Welcome
Move from a clearly defined problem to a range of possible solutions
In Lesson 02 you researched the engineering theme, evaluated evidence and defined a clearer engineering problem. The next step is to avoid jumping straight to one favourite answer and instead generate several possible engineering solutions.
Engineering creativity is not simply “having a good idea”. It combines technical knowledge, research evidence, structured thinking, sketching, comparison and purposeful development.
How can engineers generate a broad range of technically credible ideas before deciding which solutions deserve further development?
Learning Outcomes
What should you know and be able to do by the end?
Learning Aim A requires you to investigate and develop possible engineering solutions. The quality of your later comparison and feasibility study depends on having a genuine range of alternatives now.
Prior Knowledge Check
Connect research and problem definition to idea generation
Answer these three questions before beginning the main learning.
Why This Matters
Engineering creativity creates options before commitment
Once a problem is understood, there is rarely only one possible engineering response. Different mechanisms, materials, layouts, control systems and manufacturing methods can all produce different solutions.
Generating alternatives reduces the danger of locking into an idea too early. It also gives you evidence for later comparison: cost, performance, risk, manufacturability, sustainability and feasibility can only be compared when there is more than one credible option.
A workshop needs a safer way to move a 25 kg component between two benches. How many fundamentally different solution approaches can you identify before choosing one? Think beyond simply “design a trolley”.
Main Learning Content
A2 • Structured creativity and engineering solution generation
1 • Divergent Thinking First
At the beginning of solution generation, the aim is to create breadth. Do not judge every idea immediately. Generate several different approaches first, then evaluate them later. This is called divergent thinking.
Quantity First
Create several alternatives before narrowing the field.
Different Principles
Change the mechanism, energy source, layout, material or control method.
Delay Judgement
Record unusual ideas before deciding whether they are practical.
2 • Creativity Techniques
Brainstorming
Generate many possible approaches quickly.
Click to explore- Focus on the engineering problem.
- Record every useful suggestion.
- Avoid early criticism.
- Group similar ideas afterwards.
Mind Mapping
Expand the problem into functions, constraints and possible technologies.
Click to exploreBranches might include power, sensing, structure, movement, safety, materials, manufacture, maintenance and user interaction.
SCAMPER
Challenge an existing idea using seven prompts.
Click to explore- Substitute
- Combine
- Adapt
- Modify
- Put to another use
- Eliminate
- Reverse / Rearrange
Morphological Analysis
Break the problem into functions and combine different options.
Click to exploreFor a lifting device, functions might include: support load, create motion, guide motion, control movement and protect the user. Different options for each function can be recombined into new concepts.
3 • Sketch to Communicate
Early engineering sketches do not need to be perfect CAD drawings. They should communicate how the idea might work. Useful annotations include:
- main components and approximate arrangement
- direction of movement or force
- power or energy source
- materials or manufacturing ideas
- important dimensions or limits
- safety features
- advantages, concerns and questions to investigate
A concept sketch should make it possible for another engineer to understand the principle of the solution without you standing beside it explaining everything.
4 • Keep Creativity Engineering-Led
Creative does not mean unrealistic. Use the evidence from Lesson 02 to test whether an idea addresses the real problem. At this stage, a solution does not need full detail, but it should have a credible technical principle.

Smithsons • From research insight to multiple concepts
Generating alternatives for a fitness-focused product opportunity
Smithsons has identified a possible opportunity in sport and fitness. The engineering team must now avoid jumping directly to one product. Instead, they need to generate several ways of responding to the same need.
Concept A
A wrist-worn activity device using motion sensing and a compact display.
Concept B
A clip-on activity tracker focused on low mass, simple feedback and long battery life.
Concept C
A hybrid watch that keeps a traditional watch appearance but adds selected activity features.
These are not finished designs. Each is a different solution direction. What technical questions would need to be answered before deciding which concept deserves further development?
Case-study task
- Identify one strength of each concept.
- Identify one technical uncertainty for each concept.
- Suggest a fourth fundamentally different concept.
- Use one SCAMPER prompt to modify any concept.
- State which ideas should move forward to the next stage and why.
Solution Generation Activity
Create several technically different responses to one problem
Scenario: Safe Movement of a Heavy Component
An engineering workshop needs a safer way to move a 25 kg component between two workbenches positioned 4 metres apart. The route is narrow, the equipment must be easy to store and the solution should reduce manual handling.
Produce at least six possible solution ideas. They should not all be minor variations of the same trolley.
Choose one idea and use either SCAMPER or a morphological approach to generate at least three variations.
Choose your three strongest concepts. For each, list the features that should appear on an annotated engineering sketch.
Lesson Summary
Key learning from Lesson 03
1 • Generate Before You Select
Strong engineering development starts with several alternatives, not immediate commitment to one favourite idea.
2 • Use Structured Creativity
Brainstorming, mind mapping, SCAMPER and morphological analysis help engineers deliberately create new solution directions.
3 • Sketch Function, Not Decoration
Early concept sketches should communicate how an idea works, its main features and important technical questions.
4 • Stay Evidence-Based
Ideas should respond to the researched problem, stakeholder needs and known project constraints.
Lesson 04 will take the strongest concepts and begin scoping alternative engineering solutions using more detailed technical information, processes, costings and preliminary evidence.

Check answer guidance
Q1: Multiple concepts reduce early fixation and allow later comparison of performance, cost, risk and feasibility.
Q2: Examples include brainstorming, mind mapping, SCAMPER and morphological analysis.
Q3: Function, components, movement, materials, dimensions, safety features and key annotations.
Q4: A different solution changes the underlying technical approach; a minor variation only changes details such as size, colour or small features.
