Concept Refinement
Home > Assignments > Concept refinement

Use what you have learned from the sketch models to decide (as a team) which of your concepts will now be detailed. If thee are other teams working on a similar concept, please coordinate so that each team's work will bring a unique viewpoint. Also, you may proceed with more than one item, but your team's scope should be restricted only to ideas that you expect to carry through to final prototypes.

At this stage, the goal is to proceed with detailed design. The result will be a much more complete definition of both form and operation, from which you will build your final prototype. You should also obtain practice in digital modeling techniques, using a tool that is appropriate for the issue that you are trying to resolve (e.g., illustrator, solidworks, photoshop, or other digital modeling tools) and apply some of the thinking about design details (from, color, and graphics, etc.) that we will be discussing in class.

All work should be coordinated with your team to move the project forward, but your design work will be graded individually. You may want to look at deliverables from some previous teams (example 1, example 2, example 3—a product that was available the coop for a number of years, example 4, example 5).

To start
Make sure that your team has a clear direction to pursue.

Your team will need to submit a complete exploded assembly drawing(s). You will also need to indicate what aspect of the system your individual work is developing.

Team members may work on: detailed form variations of the concept; different aspects of the artifact (e.g., user interface design, user interaction, software design, circuit design, mechanical design); or user instructions. Do what is needed to develop and detail the concept.

Keep in mind that the next step will be to prototype a realistic, detailed product based on your concept.

Develop detailed design variations using sketching, solid modeling, and engineering analysis techniques as appropriate. Be sure to refine both the form/interface and the operation of the concept. You may also need to make additional sketch models and perform tests during this process. Be sure to keep the client requirements in mind. While designing, be careful not to overlook issues such as user instructions/ease of use, safety, reliability, and packaging/shelf presence.

Once you have finalized your detail design work, prepare a digital model of the part(s) you have worked on.

The models of your parts should also be used by the team to create an overall assembly for the complete 'system design'.

Solidworks is available for download (certificates required), but the license requires that you are on-line with an MIT 18. IP address. Solidworks also comes with a number of good tutorials and, if there is interest, a tutorial for the class can be arranged as well. If you do not have illustrator or photoshop, you can use a one month trial of adobe creative cloud.

Prepare your submission
Prepare images of your digital models in a web page or series of web pages. Be sure to include detailed explanations or instructions so that the work can be understood. Also, please make it clear what aspect of the overall concept you are addressing (you may want to link to the team's system assembly submission).

Your team must also prepare an overall system/concept web-page that includes a complete, system assembly and what the system will look like. It should include an explanation of the overall design's operation and a description of how the user is expected to interact with/experience the device. Details of sub-system operation should be explained in the individual work pages.

Please see the submission instructions for additional details.
