1. Presented by: Angela Smith ∙ Dennis Hugo ∙ Kevin Messer Marie Barraclough and Austin Hanson

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

3. (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

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

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

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

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

9.  January ◦ Construct Wooden Prototype ◦ Test and Refine Prototype

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

11.  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
