Part I – Design
Foldable Stair Climbing Cart
Design a Climbing Cart that can be used for easily transporting groceries, laundry, books etc… Devise a mechanism of motion that can tackle obstacles, stairs, curbs, slopes and uneven terrain. It should be foldable to a maximum of 5 in. depth for easy storage. Weight should not exceed 15 lb., while maintaining a weight capacity of 100 lb. The size of the cart should accommodate moving of medium-sized household items. Customers prefer the product to have a comfortable handle, and to be quick and easy to assemble.

Form teams and work on producing the following project components:
- AprototypeThemodel cannotbelessthan25%oftheoriginalsize.
The proof of concept should be shown through a physically made prototype/ model. Submission of the prototypes/ models.
- A written report. Each report shouldinclude:
- Table of contents, showing sections withheadings;
- Introduction outlining the scope of yourproject.
- Discussion/ procedure, that reflects understanding of the design methodology. Discuss the problem formulation, objectives, objective tree, PCC chart, constraints, function- means tree, QFD chart and drawings. Also include requirements (specifications), metrics and a conceptual design with an alternatives and morphological chart followed by a detaileddesign(costs,materialsandanalysisofdesign).Projectplanningandtimelineshould be included. Discussions should address the ethical and environmental issues.
- Conclusion summarizing thereport.
- Technical drawings using a CAD tool should be printed andattached.
