Teams for Product Design and Development
Neil Tischler, Principal

I have been an independent product design consultant from 1978 to my retirement in 2014. Over that period I provided quality mechanical engineering, electronic packaging and project management services for new products in internet electronics, commercial electronics, and medical devices. Clients benefitted from my early background as a stress analyst, my eye for detail, and knack for creating products that are easily fabricated, assembled and serviced. Working closely with each client's staff, I treated the vital issues of structure, component placement, wiring, cooling, EMI/RFI isolation, manufacturability, and user ergonomics to ensure well-integrated products.

Here is a sampling of career projects...

Convergent Dental Solea

Solea Dental Laser by Convergent Dental of Natick, MA, is the first CO2 laser to be cleared by the FDA for hard, soft, and osseous tissue procedures, virtually eliminating anesthesia and blood from operative dentistry. The dentist saves time... no injections, no waiting. He can work in multiple quadrants, address cavities discovered during cleaning in the same appointment, and do many soft tissue procedures directly. Because of its unique computer controls, patients experience no vibration, no noise, no numb jaw. Brought to market in mid 2013, this device has the potential to change the way dentistry is practiced... worldwide!

My primary responsibilities were to create the wheeled cart that houses the laser and its optical, electronic, and pneumatic components. With excellent coordination from electronics consultant Bill Groves of Sachem Design and from members of the Convergent Dental design team, I grouped components into modules for assembly inside a sheet metal structure, shielded the electronics for interference, and established a cooling scheme. Industrial designer Hern Kim of Hernetics, LLC joined me to shape the overall design with pressure-formed panels that met the aesthetic and ergonomic requirements of this chair-side device.

The intense two-year team effort that created this highly acclaimed dental instrument also yielded several major awards:

  • Medical Design Excellence Award - Gold, best dental instrument or product - 2014
  • Dr. Bicuspid Award - Best dental product of the year - 2014
  • Popular Science - "top 100, best of what's new" Award - 2014
  • Edison Award - Gold winner for Innovation - 2015
  • PRISM Award - Finalist - 2016


Wildlife Acoustics Song Meter SM3
Song Meter SM3 is an advanced professional bioacoustics recorder by Wildlife Acoustics of Concord, MA. Its cast aluminum enclosure is fully sealed and ruggedized for reliable wildlife field recordings of up to 260 hours. This device allows you to simultaneously record any combination of avian, terrestrial, herpetological and marine life. In a project led by Origin Product Development of Maynard, MA, my role was to create accurate 3D CAD models of the physical components and to collaborate on the design and layout of the enclosure. We focused on designing water-tight seals everywhere, optimizing the internal wiring for manufacturing assembly, ensuring robust component mounting against major impact and vibratory loads, and providing improved enclosure field mounting options.
