几分钟就助你从语言能力上成为3D建模设计达人!(IV)–建模语言背后实际是助力数学智能的综合提升

Chinese

到目前为止,你可能在模型软件里到处都能见到不同的形状或模块!对于这个现象,实际上也有一个词叫“俄罗斯方块效果”(Tetris Effect)。

但是,认真地说,把3D模型设计引入到学生中,为数学教学开辟了一条新的方式方法。此方法倾向于强调深入概念的实际理解和运用,并有能力让学生在学习数学时需要额外的语境和陈述。它也为学生们提供了像真正的数学家和设计师一样说话的训练平台。让我们一起来看看是如何进行的:

将几何学习带到更深的理解和运用层次

从教最初图形的名字到创建形状背后的数学逻辑关联,这里面有很多东西需要去探索。

一些相关3D建模软件上的词语:如联合、横切交叉、差异(或减)都可以在Tinkercad里用基本布尔(Boolean)操作直观地展示出来。

通过虚拟三维空间向学生发送任务

基本的三维概念与笛卡尔空间(Cartesian space)的教学吻合得很好。

一些相关3D建模软件上的词语:原点、坐标、积极地和消极地在作图面上教学生们如何进行各项功能键的导航和使用。再进一步操作就可以直接连接成动画了!

助我们的数学教学课程突破想象的界限,延伸到无穷远!

试想一下,像一位数学家似的挑战自己去解开一个数学秘密使学习的更愉快和有激励性?那就要从现在用3D建模软件教你的学生如何聪明地用一些诸如“智能复制”功能键,即选择了一个对象后,按下Ctrl + D,接着移动,旋转或缩放此模型后,再多次按下Ctrl + D,从而在原点和复制点中间创造出新的复制模型出来。

一些相关3D建模软件上的词语:如相似性(Similarity)、一致性(Congruence)、图案(Patterns)、镶嵌(Tessellation)、并行(Parallel)等。

3D建模作为媒介在数学和艺术的交汇中进行创新的学习。

在Tinkercad的3D建模中有一些具有特色形状被用来创建模型的曲线等,而这些都是由一名法国工程师Pierre Bézier贡献出来并命名的。他使用这些图像和曲线等技术在70年代时设计了雷诺汽车的主体结构除此之外,还有很多方法可以用3D建模软件同时对数学、艺术及语言进行融合学习。

相关的3D建模词语有:贝塞尔曲线(Bezier Curve)、样条曲线(Spline)、分形图(Fractals)和维诺图(Voronoi Diagram.)。

希望以上3D建模功能键的进一步介绍内容对感兴趣学习此类技能的学员们给予些许帮助。若你仍对某些功能键不明白或想进一步掌握的话,可以通过圆创屋的入门套件视频 学习进行直观的了解和练习。除此之外,我们还提供了除Tinkercad外的剩余四中免费易学且实用的建模软件(Fusion360、Blender、SketchUp和123D Design)的视频学习套件,欢迎订阅预览。

更多的3D建模设计的实用知识,我会继续在以后的博文中与大家分享。谢谢您的关注和阅读!

几分钟就助你从语言能力上成为3D建模设计达人!(III)– 像专家一样展示你的高级能力水平

Chinese

通过我之前与大家分享的两篇关于3D建模工具术语知识介绍后,想必有些朋友们已经迫不及待地想进行下一步的学习了?那就让我们继续努力前行吧。

提升设计技能的下一步是学习Fusion 360这款3D建模软件。在你开始之前,你应该注册一个Fusion360账户(免费给教育工作者和学生的哦)。

在探索Fusion360之前,你会发现这款软件里的工具与我们之前介绍的Tinkercad有许多类似之处。这是因为这两种产品都是以彼此一致的方式建立起来的,并为所有用户都建立一个清晰的、可访问的路径,使之更高级和具有实用性。

让我们通过对以下的术语学习来对3D建模技能开展更进一步的了解与掌握吧:

主体(Body):建模工具。您可以使用单独的机构来添加或删除几何体来实现设计的最终形状。例如,你可以为杯子和杯子的另一个主体制作一个咖啡杯,然后将它们连在一起。在Tinkercad里主体可以比较形状- 例如:形状可以组合成部件,主体可以组合成组件(Group)。Fusion 360支持三种类型的物体:固体/表面物体、雕刻体和网状体。

