AIMS and OBJECTIVESAIMS and OBJECTIVESTO BUILD A SIMPLE PowerPoint PRESENTATION.
To encourage its use in the classroom.
THE CONTENT OF SLIDES TO OUTLINE A MANAGEMENT APPROACH TO DESIGNING AND REPORT WRITING.
SLIDES MAY BE USED AS BOTH A LEARNING RESOURCE FOR STUDENTS (a self learning tool) AND A TEACHING AID FOR TEACHERS.
Presented by P.Byrne
FOLDERS, REPORTS and FOLIO WRITING FORTECHNOLOGICAL SUBJECTS:
• Front cover to include subject, level and year.
• Contents page
• Design loop.
• Analysis of Brief.
• Investigation of solutions
• Design Solution.
• Criteria for selection of solution.
• Production and Drawings / Plans.
• Testing and Evaluation
• Neat Presentation.
Analysing of Brief:
Tease out and expand on given Brief, specify requested requirements but also include new requirements particular to the individual item under design.
What has it to do
What has it to look like.
Other requirements.
Individuals own creative input.
Break down Brief.
Support the brief.

Testing and Evaluation
Common Errors:
(Folders)
•Students include unnecessary details such as the theoretical descriptions of common workshop tools.
•Downloaded information from Internet without any attempt at analysis.
•No need for long descriptions of processes used.
•No worthwhile analysis of brief.
•No investigations of possible solutions.
•No planning. No reasons given for selection.
Common Errors. Continued.
•Final design appears without any evidence of any process of thought.
•No testing with honest results.
•No evaluation.
•Poor overall presentation of booklet.
•Drawings to a poor standard.
•No working drawings with dimensions.
WHY A DESIGN FOLDER
# COMMUNICATION AND DEVELOPMENT OF IDEAS.
# Ideas must be researched, developed, tested, modeled, modified and recorded before the right solution is found.
# A large percentage of final mark is allocated to the folder
# A management structure, record of activities.
MAKING THE FOLDER.
• PORTRAIT OR LANDSCAPE
• METHOD OF BINDING
• SKETCHES• DTP or Word
processing.• CAD.• Page Titles.
•Try to think of as many ideas as you can
•Do not just develop your first idea.
•Try to think of at least three ideas
•Outline three advantages and three disadvantages for each.
Record all ideas (write + sketch) and develop them further by sketches.
PROJECT DEVELOPMENTPROJECT DEVELOPMENT
Technological Factors.
• Appropriate materials• Suitable construction.• Durability: to
withstand use.• Cost.• Form and function.• Function no longer
rules over form.
ARTISTIC FACTORS.
Taste is influenced:
•upbringing, personal environment.
•Exposure to various media,
advertising, TV, magazines.
•Fashion.
APPEARANCEAPPEARANCE
Good proportions.
Strength / weight ratio.
Colour.
Feel / Touch.
Finish.
Quality of Material
Shape / Sturdiness.
INVESTIGATION:
Make a list of all things you feel the product should have.
BRAINSTORM
WHAT MUST THE PRODUCT DO OR HAVE?
RESEARCH TYPES ALREADY AVAILABLE
Establish their positive factors.
Find out everything you can about each factor.
ANALYSIS• What will it do?• Where will it be used?• Who will use it?• When will it be used?• Why will it be used?• How will it affect
people using it?• What must it
demonstrate?Scatter or bubble chartScatter or bubble chart.
DESIGN SPECIFICATION:
LIST OF WHAT THE FINAL PRODUCT MUST DO OR HAVE.
The list or spec. is derived from:
•The Brief. * Weight / strength ratios.
•Investigations. * Constraints.( Limits of size)
•Research * Environmental factors
•Dimensional limitations. *Visibility.
•Aesthetics. *Maintenance needs. ANALYSISANALYSIS
THE SPECIFICATION:
LIST OF FACTORS: WHAT THE PRODUCT MUST DO OR HAVE.
