Conceptual Design of Storable Home Furniture

An ergonomically based space-saving and multifunctional product for home users is presented in this project, which aims to promote natural sitting postures and to reduce the risk of musculoskeletal disorders. The furniture was constructed using Malaysian anthropometric measurements, and the measurements were selected according to its respective criterion of the anthropometric parameters. The desk height, seat height, depth and width of the chair are the main priority for anthropometric measurements. In the preference of natural sitting position with a low risk, RULA or Rapid upper limb assessment were performed. Market research on home furniture related to current market demands and current technology in specific furniture functions has been conducted. Concept designs have been developed by using Morphological Chart, and the most suitable concept is chosen by using the Pugh matrix. Solidworks software was used in developing the selected 3D CAD drawing concept. Solidworks simulation has evaluated the selected material to assess the safety and durability of the furniture. The main concerns in this simulation were the displacements, strains, and stresses of furniture designs subject to internal and external loads. The simulation results have shown that the furniture will be safe and able to withstand load upon 150kg. A 1:1 scaled prototype was then developed to represent the final outcome for the simulated design.