联合(Combine):把两个物体或部件组合成一个部件。可以同Tinkercad里的编组键(Group)进行对比。

组件(Components):用在其他建模实体的“容器”。它可以包含草图、结构几何体、甚至其他组件。组件代表真实世界的部分;制造出来的东西,可以互相装配。如果你已经有了一个你正在做的计划,最好用一个组件开始你的设计,然后在其中构建它的主体。

横截面(Cross section):把一个物体顺着一个轴进行垂直切割。在Fusion 360中,你可以用此工具来分析你的设计模型。

连接(Joint):用于装配组件和创建部件之间的机械关系,包括定义运动。了解更多关于不同类型关节的信息。

阁楼(Loft):在指定的距离上从一个形状过渡到不同的形状。例如:从一个长方形过渡到一个圆形或像船体一样的形状。

网格(Mesh):是一个顶点、边和面的集合,可以描述三维物体的形状。顶点是一个点。边是连接两个顶点的直线段。面是由边围成的平面。当用Fusion 360创造固体/表面物体时,它同时也支持网状体的建模。

参数建模(Parametric modeling):能助你描述想要数值的一种工具,并允许设计者通过改变其约束或参数来改变模型中相对应的属性,从而改变整个对象的位置或布局。例如,当你设定好一个能描述管口盖大小的参数后,随即创建完一个管子模型后,不管你所划出的管子有多长,通过此工具都会自动将管口盖放在管子的端口处。

路径(Path):在Fusion 360中绘制模型时出现的一条线。一条路径由一系列的点组成,这些点叫做“锚点”和这些点之间的线段。路径两端的锚点具有“控制句柄”,它们可以用来控制曲线路径的方向。

轮廓(Profile):一个二维草图,可以挤压成三维立体模型。

渲染(Render):创建一个模型的最终图像,它显示了应用于对象的所有表面属性。这一过程包括添加所有颜色、阴影和其他元素,如材料的物理外观,从而增加了真实感。

旋转(Revolve):绕着一个轴扫描一个二维物体后所生成的一个三维立体的形状。

塑造(Sculpt):使用直接操作创建有机模型的建模方法。你可以从五种基本的形状上进行操作:方格、四方球体、圆柱体、圆环和球。在塑造空间区域里,你可以通过简单地在细分表面上进行自由地按压或拉伸来探索这些形状的塑造。

剥落(Shell):从零件内部取出材料。即在一定厚度的墙体里挖出一个空心/空腔区域来。

模拟(Simulate):通过计算机模拟所创模型在现实世界中的作用来检查和测试此设计的实用性。这些快速迭代或测试的目的是提供有用的视觉反馈,在实际被制造出来前,以便更好地理解和改进这些设计模型。

切片(Slice):将固态物体分成两个或多个单独的三维立体模型。

扫掠(Sweep): 沿一条曲线把轮廓草图延伸到三维立体模型里。它需要两个草图,一个用于配置轮廓,一个用于路径。

希望以上3D建模功能键的进一步介绍内容对感兴趣学习此类技能的学员们给予些许帮助。若你仍对某些功能键不明白或想进一步掌握的话,可以通过圆创屋的入门套件视频(http://3droundhouse.com/how-to-videos/starter-kit/?lang=zh-hanshttp://)学习进行直观的了解和练习。除此之外,我们还提供了除Tinkercad外的剩余四中免费易学且实用的建模软件(Fusion360、Blender、SketchUp和123D Design)的视频学习套件,欢迎订阅预览。

How to protect your and your child’s product design ideas

English

OK! After reading my recent posts where I laid out the idea that you and your family can use your children’s creativity to prototype product designs, you now need to know how you can protect your ideas so that you can potentially gain royalties for your children’s college funds. Here are five key ways.

Doing some homework

  1. Pick the right manufacturing company. My last post discussed industries that practice the concept of Open Innovation, where firms are willing to share profits with you provided you can help them design a better product. Are there companies that will try to steal from you? Of course! But that doesn’t mean you can’t find reputable ones either. Tap into a social media network, such as LinkedIn, that can shed light on how the company does business. At the least, find out if they’ve been sued. As there are thousands, if not tens of thousands, of companies for each industry, there is no reason to tie yourself to any one of them unless you can trust them. Remember, it should be a win-win scenario for both sides.
  2. Understand how manufacturing works. The more you know how manufacturers in a particular industry produce and make money, the easier it will be to talk with them. Although you are not officially part of their R&D team, thinking and speaking as they do, especially in their own jargon, will give you a great advantage over other product designers who didn’t take the trouble to learn this. Remember that all manufacturers need to know how much your idea is going to cost them. If your idea doesn’t improve their bottom line, they have less of a reason to sign you up no matter how good your relationship is. Knowledge really is power and here, and knowing how manufacturing works will allow you to understand how your idea fits into the company’s overall strategy, thereby offering you a solid ground to stand on and hence a real form of protection.

