Traditional ceiling fans are an energy-efﬁcient way to regulate the temperature of a room, but their design has remained unchanged– they rely on unintuitive chains to act as controls, are a hassle to clean, and they are an eyesore in most rooms. Recent technological advances and an increasing demand for energy- and cost-efﬁcient, smart home appliances made it possible to disrupt that industry. The Coanda is a ceiling fan with no visible controls or blades that comes in a smaller package than conventional fans.
UNIQUE PROPERTIES / PROJECT DESCRIPTION:
The Coanda is a smart ceiling fan that connects to smartphones and learns users’ preferences, communicates with smart thermostats to ﬁnd an optimal settings, turns itself on or off depending on location, and regulates intensity and airﬂow direction. The design is inspired by air pressure ampliﬁers and internal fans found in laptop computers, and uses electromagnetic motors to propel the fan blades, with built-in LED-powered light ﬁxtures that provide bright illumination at low energy costs.
OPERATION / FLOW / INTERACTION:
The Coanda controls the pressure and direction of air ﬂow caused by the fan blades to provide an optimal output with smaller blades than traditional fans. The design is horizontally symmetrical so that airflow direction allows for thermal destratiﬁcation in winter months, pushing warm air so it ﬂows to the bottom of a cold room. App connectivity allows users more control the fan's speed from 0 to 100%, while the fan’s learning features enable it to provide optimal comfort and energy efﬁciency.
PROJECT DURATION AND LOCATION:
The project was started in January 2014 in Savannah, Georgia, United States. There are currently no plans to release it to the market.
FITS BEST INTO CATEGORY:
Home Appliances Design
PRODUCTION / REALIZATION TECHNOLOGY:
The device is made of mostly recyclable and reusable materials, mainly aluminum, glass, and dark grain wood.
SPECIFICATIONS / TECHNICAL PROPERTIES:
12” x 35” x 35” not including adjustable down rod and ceiling base.
Temperature control, smart devices, ceiling fan, ventilation.
The Coanda was designed after researching the physical properties of air ﬂow dynamics, particularly the Coanda effect and Bernoulli Principle, as well as after conducting primary and secondary research on the opportunity and demand for connected appliances and smart temperature controls.
The biggest challenge while designing the Coanda was ﬁnding an original, effective method for air circulation with no visible blades without sacriﬁcing energy efﬁciency and intensity of air ﬂow. This was overcome by drawing inspiration from laptop computer fans and automated batting cages, among other things.
