Engineering MakingResearch First, Then Ideate Wide: From Prior Art to a Concept Wall
Atlas stands at a workbench covered in printed patent diagrams, interview notes, and a cork wall blanketed in colorful sticky-note concept sketches, gesturing toward two clusters of ideas.
- Explain why background research on prior art and users comes before generating solutions
- Distinguish prior-art research from user data and identify what each tells a designer
- Apply at least two structured ideation methods to widen a solution space
- Evaluate why deferring judgment during brainstorming produces more concepts
Key terms
- Prior art
- Existing patents, products, and published solutions an engineer studies to find gaps before inventing.
- User data
- Observations and interviews from the people who will actually use a design, revealing real needs over stated wants.
- Defer judgment
- The brainstorming rule of generating ideas first and postponing all criticism to a separate later stage.
- SCAMPER
- An idea-prompting checklist: Substitute, Combine, Adapt, Modify, Put to other use, Eliminate, Reverse.
- Morphological chart
- A grid listing each function with several options so combinations can be systematically mixed and matched.
Two Research Streams Before Ideation
Prior-art and user research answer different questions and both must precede invention. Prior art tells you what already exists, where current solutions fall short, and which approaches are legally protected, so you target unsolved gaps rather than re-inventing a worse wheel or infringing a patent. User data tells you what real people struggle with, frequently revealing that their stated wants differ from their underlying needs. Designing from observed facts rather than from your own assumptions is what keeps a project anchored to the actual problem.
Why Deferring Judgment Widens the Space
Brainstorming's core rule, defer judgment, separates idea generation from idea evaluation on purpose. When ideas are criticized the instant they appear, contributors self-censor the unusual, risky concepts that most often hide a breakthrough, and the group collapses prematurely onto a safe, ordinary answer. Deferring judgment does not declare every idea permanently equal; it simply reserves criticism for a dedicated evaluation phase, so quantity and diversity are protected first and ruthless filtering happens afterward when there is plenty to choose from.
Structured Methods for Going Wide
Unstructured brainstorming tends to circle the same few obvious ideas, so engineers use structured prompts to force breadth. Concept sketching converts vague thoughts into comparable drawings, exposing differences words hide. SCAMPER systematically transforms an existing idea along seven distinct directions. A morphological chart decomposes the design into functions, lists multiple options under each, and combinatorially generates many candidate systems by mixing one option per function. These tools manufacture variety deliberately rather than waiting for inspiration.
Worked examples
Use a morphological chart to widen the solution space for a foldable commuter bike.
- Decompose the bike into its key functions: folding mechanism, frame material, locking method, and wheel size.
- List several options under each function, for example hinge / telescoping / breakaway for the folding mechanism.
- Recognize that one option per function combines into a complete candidate concept.
- Count the breadth: with 3 options across each of the 4 functions, the chart yields 3 × 3 × 3 × 3 = 81 distinct combinations.
- Select a handful of promising combinations to sketch and carry into later evaluation.
Answer: A 4-function chart with 3 options each generates 81 candidate concepts, dramatically widening the solution space before any evaluation.
Activity
Sort each design task into the correct stage of the early design process
Practice
Classify four given design tasks as prior-art research, user data, or a specific ideation method.
Apply three SCAMPER prompts to an ordinary umbrella and describe the new concept each one produces.
Common mistakes to avoid
- Prior-art research means copying the best product.Prior-art research finds unmet gaps to solve, and directly copying a patented design infringes intellectual property while missing the real opportunity.
- Your first strong idea is good enough to build.Committing early narrows the solution space, so better alternatives are never generated or compared against the first idea.
Check your understanding
Why do engineers research prior art before brainstorming solutions?
During a brainstorming session, why is it best to defer judgment?
A student says, 'I already know the best solution, so I don't need to sketch other concepts.' Why is this a misconception?
What is the main purpose of a morphological chart during ideation?
Recap
Good engineering research runs two streams first: prior art to find gaps and user data to ground real needs. Only then does ideation widen the solution space by deferring judgment and applying structured methods such as concept sketching, SCAMPER, and morphological charts, which deliberately manufacture many diverse concepts to choose among later.
Reflect
Think of a problem you want to solve and list one prior-art source and one group of users you would study first.