  1. Create a paper trail. From the day you and your child come up with your product idea, take written notes on all improvements or modifications, all meetings with all relevant parties, and store them in a safe place. If a dispute or even a misunderstanding arrives, especially related to idea ownership, your written notes can provide an additional layer of protection. Consider it your “creativity diary” which you can write with your children, which I’m sure they will enjoy creating.
  2. Share your idea on a need-to-know basis. Until you apply for a provisional patent (see below), your idea is up for grabs. However, unless your idea is absolutely ground breaking in every field imaginable, I think most people are unlikely to take your specific idea to market given how this is not a sprint but a marathon. Nonetheless, you can protect yourself by just sharing your idea with those who can help you take it to the next stage.

  1. Apply for a Provisional Patent. This is a big topic that can fill a book because it also extends to full patents, not just a provisional one. For now, just be aware that anyone can file a Provisional Patent on-line in the United States Patent and Trademark Office (USPTO) for a very cost effective USD65 to protect yourself for 12 months. This means if your product is made and sold, it can have “Patent Pending” stamped on it. This also means you could be getting a royalty fee for you and your child’s design work. I’ll discuss more on this topic in the future but you can start with this USPTO link targeted to families!

 

The Not Yet So Obvious Benefits of 3D Modeling for 3D Printing

English

3D printing technology makes progress every day. It reaches more and more areas in our lives. In the years to come, it will be a common thing to get something through a 3D printing service. Today I would like to spark a new idea in your mind and the mind of your children.

3D printing just a few years from now

Imagine for a minute your kids have grown up a little bit. You are about to build a new house in the countryside, on the seaside or in the mountain (or anywhere else you would like to have your new house). You are having a meeting with your architect to decide how to design your house. He tells you all the requirements for energy efficiency, comfort and safety. Suddenly, he looks at your child and asks him:

“Do you know how to create 3D model for 3D printing?”

You are surprised. The architect goes on:

“As you probably know, building technology has improved greatly these last years. I was wondering if your child could design his own living area, so we can 3D print his model for him. You too could model some parts of your house to make it unique.”

Two scenarios

Now, dear parents, you have two possible situations:

Situation 1: Your child and/or yourself have never created anything in 3D. Needless to say, something specifically for 3D printing.

Situation 2: Your child and you have already practiced several times 3D modelling for 3D printing. You had lots of fun and have already several Family Made 3D printed objects at home.

In which situation would you like to be? 1 or 2? I would personally prefer the second situation.

Maybe you are telling yourself:

“Patrick is a nice guy, but it will be long before we can do this kind of thing, like modeling all or parts of our living area.”

Really? Think about it. Building constraints have considerably changed. New concrete allows funny shapes as strong and durable as reinforced concrete without iron rods. 3D printing technologies specifically for the building industry are popping all around the world. They progress quickly. Sooner than you think, you will be able to 3D print the house of your dream.

My advice for today

Begin as soon as possible to think about your new house in the shape of a concert grand piano or the shape of a delicious mango.

What is Open Innovation and how does it work?

English

If our children can prototype a product idea or innovation to manufacturing companies, how would these corporate Open Innovation programs work? As I mentioned in my earlier blogs, we can work with our children to license an idea to a company who would pay us a royalty to help with the children’s college fund. But critical to this process is to understand what Open Innovation is and how it works.

Defining Open Innovation

First, you should know that the person who popularized the term was Dr. Henry Chesbrough, who currently teaches at the Haas Business School, UC Berkeley, in his 2003 book, “Open Innovation: The New Imperative for Creating and Profiting from Technology.” In a more recent Forbes magazine article, he provided a (rather academic) definition: Open innovation is “the use of purposive inflows and outflows of knowledge to accelerate internal innovation, and expand the markets for external use of innovation, respectively.”

The catalyst

 

Personally, I prefer Wikipedia’s explanation: The central idea behind open innovation is that, in a world of widely distributed knowledge, companies cannot afford to rely entirely on their own research, but should instead buy or license processes or inventions (i.e. patents) from other companies.

