Design Brief

1. Introduction
   
   Materials handling technology, for transporting building material between locations and levels on a building site, in an integral part of modern construction environment.
   
   Design a model of a portable materials handling device to the general specifications outlined below.
   
   The machine should:
   
   1. Be capable of delivering materials to and from different levels;
   2. Be mobile to facilitate transportation between site locations;
   3. Be controlled by an ON/OFF switch;
   4. Include an electronic indicator to signal that the device is in operation.
   
   Presentation of the completed machine should ensure that:
   
   
   1. All main operating features are clearly visible without dismantling.
   2. The longest dimension of the model does not exceed 300mm.
   3. Electric power does not exceed 9 volts.
      
       
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 solution by examiner.
   
   Note: Computer-aided design (CAD) should be used where possible.
   
    
3. Design Realisation (110 marks)
   
   Using appropriate materials, make the machine 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 pans;
   2. Unnecessary recycling will result in lost marks. Re-cycling 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.
      
       
4. Project presentation
   
   Your completed project consisting of the device 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 device and folio.
