Engineering Design and Research Welcome to ENGINEERING DESIGN

Engineering Design and Research Welcome to ENGINEERING DESIGN AND RESEARCH. Upon entering the class please have a seat towards front of the class (Do not move chairs from one table to another).

to understand apply knowledge / skills required to create & transform ideas + concepts into a product that satisfies specific requirements. Students will experience design engineering in the creation, synthesis, iteration, and presentation of design solutions. This course will maintain a focus on: the history (and future) of engineering, how engineers apply mathematical, scientific, creative, and technical knowledge / skills in creation (refinement) of technical products/systems. A key approach will be the employment of a sequential, and iterative design and development

. The following major ‘topics’ or ‘chapters’ will be included to organize instruction of appropriate standards and benchmarks and reflect contemporary engineering industry practices: • Principles of Design • Engineering Resources • Engineering Design Process • Project Management

Text: Engineering Your Future Chapter – Engineering Design pp. 351 – 377 Answer handout questions then complete ‘Reverse Engineering Models’ assignment (described at bottom of handout). Be sure to take notes (sketch or written) documenting method of taking object apart so object can be re-assembled.

Before we continue our ‘reverse engineering’ asignmnet it is important to spend a little time on General Lab Safety - Upon entering class immediately have a seat and complete daily drill. - Never touch class tools equipment without teacher permission. - Only use equipment that teacher has demonstrated. - Use tools / equipment as directed and for purpose tool is intended. - If you have a question on how to use equipment, tools or how to do a procedure ask for teacher instruction. - Report all damaged/ broken/ malfunctioning equipment to teacher.

How many of the following rules did we get? • When working around machines with moving and/or spinning parts be sure to secure dangling jewelry, long hair, loose clothing, and remove accessories that might get caught. • When working with equipment focus on what you are doing. Do not speak to people operating machines. • Stay out of machines ‘Safety Zone’ (3 foot perimeter) if you are not directly involved in operation. • Immediately report all accidents/ injuries to

A few more important safety items • Tools for cutting should be sharp…Dull tools cause injuries • Wear safety glasses • Return tools and equipment to proper location as soon as you are finished using it! • Do not carry long stock by balancing it in center. • Wear an apron to protect / secure clothing • Do not put sharp tools or hot items near neighbors, face, or handle carelessly. • Do not use electrical tools or items in such a

Engineering Design Research L 2 Complete ‘Reverse Engineering Models’ assignment (described at bottom of chapter 13 handout). Be sure to re-assemble model with all parts in correct location. Accurately sketch a diagram of all of the parts and illustrate how they fit together to make the device operate. List at least three ways you feel the device could be improved.

Engineering Design and Research L 3 – Safety Review Safety Video Safety test • OBJECTIVE : Safety • DRILL: Identify three important safety rules to follow while working in the Technology Lab
