* 产品设计流程——吸尘器案例分析 Regarding the research, other than finding out how a vac works, I went to various stores to ask the salesman what customers look for and what they complain about. I did that in both Asia( over the break) and in the US. Also, as I was hunting for parts, I learnt more too.  My initial reason to do such a design is because I hear complains from Asian housewives complaining the heaviness of up rights, and American housewives complaining how weak canisters are. The problem is, none of them actually have used both kind of vacuum cleaner to make those statements! It really all comes down to impression and hear-say. So I want to create something that not only works like either, but also performs like either. I figured that the user probably will stick to just one mode after trying it out, but at least that gives them the chance to really find out which mode they prefer. I did this last semester. It was a blast for me. So let me explain it a bit. This vacuum cleaner can transform from a canister mode to upright mode as a single unit. There is a vacuum cleaner that was released recently( cannot remember the brand and I cant seem to find it online) that transforms from upright to canister. Well, that is not transformation, because it simply splits into two units! You will be paying for 2 units instead, and while using it as canister vac, the other part will just sit there being useless. Therefore, my Bean Vac acts as one unit, and transforms as one unit. Its really a 2 in 1 vac. The Bean name came from nothing but the shape of a bean which inspired the general form. There was a story that led to this but I dont think its worth mentioning here. So I went through a couple of working( articulating) mockups with insulating foam, got 2 of my friends of different percentiles to test them out, and also to prove that the pivoting handle design works better than the conventional ones. Later, a Rhino mock up model was made and I used that as a general temp
