Tsann Kuen Group is making good use of Nielsen Innovation’s understanding of European culture, as well as the design firm’s engineering advances, to help it develop highly efficient vacuum cleaners for global markets.
With the utilization of patented Wi-Flow technology, Nielsen Innovation and the Tsann Kuen Group developed a line of vacuum cleaners that achieve the same cleaning efficiency as a traditional 1,500-W canister with only a fraction of the energy consumed.
After more than 5 years of development, France-based Nielsen Innovation, a product development company, was ready to bring its Wi-Flow® vacuum cleaner technology to the consumer appliance market. Wi-Flow technology is an optimized suction system for vacuum cleaners, employing solutions that favor high airflow instead of high vacuum to produce the same cleaning power as a traditional 1,500-W canister vacuum cleaner with only a fraction of the energy consumed—100 W for cordless models, and 150 W for corded.
In the development of the Wi-Flow technology, Nielsen Innovation challenged the very concept of how a vacuum cleaner should function; every aspect, from the nozzle and air ducts, to the filter and motor, was overhauled to reduce pressure drop and increase airflow. Henrik Nielsen, founder of Nielsen Innovation, tells APPLIANCE, “What I often find in mature industries is that people forget to ask themselves why a system actually works, thus preventing them from challenging the basic technology. It is more difficult to imagine that something could be done differently in the beginning than finding the right technical solution for improvement.”
was subjected to independent design tests by SLG in Germany according
to IEC60312, Vacuum cleaners for household use—Methods of measuring the
performance. The tests confirmed that a 100-W Wi-Flow vacuum cleaner
achieves the same pickup performance as a 1,500-W corded canister
vacuum on most carpet types, with results surpassing those of the
traditional canister when tested against pet hairs, fibers and threads.
With Wi-Flow technology conserving approximately 90 percent of the
electricity used to run typical vacuum cleaners, the company estimates
that this could hypothetically save more than 5 billion kWh for Europe
A former colleague put Nielsen in contact with the Tsann Kuen
Group (Tainan, Taiwan), a mainly private-label manufacturer and
developer of small consumer appliances. The former colleague had worked
with Nielsen when he had held a position at France-based
Moulinex/Krups, one of Tsann Kuen’s customers. That contact helped
start a relationship between Nielsen and Tsann Kuen, and the appliance
maker eventually agreed to buy the license agreement for the vacuum
With an optimized suction system, Nielsen Innovation and the Tsann Kuen Group hope to bring powerful, energy-efficient vacuum cleaners to consumers around the world. The companies developed a line of vacuum cleaners said to achieve the same cleaning efficiency as a traditional 1,500-W canister with only a fraction of the energy consumed.
The partnership required an intimate level of
cooperation, with Nielsen Innovation supplying the technology as well
as aesthetic and critical parts design, while Tsann Kuen’s engineers
handled development, prototyping and manufacturing of the plastic
parts. First, Tsann Kuen asked Nielsen Innovation to design a prototype
that employed Wi-Flow technology. After the success of this vacuum,
dubbed the Libero®, Tsann Kuen had Nielsen Innovation design a line of
prototype vacuums that would allow it to demonstrate the technology to
appliance OEMs around the world.
Kota Chang, vice president, Tsann
Kuen Group, says the greatest development challenge was the transfer of
technology. Since Wi-Flow is proprietary technology, much time and
energy had to be put into educating the research and development
engineers at Tsann Kuen. “The transfer of technology requires a lot of
discussion and testing; everything must be communicated clearly between
the designer, engineer and manufacturer,” he tells APPLIANCE. A similar
learning curve was required for the appliance maker to integrate
Nielsen Innovation design concepts, as well as for the integration of
Wi-Flow technology into those design concepts.
Chang believes the
benefits of the partnership go beyond the new vacuum technology. “A
European design firm reflects European culture; they know better than
we do in Asia the habits and culture of their market. This way, we can
better appeal to our wide customer base.”
At the moment, a Nielsen
Innovation-designed line of Tsann Kuen vacuum cleaners with the new
cleaning technology is being prepared for the manufacturing testing
phase. Appliance OEMs from all over the world have been approached with
