Mechanical Engineering Studies Help Required

08/14/2016 6:08 PM

For my Level 6, I have do a technical design report, and the instructions are: " For this written assessment task you are required to write a technical design report in which you present a design problem, describe 2-3 possible solutions (in words and sketches), and then recommend one of these solutions. " As I am new to this field, I don't have much knowledge, I was thinking of doing a vibration on a drive motor of a Pre-Breaker, would that be a design problem? if not what topics would you guys recommend?

Thanks in advance

So, you have identified a problem, mechanical vibration.

Now, study the causes of the vibration and how you might reduce the vibration transmitted into the machine, and into the surrounding environment.

Loosening of fasteners, mounts, wiring, etc.

Noise is a problem caused by vibration transmitted through the air and even the human body.

Possible solutions: damping vibration with mounts, either rubber or some other material.

Electronic vibration cancellation? Look at active automotive suspensions and motor mounts.

Air bearings?

I have just been informed that my topic choice is not suitable, would you have any other ideas that could work as a design problem in engineering?

If you can find out what topic choices are acceptable it will reduce the amount of guessing we have to do.

It is up to you to determine an acceptable subject. It is, after all, your assignment.

I have had a few topic that was declined by my tutor as all my ideas he said is not a design problem, it has to be a design problem within engineering. a previous student had done "design improvements for bench vice handles."

I have thought about the idea that might work, a frame has to build within a room that is flammable, therefore solutions could be either to use bolts to join the frame or put up temporarily fire resistant sheets. however i wouldnt think that, that is a good enough topic. thats why i came here for help

You might follow this guy's lead, and go out into the world and look for problems that could be solved...

I hope level 6 in your engineering education is the entry level class. You don't seem to have a clear understanding of how to approach and study an engineering problem to reach a possible solution.

Considering I am new to the whole engineering field, I did expect some struggle yeah. However, I am still trying my best. So a negative comment isn't what I am looking for. However, thank you for your concern

An example of a design problem:

Problem: Apple iPhones need for frequent recharging.

Potential causes: Battery too small/low power, too much heat generated/too little dissipated, software uses too much power, antenna too small, too many programs running in the background or user error.

Solutions: Source a battery with more power from the same size. More efficient material for the heat sinks. Streamline software. Design a better antenna. Reduce number of programs running in the background. Tutorials to teach people how to make the battery last longer - don't run so many things at one time, close unused aps, etc.

Recommendation: Create a program to monitor battery usage. When too much power is being used, run an analysis to find aps or programs that can be shut down. Run a tutorial for the user to let them know what they can do to lower the power usage.

I don't know how serious the design problem presented to you.

Is it a group assignment?

We did one similar in college 30 years ago. I'll share with you what I have learned.

Develop a Fishbone Diagram to address and define the problem.

Then, with something to hang your hat on it will make it easier to mitigate more quantitative solutions and the consequences to the solutions.

I used the Fishbone Diagram and actually made it super easy :)

Wow, that brings back some memories. Fishbone Diagram! We used these when I was in my MBA program. Like you pointed out, they're great when working in a group.
