Product Evaluation: A Hairdryer Essay -- Papers

mathematical product Evaluation A Hairdryer Introduction. I am a 4th division student in St Patricks Grammar school Downpatrick studying technology and design for my GCSE. I must do two focused tasks, my first task is a product evaluation, for this task I will be evaluating a hairdryer construct by Vidal Sassoon. Justification. I picked this lash-up because It is a commonly used kin object. I have this appliance in my house so I can look at it whilst testing it against my specification. It is a unisex appliance used by all age groups. I am interest to find out how this appliance actually works. It fits the criteria which is It must have an subdivision 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 slight insulator which does non conduct electricity, heat and is also waterproof. It will non reshape with high temperatures. The electric chemical element which is housed well deep down the hairdryer does not come in contact with wet hair. An additional feature of this hairdryer is that it has an machinelike safety cut-off facility. If there is any danger to the user or if it heats up above a certain temperature the trip switch located in the electric meter box switches. There are square influence 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 machine-accessible to the rear of the extendle 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 suitable metal. This metal element/core, has to be able to be worked into convoluted shapes. So obviously it is going to be a light approximate metal and the beat conductor of electricity and heat. Through science, I be that copper is the best conductor of electricity, but the disadvantage is that it tends to be expensive. Aesthetics. The overall colour scheme is silver at the nozzle and maroon at the handle. The buttons and wiring are black. The plastic has a shiny high caliber finish, it gets this from the compression moulding and the properties of the plastic. The metallic material 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.
