We brought the engineering design solutions "Particularly to answer these below comments".

http://www.coroflot.com/public/individual_file.asp?individual_id=139118&portfolio_id=2198669&amp

1."It can’t work! You can’t use it when the wire is wound because of the joule effect loss and overheating… This electrical device will be rejected by most of international certification! Not safety at all"
2.In that case, why does my vacuum cleaner not over heat when the cord is not completly unwound?

3.Electrician says: Most wound Cable systems have a reduced max Amps while wound up. for example in Sweden we have coils for outdoor use that when coiled up they are max 230v 10 Amps and when stretched they are max 230v 16 Amps to compensate for extra heating when coiled

4.Yeah, this would definitely still work and not overheat. Shielded wires have negligible effects on each other even when they are wound.

5. This would be great if it could exist, but I agree with sponge bob’s comment above, it would be rejected as dangerous.

(Coils of extension cords must always be uncoiled before use, they can get hot very quickly. Otherwise, it can melt the plastic around the wire and fuse the whole coil together, and create a nice short circuit, or fire)

6.Just shield it correctly and you’ll be fine. We have shit on space shuttles that withstand entering the atmosphere. I’m sure in this day and age we can insulate a coiled cord.

7.OK, enough with this nonsense. There’s no problem with the coil, the only problem is that you have to make a hole in the wall for the coil, and some walls are too solid or too thin so it will be tricky.

8.I had one of those rollable extension cords. They’re worthless since they tangle themselves after a short time.

There’s already wireless electricity in the market so I don’t see any sense in this. I say make wireless outlets and make every appliance we have utilize the wireless electricity tech.

9.the coil shouldn't be a huge problem, its a simple heat transfer problem, at the very least it can be easily found out if it works or not. for safety, it can be used for less Watts while wound up, and more Watts while stretched. A simple calculation can determine the maximum power allowable in each way.

10.amazing idea, i don’t understand why none of these come in North American socket patterns, even the cool 5 inlet one you posted a month ago was euro plu

11.Lol…i find this idea stupid. Not only u have to dig out the wall, but maintenance will be so difficult. Whats wrong seriously with buying a multiple extension cord ?Think as a buyer and u see how irritating it will get in the long run.

12.Best idea ever

13.This looks great. When do you think it’ll hit the markets? If that’s just a normal extension cord in the wall then you should be able to have one that’s longer then 1.5m right?

14.

This design is possible, this system is possible.

That being said it would cost a considerable amount between install and hardware (the cost will also reflect the R&D involved and the cost of it getting certified).

God forbid there’s a problem down the road.

So basically you install this gimmicky

design in hopes of becoming more lazy an to avoid going into a closet to get an extension cord.

How often do you need an extension cord in your house anyways? do you plug you hairdryer in the bathroom and blow dry it in the garage?

Who needs this? What do you plug in and need to walk around the house with?

this is pointless.

word up

15.http://www.coroflot.com/public/individual_file.asp?individual_id=139118&portfolio_id=2198669&

16.Dr.Safety says

Not going to go into production….Its a huge fire hazard since the wire is coiled up on itself which will produce a decent amount of heat if the outlet is under a heavy load such as a hair dryer.. The design is Nice but the safety side needs a little more attention

Innovations: Surfboard Removable Fin System base attachments.

2009-09-23T02:10:00.000-07:00

Removable Surfboard Fins

Removable surfboard fins were around as early as 1954, however they weren’t interchangeable and there weren’t scores of different designs available at the local shop.

Tom Morey was a key figure in introducing removable fin systems with several types of fins in the 1960’s.

In the early 1990’s a number of new removable fin systems sprang up in conjunction with the burgeoning popularity of the thruster design. FCS, Future, Red X, O’Fish’l and Lok Box were among the early industry leaders.
Advantages
Removable fins surged in popularity due to the ease of use—especially for shapers and surf shops. The danger of snapping off a glass-on and ruining the board was no longer an issue. Manufacturers and retailers were able to ship and store more boards with less risk.

FCS also built its marketing strategy around the fact that removable fins made surf travel much easier. Having professional sponsors like Kelly Slater didn’t hurt either. Slater’s blue and white signature fin has become an icon for FCS and the innovations it was ushering in.

The ability to manufacture precise molded shapes with computers has also pushed removable fins to the next level. Glass-on fins must be shaped by hand during the sanding process, and no two are ever the same. FCS even tests their new designs in Tasmania, where one of the world’s two hydrodynamic chambers is located.

Advances have also been made in the realm of the material the fins are made out of. Lighter fins are now possible, and several fin companies have introduced some exotic materials such as fiberglass resin, carbon composite, and ultra light epoxy.

Disadvantages

Unfortunately, there is no universal fin system. You must find fins that work with the base connection built into your board. If you want a particular style of fin that is made by FCS, but you have Future connections on your board, you’re out of luck.

One of the basic problems with removable surfboard fins is the fact that they can be vulnerable to falling out and snapping off at the base. FCS fins are particularly guilty, as the way they connect to the plugs is rather weak in comparison to a system like Future. Some would argue, however, that it’s better to snap a $15 fin than break a glass fin.

