C.1. Construct a logical plan outlining the steps and justified use of resources to create a low-fidelity prototype of the hand tool.
- Logical Plan: Develop a step-by-step sequence of actions required to build the prototype. This plan should be clear, sequential, and realistic. It should include:
- Preparation: Gathering materials, setting up workspace.
- Marking Out: Transferring dimensions from drawings to materials.
- Cutting/Shaping: Methods for forming primary shapes.
- Joining/Assembly: Techniques for connecting parts.
- Finishing: Basic surface treatments (e.g., sanding, smoothing).
- Quality Control Checkpoints: Brief notes on what to check at various stages.
- Justified Use of Resources: For each step or for the overall prototype, explicitly justify the choice of:
- Specific Tools: Explain why a particular tool (e.g., "craft knife for precision cutting of foam," "hot glue gun for rapid assembly and temporary adhesion") is chosen over others for specific tasks or materials.
- Prototyping Materials: Justify the selection of accessible materials (e.g., "modeling clay for rapid ergonomic form exploration and grip feel") linking the material property to its prototyping purpose.
- Safety Considerations: Integrate safety procedures relevant to the tools and materials being used (e.g., "Always cut away from the body," "Wear safety goggles when using X tool").
Detailed Explanation
In this section, students are required to create a detailed plan for constructing a prototype of their hand tool. The plan should be logical and include all necessary steps for construction, such as preparation, marking out dimensions, cutting and shaping materials, assembling parts, finishing touches, and checking for quality at various stages. Additionally, for each step, students must justify the tools and materials chosen, explaining why each is appropriate for that specific task. Safety procedures should also be highlighted to ensure a safe working environment.
Examples & Analogies
Think of constructing a prototype like following a recipe in a kitchen. Just as you gather ingredients and utensils before you start cooking, in prototyping, you gather your materials and tools first. Each step in the recipe corresponds to a task in your planβlike mixing, boiling, or baking. If you decide to substitute an ingredient or change the cooking method, you need to explain why that change will still lead to a delicious dish, similar to justifying your choice of materials or tools while building your prototype.
