Can something as industrial and rugged as a transport trailer refrigeration unit meet customer performance needs and look good too? Why not, thought an energetic team of engineers and designers at Thermo King® in Minneapolis, Minn. So they threw out some of the old conventions; looked at the challenge in new ways; and discovered that style sells – even in the transport refrigeration industry.
Thermo King, a unit of Ingersoll-Rand, was so delighted with its new product that it entered the design in the Industrial Designers Society of America/Business Week® IDEA2001 competition. The IDSA® was impressed, awarding Thermo King a Gold IDEA for the SB-200/SB-300 series of transport refrigeration units. The judges found Thermo King designers “were daring enough to make a bold statement with design, yet smart enough to improve on the more utilitarian features required by end users.”

Tom Flanagan, Thermo King Industrial Designer, believes StudioToolsTM had much to do with the success of the new styling direction. He explains, “The SB-200/SB-300 Series was a complete departure from our traditional market image. Due to significant changes in new tractor styling (e.g. Freightliner, Ford and Kenworth) in recent years, we sought a highly streamlined and organic form from day one.
“After importing the necessary reference geometry from Pro-Engineer, I was able to quickly generate a number of possible design schemes in Studio. It’s such a fluid program that I could immediately begin creating some basic design surfaces to stimulate some early excitement for a new design direction. For me, these are the strongest attributes of StudioTools: ease of use, to create preliminary designs as quickly as possible, and excellent rendering tools to help build a rapid consensus. I usually don’t sketch much first; I usually just go straight into StudioTools because there are few barriers in the program to my creativity.”

This open-ended approach to design helped Flanagan create a sleek, organic design, with soft edges and aerodynamic shapes that complement the latest tractor designs, including a radical new grill design with elliptical openings in place of the company’s traditional rectangular-grid pattern. In addition, the use of injection-molding made it possible to manufacture the grills in a wide range of vibrant, custom colors; as well as chrome plating for the “owner-operator” segment of the market. So customers can either stick with the standard colors (black, gray or white) or, alternatively, bust right out of the mold and show some personality!

“I’m a big fan of both organic design and color,” says Flanagan. “Even in a market as utilitarian as ours, I believe that people still respond emotionally to a more contemporary look. Our new product shows that, as long as we can deliver on superior function, there is no reason why the form itself should not be equally desirable.” Fine Tuning by Consensus
While up-to-date styling was a major priority, overall performance was of yet greater import to the Thermo King team. They wanted to make significant improvements in “pull-down” — the ability to drive the temperature of the trailer to the set point in the shortest possible time; to provide greater overall cooling performance for deep-frozen applications; to improve serviceability of the unit; and to reduce the perceived noise level. In order to address these physical requirements along with outer package styling goals, several departments within Thermo King crossed ideological boundaries and began working more closely together.
Over the following months, as form and function issues were identified and improved upon, Alias® StudioTools models and renderings were evaluated by design engineers, drafters, manufacturing engineers, and marketing professionals at Thermo King. “That’s the great power of StudioTools,” explains Flanagan. “We can work together on a virtual mockup of a new product and still have full confidence in the downstream manufacturability of the design. In addition, because of the “construction history” in StudioTools, we can tweak here and there without having to rebuild the entire design from scratch, and resolve clearance issues in a very short space of time.”
This interdisciplinary approach led to a number of innovative technology solutions. The new grills not only added a stylish look to the unit, but were also designed to minimize high frequency, directional noise. A new “Whisper Quiet” noise package reduced decibel levels as well. One customer even reported recently that his drivers were arguing with each other about who gets to operate the new SB-200 series-equipped rigs because the difference in perceived noise level is so significant over the previous generation. New Day for Thermo King
Today the new Thermo King SB-200/SB-300 refrigeration units are easily identifiable, from the sleek grills to their whisper-quiet operation. Customers appreciate the significant increase in temperature control performance, coupled with the new level of serviceability. Moreover, they also praise the overall style and dramatic use of color. “We’ve transformed the image of Thermo King,” claims Flanagan, “and StudioTools made it possible.”
