Hello, my name's Mrs. Taylor, and I'm really glad you can be with me to join me for this lesson today.

Let's begin.

Our lesson is in the unit Product Analysis, Encouraging Healthy Lifestyles, and the title of today's lesson: Why and how designers analyse products.

The outcome.

I can analyse a product to identify successful features and those which can be improved.

The keywords.

Context.

This is the situation within which something exists or happens.

Analysis.

Examining something in detail.

Function.

The purpose of the product.

And form.

A particular shape linked to aesthetics.

In this lesson, we have four learning cycles.

Investigate the context.

Why designers analyse products.

How designers analyse products.

And then, analyse a product.

We'll begin with investigate the context.

All design and technological practise takes place within contexts that inform outcomes.

A context is the situation within which something exists or happens.

It is the starting point for investigating, analysing, and then identifying a design opportunity.

They are sometimes called contextual challenges.

Which of the following statements are true? A, all design and technological practise takes place within contexts.

B, a context is what you will design.

C, a context is the situation within which something exists or happens.

D, everyone with the same context designs the same thing.

Pause the video and have a go.

Well done.

Let's check.

That's right.

A, all design and technological practise takes place within contexts.

And C, a context in the situation is a situation within which something exists or happened.

The context in this unit is encouraging healthy lifestyles.

We are going to investigate this context using a mind map.

There are different strategies for exploring a context.

One strategy is the four Ws.

These are who, what, where, and why.

Now we'll have a check.

We can use the four Ws to investigate a context.

What are the four Ws? Pause the video and have a go.

And let's have a look at the answers.

Who, where, what, and why.

Fantastic.

Beginning with the context in the centre, we branch out and consider each W in turn adding to the mind map.

So here we have our context for today, encouraging healthy lifestyles.

And we add who and we think of the different people that we might consider.

So here we have students, the elderly, and children.

We then add another W, what, and we consider sleep, diet, exercise, and hydration.

The where could be work, travelling, school, or home.

And the why, healthy eating, staying active, and reducing health problems. Task A, add more points to the branches of this mind map and then annotate to explain your thinking.

So for example, where we have encouraging a healthy lifestyle, what, and hydration, we have added drink six to eight glasses of water per day.

Pause the video and have a go.

Well done.

Let's have a look at some of the answers you may have.

So we've already got the four Ws and some words.

We're now adding more words and an explanation of some of those.

So for example, the elderly, loneliness can lead to mental health issues.

Sleep, sleep is essential for your physical and mental wellbeing.

Adults need between seven and nine hours sleep a night.

And the Eat Well Guide sets out the principles for a varied and balanced diet.

Well done.

We move on to learning cycle two, why designers analyse products.

Designers use the context mind map to plan research in more detail.

One strategy designers use is to analyse existing products.

This is called product analysis.

Product analysis is primary research as the researcher collects the data or information.

Let's have a check.

Why is product analysis primary research? A, it happens first.

B, the information is collected by the researcher.

C, the research is new; no one else has carried it out before.

Pause the video and have a go.

Let's look at the answers.

That's right.

The information is collected by the researcher and the research is new because no one else has carried it out before.

Analysis of existing products shows designers which features are successful and which could be improved.

Here we have two examples of a mobile phone.

What features do you think have been improved? Pause the video and have a think.

Brilliant.

You might have said that the antenna in the phone on the left is now built in to the phone on the right.

You may have also said that the phone on the left is larger than the phone on the right.

You could have also said that buttons and no screen are available on the phone on the left and that's an improvement in the phone on the right.

Well done.

Let's have a check.

Why do designers analyse existing products? To copy ideas, to identify successful features or to identify features which could be improved.

Pause the video.

Okay, let's look.

That's right.

B, identify successful features and C, identify features which could be improved.

Well done.

Let's move on.

Task B.

The context in this unit is encouraging healthy lifestyles.

We are going to focus on kitchen products we might use to prepare and cook fresh food.

Select an existing product that is suitable for analysis and justify your decision in relation to the context.

Why have you chosen that product? Which features are you going to focus on? Well done.

Let's have a look.

Alex describes why he chose a cheese grater.

I selected a cheese grater because they are used for different foods.

I am interested to know if they work well for all different healthy foods like carrots.

Lucas chose a vegetable peeler because vegetables are a key food group in a healthy lifestyle.

I want to see how safe it is for different users.

My little sister can use the one at home for long straight vegetables like parsnips but finds it difficult for round potatoes.

Izzy chose the weighing scales because portion control is an important part of a healthy lifestyle.

The weighing scales have several different parts.

I am interested how the bowl fits onto the scales and can also be easily removed when measuring different ingredients.

Well done.

We're now moving on to how designers analyse products.

When analysing products, designers can use subheadings and questions to frame their thoughts.

It is important to select the subheadings which are suitable for the context.

We will focus on kitchen products we use to prepare and cook fresh food within the context of encouraging healthy lifestyle.

