Toy Design Project
Proposal Due: Tuesday 08/01
Final Project Deliverables Due: Thursday 08/17
The goal of this project is to conceptualize and model an original toy design targeting children ages 8 and under. This project is an opportunity to exercise your creativity and to further explore the use of SolidWorks as a design tool. The emphasis of this project is on the proper consideration of design intent in building your part and assembly models. Ambitious and creative projects are encouraged and will be rewarded with generous grading (Caution – do not get in over your head!). We will form teams of 3-4 students to complete this project.
Your toy design should conform to the following specifications:
- Your toy must consist of at least 3 interlocking parts. Remember, any object that would be assembled from fabricated parts in a factory or at home is an assembly and should be modeled as such. Repeated uses of the same part do not count in the part total. It is okay if assembly would require adult assistance.
- The total volume of material in your complete assembly must not exceed 1 cubic inch.
- The parts for the assembly must be capable of being organized within a 4 inch cube.
- Your design must be original. You may want to visit a toy store to get inspiration, but your design concept should not be an exact copy of an existing toy.
- Safe for use by children 8 and under. You may specify a lower age limit if you wish.
- Consider all the possible uses of the toy. It will probably find its way to the child’s mouth no matter what it is, so the toy and its parts should be large enough to avoid choking hazard or you should specify a lower age limit.
- Avoid any sharp features that could cause injury.
- Durable for use by children 8 and under. Again, consider all the possible uses.
- Part modeling complexity/difficulty must be consistent with current homework assignments. Specifically, you should include some of the advanced features (sweeps, lofts, and/or shell) from Chapter 4 in your part modeling.
Project Requirements and Grading Breakdown
Design Proposal (20 points)
- (10 pts) At least one pictorial sketch (on isometric paper or white paper) of your design concept. You may need more than one sketch to fully communicate your idea. Use as many sketches as it takes. You might want to use colored shading, especially if color is important to your design.
- (10 pts) Two to three paragraphs (typed) explaining your design concept and how it meets the specifications listed above. Remember to describe how you think children will play with your toy. You may also want to describe how your toy would be marketed.
Part and Assembly Models (30 points)
- (30 pts) Submit a zip archive of your part and assembly files to the Toy Project Dropbox by the 3-D print deadline. Make sure all features/sketches in all models are fully defined according to YOUR design intent.
Final Project Deliverables (50 points)
- Make revisions (if you want) to your design after evaluating your prototype.
- (20 pts) Produce a written description and screen captures (shift-Print Screen) of SolidWorks sketches or intermediate feature steps that explain the sequence and design of features used to construct your part models. Highlight how you have incorporated design intent into your part models by explaining what constraints (dimensions and relations) you set and why you set them. The primary considerations that should be discussed in this write-up include:
- Describing how specific features on mating parts are constrained for ease of edits throughout the assembly.
- Identifying key dimensions that relate to the ergonomics and function of the toy and explaining how they are driving dimensions in the part models.
- Identifying key dimensions and/or sketch relations that drive the aesthetics of the toy and explaining how they control edits of the part models.
- Description of why key assembly relationships are consistent with the function/operation of the toy.
- Explaining how the overall sequence of features and the specific features/sketches that are used incorporate the design intent that you explain for a, b, and c.
Note: This write-up SHOULD NOT be a step-by-step guide of how to build a SolidWorks model of your toy. It should only focus on the key sketches, features, and assembly relationships that are relevant to the design intent.
- (5 pts) Submit hardcopy printout(s) of one or more three-dimensional views of the specific part model that include advanced features. Annotate (by hand) the printouts to show the advanced features in cases where they are not obvious.
- (10 pts) Submit hardcopy printout(s) of one or more three-dimensional views of your completed assembly. Use color to show the different parts in the assembly and create an exciting looking toy. These views should be printed in color (you can use the plotter in SHK 226 if you wish).
- (5 pts) Submit hardcopy printout(s) of one or more exploded views of your assembly that clearly shows all the parts involved and how they fit together. This should be a suitable graphic to provide as assembly instructions for your toy. These views should be printed in color (you can use the plotter in SHK 226 if you wish).
- (10 pts) Overall quality and creativity of the entire project.
Submit all final project deliverables together (stapled in order – no folders please) by the due date.
