Performance objectives

• Identify a problem that needs a design solution.
• Develop a detailed plan for creating a product.
• Create a prototype of your design.
• Evaluate the effectiveness of your design.
• Present your solution and explain its relevance.

Lesson summary

This lesson focuses on a critical stage in the design process: transforming a chosen idea into a detailed, workable plan. In our previous lessons, we learned how to identify problems and select the best possible solution. However, a good idea is not enough to create a successful product. We need a clear blueprint. Think of a master kente weaver who has a pattern in mind, or a carpenter who is about to build a new piece of furniture. They don't just start cutting and joining; they have a detailed plan. This lesson teaches us how to create that plan.

Lesson notes

This lesson is about turning your selected design idea into a formal plan. We "develop the solution" by creating the documents that anyone could follow to make the product. This involves three main parts: Working Drawings, a Specifications List, and a Plan of Work. A. Working Drawings: Communicating the Design Visually

A working drawing is a technical drawing that provides all the information needed to manufacture a product. It's the language of designers and makers. For JHS Career Technology, we focus on two main types: Orthographic Projection: This is a way of drawing a 3D object in 2D. We look at the object from specific angles and draw what we see. The three main views are: Front Elevation: What you see when you look at the object from the front. Plan (or Top View): What you see when you look down on the object from directly above. End Elevation (or Side View): What you see when you look at the object from the side (usually the right or left side).

These drawings must be accurate and include dimensions (measurements like length, width, and height) so the maker knows the exact size of each part.
