Seat pans and backrests atomic number 18 plastic and tables attached to right armrests atomic number 18 20cm above the seat pans and in addition small to place taptops. Students opine about these chairs. According to our groups survey, 70 of 72 SM2 students suffer backaches after long hours of composing sitting on the chairs. Since tables be fixed, most students argon forced to bend down to write on the table for a long time, which puts a great strain on their backs and causes pain. Also, half students interviewed feel the flame of rooms is inadequate. Therefore, we have modified the TR chairs to solve these problems.2.Body2.1 Criteria for solutionThe modified chairs should meet the following requirementsTables are adaptable and easy to foldBackrests support the back of the dead bodySeatm ats are softTables so-and-so generate decrease according to indoor airying conditions Chairs are aesthetically pleasing make up is low.2.2 Description of the solution Our wonderchairs are like glossy silver eggs made from hard glass-fiber reinforced plastic (GFRP). Chairs have three foldable layers with two wheels at the bottom. The top layer with one side stuffed with rayon can be flipped everywhere as a backrest. The backrest is positioned at an angle of 100and stuffed with soft Rayon stuffing which supports the back of the body comfortably.The secondly layer serves as a table with a 22cm-radius, overcoming the existing defect of being too small which hinders comfortable writing.

Lamps are 25cm sticks in a groove on the table when not working. By rotating them 90we connect the lamps to a circuit and they start working.Tables consist of three layers. The first is made from transparent GFRP to allow maximum light to pass through and be absorbed and turned into electricity by the photo-voltaic panel in the second layer. The second layer also contains a light sensor detecting lighting condition and consequently adjusting the intensity of the lamp light. Powered by photo-voltaic panel, the lamp produces proper light according to the indoor illumination conditions. This ensures appropriate room lighting. The third layer is opaque GFRP to strengthen the table. The self-lighting system utilizes solar energy to create light, so it is energy-saving and environmentally-friendly.2.3 CostThe wonderchairs have low cost and predict great potential for mass use in colleges. unrivalled chairSG$ 1 (Rayon)1SG$ 1 (Aluminum lever+wheels)2SG$ 2 (GFRP) 3SG$ 2.5 (solar panel)4SG$ 0.1 (light sensor)5SG$ 1 (lamp)6Total SG$ 7.513 Conclusion Our wonderchairs are targeted at reducing present NTU TR chairs discomfort and harm to the human body.
