In this unit we are going to look at importance of design specification

In this unit we have combined the expertise on three individuals to show you how they use design specifications.

I have taught pupils how to design for a number of years, testing a number of strategies

I have my own design company and I will show you how commercial designers work.

Having worked as a graphic designers, I have combined some of the methods we used there with ones we use in the department.

Design idea 2

How many of your ideas were similar to these ?


In this unit we are going to look at importance of design specification

What the designer thought of the designs ideas.

Ok an interesting range of ideas, but your teacher left out some important details that you needed to know when designing – any thoughts?

Was the task clear?

Children can range in age from 3 to 12. You had to guess at which age range to aim the product at.

Guessing can lead to mistakes.


In this unit we are going to look at importance of design specification

As you have seen, a general brief such as “Design a desk for a children’s bedroom” is sovague, that it is difficult to know exactly what is needed and how to respond correctly to the customer’s requirements.

To overcome this problem, designers use a design specification to describe in detail what the finished product will have to do in order to be successful.

Before you go back to designing the desk for the 5 year old, yes I remembered to tell you the age this time. It might help you to try out the these tasks.

For each of the products select which statement you think is : an important aspect of that product

or not important. Have a go.

So what information do we need to design this desk?

The child’s age? maybe if it’s a boy or a girl? – what do they like? – what it needs to look like? – age, gender,appearance.

What they are going to use the desk for? painting, writing, storing books – function. What size will the child be? – measurements.

How safe will it be for them to use? sharp edges - safety


In this unit we are going to look at importance of design specification

  • Specification:-

  • Appearance

  • To attract the attention of a 5 year old child.

  • Effective use of colours.

  • Based on characters suitable for a 5 year old child.

From the previous questions we asked ourselves, we drew up some guidelines that should make sure that the product, will be successfully designed.

  • 2. Function.

  • Practical – writing, colouring, painting.

  • Storage for colouring equipment – crayon, colouring pencils, colouring books

  • 3. Sustainability

  • Source materials that have a low environmental impact..

  • Well designed, long lasting so that it can handed on.

  • 4. Safety

  • Safe to use, no sharp corners.

  • Non toxic finish.

  • 5. Measurements.

  • Size suitable for a 5 year old child.

Weight

We have seen how important it is to make a specification clear. Containing enough information so the designer knows exactly what the products needs to, for example, do (function) or look like (appearance).

There are a number of specification details that need further consideration – any thoughts ?

Lets look at these in further detail in the next unit.
