1. INTRODUCTION First-year engineering students at Carleton University have been given the task of creating an attachment or replacement table that will enhance their ability to engage in lectures. We had three initial sketches during the design process, and from each one, we chose the most functional elements to create the final concept. To meet the goal of being able to readily detach the item, we chose to stick with few to no screws. Moreover, to meet the criteria that we set we needed to create a piece that was safe, sturdy, and reasonably priced. Finally, we were able to develop a model that complied with the predetermined standards and specifications. 2. DESIGN CRITERIA 1. Cost (20%): Around 60 CAD 2. Safety (30%): Curved corners on the exterior, the cup holder was not placed on the foldable portion of the surface. ○ Additionally, we made a portion of the surface fold upwards to make a passageway easier for students. 3. Reliability (10%): Should last for 7-10 years 4. Performance (25%): ○ Very easy to attach, simply open the foldable table in your chair and place the surface above it to set it up. Could be taken off in 30 seconds. ○ The materials used are of high quality, and the price is reasonable. ○ It is really productive. 3

5. Durability (15%): It’s fixed in position because the surface sits precisely on top of the foldable table. 3. DESIGN CONSTRAINTS PHYSICAL SPECS Wood Little amounts of wood to be used, to stay on the sustainable scale. Moreover, high quality of wood is used to make it more durable and safe. Screws Little to no screws, therefore, we chose to only use Long hinge screws for the hinges. Metal hinges Hinges are used to provide a safe experience that allows the piece to bend upwards, allowing people to pass. OPERATIONAL Crew Members 2-3 crew members would be needed to create this project. ECONOMIC Cost 50 CAD, which is a reasonable price. 4

In concept 1, the shape of the piece was the weakest aspect, therefore we attempted to strengthen it in concept 2. However, concept 2 did not provide adequate extra space and had numerous missing features. The closest to our final concept was concept 3, yet we failed to think about how people would pass, forcing students who were using the piece to remove the entire piece in order for other students to pass. As a result, in the final concept, we stuck with the main idea in concept 3 but instead made the top part bend upwards. Moreover, since the original table is not made of a material that attracts magnets, we had a problem with the magnetic attachment in all 3 concepts. Therefore, we decided to cut out the exact shape of the original table on the back of the piece to sit right on top of the table and be sturdy. 6. PRELIMINARY DESIGN SPECIFICATION 8
