Overview

By the end of the lesson, pupils should be able to:

  • Understand the concept of subcomponent design.
  • Understand decomposition and recomposition.
  • Use the Design Heuristic tool to design parts of ideas or products.

Year Groups

All ages

Resources

Computer, projector, printed handouts, pencils.

Lesson Structure

1. Introduction to Subcomponent Design

  • Design Heuristics can be used to modify individual components or parts of existing products or ideas.
  • This enables designers to improve individual parts of a design.

2. Subcomponent Design

  • Design by parts or components is a method which comes from engineering.
  • Decomposition: is the process of breaking something apart into smaller pieces that can be independently addressed.
  • Recomposition: Is the process of taking the redesigned subcomponents and putting them back together into the whole object/system.

3. Examples of Subcomponent Design

  • Students should be able to see how subcomponent design is EVERYWHERE and can sometimes be described as attention to detail!!

Lesson Activities

Activity 1

Purpose: Subcomponent Design Familiarisation

Subcomponent Design – Bicycle: The students will be asked to select 5 subcomponents of a bicycle and redesign each individual subcomponent.

Activity 2

Purpose: Decomposition

This activity will enable to understand the concept decomposition by redesigning the subcomponents of a seating device.

Activity 3

Purpose: Recomposition

This activity will enable to understand the concept recomposition by redesigning decomposed subcomponents of the seating device from activity 2.

Activity 4

Subcomponent Design – Superhero:
This activity will see the students redesign prescribed and optional subcomponents of their superhero.
