CONCEIVING AND ENGINEERING SYSTEMS
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
