Week 14: Design Specification

Design Specification is a set of documented requirement that provide the product design team with the information they need to build out new features or functionality of a product. Good design specification should answer the following question:

-What are we building?

-What should the build achieve?

-How do we measure success?

Type of specification:

- Material specification

- Functional/Performance specifications 

- Standard specification

- Test standard

Below is my group Design Specification

Brief description

A coffee maker that hopefully provides better tasting coffee more catered to teenagers' taste

Expressing our love for coffee so you dun have to and have time to wiggle your toes


Function- To make high quality coffee because the coffee we have now taste like toes

Prototyping

A prototype is a simple experimental model of the proposed product to check how well it matches what users want through the feedback to help guide development.

It allows designer to:
-Have a solid foundation from which to ideate towards improvements—giving all stakeholders a clear picture of the potential benefits, risks and costs associated with where a prototype might lead. 
-Adapt to changes early thereby avoiding commitment to a single, falsely-ideal version and later incurring heavy costs due to oversights. 
-Show the design to the users to gather feedback to help pinpoint which elements/variants work best and whether an overhaul is required.

Fabrication Process

Our Prototype consist of 3 component, the base, the top, and the backing. In the first week of prototyping, we created this 3 component.

In the second week, we work on the top component of the prototype and our mechanism which is a lever.

Fitting a pringles can into the top hole which act as a container. However, pringles can is too tall hence...
