    Computer aided design is the backbone of designing products and machinery. It used to design 3-D mechanical products. It was developed by Dassault Systèmes SolidWorks Corp., a subsidiary of Dassault Systems. SolidWorks is currently used by over 2 million engineers and designers at more than 165,000 companies worldwide.The average revenue for SolidWorks is about 483 million dollars. it was released in 1993 by Jon Hhirtchisk at M.I.T.and has sold over 1.5 million licenses world wide since. It is dubbed the most popular C.A.D. (computer aided designing)  software in the world. It is so popular that it has been installed onto every computer at Penn State and a requirement for all aspiring engineers to know.

    At first, i thought it was frankly a pain to operate this software but by the end of the semester i realized that it isn’t all that bad. It’s relatively easy to operate and the variety of features it has is great. My dad uses Auto-cad in his industry and he said that Solidworks was actually great and much better and began installing it everywhere in his engineering department! It’s got really cool features like the :

    • SolidWorks Simulation is a design validation tool that shows engineers how their designs will behave as physical objects.
    • SolidWorks Motion is a virtual prototyping tool that provides motion simulation capabilities to ensure designs function properly.
    • SolidWorks Flow Simulation is a tool that tests internal and external fluid-flow simulation and thermal analysis so designers can conduct tests on virtual prototypes.
    • SolidWorks Simulation Premium is a Finite Element Analysis (FEA) design validation tool that can handle some multiphysics simulations as well as nonlinear materials.
    • SolidWorks Sustainability is a product that measures the environmental impact of designs while they are modeled in SolidWorks

    I actually had the chance to use the motion feature for the class project in my Engineering Design class. Our project was to design a go-kart through the course of the semester with the help of 6 lessons, which we learned through the pre-installed tutorials. Pre Installed tutorials, they are literally lifesavers. Solidworks 2014 comes with 100’s of tutorials from the basics to the most advanced procedures on Solidworks so that everyone can learn them.

    The motion feature allows users to test their designs in motion. You can test the strength by ramming your go-kart into the wall; personally I think that’s pretty cool cause AutoCad does not have any of these animation features. We also got the opportunity to use Solidworks for the final Solidworks project. I redesigned my grandfather’s table back home, you can read up more about it on my portfolio site: sites.google.com/krish241195 . Another really great feature Solidworks has to offer is the vast variety of material selections. you can use anything for your products from Glass to Gold to Plastic to Wood! As far as my knowledge goes not many other major designing softwares allow users the opportunity of material selections

    Although the only issue I have with this software is that is Windows based. I would advise them to expand into the MacBook market sooner than rather than later as it is a great opportunity in this era of engineering design.

    Solidworks has recently just launched the newest updated version , simply called Solidworks 14

    Solidworks 2014 has the following specs;
    Faster system response and automated processes keep you focused on design
    Accurate visualizations
    Improved user interface and simplified process steps help you get work done faster
    Powerful new features and time-saving shortcuts increase design output

    The estimated cost for Solidworks 2014 is about $90.

    Below are a few more designs created using Solidworks (not by me though)

  2. One for all, and all for one!

    December 10, 2013 by Krish Shah

    coin

    As people get richer, they invest more in technology, leading to new inventions and innovative products. But the money they invest, where is that stored? Credit Cards? Debit Cards? Yes, and most owners of a debit/card usually have more than one in their wallets. I for one, have 2, one Indian and one American. Often people use the wrong card at times, and many other problems, like people might loose one of their cards and begin to worry. Usually the various cards in one’s wallet are from different accounts in different banks. So when I spoke to a few people in my EDSGN 100 class, especially the international students, they said that they’d prefer a ‘one card for all system.’ Well a company, namely Coin, has come up with an invention called the coin card.

