  1. Craft & Design Occasional TablE Boclair Academy Teacher Your Name & Class.

  2. Page Heading Design your own page layout, to be reproduced on every page of your folio – this is only a suggestion. Use bubble lettering, stencil or computer print out lettering. Border should be drawn first in pencil, then rendered with coloured pencil and the outline finished with black fineliner pen. A sketch of your developed idea (solution) to be drawn on every page - alternatively a logo or other design could be used to enhance the page layout.

  3. Design Problem These are some of the items I have lying around my in my room making it look very untidy. I need something other than the window sill and shelf to put things on! Design Brief Design an occasional table for use in my kitchen, living room or bedroom.

  4. Design Specification • Size – Not to exceed 800 long x 500 wide x 475 high. • Cost – Cost of materials to be aprox. £5.00. • Manufacture – Must be able to be made in a school workshop, using the tools and equipment found there. • Time – Must be made in a maximum of between 20 and 24hrs. • Maintenance – Must be of a suitable design as to require only occasional maintenance. • Function – Has to be able to support items such as table lamps, crockery, tea pots, cups and saucers,ornaments etc. • Safety – A smooth finish with no sharp edges is required for domestic use. • Ergonomics - Must be ergonomically designed with consideration given to ease of use by humans. • Finish – A suitable durable finish appropriate for the situation and environment into which the article is to be placed.

  5. Design Specification • Appearance – Must fit in with the style of décor and room into which the article is to be placed. • Environment – Consideration of the type of environment in which the article is to be placed or used. Eg. Hot tea pots being placed on the surface, ease of cleaning, stain resistance. • Shape & Form – Consideration to the most suitable shape to be used in the room. Eg. Square, circular, oval, rectangular. • Materials – Main material will be red pine with birch ply used for table tops if necessary.

  7. Morphological Analysis

  8. Design Ideas • Sketch Quickly 8 to 10 design ideas. Your initial ideas should be of outline shapes for table tops, and 2D sketches for the legs & rails. • Your sketches should be a way of thinking on paper and use notes beside your sketches to explain your ideas. • This stage should not take long- about 1hour. If you have a deadline you must stick to it – Just as professional designers have to!

  13. Rail Design

  14. Evaluating Design Ideas • For each of your design ideas it is important that you evaluate each of them in turn. Write a short evaluation for each of your design ideas – you may wish to consider each of these points when evaluating. • Does it meet the design brief ? • Does it meet the design specification ? • If it doesn’t, can it be modified to meet brief/spec ? • Is it possible to make the solution with the skills/equip/materials that are available ? • Will it be within the cost limits • In your design work it is essential that you write down your reasons for making choices and decisions. Refer to pg. 7 in Revision notes.

  15. Research Materials To consider the most suitable materials, we must first consider what the materials will have to do. Make a tick box table of the material requirements. Refer to page 8 of your revision notes. • Draw up another table of suitable materials and tick off which may be most suited to your requirements.Copy these pages into your folio: • WWood Pages 24 & 25 of Rev. Notes. • MMetal Page 27 • PPlastic Page 29

  16. Research • Consider these points : • Size & Shape • How the solution will suit the people who use it! • Look at ergonomics/anthropometrics pages 18 19 and 20 of the revision notes. See also your handout on ‘Ergonomics & Anthropometrics. • Copy the definitions into your folio. • Copy anthropometric figure page 4. • Copy sketches on range of movement page 6. • Copy sketches on reach page 9. • Appearance & ‘Aesthetics’ • A product which works well but is not pleasing to look at will not sell well. The visual qualities which give an object a pleasing appearance are called ‘Aesthetics’. Read pages 15 to 18 in revision notes. • Copy page 33 in CDT Design Realisation of the Parthenon and Golden Section. Read & copy page 26 & 27 CDT Design Realisation

  17. Research • The 5th – 95th Percentile • The designer tries to design for as many people as possible but there are a few people at either end of the distribution curve (graph) who may not be catered for. The aim is to design for at least 90% of the total number of people.This means that 5% at each end of the scale are not taken into consideration. These limits are known as the 5th – 95th percentile. • Copy this definition into your folio. Page 5 Rev. Notes • Sketch the graph of the distribution curve. • Copy example A and B into your folio. Distribution Curve Smallest People ( 5%) Tallest People (5%) 90% of ‘Average’ People

  18. Research Planning Sketch 2 to 3 pages of of tools and equipment that will be required to manufacture your table. Trace the tools from your revision notes if required. Include a description of the uses of the tools.

  19. Developing Design Ideas You can develop and refine your design ideas to produce your chosen design solution. It is possible at this stage to test your ideas by making a 3 dimensional scale model from card. Your design sketching should show a progression of thought, moving and adapting your ideas while adding notes (annotating) to explain your improvements and modifications. Use arrows, stars, exclamation marks and callouts to indicate progression of thought and good ideas! I like this Idea. !

  20. Development of Design Ideas I have chosen this idea to develop into my solution. Develop the following aspects of this idea : Top, Legs, Rails. Moulded edge shaped onto frame using plunge router. Too expensive for solid pine top. Solid Top Rebate made in frame to allow glass to fit. Frame top with mitred corners. Glass Top Glass Wooden Frame

  21. Development of Design Ideas 2 I have chosen this idea to develop into my solution. Develop the following aspects of this idea : Top, Legs, Rails. This is the style of leg I have chosen. It will mean I have to modify my design. I have had to remove the bottom rail from my design to accommodate the shape of the legs but the result is more aesthetic.

  22. Developed Idea Vanishing Point 500 450 800 Draw a pictorial view of your solution, in 1 or 2 point perspective. Show the main dimensions of your table and annotate (add notes) your sketch to indicate design features & finishes.

  23. Working Drawing Produce a working drawing to show the elevation, end elevation and plan in the positions shown. These views should be drawn with instruments on a drawing board and be to a scale of 1:10 or 1:5 Plan End Elevation Elevation

  24. Cutting List

  25. Presentation Drawing

  26. Manufacturing Procedure • Make a list of bullet points or a flow chart that describes step by step, how to manufacture your table from the start. For each step, this list of instructions should include: • A short description of the tasks being undertaken. • A sketch of the joint being made / process carried out or tools and equipment used at that stage. • Approx. 10 – 12 stages in total should be sufficient. • For Example: • Mark out legs using a try square,steel rule and pencil.(draw a sketch of this – trace from your Rev. Notes if necessary). • Using a mortise gauge mark on the gauge lines for the mortises.(sketch this procedure). • Etc.

  27. Design Evaluation Design Problem……..What was it ? State it below. ………………………………………………………………………………… Does your design solution work? Is it aesthetically pleasing? Does it solve the original design problem? Is it durable (strong enough to withstand breakage in normal use)? Are there any weak points in its construction? Do you think the materials used were the most suitable? Could a better finish have been applied? Will this Item require maintenance? (repainting, varnishing etc.) Did you require to alter your original design during manufacture? Is it worth the cost of the materials? Is your item of similar quality to that which could be purchased from a shop? Yes No

  28. Design Evaluation 2 Any comments on your answers to the questions on the previous page? ………………………………………………………………………………………………. ………………………………………………………………………………………………. In making the item did you find it: (underline your choice) What were the problems you encountered when making the item? ………………………………………………………………………………………………. ………………………………………………………………………………………………. If you were to make this item again, what changes (if any) would you make to improve it? Add sketches to explain the changes. ………………………………………………………………………………………………. ………………………………………………………………………………………………. ………………………………………………………………………………………………. EASY REASONABLE DIFFICULT VERY DIFFICULT