 

Pluses and minuses

Of course, there are advantages as well as disadvantages for companies that engage in Open Innovation. Here is a partial list, also from the Wiki article:

Advantages

  • Reduced cost of conducting research and development
  • Potential for improvement in development productivity
  • Incorporation of customers early in the development process

Disadvantages

  • Possibility of revealing information not intended for sharing
  • Potential for the hosting organization to lose their competitive advantage as a consequence of revealing intellectual property
  • Increased complexity of controlling innovation and regulating how contributors affect a project

 

A key corporate trend

 

How it works

So how does Open Innovation work? While there are different methods, such as those sponsored by governments or competition based, the one we are most interested in is the “Collaborative product design and development” model. Here, a company still controls and maintains the production of the final product, but it is sharing the sales revenue with external co-designers (that’s you!) because you have found a way to make the product more usable and thereby more acceptable in the market. By using an outside co-designer, but maintaining production control, companies can get their new products to the market faster than just relying on their internal R&D departments. You will need to find ways to protect your own ideas, which I will discuss in the next blog.

 

Who’s practicing Open Innovation?

We want to look for inventor friendly companies or companies that are in industries that are constantly looking for new ideas to stay ahead. Here is a list of “15 Examples of Open Innovation between Big Companies & Startups.” And here is a very long list of “Inventor Friendly Companies.”

Looking at these two lists, which include even massive companies like GE, it should be very clear that Open Innovation is a key trend for many industries. This is because corporations understand that that we are living in information and technological boom times and they need to be part of that or risk falling behind.

For us parents with kids, with the cost of prototyping MUCH lower than just 5-10 years go, thanks to 3D printing technology, I think our children’s creativity need not be restricted to homework assignments, when they can be applied in the real world! The children provide the creative spark and we provide the discipline to make a very natural alliance that will hopefully and eventually help the children in their future education pursuits. What do you think?!

Key steps to working with your children to prototype products, earn money for college!

English

Following my earlier blog, where I listed “Five ways to find quality time with your children” where the central focus was time management, we now turn to prototyping products, yes to help your children build their college fund! If you think this idea is far fetched, please have a look at my reasoning in my other blog here. My main point is we can create a triple win scenario where 1) children can apply their creativity in the real world through new product design or improvement, thereby attracting the attention of any college, 2) companies can tap into a new source of creativity, and 3) parents have an alternative funding source for their children’s college fund.

Here are the key steps:

  1. Read One Simple Idea. Stephen Key’s book is based on his 35-year’s experience as a product designer who struck over 20 licensing deals with manufacturers in different industries to earn substantial amounts in royalties. He also has a YouTube channel where he  explains his 10-step plan in further detail. While the process does take time, I think it’s quite achievable for anyone who puts his or her mind to it. Even Key admits, he has neither engineering nor any specialized background to improving products. But he does have a passion for creating new things to make everyone’s lives just a little better. Big helpful hint: you don’t need a full patent to get a licensing deal; just a preliminary patent via the US Patent Office will suffice. (Please note, I currently have no connection with Stephen Key beyond reading his book and watching his YouTube channel.)

  1. Find an industry that interests you and your children that practices Open Innovation. As product cycles become shorter and shorter, companies just don’t have the resources to creating new products on a regular basis. Some industries, like kitchen appliances and pet products, are willing to share their profits with outside designers. These Open Innovation companies even have a link on their website that explains where outside designers can submit their ideas.
  2. Learn about the buyers and sellers in the market. Once you find the industry that interests you and your children, try to learn about it as much as possible. This is one of Key’s most important steps. It’s the only way to speak to the manufacturers at their level and keep you in the licensing game.

Start of a licensing deal?

  1. Prototype with 3D printing. Key says in his book that even a 2D drawing is enough to result in a licensing deal. But he nevertheless supports using 3D printing in his YouTube channel. I think creating your own 3D printed prototype is a good way to establish and protect yourself, as it will add to your documentation that the idea is your own.
  2. Have fun! Key says licensing is a numbers game; you might not get a deal until you’ve submitted many designs to many companies. But I think this is part of the fun! How many famous inventors, entrepreneurs and leaders have not seen failure in their life before they began to succeed? We all want to know what DOESN’T work as early as possible because it will help us get to the things that DO work sooner. This in itself is a great life lesson for our children.

More to come on this topic!
