Raymond Moffatt welb Technology & Design A design opportunity! Unit 4: A suggested approach.
Design Brief 1: Safe Cycling Context: In recent years Safe Cycling has become an important issue. In an effort to reduce annual death tolls and injury rates on roads you are asked to undertake research and design into the use of “bicycle mirrors” Design Brief / Opportunity: Design a bicycle mirror that will help make the cyclist more aware of rear view traffic and assist in safe cycling for all Develop your idea, considering the following factors: Function, materials, compactness, assembly, attachment, ease of use, aesthetics, manufacturing, safety. Unit 4: Assignment Safe Cycling Hyperlink – research.
A Design Opportunity: A? B? A Bicycle Mirror: a)How will part ‘A’ be linked to the handlebars? b)What will be the form/shape of part ‘B’ c)What materials would be suitable for part ‘B’ ? d) Could part ‘B’ be injection moulding and made from a hard plastic? C?
A: Mirror housing?? B: How will the housing be secured to the round steel rod? C: How will the steel rod be attached to the handlebars? A B C Bicycle Mirror: 8mm diameter chrome steel rod
Part ‘C’ ? What will you need to find out? Make reference to your reference materials as to:- How this has influenced you in relation to the design, shape, form, function, materials, suitability? Make (3) concept sketches developing one idea chosen from your research:
a)What do you need to find out about the handlebars? b)Could the mirror be attached to any other part of the bicycle? Analysis:
a) Discuss and develop this idea to show how it may be modified to hold the 8mm steel bar / rod. b) Why might you need to use card for modelling? C 8mm diameter chrome steel rod
a)Discuss and develop the clips to show how one may be modified to hold the 8mm steel bar / rod; b) Why do you think this item has been selected? C 8mm diameter chrome steel rod
a)Discuss and develop the above clamps to show how they may be modified to hold the 8mm steel rod. b)What material do you think these clamps are made from? c)What manufacturing process was used to make these clamp? C 8mm diameter chrome steel rod
a)Show using sketches how the round rod fits to part ‘A’? a)Develop the clip to make it more refined / aesthetically pleasing. b)Using sketches explain how this mirror could be adjusted? ‘A’ Clip
a)Discuss the above clamps and develop it to show a practical use to solve the attachment of the mirror. b)Explain the term carbon fibre and why do you think this material is used in bicycles?
a)Consider the sketches above in relation to housing the mirror for part ‘A’; b)Develop this idea to show how the mirror could be secured? c)What material/s would be suitable for manufacture?
