Writing Instructions Jeffrey Donnell MRDC 3104 894-8568
Qualities of excellent instructions • The assembled device is shown first • Drawings use consistent orientation • Each step is numbered, with numbers consistently placed • Each drawing shows the complete device at the end of the assembly step • Assembly steps add only a few components, with each component fully drawn • Arrows are used to characterize alignment • Subassemblies are also fully drawn, with attention to orientation
Lego toys exemplify excellence in instructions This simple Star Wars toy contains about 30 parts. The instruction booklet contains 10 drawings, 7 numbered steps and two subassembly drawings that combine several steps each.
Orientation plan for drawing set is prominently shown in first drawing Emperor’s chair faces user Platform angled to user’s left Overview of assembled toy is shown first
The first subassemblydemonstrates alignment • The completed figures have identical orientation • Components are aligned and linked with arrows
Assembly steps(in slide 7) • Assembly steps maintain orientation of overview • Two components are added in each step • Each drawing represents the entire toy at the end of the step • Step numbers are consistently placed for each drawing
Final step integrates a subassembly • Subassembly drawing maintains orientation of overview • The overview drawing is recycled as step 7, the final step
Three steps are shown on one sheet Foot Seat Bar
A single assembly step:three vital pieces of information Orientation Completed Step Alignment
Overview drawing provides orientation information Angled to user’s left Figure number is prominent
Overview information provides landmarks Components are assigned names and reference letters for marking Orientation and figure number are preserved
Assembly steps explained • One step is captured in 4 drawings • 24 pieces are used in this step • Orientation and numbering are carefully preserved • Finished step resembles overview drawing
What teams must determine • How many drawings are required for this construction task? • What orientation will these drawings take? • How many components will be added in each step? • Where will the step numbers and text be placed?
What you should do--I • Design your system • Draw your system • Test your system (as possible)
What you should do--II • Draw and label the assembled design • Draw the components • Characterize fabrication of each main component • Prepare instructions for assembly of final product
Drawings you want • 1 overview of the design • Sketches of major components • Illustrations for for fabricating components
Writing instructions--IThe introduction • Introduction paragraph • Present and describe drawing of assembled system • Describe overview and components • Inventory • List components, with sketches
Writing instructions--IIMaking the components • Component assembly • How to orient and mark the newspaper sheet • Where to fold, bend, etc. • Label the finished component for later assembly
Writing instructions--IIIFinal assembly • Assemble components • Take component A and component B • Insert flap A-1 into slot B-3 • Repeat until done
Concerns about drawings • Assembled system should be displayed and described first • Drawings should provide orientation markers • Sequences of drawings should display consistent orientation • Drawings should show numbers to indicate sequence
How landmarks disappear Reorientation disrupts context
Reports on this project • Introduction • Design overview--a • Draw, present and describe your design • Discussion--a • Draw and describe alternatives, evaluate construction results • Design overview--b • Draw, present and describe the frame you constructed • Discussion--b • Illustrate and discuss construction results, evaluate design • Closure