    The Design:

    This is a payment card that stores different cards information on it. The thing that makes it different from other cards is the fact that it has a screen and a button on it as displayed below. Also, it stores details and information from various cards and various accounts. For example you can have a Bank of America account synced on it and at the same time have a Dena Bank (an Indian bank) account on it. Say you walk into a store, with the click of a button you can switch which account you want to use and then go ahead and swipe it. Voila! The card has a long lasting battery in it, which lasts for about 2 years per se. The battery bring up the issue of it being harmed by water, but good thing is that its water-resistant !

    The Coin Card is linked with Apple, so to add a card you have to use unique specific apple supplemental software. The card has pre installed Bluetooth 4.0 system in it, the ones smartphones have. And apart from that, the Coin application (only on apple) is said to be really helpful. Say you pay from your Coin and leave it at the cashier’s desk at Macy’s. When you reach a certain distance (about 40m) the Bluetooth feature communicates from the card to your phone alerting you about it. Oh and speaking about Macy’s, you can also store ALL reward cards on the Coin giving the consumers and added advantage and you might question about theft of the coin, if you loose one card you loose all? Valid question. But you can simply deactivate the coin card through your smartphone since the 2 are linked and incase you’re wondering ,yes it is ATM compatible!

    So here we can see that all the existing problems with the current payment cards, all vanish with the invention of the Coin Card. One of the best and most helpful inventions of the 2013 calendar year. It is set to go on sale early 2014 and would be for about $100.

  3. Run out of land? Make an Artificial Island!

    DIALOGUE BLOG

    The one city that is known for designing architectural marvels is definitely the city of Dubai. From the highest tower in the world to an artificial island, this city is definitely changing the world and the way we see it.  Artificial islands you ask? YES. The palm jumeirah is an artificial archipelago created using the technique of land reclamation.

    It was designed by a company called Nakheel and developed by HHCP architects after its development in 2005, the shoreline of Dubai increased by a total of approximately 320 miles and doubled the length of the Dubai coastline

    The design:

    It is a fine example of bio mimicry. Inspired from the shape of the Palm tree (hence the name). The island has 17 fronds that extend out into the sea and has an area of about 5x5km. Which is massive.

    An interesting fact is that is was made out of only sand and rocks and no concrete. Rumor has it that the Sheikh wanted to make the artificial island as natural as possible. Did you know? The Sheikh himself designed the design of these islands. “If god wanted an island in the shape of the palm, he would have put one, but he did not, so we will” are the words the designers of the palm jumeirah have said.

    It was made using 5.5 million m3 of rock and 94 million m3 of sand. One might wonder how it resists erosion in the middle of the gulf coast? Well the answer to that is that the sand, covered by an erosion-preventing water-permeable geo-textile, makes up the breakwater’s lowest layer. One-ton rocks cover the sand, and two layers of large rocks weighing up to six tons each cap the structure. A “toe” placed by a floating crane sits inside the Crescent. The breakwater also has two 328-foot openings on each side to eliminate stagnation in the 16 narrow, deep channels. These gaps allow water to completely circulate every 13 days.

    Sand being used in the construction as displayed below

    To get the complex shape just right, designers and contractors use Differential Global Positioning Systems to plot the palm and ensure the sand placement within 0.39 of an inch. More about this in mentioned in the video below. Since it is located mid-water, waves were posing to be a threat. To eliminate this issue, wave blockers were constructed all around the perimeter of the island. They are about 3m high. (Average wave= 2m). The base of these stoppers and the island as such were constantly monitored during construction process with the help of deep-sea divers. They check for the proper alignment and placement of the rocks beneath the surface to ensure its stability. However even though this is the most audacious engineering project to ever be built it has been coming a criticism lately. People have been talking about what would happen when sea levels rise due to global warming and there has been a projected storm in Dubai once every 100 years. Also earthquakes are projected to be on a Richter scale of 6, relatively high for a ‘sand and rock’ structure to withstand. Nevertheless, building an artificial island in the middle of no where with only sand and rock to attract tourist’s and set up a new place for hotels, residence and leisure, only a city like Dubai could have done that.
