Updating Products with Cheshire Engineering Corporation
Update or Replace Legacy Products
Cheshire's over three decades in the business of product design and
development experience gives us the techonlogy background to help you update
or replace your legacy products.
The sage advice "If it ain't broke, don't fix it" keeps many legacy products
going year after year. But eventually the definition of "broke" comes into
focus: is the legacy products still manufacturable? Is it still
One of the things that often breaks legacy products is the Bill of Materials
used to manufacture them -- the price and availability of the components. This
can easily become "the" driving force behind a need to update or replace a
legacy product. Cheshire can help your purchasing department review
alternative parts to determine which are suitable replacements. In some cases
we can re-design portions of the circuitry to use more available parts to
provide the same function.
Legacy products are often based on older or proprietary connectivity
solutions, or no connectivity at all. For example, a legacy factory
instrument used a proprietary protocol on an RS-232 connection to allow remote
setting of parameters and collection of data. Cheshire designed a connectivity
solution that bridged that proprietary connection to Modbus -- an industry
standard solution. And we did it in a small circuit board that physically replaced the
RS232 transciever chip of the legacy product -- no external boxes and no
modifications to the legacy product, beyond replacing one chip -- a 16-pin DIP which was
already in a socket!
This allowed our client to roll out a new model of the legacy product, with a
desireable new feature, at minimal cost. This "new" model became the sales
bridge to keep the product line viable until a replacement model could be
brought to market.
