#12 Block grabber with functional lock by ms12shah
Herein i have integrated the functional mechanical ratchet lock assembly in to the grabber, and for now i have uploaded the 3d model and assembly drawing as well. 3d model and the assembly drawing will make it easier to understand the mechanism of lock and unlock.
Animating the entire mechanism parametrically will consume lot of time, thats why i have not submitted it for now. But if i am declared a winner i will definately animate the mechanism , for its core functionality.
thanks

#5 Mechanical grab with ratchet by Saurav
This model is designed,considering all steel members.The model is ready to be manufactured with shop drawings.
Model is structurally stable through CAE analysis.
I can share the documents once the idea is selected.
As the buyer asked for a simple ratchet mechanism,that has been designed too.Pls have a look on attached images.
Regards
Saurav

come on my design from the first was with the most look alike whitht the hook the mechanism. the only thing i cant nott figure out was how was assembled part of the ratchet mechanism. but with all that feedback im shure that @ms12shah will do the work. with that last picture http://www.brianscottengineering.co.uk/images/Attachment/Block%20Grabs/block-grab-main-04.jpg
it will be very easy to understand and model it.


anyway congrats to the winner!

m12shah, please understand that i do not need photocopy of the design that was shown in the link's picture. I need a rachet lock that should work mechanically because i need to fabricate this physically and if it doesnt work then it is a failure for me and my time will be wasted. Kindly submit an animation of the working racket lock with a gear incorporated

Thanks dreamcast,
But why the lock is not acceptable,this type of lock is a simpler form of ratchet is widely available in market.I just fabricated it with simplycity.
However never mind.
Thanks again.

Actually sir time was too less to understand the mechanism and integrate it into the model, that,s why i did not do it. if you need i can integrate it into design now.

Thankyou everyone,
I have reviewed the enteries and the most nearest possible design is by m12shah but there is no lock details or renders, i kindly request that.
Good Job by fercas, still no lock detail
Good attempt by saurav although this type of lock is not acceptable.

Hello, im startying with cadcrowd but i have A LOT experiene in mechanical and machine Design for this kind of aplicattion. i can do the work, and include all the FABRICATION DRAWING with all the specifications needed, unfortunatly due to my currently workload i can not will start it until 16 sept 2016 (today 14 sept 2016). the work will be done in 1 day of work. but i will not do the Fabrication Drawing until have presented the 3D concept and had your approval so this waywe do not inves too much time in previous drawings. if you agree in all of this ill start with te concept as soon i can on 16 sep 2013

Cat Earred Headphones
We want a set of headphones designed that have cute cat ears designed on the top of the headphones. The mockup that we will include uses Beats Solo HD headphones as the template. This an easy way for us to portray the aim of the project, as we want the final outcome to look sleek and simple, but not exactly like Beats. We want a redesigned set of headphones that has fashionable cat ears on top suitable for young 20 year old females. Make 2D mock ups to give us an idea of what you have designed, then also to make up plans that can be sent to manufactures for immediate production, preferably in a cad format that can be used to 3D print the shell. Color, style, aesthetics are all up to designer, but general preferred color themes will be for white to pair with pink, and baby blue to pair with very light red.
MuTT MoTE™ and MeOw MoTe™

Brick of Money
The goal of this project is to design a desk ornament that is a conversation piece. https://goo.gl/wc3ueb There are 3 aspects to this product: 1: The foundation: A rectangle of solid metal. Should have an expensive high end look. A bar of silver is the only thing I can think of as an example foundation. https://goo.gl/wMySnL However, I am going for more of a brushed nickel look. 2: The casing that sits on top of the medal foundation. This casing is either made of glass or plastic and will be glued to the medal foundation. 3. $500 in one dollar bills will be inside the glass casing. The attached image is not high end looking but should give you a basic idea of the kind of product we are looking to develop.

Ergonomic Laptop Stand
Many working professionals are using laptops on a day-to-day basis. Laptops however, are not ergonomically designed to promote good posture and typically it results in back and shoulder problems for those that use it. Health professionals recommend that the screen of a laptop be at "high-five" level - being at eye level that your shoulders are relaxed backwards and you are not hunching over the screen. This is the best posture for you to be in while working on a laptop. Currently, there are no innovative new ideas for creating a highly mobile and cost-effective product which can solve this problem. I am looking for a design which can encompass designs from nature to raise a normal laptop to a point where a user can work on it while holding the best posture.
