LC Technology OL Sample Design Folder
Assessment Project 50% Exam Paper 50% Design Folder: 40% Artefact: 60%
Sample Design Folder NCCA advice document to DES • Analysis, research and investigation • Overall management of project • Design ideas & selection of optimum solution • Sketches & drawings for manufacture • Environmental impact • Materials and production planning • Product realisation • Evaluation and critical reflection • Presentation and ICT
Analysis, Research and Investigation • Choose an area for research. • Research existing solutions. • Statement of candidate’s brief and specifications.
Analysis, Research and Investigation • I will research the following topics: • Personal Alarms • Burglar Alarms
Analysis, Research and Investigation Research existing solutions
Personal Safety Analysis, Research and Investigation Elderly Children Handicapped Single People
Analysis, Research and Investigation Elderly Hearing Disability Handicapped Visually Impaired Wheelchair Bound
Analysis, Research and Investigation • Associated Problems for Hearing Impaired: • awareness of caller - door bell / knocking! • telephone ringing • television / radio • cooker alarm • smoke alarm • intruder • dog barking All sound based
Analysis, Research and Investigation Alarm integrated into TV Remote Control
Analysis, Research and Investigation My Design Brief Design and manufacture a device which will signal to a hearing impaired person that someone is at the door. An output light will indicate when someone is at the door. The device will also include an alarm to indicate that an intruder has entered the house.
Analysis, Research and Investigation My Specifications • The device should be operated by a normal door-bell push button • When the button is pressed the LED will flash until the device is reset • It should be easy to change the battery • The product / device should also hold a TV remote control • I should be able to make the project in the Technology room • The electronic parts should be visible and accessible to the examiner • The product should be strong and withstand sudden shocks • The product should be environmentally friendly
Overall Management of the Project • Analysis of available resources • Time and budget constraints • Proposed timeframe/Gantt chart etc.
Overall Management of the Project Gantt Chart
Design Ideas & Selection of Optimum Solution • Three design ideas • Annotated sketches • Select one of the three ideas • Justify selection
Design Ideas & Selection of Optimum Solution Design Idea 1
Design Ideas & Selection of Optimum Solution Design Idea 2
Design Ideas & Selection of Optimum Solution Design Idea 3
Design Ideas & Selection of Optimum Solution Optimum Solution I have decided to select idea 1 as the design I will make. I will make the last version where there is a housing to contain the circuit as shown below in the sketch.
Design Ideas & Selection of Optimum Solution • I chose this idea because: • It does not have too many parts • All the parts are quite big so they will be easy to make • Acrylic is easy to shape and bend • A light will flash if an intruder enters the house • Another light will flash to show someone is at the door • It contains an electronic system • It will hold a remote control
Design Ideas & Selection of Optimum Solution Circuits • Outline how circuit works • Pros • Cons Circuit 1 Circuit 2 Circuit 3
Design Ideas & Selection of Optimum Solution • Optimum Solution • My circuit design will use a combination of circuit 2 and circuit 3.
Design Ideas & Selection of Optimum Solution • I chose this circuit because: • It will show when someone is at the door & when the door is open. • All the components are in the technology room. • I can use the CNC router to make the PCB board so soldering this circuit will be easier than using strip-board. • I have used push to make and push to break switches before so I am familiar with how they operate.

Sketches & Drawings for Manufacture Drawing Instruments
Environmental Impact • Impact of materials and production processes • Product use • Suitability for re-cycling.
Materials & Production Planning Work Breakdown Structure Diagram
Production Realisation • Sequence of manufacture • Photographic evidence
P.C.B. Layout Production Realisation • Sequence of manufacture • Photographic evidence
Evaluation & Critical Reflection • Testing of final artefact. • Evaluation against brief and specifications. • Comparison of planned schedules and actual schedules. • Suggested modifications with justification.
