Product Evaluation: A Hairdryer Essay -- Papers

Product Evaluation A Hairdryer Introduction. I am a 4th year student in St Patricks Grammar school Downpatrick studying technology and public figure for my GCSE. I must do two foc utilize tasks, my first task is a product evaluation, for this task I will be evaluating a hairdryer make by Vidal Sassoon. Justification. I picked this appliance because It is a commonly used household object. I have this appliance in my house so I mess look at it whilst testing it against my specification. It is a unisex appliance used by all age groups. I am interested to find proscribed how this appliance actually works. It fits the criteria which is It must have an agent of control. It must have a power source. It must be a technological product. Safety. Plastic is used to make the casing of the hairdryer. Plastic is an excellent insulator which does not conduct electricity, heat and is also waterproof. It will not reshape with high temperatures. The electric element which is housed well inside the hairdryer does not come in contact with wet hair. An additional feature of this hairdryer is that it has an automatic safety cut-off facility. If there is any danger to the substance abuser or if it heats up above a certain temperature the trip switch located in the electric meter box switches. There are straightforwardly shaped grids at both ends of the appliance. These grids prevent hair from the user getting sucked inside the appliance. The grids also prevent dust from getting into the appliance and onto the element. The cable committed to the rear of the handle is well insulated. It is also quite flexible, which help... ...ed into shape. The heating element has to conduct electricity and heat, so it will be made of a desirable metal. This metal element/core, has to be able to be worked into complex shapes. So obviously it is going to be a light gauge metal and the cram conductor of electricity and heat. Through science, I know that copper is the best conductor of electricity, but the disadvantage is that it tends to be expensive. Aesthetics. The overall colour scheme is ash grey at the nozzle and maroon at the handle. The buttons and wiring are black. The plastic has a shiny high quality finish, it gets this from the compression moulding and the properties of the plastic. The metallic actual on the nozzle also has a high quality finish. The shape of the hairdryer is like a hand gun. All the edges on the hairdryer are curved.
