dened. Then the basic parameters of size, weight, shape, fastening, controls, and sterility can be
met. During this process, the secondary parameters of power and operational temperatures, etc., can
be derived from the design and optimized to fall within acceptable limits.
Three-dimensional mechanical modeling software can be very useful. Inexpensive off-the-shelf
software can allow the designer to enter the basic mechanical components of the design and render
the design in color. The designer needs not have to stop only at rendering images. If there are mov-
ing parts, it is possible to create a video of the parts in motion. This kind of effort usually helps
optimize the design before any resources ...
