helpful contribution to our society, making people more connected and safer at the same time.

Conclusion

The Delphi project was a unique and fun insight on the overall engineering design

process incorporated into manufacturing a car part. Research was conducted, customer needs

were ascertained, and concept generation was carried out to design a part which engages the

driver to become safer and more connected. After much hard work and countless hours of critical

thinking and designing, the Delphi project was successfully completed. The goal of producing an

integrated car part was achieved, and met all of our customer’s requests. Conforming to our

customers was the absolute and main concern in this project. We crafted the part to allow the

driver to safely view texts allowing them to stay more connected. As long as the customer is

happy and the goal of the part was achieved, the project is viewed as an accomplishment. Lastly,

we made sure this part has longevity and alleviated any risks of failure. We used a sturdy

transparent glass screen display and reliable components to project the texts. Overall, the notion

of our on-screen text display is still young, but will soon become industrialized in all cars around

the world.
