Bison Airlighter model 420 designed by Atus Design LLC

Few years ago Atus Design developed a successful item – Bison Airlighter model 520 for one of its clients, “The Bison Company”, subsidiary of Infora, Inc. Now we proudly announce release of the next generation of Bison Aitlighter – model 420. It is as sturdy and as well design and built as model 520, but it is also somewhat different that its predecessor model Bison 520 and has few features dropped and some others re-designed. For example, it is considerably smaller in size, it still has powerful flame using butane which is still stored in its handle. It also offeres same poerful air blower for spreading that heat. But it does not have USB port and re-chargeable batterisl inside. It rather offers user to use his own standard AAA batteries. There is also no more flashlight. Those of you, BBQ enthusiasts who also love to have beer while cooking meet, do not worry – bottle opener which doubles as a hanging hook is still there.

The Airlighter 420 is the faster, cleaner, and safer way to light BBQs, campfires, wood fireplaces and just about any other fire.  It is also a cooking tool for searing meat, or caramelizing sugars and more.

Patented Bison Airlighter Designed By Atus Design LLC

Project was ordered by company Infora, Inc. with offices in Sweden and in New York. Infora was distributing for years product "Looftlighter" which worked from 110 Volts wall electricity. "Looftlighter" was a tool for starting fire in BBQ grills, fireplaces, camfires and so on. The problem was that it was powered through thick cord. For using it outside in a backyard, campsite or hunting or fishing spot one would need to have either electric outlet or powerful generator and electric extension cord. 

Infora asked Atus Design to design and engineer a truly portable tool with refillable butane tank, adjustable angle handle and additional comfort features, such as flashlight, can opener, USB charging port and butane re-filling port. Atus Design was also to design layout of retail box for the product and its accessories.

Initial steps start on paper and result in multitude of hand sketches, study of analogs and product related to the one we are designing. Handheld devices must meet certain ergonomic requirement and be comfortable for as many different types of users as possible - men, women, older and younger adults, people with large and with small hands. Right after hand sketches we go to solid foam sculpting and evaluating various rough shapes and rough features.

Next stage - modeling in 3-D CAD. Here we also create several models for customer's evaluation. Some are printed on 3-D printer in order to give client a chance to have sensory evaluation and better understanding of size and proportions.

Important feature that had to be designed and implemented in Airlighter was child safety. While it had to be reasonable easy for adult to use Airlighter, it had to be designed in a certain way which would have prevented a child to ignite it. So, an additional sliding safety button was introduced, which had to be shifted to one side before main ignition button could activate flames.
