  3. A Mechanical Toy Design Learning Opportunities: To introduce pupils to basic mechanisms / mechanical movement – cams / eccentricity; To develop basic design and manufacturing skills; Design Appreciation: to understand that changes could be made to the design and to develop an awareness of the constraints when manufacturing. To develop an understanding of a range of manufacture processes; To introduce basic engineering concepts – fiction, Interference / clearance-fit, eccentricity, etc. Activity Description: Theory Mechanical Systems: : The pupils study mechanisms for approximately 3 x 35min periods; Manufacture: To manufacture a number of the models parts from set working drawings; Mechanisms

  4. A Mechanical Toy Design • Design Opportunities: • Show using concept sketches five alternative designs • for the frog’s body; • Explain using graphics the mechanical solution for making the • toy move up and down include notes / annotation; • c) Show using graphics how a cam may be fitted to make the head • move up and down (reciprocate motion); • d) Show examples of where an interference-fit and a clearance-fit • is used in this project; • e) Name two suitable materials for the body and wheels of this toy • design? • State a suitable protective finish for this project?

  7. A Mechanical Toy Design Learning Opportunities: To introduce pupils to basic mechanisms and mechanical movement - cams, & linkages; To develop basic manufacturing skills and techniques; To develop a range of design and manufacture skills; To understanding a basic product specification; To be able to interpret a working drawing. Activity Description: Theory: The pupils study mechanisms for approximately 3 x 35min periods Manufacture: To manufacture a number of the models parts from set working drawings. Design Appreciation: to discuss alternative modifications to the toy design / reverse engineering Mechanisms
