DESIGN PROCESS

Identify a problem that exists.•Determine the root cause.•Gather information.•

1. Define a Problem

Present ideas in group.•Generate and record ideas.•Seek quantity not quality. •Keep the mind alert through rapidly paced sessions.•

2. Brainstorm

Analyze the reasons for the need, want, or problem.•Investigate who or what it is that is affected, and consider the need, want, or problem from their perspective.•Research any existing solutions, and identify why they are not adequate or appropriate.•Listen to clients to solve problems that they have discovered.•Perform market research to determine if a want or need exists and warrants the development of a design solution.•

3. Research and Generate Ideas

Identify the end user if the client is not. •Redefine the problem to the agreement of both client and engineer.•Identify what the solution must do, and the degree to which it will be pursued.•Identify the limitations within which the engineer must perform his/her duties.•Compile the information into a design brief.•

4. Identify Criteria and Specify Constraints

Initiate further development of brainstorming ideas with constraints and tradeoffs considered.•Explore alternative ideas based on further knowledge and technologies.•

5. Explore Possibilities

Create a decision-matrix to compare the attributes of the various ideas and analyze the trade-offs associated with each one.•Verify alignment between the idea selected and the criteria and constraints.•

6. Select an Approach

Develop detailed and annotated sketches.•Determine the type(s) of material from which the solution will be constructed.•Make computer models.•Create technical drawings from the computer model(s).•

7. Develop a Design Proposal

Make study models (scaled models or mock-ups).•Fabricate a functional prototype. •

8. Make a Model or Prototype

Test the prototype under controlled conditions.•Test the prototype under actual conditions.•Record the results.•Evaluate results to determine if problems exist and further work is needed.•

9. Test and Evaluate the Design using Specifications

Reassess the validity of the design criteria and make adjustments to the design brief, if necessary.•Work through the design process until the solution satisfies the design criteria. •Update the documentation of the final solution.•

10. Refine the Design

Determine Custom/Mass Production.•Consider packaging.•

11. Create or Make Solution

Present oral presentations with visual aids (computer generated slide show, models, prototype).•Develop written reports with appropriate graphic documentation (charts, graphs, technical drawings, renderings, etc.).•Market the Product.•Distribute.•

12. Communicate Processes and Results

Power Boat Project - DDP HONORS

Objective:

You are to research, design, build, and test a toy boat.

Directions:

Research existing boat styles and hull designs. Gather pictures in a Word document.1.Develop sketches of possible hull designs for your boat.2.In Inventor, design a part file of your hull.3.Slice that into several (about 5) ribs that can be used as profiles.4.Place those 5 profiles onto a drawing sheet and print them out.5.Transfer each profile rib to foam board.6.Build a mock-up of your boat hull using foam board and duct tape..7.Test it in the "Basin of Test" for stability, floatation, etc.---------------------------------------------------------------------------------------------------------

8.

Develop sketches of Deck & cabin designs.9.In Inventor, develop each of the parts that will make up the construction of your boat.10.Build a part file to represent your foam board.11.In an Assembly, build the boat as it would look in reality.12.In an Assembly, lay out each part onto the foam board model.13.Construct the cabin and paddle out of foam board. Attach all parts (including 3D printed hull) together using hot glue.

14.

Race your boat in “The trough of Death!”15.

Following through the 12-step design process, complete the following:

Parameters:The Hull of your boat should fit within this range:

SIZE constraints:Bow to Stern: 5” – 7 “Beam width: 3” – 5”Total Height: 1.5” – 2.5”

Hull wall thickness: .0625min. - .125 max

DESIGN constraints:

The boat must race against other boats. 1.The boat must be stable enough to safely hold the components of the propulsion system. 2.The boat must reach the end of the challenge basin within a specified time frame.3.

Research , design, build and test a boat.

Height= bottom of the hull [the keel] to the top of the hull [deck] •Width [beam]= the widest point of the boat •Length= tip of the front [bow] to the center of the back [stern]•Draft= how far the boat’s hull will extend underneath the water•Freeboard= the distance between the deck of the boat and the level of the water•

*The cabin and deck should be designed/built to fit your final hull dimensions.*

Desktop Organizer

Briefing: In order to supplement next year’s line of products, Mr. Streit’s company intends to incorporate a new line of desktop organizers. Your job is to research and develop a new design for this intent. You must develop two design ideas to be included in your report at the end of the project. Construction of one of your organizers will be part of the project.

Technical Specifications: In order to be successful you must fulfill the following requirements:

Your design must hold at least 5 different desktop items in 5 different areas of the organizer.○

The entire design and construction must be accomplished from one 12 inch by 12 inch by 3/16 sheet of foam core board.

○

Your report must encompass all of the steps in the design process. ○

3D modelsAssembly modelsDrawings w/dimensions and any necessary viewsAll necessary notes for construction with diagrams (use Word or PPT).A flat pattern for production purposes.

Your development stage should include:○

Title Page One page to highlight each step of the design process

Models□Explosions□Drawings□Prototype (Digital Picture)□Problems encountered/Design changes□

Pictures and Screen captures of the following:

Assembly instructionsOf course these are not the only things that can be included in your report. Include any information that you feel can help explain your design.

Report: Your final report should be in the form of a MS Word report to include the following topics:
