机械设计的基本原理1.5
Deterministic Design: Play
确定性设计：”玩耍”
An engineer or a team with focus can follow a natural progression of events and they will likely be successful. A large part of the process will require the engineers to fully immerse themselves in the development of the solution. In the case of a mechanical problem to be solved, this often means a lot of physical play. In the case of a software problem to be solved, virtual play rules! In all cases, just as we learned as children by playing, playing continues to be a very important part of the adult learning process.
一个专注严谨的工程师或者团队，往往能够自顶向下，成功地完成设计任务。大部分设计过程中，工程师都必须全力以赴，寻找解决方案。涉及到机械设计中的一些问题时，就需要工程师实施一些测试。涉及到软件工程上的一些问题时，需要工程师实现虚拟的调试和调用。无论什么领域，我们都可以像小孩子一样，持续通过“玩耍“来学习和进步。
• Playing with problems and available resources enabled humans’ brains to evolve. Play involves all the senses, and as they send signals to our brains, our bio neural nets are activated, and the ideas begin to flow:
熟悉问题本身以及可以调用的资源，可以促进我们的大脑进步。通过“玩耍“的过程，我们的大脑神经中枢会受到激发，从而促进我们思考：
• Look at the problem and resources available to you:
熟悉问题本身以及可以调用的资源。
• Create mental 3D images and movies of the problem and manipulate them in your mind so your bio neural net can work on solutions while you do the laundry.
在脑海中假想需要解决问题的3D图形，即使洗衣服时，你也可以想想可能的解决方案。
• Touch the parts of problem and resources available to you:
把玩涉及问题的零件和资源：
• The weight and size and feel of the physical elements enters your neural net through your fingers and you become one with the hardware so you can better imagine the actual physical response of the system.
实物的重力和尺寸会给大脑提供理性的认识，这样就可以更直观地想象零件在实际应用时的变化。
• Listen to the sounds that are associated with the problem and the resources:
倾听与问题相关的所有声音。
• Patterns in sound often give rise to identifying the true performance of a system.
声音的模式会提示该系统的实际性能。
• Smell the problem and resources to build a better actual bio neural virtual net model of the challenge.
调动五官，尽可能的建立一个脑海中完美的图像，以助于解决问题。
• Taste victory (or the resources if this is a food-based challenge) by imagining your solution is the one that wins!
脑海中假想你的方案已经成功，尽情品尝胜利的喜悦。
• Sketching the problem and possible solution strategies and concepts is how we communicate with others, including ourselves:
描绘出问题以及其可能的解决方案和概念，这样我们才可以与他人和自己进行沟通：
• Sketch the problem so you can look at it from different perspectives.
多角度出发描绘问题。
• Sketch possible solution strategies and concepts so you can tape them to the wall and scan them all simultaneously and search for strengths and weaknesses.
描绘出所有可能的问题和解决方案，把它们钉在墙上，同时审视并思考每个解决方案的优劣。
• Modeling the problem and possible solution strategies and concepts allows you to better play and develop and evolve solutions:
通过建模分析问题和解决方案，通过获得更多细节来提升解决方案的可行性。
• Simple physical models allow you to better play with the system and they often help to identify the system’s most sensitive parameters.
物理模型能够更好的反应问题本身，更有助于找到系统最敏感的变量。
• Analytical models can allow you to identify the most sensitive parameters of the problem and help guide your solution path:
分析模型，同样也可以帮助我们找到最敏感的变量，从而引导我们找到答案：
• Analytical models can identify equine orientation BEFORE you hitch your wagon to them (and then try to beat them to move).
分析模型可以帮助你在对的方向投入对的精力，而不是南辕北辙。
• Analytical models can enable you to optimize your solution to minimize cost and effort.
分析模型可以帮助你优化解决方案，实现低成本，高性能。
• Analytical models allow others to understand your intent.
分析模型可以更好地帮助他人理解你的意图。
• Detailing the solution before you build can help identify minute yet critical features that may otherwise cause failure:
在实际制造前就考虑解决方案的细节，有助于发现关键特征，从而减少失败的概率：
• Bolt holes should be drawn so you can envision how the system will be assembled.
确定螺栓孔的位置可以帮助我们确定系统的装配方式。
• Every little chamfer need not be put in if you are creating a bench level prototype.
如果是做快速原型测试，那么细节处的倒角不需要考虑。
• Building and testing your solution is the physical realization of all that you have worked so hard to achieve:
最终通过装配和测试来验证自己的解决方案，是所有努力的结果：
• Like ourselves, most things have to evolve, so finish early and be your own toughest customer!
所有设计和产品，都会随着时间演化。所以早点完成设计，想想更好的实现办法。
• If you were continually assessing risk and planning countermeasures, if tests reveal a problem, you will be more likely to recover.
如果在设计起初就考虑到风险和对策，那么测试即使时发现问题，你也更有可能弥补这个错误。
Following pages will systematically describe a design process that can be a useful catalyst to help you develop your ideas.
接下来的几章，会系统性的给出一个设计流程，从而帮助新手们实现自己的想法。
Play with the contest table and the kit parts. Sketch the different operating conditions of the table and animate them in your mind to see what might be most easily exploited. Make a solid model of the table and collect solid models of the kit parts. Use the solid model of the table to acquire mass and inertia properties and combine these with the power of the motors to get an idea of what might be achievable in the allotted contest time. Create some simple physical models that allow you to better play with the table and to help you better identify scoring opportunities and develop elegant strategies. Think ahead about how much detail will be required to realize your strategies, and determine if you have the resources to actually build and then test your solution. Update your web page (as you should do every time you have a significant advance. No more reminders will be given; you all are big geeks now).
努力熟悉竞赛场地和工具箱里的零件，试着在脑海里想象不同的得分方式。像播放幻灯片那样，确定那种方式是最容易的。通过建立模型，确定质量和惯量等参数，从而通过电机的功率来确定得分所需的时间和可行性。此外，还可以自己做一些物理模型，验证别的得分策略和发现新的机遇。之后，通过分析现有资源，确定自己是否能够实现特定的方式来得分。更新你的网页（只要你有重大的进步，就应该及时更新。无需老夫再多提醒，诸位已经具备极客级别的思想了）。
