Question-2 (10 marks: 10%): (CLO3:100%) Human Factors Indicate if each statement in the following table is True or False Statement The goals of ergonomics are to ensure comfort, safety, and quality of products. The goal of considering human factors in the engineering design is to fit human capabilities to the machine. The first step in acoustic treatment is to erect barriers between the source and the listener. Designers should use anthropometric data to design products to be suitable for the 50 percentiles of users. In selecting the buttons to be placed in the middle of a TV remote control, the buttons that have the highest frequency of use and time (duration of use) should be placed in the middle. In a car, the force needed to adjust the seat belt is an example of physiological factors. The size of the engine in a car is an example of anthropometric factors. A remote control is curved in the middle to allow users to easily access buttons in the middle. This is an example of psychological factors. The temperature of air inside a car is an example of physiological factors. The position, size, and color of buttons in the instrument panel of an airplane are example of psychological factors. Question-3 (25 marks: 25%): (CLO2:100%) Need analysis and problem formulation Toys have gained increased use in the contemporary world. The toys are designed not only to entertain but they also promote intellectuality and enhance emotional or physical development. In this project, it is required to design a toy with a high educational value to be used as a symbolic learning tool for children. The toy must be attractive to and suitable for children, aged 3 to 6, both male and female. As parent buys the toy it must also meet their requirements. After conducting the need analysis by asking important questions related to the targeted product, the designer identified the required needs shown in the table below. A. Complete the table (next page), by classifying the design requirements using the appropriate category indicated by the A-E symbols shown below. one single choice should be made for each item (Most appropriate) [18 marks] Tor F

[A] Problem Objectives; Constraints; [C] Criteria; [D] Design specifications. # Statement ABCD 1 Design a toy with a high educational value to be used as a symbolic learning tool for children aged 3 to 6, both male and female. The overall size of the toy is limited to 300x300x200mm to fit on a coffee tabletop. 3 The toy should have a pleasing appearance and attractive features to both males and females. The toy should encourage the child to learn and develop new skills for instance; hand eye coordination, learning letters and words. It should be possible for a young child to play with the game by himself/herself or with parents and other children. 6 The toy should have high aesthetics (attractive). 7 The toy should cost a maximum of 50 Saudi Riyals to manufacture. The toy should have a high strength to withstand the harsh use of a small child. 9 The toy should preferably be manufactured in different colors. 10 It should be possible to expand the toy so that it can be made more complex as a child gets older. 11 The toy will be easy to clean after use. 12 The toy should satisfy American and European safety standards. 13 The toy must meet the parents' requirements. 14 The toy should be made from recycled material. 15 The toy should be low cost. 16 The toy should develop and satisfy a child's curiosity. 17 The toy should be easy to make. 18 The toy must be safe to use and does not have sharp edges. B. Using the table below, identify which of the following statements is a "Must" or a "Want"? [2 marks] JA] Must; Want (Wish) Statement AB The toy should preferably be manufactured in different colors. The toy must be safe for the child to play with, by himself or with others. The toy should be made from recycled material. The toy should be highly aesthetic if possible (attractive). C. A problem statement answers the questions What, Why and How? Using the table below, match the statements to the right component of a problem statement. [3 marks]
