Phase 0: Planning
Mission Statement
Product Description
The ARC of Monroe County has requested a communication board for one of its consumers who has limited
verbal and spelling capabilities. This is a revision of a project completed during the 2006/2007 academic year
that demonstrated the fundamental operation of a battery powered, touch screen, and LCD display based
device. Based on feedback from the customer, the prototype needs to be refined to more closely meet the
actual customer requirements in terms of size, weight, durability, and operational characteristics.
Key Business Goals The primary business goals of this product are to
Improve the quality of life for an individual with speech/spelling disabilities by providing the ability to express
his/herself through a picture based communication boa
Create a product that can be utilized by all individuals with speech and spelling disabilities throughout the city
of Rochester, and possibly the whole state of NY, contributing in a positive way to the community.
Primary Market
The primary market for this beverage container is the ARC of Monroe County
Secondary Market
Secondary markets for this communication board include any individual with speech and/or spelling
disabilities, as well as children between the ages of 3 and 7.
Stakeholders
Stakeholders in the design of our product include the following:
The ultimate consumers
The ARC staff who interacts with the consumers regularly
The families/friends of the consumer
The visitors to any area in which the product is being used

Student will set constraints for the engineers to work around, apply knowledge regarding the manufacture of
systems to aid in the planning and development of the product and its subsystems, will help group design for the
customer.

Phase 1: Concept Development
Identify Customer Needs - Interviews
Primary Customer(s)
So far, multiple interviews have been conducted with the faculty guide Dr Phillips. The
overviews were both very detailed and the primary objectives emphasized were captured.
Lisa Drewski was interviewed on October 2nd, the needs were refined and quantified as a result
We remain in touch via email, and another meeting is tentative for Thursday Oct 18 th
Other Stakeholder(s)
The faculty guide to last year’s project: Dr Debartolo was interviewed on October 2nd as well.
She provided her insight regarding the positives and negatives of last years project, and will be
a very valuable resource as the project progresses.
Amy Feekes, the habilitation coordinator for Donna (the end consumer), has been conversed
with via email and telephone, and will hopefully be met with this Thursday.
Past Senior Design Team(s)
This project is a continuation of a project that was completed last year (P07001).
The team’s webpage on the edge website is currently available, as well as the engineering
logbooks used by the team during senior design I and II from last year.
The team’s final product is available for the team to use (benchmarking analysis, parts, etc)

Work Breakdown Structure
WEEK 1
• IE: Introduce project, conduct benchmarking session,
answer any initial questions from team members
Ensure that the team knows what the objective
and scope of the project is by the end of the
meeting
• ME1, ME2, EE1,EE2, CE, ID: participate in
benchmarking activity, develop three ideas AND
three questions pertaining to the project and bring
for discussion the following week
EDGE™
Work Breakdown Structure
WEEK 2
•
•
•
•
•
•
•
Conduct follow up to week 1, adequately answer teams’ questions. If
necessary, set up a meeting with the team and customer.
Delegate/discuss the different existing positions for the group, assign.
Emphasize intuitiveness of HCI. Research ADA guidelines and existing
product patents.
ME1: Research material to be used for the custom enclosure, obtain a list of
at least three materials. Brainstorm ways to fabricate.
ME2: Research material to be used for the custom enclosure, obtain a list of
at least three materials. Brainstorm ways to fabricate.
EE1: Brainstorm sources of mobile power: focus on achieving 16 hrs of
continuous battery life. Record different sources and the specifications
associated with each option.
EE2: Re-familiarize self with assembly and C programming (if necessary).
Analyze what embedded hardware will be needed and record
CE: Analyze software used in last year’s project, brainstorm alternate
operating systems that can be implemented or changes that can be
made to last year’s software. (Faster is the key)
ID: Begin to develop constraints upon which engineers can work around.

•
•
•
•
IE: Observe and record team members’ findings, discuss as a team, focus
on narrowing down possibilities while keeping the needs of the customer in
mind. Begin to develop ergonomic constraints for ME’s to design around
ME1: Research wheel chair mounts, brainstorm three proposals to properly
mount board to user’s tray without inhibiting user’s lifestyle
ME2: Focus on the prototype of the custom enclosure, ensure it will satisfy
user requirements. Create a preliminary design for the interior fixture of the
product.
EE1: Determine possible battery chargers for the batteries researched last
week, obtain a rough estimate of the power required to run the system,
analyze the DC-DC converter/regulator for the product
EE2: focus on the input/output circuit design, begin planning how to program
the hardware
CE: Assist EE’s with finalizing the embedded hardware required to run the
product, brainstorm coding software that will be best for the product
ID: Assist ME’s with planning for materials and fabrication of enclosure,
with costs and consumer reaction in mind.

Grading Assessment
SD I
• Average expectations ( C )
Parameterized design of prototype system developed (proposed selection
of system hardware and software materials, software and hardware
engineering specifications) that COULD be implemented to evaluate
functionality and user interface.
• Above average expectations ( B )
Average expectations PLUS a PC based test system that demonstrates the
potential to be utilized by individual and ARS staff to evaluate optimal
configuration and promote interaction between customer and others.
Software and hardware designs (specs, flowcharts, drawings) complete, as
well as completed BOM. Prototype of final enclosure designed
• Excellent ( A )
Everything above PLUS the actual development of a computer platform
comprised of specified hardware and software components that CAN be
utilized with individual and ARC staff to evaluate optimal configuration and
interaction. Final concept design exists, all required deliverables submitted
on time
EDGE™
Potential Risks/Issues
• Designing/constructing the product under the
proposed budget of $1200
• Meeting all of the deliverables and developing a
product that the customer is happy with in 20
weeks - all customer needs attainable? (16 hrs
of battery life and a fixture)
• TEAM versatility
EDGE™
Future Plan
Where do you go from here?
From this point,
- I look forward to meeting with Dr Rickel to discuss the
addition of an industrial design student to becoming involved
in this project.
- I plan on refining the work breakdown structure as
necessary, as well as exploring tasks beyond week 3.
- John Bonzo has been suggested as a viable resource in the
construction of the custom enclosure, so I definitely have to
meet with him within the next week.
- I will contact Lisa to ensure that the final list of customer
needs are all correct.
