CONCEIVING AND ENGINEERING SYSTEMS

Idea

Make a bicycle turn signal out of LEDs that can be mounted on almost any bike and that gives the user control of the turn signal without losing the ability to also use there arm as a turn signal.

Problem Statement

· Each year, more than 500,000 people go to the emergency room for bicycle injuries in the USA. More than 700 people die from those injuries.

· Children 15 years and younger are the biggest risk.

· Bicycle injuries and deaths cost $8 billion each year.

·Adolescents/Young people(ages 15-24) and adults aged 45 and older have the highest death rates.

·Males are more likely to get injured than females.

·Most of all bicycle deaths happen in urban areas and non-intersection areas.

Setting System Goals and Requirements

Market/Customer needs

Competitive Bike Riders
Leisurely Bike Riders
Supply a proactive safety mechanism to a market that lends to $8 billion in annual cost resulting from injury and death. By implementing an easily recognizable safety system, it is not only the biker community that benefits, but automobile operators, and local government- with benefits trickling down to taxpayers as well.

Factors that set the context of the requirements

Customer Needs (MT)
Cost of Materials (MT)
Time/Duration of Project (MT)
Aesthetics (MT)
Practicality (MT)
Marketability (MT)
Available Resources (MT)

Enterprise goals and capabilities

Simplicity
Cost effectiveness
Employ a product that can easily be integrated in any enterprise scenario that would call for such an item.

Competitors and benchmarking information

Ethical, social, environmental, legal and regulatory influences

System goals and requirements

Initial target goals (based on needs, opportunities and other influences)

System performance metrics

Defining Function, Concept and Architecture

Necessary system functions

Provide luminance that projects a minimum of 10ft
components mounted upon a surface area visible from a minimum of 10ft away
LED placement distinguishable as arrows
Ability to indicate movement of two directions (left and right)

System concepts

Trade-offs among concepts

High level architectural form and structure

The decomposition of form into subsystems, assignment of functions to subsystems, and definition of interfaces

Modeling of System and Ensuring Goals Can Be Met

Appropriate models of technical performance

The plan of implementation and operations

Trade-offs among various goals and functions

Development Project Management

Project cost and schedule

Additional Costs (not originally provided by class)
$7.50 - set of LED Holders
$7.95 - 25 Pack of LED
TBD - Cost of 3D printed housing

Estimation and allocation of resources

Risks and alternatives

Users could depend on using general hand signals
Risk of limited sight range
