Chat with Zapp

Thu, 09 May 2013 17:59:00 +0700

Me: How do you see the direction of your design in next five years.
Zapp: I'll be heading for classic, instead of chase the trending. I also seek for a chance to deliver more material options, as well as new applications of technology.
Me: Do you still see "simplicity is timeless" valid on that day?
Zapp: Yes, I never pretend to become someone else.
On an afternoon conversation at Plaza Senayan. Zapp is a graphic and product designer lived in Bali, where he spends most of his time curating furniture from wood and rattan.

Modeling Metric Threads

Wed, 01 May 2013 18:51:00 +0700

This is an attempt to create M6 metric threads for both external (male) threads and internal (female) threads. The basic procedure is by using rail revolve command, with precised measurement for profile curves, rail curves, and axis.

Step to create:

Set the document. Put value to grid extents: 100 mm, snap spacing: 0.1 mm.
Create the profile by using ISO rules for metric threads. Open thread on Wikipedia.
We will model M6 threads for both external (male) and internal (female).
Useful terms: Dmaj (Major Diameter) is set to 6 mm (defines the maximum size of external threads, and minimum size of internal threads), pitch is set to 1 mm, and height is set to 0.866 mm (equivalent for 0.866 x Pitch).

Roll over to right viewport.
Create the H curve (red) for 0.866 mm.

Create the P curve for 1 mm, perpendicular to H curve. Use midpoint snap to positioned it.

Create a polyline to connect three points (1 - 2 - 3) from H and P curve.

Create a trim curve for 0.10825 mm (= H/8).
Create an H/4 line, equivalent as 0.2165 mm.

Create a P/16 line, equivalent as 0.0625 mm.

Create a “rounded curve” as illustrated. Use curve command with degree set to 3. Shift the degree of the curve to 7 (see black curve) afterwards.
Notice that two rounded curves needed, as “profile” for external and internal threads.

Copy all curves and send them to separate layer. Trim the curves one another, then join them to get a profile curve.
Offset the curve for 0.1 mm outward, to get a profile for external thread.

Trick: notice that valleys should have rounded profiles for both external and internal threads. In other word, clipped peak of a thread should mate to rounded profile of the valley. This could be done by offsetting rounded profile to 0.1 outward, then trim offset line with profile curve for external threads. Thanks to Pascal, for pinpointing.
Offset joined curve 0.1 mm outward. Change colors for both curves to differ them one another.

Create major diameter (Dmaj) for 6 mm and axis curve by 1mm from base plane in z direction.

Move created profile curve to quadrant of Dmaj. Using midpoint snap command to previous H/8 line. Midpoint of H/8 lines will be used as “base” to DMaj.

Run helix command. Set mode into turns, set turns to 1, and pitch to 1, and reverse twist to no. Use previous axis curve as start and end, and use midpoint of external thread curve as radius point.
Repeat helix command, and this time snap the radius point into midpoint of internal thread curve.
Rails for internal and external threads are ready. Changed the color to avoid mistake when rail-revolving the profile curves.

Run rail revolve command. Select profile curve for external (male) thread, and use the adjacent helix as rail. Use axis curve as start and end point.
Re-run command for internal (female) thread.

Voila! We now get basic surfaces for internal and external threads. Differ the colors to classify them. External (male) threads in blue, and internal (female) threads in green.

Copy the surface as many as needed, by using endpoint snap. Join them respectively.Name both polysurfaces, to keep geometries manageable.

Create trim lines to cut away top and bottom parts.

Run cap command to make external threads.
Create a cylinder then run trim command with using created thread as trimmer to cut away the center of cylinder. Join the surfaces together to create an internal threads.

Done. :)

Bonamana Chair (Work In Progress)

Thu, 18 Apr 2013 17:29:00 +0700

Digital development of a multi-purposed chair, created by industrial designer Iqbal Musthafa. The basic concept of the design was by creating a plastic shell which will be used as “platform” to create various types of chair, including swivels, sledge base, and four-legged.

The seat and back are combined into single part that will be made by plastics (probably Poly Propylene or Poly Amide). There is an ornament at the back, which looks like a scattered square.

This phase is an engineering study before the concept goes into reality. A complete check-up will be done, including study of the dimension, overall proportion, and thickness of the product. Analysis of the elements (FEA) will be done as well to test the design, whether or not it can resist stresses and human body-weight.

The modeling phase was started from scratch, as the basic principal of the design: curves generate surface, surfaces generate solid. With, of course, points as helper.All the curves were “mouse-drawn”, and had minimum control points to help the next stage easier.

The next phase of this digital process is creating the prototype, which can be done in various techniques. One of the most plausible techniques is by using CNC machine, that will generate a physical model accurately, fits with the geometry’s data.

An old test case of prototyping can be found here.

Details of "Omega Bracket"

Thu, 18 Apr 2013 16:21:00 +0700

I am currently developing a very simple component which seems to turn in to be a long way process of designing. This component has been posted previously, and had some continuous refinements in the making.

The basic function of it is very simple: to clamp a rectangular pipe, by using a pre female threaded top part, and holed bottom part. This idea could be applied into many cases, but as a “test case”, this is used to tighten two separate pipe as table structure.

There are shifts from the old design to new one, and in general there are three revisions made so far. This process can be considered as Kaizen activity to find the best solution.

The first design had a cube based form, and the second one did look like a flying saucer (above). The third and final design of this component looked like a trimmed cylinder, and still has the same purpose and structure.

Within this development process, I am using Rhino 3D software with the latest version (5.1.20927.2215). The improvements in the software itself were very impressive, in my perspective.

One very important new feature was definitely the “new” (previously developed on beta phase) “shell” command for creating a consistent wall of a component. This couldn’t be done easily in their previous version, but the new one served this feature nicely.

Above illustrations show how the command works. The logic of the command is initiated by removing one or more face (s) (surface (s)) within a polysurface, then it will simply attempt to create a wall with given thickness.

This command is very helpful on overall designing process, as it shorten some modelling commands and time to create the thin wall if it is done “manually”.

All of the new commands and features can be found in the documentation section.
