Balancing Toy Buzzer Cover

A few ideas for a circuit box for a novelty door buzzer are shown above.

A novelty shop owner has commissioned a series of door buzzers with a balancing toy theme.

The balancing toy "switch" is complete but a circuit and circuit box are required to complete the product.

Design Brief

Design and make a circuit box for a circuit that consists of a battery holder, a buzzer and connecting wires.

Specifications

The circuit box must consist of a platform that supports the circuit components and a cover that hides the platform and components.
The circuit box design must allow the platform and cover to be fixed to a wall.
The sound of the buzzer must be heard through the circuit box.
The cover must be easily removable for replacement of batteries.
The circuit and circuit box must be safe to use.
The cover must have an interesting design.
The product must represent a thing of beauty and quality.

Use the information above to prepare a design folder and a prototype of the circuit and circuit box for the balancing toy buzzer. Use the design process animation to guide you through the stages of designing, planning and making your prototype.

Circuit Box for a Novelty Door Buzzer

Design Folder

Design brief and specification

You should have a copy of the design brief and specification in your folder.
Copy the specification and add your own specifications, e.g. state whether any special materials should be used or if you have any special requirements for the circuit box.

Research

If you need to research anything, e.g. how materials could be shaped, joined and finished etc. then all your research material should be in this section.

Designs

Use notes and sketches to record your ideas.
Develop your best idea.
Make a Parts Drawing of your final design, i.e. an accurate drawing, either full size or half size and add measurements for each part.
Describe how the parts should be "finished".

Planning for making

You should write a description of how each part of your design will be made, listing all the materials you will need and the tools that you will to use.
You should prepare a Gantt Chart showing how long you have to spend on researching, designing, planning and making.
You should prepare a cutting list of materials for your teacher.

Safety

Prepare a risk assessment of all the activities that you will be carrying out during researching, designing, planning and making the circuit and circuit box for the balancing toy buzzer. State the precautions you will take to ensure your safety and the safety of others.

Evaluation

Evaluate you final product by testing it to see how well it works and how good it looks.
State whether the product could be improved by:
- improving the design
- improving the materials used to make the product
- improving the measuring and marking out
- improving the cutting, shaping, moulding or casting
- improving the finish
- improve the method of joining the parts.

The Product

Make the circuit board and cover that fulfils the given design brief and specification.

This DMA may be presented on an interactive white board, used on a computer or printed on paper.

Before printing, the animation should be played until the picture
that you want to see on the print-out is on the computer screen.
