Detailed Design Specifications and Planning Drawings for Hand Tool
In this section, the importance of creating accurate and detailed design specifications is emphasized, as it serves as a blueprint for the development and prototyping of the chosen hand tool.
- Refined Design Specifications: Students will take the initial list of specifications created in the earlier design phase and refine them to reflect the final design decisions made during the ideation phase. Specifications will help ensure that the final product meets user needs, ergonomic considerations, and functional requirements.
- Initial Planning Drawings/Diagrams: Students will produce a series of detailed drawings that include:
- Orthographic Projections: These drawings will illustrate the hand tool from multiple viewpoints (e.g., top, front, side). They will include precise dimensions, tolerances, and material specifications for key components.
- Isometric/Perspective Views: This will provide a three-dimensional representation of the hand tool, allowing for a better understanding of its form and function.
- Sectional Views: If needed, these views will showcase internal components or specific ergonomics, ensuring that all features are clearly understood.
- Assembly Diagram: If the tool consists of multiple parts, this diagram will detail how components fit together.
Each drawing must be clearly annotated, aiding anyone unfamiliar with the design in understanding the form, function, and materials involved. The quality and detail of the specifications and drawings are crucial, as they ensure clarity throughout the prototyping phase and enable proper implementation of the design.

Based on the chosen design, refine and finalize the specifications. These will be more precise than the initial list in Criterion A.4, directly reflecting the decisions made during ideation. They will serve as the blueprint for prototyping.
Detailed Explanation
In this chunk, you learn how to refine your design specifications for your chosen hand tool. This means taking the initial ideas you had and sharpening them into specific, clear guidelines that your prototype will follow. These refined specifications are crucial because they help everyone understand exactly what the tool needs to do and what it should be like, ensuring that it meets the user's needs accurately.
Examples & Analogies
Think of this process like cooking a recipe. Initially, you might have a general idea of what dish you want to make. But as you start preparing, you need to fine-tune the ingredients (like how much salt to add or what specific spices) to get the flavor just right. The refined specifications for your tool are like the precise measurements listed in a detailed recipe that ensure your dish turns out amazing!

Produce clear and accurately dimensioned orthographic (multi-view) drawings (e.g., front, top, side views) that show the precise shape, size, and internal/external features of the hand tool. Include essential dimensions, tolerances (if understood at this stage), and material call-outs for key components.
Detailed Explanation
Here, you will create technical drawings of your hand tool. These drawings should include multiple views of the tool so that someone else can understand its design just by looking at the pictures. You should indicate precise measurements for every key part of the tool. This way, anyone who wants to build your tool will have all the information they need to replicate its design accurately.
Examples & Analogies
Imagine putting together a piece of IKEA furniture. The assembly instructions include various drawings that show different angles of the item, like the front, side, and top views, along with measurements. These drawings help you understand how the pieces fit together. Similarly, your drawings and diagrams are like the instructions, ensuring that anyone can follow your design and build your tool accurately.
Isometric/Perspective Views

Include an isometric or perspective drawing to provide a comprehensive 3D representation of the chosen design, aiding overall understanding.
Detailed Explanation
In this part of the process, you need to create a 3D representation of your tool. An isometric or perspective drawing helps show depth and volume, giving viewers a better sense of how the tool looks and feels from various angles. This is important as it allows for a more intuitive understanding of the design than flat drawings can provide.
Examples & Analogies
Think about how a video game character is drawn in a 3D space. Instead of only showing a flat picture, the designers create a model that can be viewed from any angle, which makes it easier for players to appreciate the character's appearance. Your isometric or perspective views play the same role, making your hand tool design easier to visualize in three dimensions.
Sectional Views and Assembly Diagrams
