This is a consumer product concept that I have developed in details for an electric incense burner. The device uses 2X li-ion 18650 batteries and a ceramic heating element. For user interface a push button, 3X LED lights, and a haptic disc LRA are considered. The user is able to input their desired incense, close the lid (snaps nicely to the top using 4 neodymium magnets), and turn on the device while enjoing a hassle free smooth experience and a delightful fragrance. In terms of manufacturing plans, there are 5 parts that are designed to be produced using Injection moulding, and one part each using die casting, sheet metal, LIM, and CIM technology. It is critical to place the heating element on a material that can handle high temperatures such as ceramic (olive green part). The silicone part (black) is designed for easy removal and placement for routine cleaning of the metal plate (white). All parts were designed according to their respective manufacturing processes best practices. In terms of assembly, the plan is to attach the parts to the inner frame, slide into the device and secured with two screws on the bottom. In addition to the CAD models, a simple clay model was built to confirm the feel and grip of the device. Potential future steps for progress could be a thermal study in terms of device temperature investigation and CFD study for confirmation of incense flow and dispersion in the air.
