Engineering
Mechanical
Engineering is the core competency of Product Design. Due to this concentration
we tend to work on products that are somewhat more mechanically complex
than the work done by firms that specialize in industrial design and do
engineering as an added service. Our specialization in plastic part design,
FEA stress analysis, and injection mold design results in engineered plastic
products that are truly designed for production.
We
are a strong follower of the trend towards performing analysis of all
types earlier in the project . The output of even a rough analysis gives
the engineer input on which directions will most likely yield the results
he is looking to achieve BEFORE he spends time doing detailed work in
a direction that may be a dead end. This early analysis is supplemented
with computer based data acquisition to collect information on actual
conditions and to refine potential load conditions. Solid modeling in
Pro/Engineer
by Parametric Technology, Inc. serves as the basis for all of the product's
geometry, physical properties, and the interaction of parts within assemblies.
This Pro/Engineer solid model geometry can then be used as input for our
in house stress analysis performed in Cosmos/M
and Cosmos DesignSTAR
software. These
different operations are kept moving in the right direction by project
management skills developed by a combination of graduate level training,
hands on experience, and a solid engineering background.

Engineering
Visualization with Pro/Engineer Solid Models
We
do all of the actual mechanical geometry creation work using Pro/Engineer
solid modeling software. The clear visualizations that this product enables
allow even non technical people to contribute useful insights to the ongoing
design effort. We frequently export Pro/E models to the VRML format which
allows anyone with a reasonably fast computer to review and comment on
the design without the need for any special software. This technique works
well for getting early input rom non technical people who may be able
to contribute valuable user interface and market related insight.
Prototyping
in Software
Early
and ongoing functional analysis of the product as it takes form is used
throughout the engineering effort to guide us to the best solution by
plan, not by accident. Here Cosmos DesignSTAR is used to identify areas
were material can be REMOVED to reduce stresses. This part was analyzed
as part of an assembly and then the other assembly members were blanked
to allow a clear view of the stresses in this molded part.
Cosmos
uses our Pro/Engineer part and assembly models without the need to manually
create FEA models. As a result we can quickly test new design concepts
under various load cases without having to spend time or money building
prototypes for every design iteration.
Accurate
CAD Documentation 
We
use Pro/ENGINEER solid modeling software which keeps our 2D documentation
in sync with our latest solid models via a common database. Automatically
generates *.DWG or *.DXF files for users of AutoCAD or other CAD systems.
Since most of our projects end up in production the value of having an
accurate and up to date documentation package at the end of the project
cannot be overstated.
