Hi,

I am a teaching assistant in Middle East Technical University Mechanical Engineering Department and I was responsible for the Final Projects of senior years for 6 semester.

The suggestions that I will give here is not specifically about your shoe polisher, but about how you need to approach the design process.

First of all, trying to get concept suggestions is not an effective idea because we are not thinking about that project as much as you or your teammates do. Other people (than your teammates) will try to understand your problem, they will think about it for 5 minutes (at max) and give a suggestion or not. But you are thinking about it the whole day or week or semester. So we can't "create" better concepts than yours in 5 minutes. But there is a solution of course.

If you are working as a team (and I always suggest to work as teams for engineers), you need to do a brainstorming session with your teammates to create many many concepts. There are many resources on the internet about brainstrorming but don't waste too much time researching that. It will easily turn into procrastineering. Just remember that there is no "NO" in brainstorming. If somebody suggest something, you can't say "No it's not feasible" you can only say "in addition to that, we can modify your suggestion like this and we also solve the blah blah problem". The reason for this is, if you say "no", you block a whole branch of ideas. Let the tree grow, when it stops growing, then you can cut some branches. Now you can say "this idea is so futuristic, we can't achieve this" or "this would be extremely expensive and it appears that we can't find a way to make it cheaper". But be careful! You can only cut the "extreme" branches. They must be "Extremely expensive" like using titanium for chasis or "so futuristic" that it needs teleportation to work. The others should stay.

Then you need to know what you want. Or what the customer wants. Or what the boss wants. They must have some criterias. Like "It must be cheap", "it shouldn't take much power", "it should clean 2 shoes at the same time" or maybe some special necessities like "it can't contain electrical motors (spark danger maybe)".
The last one is a MUST. You must obey this. If any of your concepts use electrical motors for example, you must try to modify those concepts and if you can't, they must go.

The other ones are the measurable criterias. And you need to assign points to them like "how important are they". For example if you are building this for a luxury hotel chain like Hilton, making it cheap doesn't have a big importance. But if they want it to run on battery (not AC), power consumption has a very big importance.
Then you need to compare the concepts. For example a concept may be cheaper but needs more power, then it can't have much points because of the "importance coefficients/multipliers).

And there may be some "Good to Have"s. These are like "if it can do this it would be great but not a must actually, just it would be good to have". These are bonuses. It is up to you as engineer to consider these when you are comparing your concepts. Because sometimes customers want some additions that would make the whole system unreliable. For example, does your shoe polisher really have to have an iPod input?

After the comparison, select the top 3-4 concepts and make one your "Best Concept" and make another your "Second Best Concept". The second one is your backup plan actually.

Then you can show those concepts to us and we can make suggestions like little modifications or additions or better: subtractions.
