The Tough Table Milestone presentation Andri Karl Tómasson, Helgi Sigurður Pálsson, Ingvar Karl Hermannsson & Stefán Jón Hrafnkelsson Department of Science and Engineering (TVD) Reykjavík University March 11, 2019

Introduction • The tough table • A sturdy, tough dining table which can be changed into a working bench with a flip of a plate • The solution for people to maximize the usage of their homes • Suitable for all-size households • Axiomatically designed Andri, Helgi, Ingvar, Stefán (RU) The Tough Table March 11, 2019 2 / 10

History and background [1] • No dual purpose dining tables • No dining tables rotatable about the horizontal axis • No previous patent found on rotatable tables [2] Andri, Helgi, Ingvar, Stefán (RU) The Tough Table March 11, 2019 3 / 10

Design: Bill of materials (BOM) What materials are needed for this project? • 1 x Solid Oak board 40.000 kr • 1 x 30mm Low carbon steel pipe with 27mm ID 2400 kr • 1 x 27mm Low carbon steel axle 3000 kr • 2x Low carbon steel flat bars for the legs 7300 kr • 1x 1400x1000x1mm steel plate 3900 kr Andri, Helgi, Ingvar, Stefán (RU) The Tough Table March 11, 2019 7 / 10

Status Done • Sketches and cad drawings • Stress analysis with Inventor Problems • Problem solving for stability • Problem solving for assembly • Looking in to upscalability Andri, Helgi, Ingvar, Stefán (RU) The Tough Table March 11, 2019 8 / 10

Tasks remaining To further develop the table it would be useful to look in to making a prototype or making a fully functional computer model. Further more look at the cost vs the budget. Andri, Helgi, Ingvar, Stefán (RU) The Tough Table March 11, 2019 9 / 10
