Building a doghouse like a skyscraper

It doesn’t take any special skills to build a simple dog house (just collect some wood, nail the pieces together; measuring and cutting is optional; the customer (your dog) will be happy with anything),

Building a skyscraper requires serious planning, financing, many calculations, many meetings and presentations, proper documentation, purchasing the correct materials, scheduling, and so on; it is very expensive and nearly impossible to fix if a mistake is made; it must be engineered from the start!

The goal in this course is not just to build something, but to engineer a product prototype - to design and build a “doghouse” as though it’s a skyscraper.

Design, build and test a prototype product

Engineer-level workDesigning mechanisms and mechanical components, strength and materials analysis, circuit and sensor design, development of software and control system algorithms, organizing and managing schedules, budgets, and presentations, designing test procedures, etc……

Technician-level workProduction of CAD drawings from designs, fabrication of parts, assembling electronic circuits, writing code, etc.

Contribution at each level is important

Each student lead the engineering of some part of the project.

DOCUMENTATION

Technical Notebook Primary Project Record

Permanently bound technical notebook required

Provides a record of the design and engineering work by an individual.

Technical notebook should be used to record…meeting notes, concept sketches, analytical calculations, contact information, test conditions and results, design diagrams, random ideas,...

All written and hand-drawn information should be written into this one central notebook.

When possible computer generated information (subroutines, small CAD drawings, budget tables, work schedules, xeroxed research information, etc.) should also be included

ELM4701 Electromechanical Projects 88/23/2011

Electronic FilesA file system on a computer drive organized into working areas and containing: …electronic drawings, files for software development, spreadsheet files (schedules, budgets, etc., presentation (source) files, digital photos, web site, etc.

Serves as a permanent archive of the project

Structured in an organized and logical way (directories and subdirectories) and documented in a ‘README.DOC” file.

Other RecordsA three-ring binder and paper folder system may be used to store and organize other project records…purchase orders, research articles, etc.

BrainstormingGuidelines [from Tools and Tactics of Design, P.G. Dominick et al., (John Wiley, 2001)

1 Criticism is Ruled Out• Generate as many ideas as possible in the allotted time• Do not critique ideas, generate them• No idea should be squelched no idea is too silly or impractical

2 Creative and Imaginative Thinking is Encouraged• Free-wheeling and wild ideas are welcomed• “Think outside of the box”• A solution may evolve from an side comment or a simple idea that is initially perceived as a

joke

3 Quantity is the Metric• Success is measured by the quantity of ides generated (not the quality)• The goal is to generate promising ideas that will need much further refinement

4 Combining and Extending is Good• Interaction between those in the session is good• Suggestions by one may stimulate formation of ideas by another• The extension of one idea or a combination of two or more can lead to idea refinement and

improvement

Mini-Project: Brainstorming and Team Forming

Rules of Engagement

• Everyone has the problem statement

• For a fixed period of time (15 minutes) people make suggestions of solutions and write them all down (on the blackboard). No suggestion should be discussed other than to clarify its description; no comments should be made about the quality or effectiveness of the suggestion.

• Dozens of suggestions and variants should be possible and the process continues until we fill the board (the vast number of suggestions usually convinces everyone that something worthwhile has occurred).

• Take a break (5 minutes).

• Everyone returns to refine the suggestions and eliminate some; it will be possible to start grouping the remaining ones into similar groupings and eventually get the number down to 3 or 4 types.

• At this point let individuals or groups request to work on a solution of their choice.
