MEM201 Final Project Requirements What to do? 1. Identify an issue with an existing product/design or produce a new product/design to solve a problem. 2. Design a solution to the identified problem. Solution must be an assembly of at least three (3) non-standard parts. 3. Design parts and model all parts in ProE 4. Create an assembly of the parts in ProE 5. Create detail drawings in ProE or AutoCAD (ACIS *.sat, ACISIN) of non-standard parts and assembly drawing of final assembly. 6. Write report to discuss design feasibility, ergonomics, manufacturing and cost. This can be done before modeling. What to submit? You can use the following template as a guide. You are required to address the following two items (write-up and working drawings), but are not required to use the following template (pages 2,3). 1. Write-up to include: Design feasibility (why/usefulness of your design), Ergonomic study of the design (comfort-ness), Discussion on the manufacturability and cost 2. Working Drawings: A set of working drawings consisting of an assembly drawing of the design including Bill of Materials assembly drawing of the design, 3-views (top, front and side) for all customized designed parts How to submit? Due Date: 12/10/12 6:00 pm Submit to: Hard Copy: Randell 115 (MEM Office) will be a box to collect submissions Soft Copy: Drexel Learn

GRADING RUBRIC Point Value Section 5 Design Feasibility Present an observation you have made where a new product would be beneficial or an existing product could be re-engineered. 5 Design Feasibility Introduce your product or imporvements 10 Design Feasibility How innovative is the design e.g. new material for an existing design (1/10) vs. new product with new design (10/10) 4 Ergonomics Address how your part will be handled, maintained, repaired, customized for fit, … 3 Manufacturing Cost Estimate of raw material cost 3 Manufacturing Cost Introduce possible manufacturing methods 5 Solid Model Screen shot of solid model of your parts or assembly 10 Assembly Drawing Drawing of complete assembly with all standard and non-standard parts 5 Bill of Materials List of all standard and non-standard parts, including assembly number, description, material and quantity. 5 Bill of Materials All items in the assembly drawing are annotated by their assembly number. 30 Detail Drawings One for each of the non-standard part. Minimum of three. 5 Detail Drawings Complete dimensioning, following proper guidelines. 5 Detail Drawings Tolerances 5 Model Complexity e.g. parts are all single extrusions or cubes/blocks (1/5) vs. parts have multiple extrusions/subtractions, holes, revolves, … (5/5) 100 TOTAL MEM201 Winter 2014 Final Report Page 2

Table of Content 1 Measurable Goals ................................................................................................................ 3 2 Design Feasibility ................................................................................................................. 3 3 Ergonomics ........................................................................................................................... 3 4 Manufacturability and Cost ................................................................................................... 3 5 Detail Drawings .................................................................................................................... 3 6 Working Drawings ................................................................................................................. 4 1 Purpose: Briefly describe a problem you want to address. Present the requirements of your design; low cost, low weight, portable, more robust, …) Present your engineering solution in the design feasibility section. 2 Design Feasibility Purpose: Design feasibility (why/usefulness of your design) feasibility (why/usefulness of your design). Relate your design choices (materials, shape of your part, tolerances) to the design requirements identified in the engineering objectives. 3 Ergonomics Purpose: How will a person interact with your product? Consider some of the following: assembly, maintenance, handling, portability, can be used by any age, …. 4 Manufacturability and Cost Purpose: Identify materials, manufacturing techniques, and cost estimate. Include rough monetary estimates to produce for full credit. McMaster Carr is a commonly used supplier of standard parts. It is a valuable resource for finding suitable parts. Most product specifications also include CAD drawings for you to use for modeling. Website: http://www.mcmaster.com/ 5 Detail Drawings Include a complete detail drawing for all non-standard parts. All parts presented on their own drawing with three orthographic views (top, front, right) with dimensions and tolerance. Use title block. Homework problem 12-2 can be used as an guide. Print each drawing and include each as a full page. 6 Assembly Drawings Include a working drawing of the assembly. Rules of thumb for creating assembly drawings are as follows: single isometric view of assembly as a solid model. Include a parts list with item numbers called out on assembly drawing. Homework problem 12-2 can be used as an guide. Print assembly drawing and include as a full page. MEM201 Winter 2014 Final Report Page 4
