Lesson video

Hello there.

My name's Mrs. Taylor, and I'm really pleased you could join me here for our lesson today.

Our lesson is "Parts lists: textiles," and this is part of the "Iterative design: Nature" unit.

The outcome, I can prepare a parts list for my design.

We have three key words.

Parts list, components required to assemble a product.

Component means a single part of a larger product, and quantity is the amount or number of something.

This lesson has two parts.

The first is a parts list and the second is creating a parts list.

Let's begin.

A parts list, also called a bill of materials, is a structured document detailing the individual components required to assemble a product.

It supports accuracy, efficiency, and consistency in manufacture.

A well-structured parts list minimises errors, speeds up production, and ensures cost efficiency.

Let's have a check.

When manufacturing, a parts list supports A, accuracy, B, creativity, C, iterations, or D, efficiency? Pause the video and have a go.

Wonderful.

Let's check.

That's right, it's both A and D, accuracy and efficiency.

Well done.

A parts list supports the thinking needed in preparation of the manufacturer for all components of a design, not just the ones that are bought in.

They help identify the materials needed and the amount of those materials, which is referred to as the quantity.

in the creation of a parts list, mistakes that may have been made in previous design steps can be highlighted.

A parts list can be presented in a table.

This helps to keep it organised, helps to ensure accuracy, and supports clear understanding when reading.

Key elements of the table can be a part number.

This is where individual parts of the product are identified.

A part name and description, for example, the side, the quantity, the material, the source, and any notes or comments.

A parts list could look like below.

Here we can clearly see the parts list laid out, the part number on the left, the part name, quantity, material, source, and then room for any notes or comments.

Let's have a check.

Identify the three missing elements on the parts list table.

Pause the video.

Great, let's check.

The first missing word was part number in column one.

Column three, the missing word was quantity, which means the number, and the final missing word in column four was material.

Well done.

Below is a description of what could be included in a parts list.

A part number is a number that you assign to one component in your design.

The part name and description is the name or description of the part for reference.

For example, side or top.

The quantity is the amount you need of this specific component.

Material is the specific material name including the relevant dimensions.

The thickness of a sheet of MDF would be relevant here.

For example, 12 millimetre thick MDF sheet.

The source, which is where the material is being sourced from.

And finally, note/comments, which is space for further details such as cost or stock form limitations.

Stock form refers to the form that a material is available in, for example, sheet or dowel, rod or tube.

A parts list along with an orthographic projection of a design can inform manufacture.

Here we can see a parts list, a plan projection, a front projection, dimensions, an isometric view, the side projection, and the title block.

balloons can be used to identify parts in a drawing.

Balloons connect a specific component in a drawing to its corresponding entry in the parts list.

Here we have an example of a balloon symbol with a reference number.

Here, the parts of the product are identified with different balloons.

Here we have a check.

Name this symbol.

Pause the video.

Great, let's check.

That's right, it's a balloon symbol.

Well done.

Task A.

Here is an illustration of a bicycle.

Identify using balloon symbols with a reference number five separate components on the bike.

An example has been given.

And part two, complete the parts list below for the five components identified on the bicycle.

Pause a video and have a go.

Wonderful.

Let's check.

Here, five different parts have been identified using balloons.

Did you get something similar? And here we can see a completed parts list for the bicycle.

Part one is the tyre and there are two of those made from rubber.

The notes asked the question, would spare tyres be needed? Part two is the saddle outer cover.

There are one of those made from leather, and the comments, synthetic leather could be used to reduce costs.

Part number three, the main frame.

There are one of those and it's made from aluminium.

The comments state the material could be mild steel to consider cost.

Part four, the handlebar grip.

There are two of those made from silicon, and the material could be made from rubber.

Part five is the pedal, and there are two of those made from nylon, and the material could be aluminium.

Well done.

We move to the second part of our lesson today, creating a parts list.

Below is a design for an accessible herb planter, and details concluded about the manufacturing.

The materials include 18 millimetre MDF sides, 18 millimetre dowel, fabric pockets, and construction method is wasting and fabrication.

The steps in creating a parts list are to identify the separate components in your design.

Use balloons to support this.

Part one is the side and part two is the dowel.

We can also see each part drawn as a two dimensional drawing as well as identified on the three dimensional drawing.

Let's have a check.

A component is A, a single part of a larger product, B, a finished product, or C, an amount.

Pause the video.

Wonderful.

Let's check.

That's right, it's A, a single part of a larger product.

The second stage of creating a parts list is to use an orthographic projection to get a clear understanding of the dimensions for each component.

Here we have an orthographic projection of the herb planter.

Part one is an MDF side piece, and part two is the dowel.

Let's have a check.

What can be used to support knowledge about component dimensions? Is it A, an isometric view, B, an orthographic projection, C, a perspective view, or D, an exploded drawing.

Pause a video and have a go.

Great.

Let's check.

That's right, it's B, an orthographic projection.

Well done.

The third part of creating a parts list is to construct a parts list table by adding the relevant headings and the correct amount of rows for the amount of components, For example.

The fourth stage is to populate the parts list table.

For example, this accessible herb planter, part number one is the side.

The quantity is two.

There are two sides made from MDF and the source are timber suppliers.

The notes include check quality, ensure the edges have not been split.

Part number two is dowel, and the quantity is four.

There are four of those in the design.

The material is dowel and the source is the timber suppliers.

The notes state that we must check the diameter with a vernier gauge.

Part number three is the fabric pockets.

There are three of those made from ripstop nylon, and the source is the fabric suppliers.

The notes include check the quality, visually inspect the role.

The fifth stage in creating a parts list is to add the parts list table to the relevant drawings so that manufacturers have all the information to start manufacturing.

We can see here an orthographic projection with its isometric view and a parts list.

Task B, using a previous design that you have created.

Identify the separate components using balloon symbols.

This can be a CAD drawing or a sketch by hand.

And part two, using the table below, write a parts list for the design listing The separate components.

Pause the video.

Wonderful.

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

Here we can see part one and part two identified with balloons on the isometric drawing, and they correspond to parts one and two on the parts list.

Here we can see an isometric drawing identifying the different parts of the herb planter design.

Part number one is the side.

There are two of those made from MDF.

Part two is the dowel, and there are four of those made from dowels.

Part three is the fabric pockets.

There are three of those made from rip stop nylon.

Well done.

Here we have a summary of our learning today.

A parts list is a structured document outlining the components needed to assemble a product.

It enhances accuracy, efficiency, and cost effectiveness in manufacturing, aiding in the preparation of all design components, not just purchased ones.

By specifying materials and quantities, a parts list helps identify errors from earlier design stages.

Presenting the parts list in a table improves organisation clarity and accuracy.

Key table elements include part number, name, description, quantity, material, source, and notes.

A parts list along with an orthographic projection of a design can inform manufacture.

Well done and thank you for joining me today.
