作者的意念和过程
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 can't 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. It's 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 don't think it's 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 template for my full scale physic

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.

总结下，工业设计就是一个对产品的使用、功能，甚至结构、材料的不断的思索过程，在产品的各个构成方面和元素上不停地思考，去找到一个恰当的平衡，这种思考的结果最终落实在产品的使用和形态上，在国内则被简单理解为外观的设计和装饰。两种不同的思维方式做出来的产品就是西施与东施的区别，只仿其型，不知其神，没有思考的设计过程=一个浅薄廉价的商品

流体分析没有啊，力学分析呢，没有这些如何确定零件壁厚，如果选电机，等等，这才是核心的东西，所以没公开，没有这个核心的东西，就没有研发

同意楼上，核心哪有那么容易知道
