A 3D exercise of a Billion router modelled by Neil Taylor

I am offering a new service of modelling simple 3D ideas for people searching People per Hour for good 3D modellers and design engineers.

You can see my profile at   https://www.peopleperhour.com/freelancer/neil/mechanical-design-engineer-industr/1477296

I look forward to helping clients visualise their ideas in wonderful 3D.

Of course I can offer much more detailed design work. This is just a taster of what I can do in 3D modelling with SolidWorks. See my website at Devon 3D CAD.

By the way, this is a very good router!

Mantle Clock, a Classic from 1930s

Mantle Clock, a Classic from 1930s

I have a small but wonderful collection of Mantle Clocks from the 1930s, including this classic design.

After a wave of wooden cases and then the new wonder material – Bakelite – manufacturers began to produce designs using the skills of the ‘Metal Bashing’ companies that were the backbone of light engineering in Great Britain. This example uses thin gauge steel pressings, steel die castings and a standard wind-up movement. I find the use of tiny fixing screws amazing. The tolerances are tight and everything fits together and runs like clockwork!

I have modelled this in 3D using SolidWorks. It was instructional just to take it apart – James May would love this product. Now, can I put it together again?

DC Power Socket 2.1 PCB Mount – another 3D solid model available for Engineering Designers to download for free from 3D Content Central.

This new model is in a series of popular Electrical and Electronic components posted on 3D Content Central. New models will be added regularly.

Please contact me at Devon 3D CAD to have your Products and Components modelled in 3D for uploading to this great site with a database of thousands of 3D Models.

Scissors 3D Model uploaded to 3D Content Central

3D Content Central is a website with a database of thousands of 3D Models on every subject under the sun, and I have uploaded my 3D Model of these scissors.

Design Engineers are often looking for a part to use in an assembly and don’t have the time to model it. They go straight to the 3D Content Central and search for a model of the part they want and download it for free. How good is that? Usually the models do not need full manufacturing details so long as they are dimensionally correct.

So if you, as a supplier, want to sell more of your products it makes sense to have them available on this website so designers can find them with little effort. Please contact me if you need your products modelled in 3D and I will be happy to help.

This pair of scissors is now uploaded to 3D Content Central for all to see.

SolidWorks Modelling in 3D, not the normal Mechanical Engineering models.

SolidWorks Modelling in 3D, not the normal Mechanical Engineering models.

If I were to spend all my time designing complex small scale electro-mechanical assemblies, I would be a very boring designer indeed. So I am starting a series of modelling familiar everyday objects using my trusty SolidWorks 3D modelling software.

The first model is of a pair of scissors. Not just any old pair of scissors but my favourite pair that I bought in San Francisco. I try to keep these for cutting non metallic materials and consequently they are in very good shape.

The major challenge was to faithfully represent the various sections, especially the shape of the handle between the finger holes and the blade. It is not circular and not planar – it also has a slight curve. I used a lofted feature which is OK but could do with a little improvement. It is extremely difficult to actually measure some of these shapes, so they end up as approximations. I modelled the finger holes as ellipses but I can see they are not quite ellipses in real life. Does it matter? Not  for the purposes of this exercise. I wonder what the German designer had in mind, for they come from Solingen.

Lasers in Medical Products – We can help in development of laser-based Medical Products

Lasers in Medical Products have a wide variety of uses. Neil Taylor at Devon 3D CAD played a major role in the design of the ‘PulseMaster’ Dental Laser for Incisive Technologies in California.

Lasers in Medical Products. 'Pulsemaster' Dental Laser designed for Incisive Technologies by Neil Taylor at Devon 3D CAD

Incisive Technologies near Redwood City in the San Francisco Bay Area selected Neil Taylor to provide Industrial Design for their new Dental Laser that was making its way out of the lab and into dentists’ surgeries.

As a Medical Product Designer I work with development teams enabling them to bring together their medical skills into a new product or piece of equipment. I am looking to collaborate with similar teams in the UK that are developing new  tools and products. You may need help in arranging the diagnostic elements for ease of use and displaying the outcome. The look and feel of the resulting product is essential to gain market acceptance.

Neil is looking to help UK development teams working on lasers for medical uses. Please contact through  info@devon3dcad.co.uk or on 01803 363 171.

Experienced Medical Product Designer Looking for Collaborative Partners

Medical Diagnostics are powerful tools in quickly understanding what exactly is wrong with patients.

As a Medical Product Designer I work with development teams enabling them to bring together their medical skills into a new product or piece of equipment.

I worked with the Abaxis teams in California who were developing their ground breaking Portable  Blood Analyser, the Piccolo. The work of the chemists, medical. electronics, control and mechanics teams was nearing completion but there was no plan of how to design the final product. I utilized human factors techniques to arrange the hardware to make a product that was easy to use and manufacture and  embodied the essence of a significant new medical product that had not been available before.

I am looking to collaborate with similar teams in the UK that are developing new diagnostic tools. You may need help in arranging the diagnostic elements for ease of use and displaying the outcome. The look and feel of the resulting product is essential to gain market acceptance.

Sheet Metal Design

Sheet metal design is one of the basic skills of a mechanical design engineer. I am a big fan of SolidWorks 3D CAD solid modelling software; it has a great suite of design tools specially for sheet metal design.  Here is a quick look at converting a solid part into a sheet metal part. This is not a masterclass in design, just a small, simple example of how good SolidWorks is at handling all the tricky bits of bends and folds.

For more sheet metal design go to the website of Devon 3D CAD.


Converting a solid part to a sheet metal part.

It is sometimes very convenient to start with a solid part, specially when you have already worked out the shape beforehand. Here is the finished part to get an idea of where we are heading.

Steel Cover DemoThe part is similar to a box with two flanges.

 

 

 

 

 

 

 

 

 

 

I started by modelling the basic shape as a solid. I always try to use geometry in design when I know that the part is symmertical, here about the Right Plane. The sketch is extruded a certain distance either side of the midplane.

Next I shelled the part using the wall thickness I had chosen for the sheet metal.

Using the ‘Convert to sheet metal’ tool I choose one face to be static and choose the edges that will have to folded to form a sheet metal part. The software tool makes a break between the faces and allows you have a lot of control over how the folded faces meet at the intersections.

You can see I have used an overlap feature where two faces intersect. The small gap between edges allow the part to be laser cut from the flat pattern.

 

 

 

 

 

 

 

Next I add a flange on one edge.

Then I mirror that flange about the top plane.

Then I add mounting holes by extrude cutting 2 holes in each flange.

The ventilation holes are made by cutting one hole then propagating it using linear patterns.

The first linear pattern makes one row of holes.

And the full number of holes is completed by patterning the row up and down the face.

Finally a cable entry hole is added on the bottom face.

And this is how the part is laser cut using the flat pattern from the 3D data.

Designs for Medical Industry from Devon 3D CAD

Devon 3D CAD has in-depth experience of helping start up businesses bring their product to market.

Incisive Technologies, in the San Francisco Bay Area, was developing a new dental laser machine for soft and hard tissue work and needed to get away from the “experimental laboratory” look and feel of similar equipment. I replaced the “gear on a 19 inch racking system” with a sleek, functional and user-friendly housing on castors that put the dentist in charge. We went from concept to market in a year.
