Design Brief

1. Introduction
   
   Karting has progressively evolved as a motor sport since the first Kart was manufactured in the USA in 1958. Karting is considered the first step in any serious motor racer’s career and many Formula One drivers grew up racing Karts.
   Recognising that motor sports can be used as an agent for change, modern technological advancements have produced an Electric Kart capable of speeds of 100 km per hour. Continuous development of the Kart has involved experimentation with components and motor vehicle technology on racetracks, to inform the creation of a more eco-friendly automobile in general, with safety considerations being paramount in the design process.
   
   Design a model Electric Kart to the general specifications outlined below.
   The Kart should be your own unique design and should:
   
   (a) Have a rear wheel propulsion unit;
   (b) Incorporate an all-round shock absorbing protection system;
   (c) Include a steering mechanism;
   (d) Have two aerodynamic features, one of which should be adjustable.
   
   Presentation of the completed project should ensure that:
   
   (a) All main operating features are clearly visible without dismantling;
   (b) The longest dimension does not exceed 350 mm;
   (c) Electric power does not exceed 9 volts.
   
   Special Note: Modified toys are not acceptable.
   
   
2. Design Process (40 marks)
   
   A design folio must be compiled which will detail your :
   
   
   1. Analysis of the given brief and investigation of possible solutions;
   
   
   2. Criteria for selection of your own individual solution and production drawings/plans;
   
   
   3. Testing and evaluation of your design solution;
   
   
   4. Special instructions, if required, regarding the testing of the solution by the examiner.
   
   
   Note: Marks are awarded as shown in Marking Scheme (below).
   Computer-aided design (CAD) should be used where possible.
    
3. Design Realisation (110 marks)
   
   Using appropriate materials, make the model according to your own individual design plans. Computer numerical control (CNC) technology should be used, where possible, to support manufacture. You are required to manufacture and assemble all the parts, subject to the following guidelines :
   
   
   1. Standard components may be used to support the assembly and interconnection of various parts;
   
   
   2. Unnecessary recycling will result in lost marks. Recycling will be acceptable only in cases where a complex part cannot readily be made in the school;
   
   
   3. Bought-in electronic solutions will result in lost marks;
   
   
   4. Adhesives, if used, should be applied sparingly.
   
   
   Marks are awarded as shown in Marking Scheme (below).
   
    
4. Project Presentation
   
   Your completed project consisting of the model and design folio, both clearly identified with your examination number, must be available to the visiting examiner.
   
   Marks are awarded for quality of presentation and finished appearance of both the model and folio.