The subheadings which can be used to frame product analysis include environment, manufacture, safety, function, cost, ergonomics, user, form, aesthetics, lifecycle, materials, and size.

We can also use questions to help with analysing.

So here are some subheadings and their questions.

The environment.

How will this product affect the earth? The cost.

How much does this product cost to produce, to buy, or to use? And aesthetics, which is linked to appearance.

How does colour, shape, and texture affect the style of the product? Let's have a check.

Aesthetics considers which of the following, colour, size, cost, or style? Pause the video.

Fantastic.

Let's check.

That's correct.

A, colour, and D, style.

Let's move on.

Here we have some more subheadings that we might use when analysing.

Manufacture.

How does the manufacturing process influence the design? Ergonomics.

How well does this product fit the user? How comfortable is it? Life cycle.

What is the product's environmental impact before, during, and after use? We've got another check.

Ergonomics considers which of the following, shape, weight, positioning, or colour? Pause the video.

Well done.

Let's check.

That's right.

Ergonomics considers shape, weight, and positioning.

For example, where the light switch might be positioned on the wall.

We have some more subheadings and questions which could be used when analysing.

Safety.

What features of the design ensure the product is safe to use? User.

Does this product meet the user's needs and wants? Materials.

How does the choice of material affect the function? We have another check.

Which of the following questions could you consider when analysing if a product is safe to use? A, does the style fit my client's needs? B, is the material or surface finish toxic? C, are there any electrical components? And D, are there small or loose parts? Pause the video and have a go.

Ready to check? That's right.

Is the material or surface finish toxic? Are there any electrical components? Are there any small or loose parts? Brilliant.

We have some further subheadings and questions which we could use.

Function.

What is the purpose of this product? Form.

What is the shape of this product? And size.

What is the size of this product? Here is task C.

Select a product to analyse within the context of encouraging healthy lifestyles.

For example, you might choose a cheese grater, a vegetable peeler, some weighing scales, or a tin opener.

You then, for the chosen product, select six suitable subheadings and then explain why you have selected each subheading.

Pause the video and have a go.

Brilliant work.

Let's have a look at some answers that you may have come up with.

This example chooses a tin opener and the suitable subheadings are material, form, ergonomics, function, user, and cost.

Aisha explains why she chose materials and function for two of the subheadings.

I chose materials because two different materials are used in the tin opener for different reasons.

I chose function because I think it has both a primary and a secondary function.

And now we move on to analyse a product.

To analyse the product, the subheadings and questions are explored further using bullet points to answer the question with justifications.

So here Aisha explains, I chose function and the question, what is the purpose of the product? The primary function is to open tins.

This is done through a small circular blade which is forced into the tin when you squeeze the handles together.

The secondary function is a bottle opener which is situated at the end of the product to open bottles.

Let's have a check.

What should you use when answering questions? A, mind maps, B, justifications, or C, sketches? Pause the video.

Okay, let's have a look.

That's right, B, justifications.

An important part of the analysis is the summary.

This will include the successful features identified in the analysis and those which could be improved.

Aisha says that the successful features she's identified are the materials are suitable for cleaning with water and detergent.

This is important as it may get messy when opening tins of food.

And the features which could be improved, she identified the round blade is exposed, which could be dangerous for the user, especially when cleaning.

Let's have a check.

What should a summary include? A, successful features, B, justifications, C, features to be improved, or D, new ideas? Pause the video.

Wonderful, let's check.

That's right, successful features, justifications, and features to be improved should all be included in your summary.

Here we have task D.

The first thing you need to do is analyse the product within the context of encouraging healthy lifestyles.

Include the subheadings and questions to frame the analysis.

And bullet points to answer the questions with justifications.

The second part is to consider which features are successful and those which could be improved.

Pause the video.

Well done.

Let's now consider some of the answers that you may have come up with.

Let's have a look.

Function.

The function of this product is to open tins.

There is one small circular blade which is forced into the tin when you squeeze the handles together.

This is then moved around the edge of the tin when you twist the handle and control the mechanism.

It has an additional feature, a bottle opener.

Materials.

Stainless steel for the moving and mechanical parts.

This is suitable for kitchen equipment because it does not corrode when it gets wet.

This also means it can be washed.

There is polymer for the handles.

This is softer and warmer to hold than the stainless steel and allows for colours to be added.

The successful features could include, it works well at opening tins and has an additional bottle opener feature.

The aesthetics are clean and professional looking.

Features which could be improved.

Stainless steel and polymers are not sustainable and combined are also more difficult to recycle.

It doesn't look fun or interesting, just functional.

If the user doesn't have much finger strength, it would be difficult to squeeze the handles with enough force to pierce the tin.

If the user has a small hand span, it might be difficult to hold both handles in one hand.

Well done.

Here we have the summary of today's lesson.

Design and technological practise takes place within contexts which inform outcomes.

A context can be investigated using a mind map.

Designers can use strategies to help them perform analysis.

Designers analyse products to identify successful features and those which can be improved.

Thank you for joining me today.

Well done.
