Customer Requirements and Product selection Need Addressed: • According to OSHA: • 85 forklift fatalities per year • 34,900 serious injuries per year • Safety at Blind Corners Target audience: • Companies with large scale factories and warehouses Selection: • Began with brainstorming • Took best ideas and chose what was most feasible and could make the biggest impact
Conceptual Design Dual Function: • A motion sensor that detects motion of • Vehicles at blind corners • Forklifts in industrial settings Physical Design: • Small sensor mounted at corners • Alerts people to something they can’t see Refinements: • Size - optimize space usage in industrial setting • Circuit design - creating a circuit that actually works • Focus on industrial settings
Actual design • Utilizes an infrared motion sensor relaying to an LED • Can be time synchronized with road speed limits to give an accurate warning to pedestrians and drivers • Sensor and LED relayed through a cheap and cost effective circuit
Feedback • Worker who has Operated a Forklift: • “It will alert everyone that there will be equipment moving and to stay out of the way. It would be ideal in warehouses and places like Home Depot.” • TDOT Engineer (Road Applications): • “Focus on areas where there is a high volume of fatal/significant wrecks. He advised that in order to sell our design we need to focus on these crash sights and show that by using our product, we could drastically decrease the loss of life.”
Time of Design and Cost of Model • Total Time for Design: • 60 Hours • Model: • Design: • PIR Motion Sensor • RedBoard • Cost: • RedBoard - $20.00 • LED - $0.24 per light • PIR Sensor - $1.67 per sensor • Wires - $0.80 • Wood - $0.78 per unit • Total - $23.49
Cost Estimate of Final Product • Estimated Cost: • Single Unit: $27.00 • 1000 Units: $9082 • Cost per Unit: $9.08 • Retail Price: $19.99 • Compare: • Industrial Mirror: $35-$60
Summary and Conclusion • Improving Safety: • Address the safety issues of forklifts • Provide better option than mirrors • Future Applications: • Expand to vehicles and roads • Parking garages and blind corners
