Sketching

✅ Why this step brings your ideas to life

You’ve brainstormed possible directions—now it’s time to sketch them out.

Concept sketches are where abstract ideas become tangible. They're not about artistic polish—they’re about communicating ideas clearly. This step is essential for exploring shape, function, assembly, and user interaction, before you commit to CAD or physical models.

Sketches allow you to compare options fast, test assumptions, and align the team around early directions.

📘 What you’ll learn

  • How to translate ideas into visual form—fast
  • How to compare multiple options side by side
  • How to get stakeholder feedback without overinvesting
  • How to explore form, function, and user interaction early

🛠️ Tools and methods

  • Rough Concepts (1–5 mins per sketch)

    Use multiple views or annotations to express the idea—not detail.

  • Sketch Pack

    Create 3–5 variations to explore different approaches to solving the problem.

  • User Storyboards

    Draw the idea in use (e.g. “open the lid”, “place on wall”) to test assumptions.

  • Dot Voting or Heatmapping

    Use group feedback to surface preferred elements or options.

⚠️ Don’t fall into these traps

  • Over-rendering. You’re not selling the design yet—keep it rough.
  • Sketching only one idea. The first idea isn’t always the best. Explore.
  • Focusing only on appearance. Use sketches to test mechanism, ergonomics, usability.
  • Skipping annotation. A simple sketch with a note is clearer than a perfect sketch alone.

💡 Advice from the field

“We didn’t think the ‘folding frame’ idea would go anywhere—until we saw it drawn next to the others. It was the simplest and most logical.”

– Product Design Lead, Urban Mobility Company

💡 Use contrasting directions: big vs. small, bold vs. minimal, complex vs. elegant. Differences fuel better conversations.

✍️ Quick self-check

  • Have we sketched at least 3 concept directions?
  • Have we explored both form and function?
  • Can we explain each idea clearly with annotations?
  • Did we get feedback before progressing to CAD?

🎨 Visual concept (optional)

Illustration: A review wall showing three large sketch sheets labeled “Concept A”, “B”, and “C”. Each sheet shows perspective views, callouts, and arrows. A small team is adding dot votes or sticky notes with feedback like “Simplest assembly” and “Too bulky”.

Visual shows how rough sketches enable fast, focused comparison of early ideas—without the polish of final design.
