When industrial instruments manufacturer Testo asked PDD's Hong Kong studio to revamp the design of its existing ventilation and air conditioning (VAC) device, a number of challenges arose.
For example, the high-end product had to reflect the brand's heritage and honour a number of established form guidelines. At the same time, the unit couldn't look dated and needed to offer a vision for future products. Used in harsh industrial environments, the device also had to be robust and capable of measuring flow, temperature, humidity, pressure, light, radiated heat, turbulence and CO² emissions.
PDD's designers had very little freedom to amend the unit's proportions, given its strict internal structure and electronic requirements. This also limited the choice of materials, which had to be injection molded and stamped metal elements.
For the external aesthetics, Testo wanted a high-spec finish and impeccable parting lines to distinguish the unit's separate functional areas. The design team also had ergonomic considerations, particularly the fact that technicians using the device may wear gloves, goggles and other protective clothing. To cope with the unit's multi-functional requirements, the team needed to consider the compatibility of multiple digital probes that users could easily interchange according to the application.
Although PDD designed and tooled the unit in the Far East, it is manufactured in Germany. Being in Hong Kong allowed the team to meet the toolmakers and other suppliers regularly, ensuring the intent behind the design was not "lost in translation".
PDD breathed new life into an established product and proved the ideal link between the R&D capabilities of Testo's headquarters in Germany and the manufacturers in Asia.
PDD has completed its planned transition to the latest version of this rigorous international quality assurance standard for medical devices, building on the success of earlier transitions and successful audits to the FDA 21CFR Part 820 in 2015.
It’s been a great start to 2016. The first quarter is not yet over and already PDD has 3 new prestigious design awards to its name. PDD’s work with the health & personal care brand Swisslux and the Zyliss kitchenware brand has been awarded with Red Dot design awards. This was followed by a German Design Award for the Testo 870 Thermal Imager.
