Abstract

This research and development project invents a new product and product category by combining two different products that were previously usually never put together into a single product to solve a modern-day problem involving the home environment. This product combines a furniture product and a loudspeaker product to save space and reduce room clutter as well avoid the trade-off of compromising the aesthetics of a room to achieve great sound quality in the home environment. The project goes through the entire process of research, design and fabrication of this product step by step following the normal design and development process by Ulrich. The user requirements for the product were acquired through secondary and tertiary sources. In the concept design phase, many different furniture and loudspeaker combinations were explored guided by a morphological chart but using Pugh’s evaluation and weighted decision matrix, the concepts were narrowed down to one combination which was the coffee table and subwoofer. The coffee table subwoofer hybrid design was chosen due to the best balance of sound performance, practicality, and in-house location compatibility. The appropriate ergonomic considerations were made during the design of the cad model of the concept. The most compatible materials and parts were chosen before beginning the cad design process to aid and guide the final cad design and finally a computer analysis was performed on the final cad design model before proceeding to the prototype fabrication process. The computer analysis process is shown and explained in detail to relay the complexities and nuances in the designing process. The fabrication process is shown in brief and subsequently the finished prototype has acoustic optimizations performed on it before proceeding to the usability testing with actual users. 10 respondents were chosen to test and rate the product and the results were tabulated to give an idea of how well the product performed. The results show good to excellent results proving the project was a success as it hit the expectations set out in the research objective.
