Idea edit

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 edit

· 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 edit

Market/Customer needs edit

  • 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 edit

  • 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 edit
  • 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 edit
Ethical, social, environmental, legal and regulatory influences edit

System goals and requirements edit

Initial target goals (based on needs, opportunities and other influences) edit
System performance metrics edit

Defining Function, Concept and Architecture edit

Necessary system functions edit

  • 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 edit

Trade-offs among concepts edit

High level architectural form and structure edit

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

Modeling of System and Ensuring Goals Can Be Met edit

Appropriate models of technical performance edit

The plan of implementation and operations edit

Trade-offs among various goals and functions edit

Development Project Management edit

Project cost and schedule edit

  • 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 edit

Risks and alternatives edit

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