ANALYSIS OF THESE FACTORS:
RESEARCH HOW BEST YOU CAN CREATE THESE FACTORS FROM MEANS ALREADY AVAILABLE.
FINAL SPECIFICATION:
COMMON TO ALL DESIGNS
SPECIFIC TO YOUR INDIVIDUAL DESIGN.
COMMON TO ALL SPECS:• Safety.• Finish.• Quality.• Appearance.• Maintenance.• Ergonomics.• Service Life.• Cost.• Constraints requested.
Technological Subjects.
•Engineering.
•Construction Studies
•Materials Technology (Wood)
•Technology
GATHERING INFORMATION• Experimentation: weighing,
lifting,measuring data. (identify aims and collect results)
• Surveys: people expectations, popularity of products.
• Reading.
• Internet: Make sure analysis is carried out.
• Contact manufacturing companies.
FINDING IDEAS:
• CONCEPT SKETCHES.
• IDEA SHEETS (Explore possibilities and develop ideas)
• PRODUCTS ALREADY EXISTING.
COMMUNICATING IDEAS
• Written information.• Diagrams• Sketches• Drawings.• Computer graphics• Desk Top Publishing.• Models and Prototypes.• Digital images.
MODELS or PROTOTYPES
• Cardboard, cereal boxes, matches, straws.
• Styrofoam.
• Modelling woods: Balsa or Jelutong are good for prototype building.
• No material to be cut without appropriate approved model. (Teacher Intervention).
DEVELOPMENT OF IDEAS.
CARDBOARD MOCK UPS.
REFLECT AND REVIEW.
MECHANICAL MOVEMENT.
ELECTRONIC CIRCUIT DESIGNS
SKETCH AND REVIEW.
DECIDE, RECHECK BRIEF AND SPECIFICATION
Consult with Teacher.
DRAWINGS
• FROM FINAL PROTOTYPE:
• CONSULTATION WITH TEACHER.
• WORKING DRAWINGS.
• CUTTING LIST.
• ALTERATIONS.• MANUFACTURE• ALTERATIONS• ADJUST WORKING
DRAWINGS• MODIFICATIONS

REASONS FOR SELECTIONREASONS FOR SELECTIONOFOF
DESIGNDESIGNSOLUTION:SOLUTION:
CRITERIA
Oooh, it could work better if !
Check if change is really necessary?
Is it a sensible change?
Is there enough time to change?
Consult Teacher.
FINAL EVALUATION• How it compares to
original intention;
• Does it solve the original problem;
• What it looks like;
• How well it operates;
• Manufacturing cost;
• How it could be improved.
• Safety!
REMEMBERREMEMBER
EVEN THE BEST PRODUCT CAN BE IMPROVED.
PROJECT HAZING DUE TO EXCESSIVE USE OF ADHESIVES
POOR STRENGTH / WEIGHT RATIOS
POOR ATTENTION TO SAFETY
NO ACCESS FOR MAINTENANCE / REPLACEMENT.
UNNECESSARY RECYLING.
DIMENSIONAL LIMIT AND CONSTRAINTS NOT OBSERVED.
UNTIDY CIRCUITS / POOR CONNECTIONS.
PROJECTPOOR STABILITY. POOR BALANCE.
POOR PROPORTIONS (Length to width)
POOR FINISH ON INDIVIDUAL PARTS (Quality of Work)
OVERALL APPEARANCE POOR.
Low level of Skills applied.
Material used too heavy, too flexible, Opaque.
Body too heavy for selected drive.
Light fixings where more robust were needed.
Heavy screws holding light material.
CONCLUSIONSCONCLUSIONS
A TIME plan is necessary.
Sketches, scribbles, scatter charts lead to solutions.
Discuss with your TEACHER (regularly).
Simplicity is often most effective.
No prototype No make.
Test any circuits on breadboards firstly.
Neatness and care pay.
