Task Analysis

Task Analysis

1. Aesthetics

   • shape
     • aesthetically appealing
   • surface colour and surface finish
     • matte
     • gloss/ high shine
   • gives the ultimate impression of luxury
   • can the design be easily adapted for new models?
   • Lighting and other electronic components

2. Cost

   • cost depends on target market
     • if family target market, lower RRP
     • if sports car, higher RRP
   • cost of manufacture will be high
     • due to expensive mechanics
     • complex design process

3. Consumer

4. Target market

5. Environment

   • fuel consumption of vehicles
     • improved efficiency through aerodynamic design
     • type of fuel used (eg. hydrogen power, petrol, electricity)
     • increase miles per gallon using engine type
   • Are the materials used sustainable?
     • sources of materials
     • do they come from finite resources?
   • Product lifecycle
     • Recyclable parts
     • must waste minimum materials
       • reduced electricity consumption in manufacture
       • reduced use of finite resources = increased sustainability

6. Manufacture

   • manufacturing processes
     • industrial proceses
       • milling
       • vacuum forming or injection moulding polymers
     • metal working
   • factory location
     • availability of workforce
       • skills required of workforce
     • multiple different locations manufacturing different parts
     • transportation
       • import of raw materials and bought in components
       • export of finished products
       • accessibility
   • manufacture of the prototype
     • using school facilities and materials
       • condensed foam shaped using files and sanding
       • laser cutting
       • woods, condensed foam, vinyl, polymers
     • time
       • good time keeping required
       • effective project management
   • timespan for manufacture
     • how long does it take to build?

7. Health and Safety

8. Size

   • height and width restrictions
     • 7 feet wide width restricted
   • minimum clearance height under the vehicle
   • cars must be large enough to carry at least 1 passenger and the driver
     • plus suitable amounts of storage
     • normally 2, 4,5 or 7 seats

9. Function

   • must function as a car
     • transportation
       • number of passengers
         • removable seats?
     • storage capacity - boot?
     • number of doors
   • suitable for families?

10. Materials

    • polymers
      • for inerior parts of the car
    • smart and modern materials
      • heat sensitive eg thermochromic inks
      • phosphorescent inks
    • composite materials
      • carbon fibre
      • improved properties
        • strength and resistance
      • fibreglass
      • are these too expensive?

11. Cultural Issues

12. Form/ Shape

    • aesthetic quality
      • the shape must appeal to the consumer's desire for aesthetic beauty
    • Aerodynamics
      • reduce drag forces
        • by increasing laminar airflow around the chasis
        • reducing turbulence at the boundary layer around the vehicle
      • The effect of a vehicle's shape on the airflow around it

13. Durability

    • how long will the car last?
      • safety in case of an accident must be considered
        • crumple zones or roll bars
    • material choices
      • use of composite materials such as carbon fibre
        • expense of these materials
      • metals and metal alloys
        • maximise material strengths
    • no built in obselence
