ME403: Student Design Project

Unit 2: Design Considerations and Principles   To properly engage in a design, you must be able to understand the various principles and considerations – beyond the basic solution of a problem – that should factor into your decision making.  For example, a cost analysis of the product or process must be conducted to make sure that it is economically and commercially viable.  You must also examine the impact your design will have on users, society, and the environment.  You should be aware of the legal and ethical issues surrounding your design, including its potential for intellectual infringement (i.e., copyright and trademark violations) at local and global levels.
