Thanks for that shot of reality! As you may or may not know I have developed
Digital Jeweler, a server side CAD configurator for customizing core jewelry
designs. The mechanical aspects of each ring are pre-engineered. The variables
for the user are center and side stone dimensions, finger size, metal types,
stone types, and other aesthetic features. The only thing that really affects
the geometry of the piece are the stone dimensions and finger size. The rest
are cosmetic attributes for the CAD engine to render appropriately and to create
pricing and a bill of material.
The user can dictate the aforementioned variables and a new CAD geometry is
created in about a minute. The user is able to view the customization in both
pre-positioned JPG and also VRML. The significance of this customization has
more to do with a manufacturing paradigm shift than in the user being able to
customize the ring. Whereas typical mass production limits the manufacturer to
pre-creating a series of master models and molds for a particular design, the
flexibility of that design being dependent on the number of permutations the
manufacturer chooses to make, Digital Jeweler allows for almost infinite
variation between center stone, side stone, and finger size permutations.
The reason I brought up this thread is that some of the jewelry designers using
the system are asking for more flexibility for creativity. To add this
flexibility would be to allow the user to create both mechanically proper and
improper designs. I have chosen to limit the flexibility in order to guarantee
a proper result as I see more value in dummy proofing the output of CAD/CAM than
in creating yet another CAD software that must be manually operated by a
I don't think you can have a system that allows for both guaranteed results and
unlimited flexibility as the rules for proper mechanical jewelry design are too
complex. I was just thinking about how much further I could go with design
flexibility given the precondition of a guaranteed good result. There is more
but then I began to wonder if too much flexibility could have a negative effect
on the consumer.
I do have to argue with one point you made.
"Besides, a totally customized product won't sell if it's 10% more expensive
than the standard item...;)"
Custom jewelry routinely sells for more than mass production. Your point is
accurate as to the size of the custom segment but not to it's existence. This
may just be a niche where this is true, I don't know.
