CONCEIVING AND ENGINEERING SYSTEMS
Idea
[edit | edit source]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 | edit source]· 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 | edit source]Market/Customer needs
[edit | edit source]- 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 | edit source]- 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 | edit source]- 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 | edit source]Ethical, social, environmental, legal and regulatory influences
[edit | edit source]System goals and requirements
[edit | edit source]Initial target goals (based on needs, opportunities and other influences)
[edit | edit source]System performance metrics
[edit | edit source]Defining Function, Concept and Architecture
[edit | edit source]Necessary system functions
[edit | edit source]- 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 | edit source]Trade-offs among concepts
[edit | edit source]High level architectural form and structure
[edit | edit source]The decomposition of form into subsystems, assignment of functions to subsystems, and definition of interfaces
[edit | edit source]Modeling of System and Ensuring Goals Can Be Met
[edit | edit source]Appropriate models of technical performance
[edit | edit source]The plan of implementation and operations
[edit | edit source]Trade-offs among various goals and functions
[edit | edit source]Development Project Management
[edit | edit source]Project cost and schedule
[edit | edit source]- 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 | edit source]Risks and alternatives
[edit | edit source]- Users could depend on using general hand signals
- Risk of limited sight range
