 Create device to make surrey accessible to people in wheelchairs  Find the most cost-effective solution  Device should be simple to use

(More specific details in handout)  Customer Requirements  Minimize additional turning resistance  Mount on two different surreys  Install/Remove the device quickly  No seating modification  Cost less than $500

 Additional Requirements ◦ Minimize:  Weight  Length  Or exclude frame modification ◦ Unloading mechanism (ramp) travels with surrey

 Rear Mounted Concepts  Allow surrey to travel over uneven terrain while preventing failure at device mounting locations (see chalkboard).

 November ◦ Present design approach ◦ Based on feedback, focus design ◦ Materials Research

 December ◦ Detailed Design ◦ Stress Analysis ◦ Research Manufacturing Costs (i.e. welding)

 January ◦ Construct Wooden Prototype ◦ Test and Refine Prototype

 February ◦ Detailed Design Review ◦ Fabrication and Testing  Early May ◦ Presentation on final product

 Aluminum - $590 Total ◦ Parts - $440 ◦ Labor - $150  Advantages ◦ Lightweight ◦ No corrosion  Disadvantages ◦ Cost ◦ Manufacturing ◦ More susceptible to fatigue  Steel -$355 Total ◦ Parts- $355  Advantages ◦ Cost ◦ Manufacturability ◦ Adaptability  Disadvantages ◦ Weight ◦ Corrosion