Most removable fin systems, with the exception of companies like O’Fish’l, use metal screws to hold the fins in place. Unfortunately, this metal can strip, rust, or corrode, and replacement is difficult. You can prolong the life of your screws by rinsing them with fresh water after your session.

Despite a few drawbacks, it’s probably safe to say that more advances have been made in surfboard fins over the last 15 years than in board design itself.

Robust Engineering design services, have designed a new quickly removable fins with solid base attachement.

There fore using metal screws to hold the fins in place is not needed. Unfortunately, this metal can strip, rust, or corrode, and replacement is difficult.

You have to prolong the life of your screws by rinsing them with fresh water after your session.

Making a New Plastic Product

2009-08-03T20:44:00.011-07:00

End of this Session, I will take you to the level where you will have 100% knowleadge to design your own plastic product.

How does a designer begin to make the new or redesigned product?

First of all, the designer must decide which type of plastic to use for his product?

Secondly he must select the best method for [processing the plastic to create the finished product.

Step 1:

Choosing the proper plastic.

There are so many plastics, each with specific chemicals and physical properties which will effect the performance of the product. There can be vast differences in processing these plastics.

There are two basic types of plastics Thermosets and thermoplastics.
Engineering Plastic materials

Selecting the Best Processing Method.

Thermoforming
Rotational molding
Structural form molding
Extruding
Extrusion blowing( Blow molding)
Injection Blow molding
Stretch blowing
Compression molding
Transfer molding
Injection moulding
Injection-Compression molding
Reaction- Injection moulding
Expandable bead molding
Lost-core molding

Not all plastics are suitable for this process.

Advantages and Disadvantages of the above methods.

Processing under this category includes compression, transfer or Injection molding of thermosets or thermoplastics

Advantages: Suitable for any size product from those weighing fractions of a gram to large
pallets and containers weighing 40kg and more.
Excellent surface definition
Good accuracy
Good repetitiveness
High Productivity
Product finishing usually is not required after molding

Disadvantage:

High Mold and machine cost

We are only going to focus Injection and Blow moulding process in this blog, however we should consider some of the other Plastic processing methods which is available to use.

Extruding:

"Robust" Cloth Peg design

2009-05-28T04:02:00.000-07:00

Robust engineering designed its revolutionary Plastic cloth peg.

General cloth peg design Overview:

Clothe pegs are essentially compliant fasteners. They must be sufficiently flexible to accommodate a range of cloth thickness without generating too great a variation in clamping force.

The old style and new styles are achieve this by means of flexible legs which are in effect beam springs.

Helical coils also be employed as torsion springs. The central axis of the helical coil is always the torsional axis of the spring. We expect that most of readers will familiar with this plastic device.

No manufacturer has ever done so far this design by engineering analysis. Skilled model maker would have caved a few dozen pegs and sorted out a good shape by trial error. But Robust engineering suspect that, it is because the manufacturers had no enthusiastic engineer handy.

An insightful engineer, with a modern of engineering structural mechanics theory, Simple single plastic part design, revolutionary mould design,

can develop quite good revolutionary mathematical models to predict its spring stiffness and other spring characteristics from first engineering principle.

Robust engineering designed its cloth peg which has the following advantages.

Corrosion free therefore no cloth marks.

-Solid plastic part design without having any steel springs

Saving our environment .

-No disposable Plastic parts this means product designed to minimized its functional failure

Can be use out door as well as indoor applications.

-Easy conversion to use this product as a wall rope cloth hanger.

Easy to handle.

-No "pop out" or "break out" during serious wind conditions

Revolutionary Mould design which will ease the product manufacturing and difficulties in Injection molding.

Therefore very competitive Single plastic product, which would have great potentials to lead a role among its cloth peg design competitors!

Engineering Design Analysis

2009-05-12T14:17:00.000-07:00

FEA analysis in

Pro Engineer /Mechanica

We make consistent reference throughout this blog to engineering judgement and wisdom. Some of this wisdom is acquired through years of practice in the design profession, but much of it is gained through close association with my inspired and creative business directors.

Engineering design is an engineering discipline.

Design Against Failure

Engineers/Designers use materials, whose properties they do not properly understand, to form them into shapes, whose geometries they cannot properly analyse, to resist forces they cannot properly assess, in such a way that the public at large has no reason to suspect the extent of their ignorance. John Ure Engineer 1998.

Stress Analysis

One of the real problems we shall face in this area is that of relating the strength of an element to the external loads which are imposed upon it. These external loads cause internal stresses in the element. In this analysis we shall concern ourselves with the determination of these stresses.

We will introduce the concept of strength and begin the process of relating strength and stress to achieve safety.It is worth observing that the stresses which are calculated are only as reliable as are the external loads and geometries which are used in the determination. Once a product has been manufactured and placed in the hands of the consumer, the manufacturer has no control over that product and , to some extent, over external loads to which it may be subjected.

It is for this reason, among others, that testing and experimental proving are so important in the design and development of any Product development.
