B2.1.10 Ideation Techniques

In the early stages of ideation, more ideas is always better. The goal is not to find the perfect solution immediately — it is to explore the full range of possibility before narrowing down.

Research by design theorist Linus Pauling supports this principle:

Many of the most innovative design solutions in history emerged from ideas that initially seemed impractical, absurd, or irrelevant — but which, when developed or combined with other ideas, revealed unexpected possibilities.

During ideation, criticism is suspended. Ideas are generated freely without immediate evaluation. The moment a designer begins judging ideas as they emerge — "that won't work", "that's too expensive", "that's been done before" — the creative flow stops.

Judgement comes after ideation — not during it.

Ideation is not a solo activity of the mind — it is a generative, cumulative process. Each idea generates the possibility of another. A partial idea can inspire a complete one. An idea that doesn't work in one context might work perfectly in another.

The principle is simple: "Yes, and..." — acknowledge every idea and build upon it.

Ideation is creative — but it is not undirected. Every idea generated should be evaluated against a simple question: "Does this address the defined problem for the defined user?"

Ideas that are creative but irrelevant to the problem statement are not useful ideation — they are distraction. The design specification serves as a creative compass — keeping ideation purposeful without constraining it.

What is it?

Brainstorming is the most widely known ideation technique — a rapid, free-flowing generation of ideas in response to a defined problem. Ideas are recorded as quickly as possible, without filtering or judgement.

How to do it:

1. Write your problem statement or HMW question prominently at the top of your workspace

2. Set a time limit — typically 10 to 20 minutes

3. Generate as many responses as possible — write, draw, or speak every idea, however partial or impractical it seems

4. Record everything — no idea is discarded during the session

5. After the session, review and cluster related ideas, identifying promising directions

Brainstorming variations:

Real-World Example:

When IDEO was commissioned to redesign the hospital patient experience for a major US healthcare provider, their brainstorming sessions were conducted from the patient's perspective — "How might we make every moment of the hospital stay feel less frightening and more human?"

Ideas generated ranged from the immediately practical (clearer signage, warmer lighting) to the seemingly absurd (patients controlling their room environment via smartphone, staff wearing plain clothes rather than uniforms). Several of the initially absurd ideas became central to the final design solution — demonstrating that suspending judgement during brainstorming allows genuinely innovative ideas to surface.

What is it?

Mind mapping is a visual ideation technique that organises ideas as a branching diagram — starting from a central concept and expanding outward into related ideas, sub-ideas, and connections.

Unlike linear brainstorming, mind mapping reveals the relationships and connections between ideas — often generating new ideas at the intersections of different branches.

How to do it:

1. Write your central design challenge in the middle of a large sheet of paper and circle it

2. Draw primary branches outward — each representing a major dimension of the problem (e.g. grip, force, aesthetics, materials, mechanism)

3. From each primary branch, draw secondary branches — specific ideas within each dimension

4. Continue expanding branches as far as ideas flow

5. Look for connections between branches — ideas at the intersection of two branches often yield the most innovative solutions

Real-World Example:

When designers at Ergotron were developing their universally adjustable monitor arm, mind mapping from the central challenge "How might we make digital workspaces accessible to all users?" generated branches exploring:

• Physical adjustment — height, tilt, rotation, extension

• Force requirements — gas-assisted, spring-loaded, friction-based mechanisms

• User diversity — seated, standing, wheelchair-using, visually impaired users

• Materials — aluminium extrusions, polymer joints, cable management integration

• Aesthetics — industrial, domestic, healthcare-appropriate appearances

The intersection of the wheelchair-using users branch and the physical adjustment range branch revealed a specific design gap — no existing monitor arm provided sufficient downward tilt range for wheelchair users at lower seated heights. This intersection insight became a key design innovation in the final product.

What is it?

SCAMPER is a structured ideation technique that uses seven specific creative thinking prompts to systematically generate new ideas by modifying, adapting, or reimagining existing products or concepts.

SCAMPER is particularly powerful for redesign projects — where the goal is to improve or transform an existing solution rather than invent from scratch.

How to use SCAMPER:

Apply each prompt systematically to your existing product analysis findings or your initial design concepts, recording every idea generated — however partial or impractical.

Real-World Example:

The development of the OXO Good Grips range can be understood through the SCAMPER lens:

• Substitute: Substitute hard metal/plastic handles with compliant Santoprene rubber

• Modify/Magnify: Magnify handle diameter from 12mm to 38mm — distributing grip force across a larger surface area

• Adapt: Adapt the fin-grip pattern from bicycle grips to kitchen tool handles

• Eliminate: Eliminate the need for excessive grip force through handle geometry that provides mechanical advantage

• Reverse: Reverse the design priority — instead of optimising for manufacturing efficiency, optimise for user physical capability

Each SCAMPER prompt generated a specific design direction that was explored, tested, and — in several cases — incorporated into the final design solution.

What is it?

Morphological analysis is a structured ideation technique that breaks a design challenge into its key functional components and generates multiple options for each component independently — then systematically combines options from different components to create complete design concepts.

It is one of the most powerful techniques for generating a large number of genuinely diverse concepts in a systematic way.

How to do it:

1. Identify the key functional components of your design — the major sub-problems that must be solved

2. Create a morphological chart — a matrix with components as rows and multiple possible solutions for each component as columns

3. Generate multiple ideas for each component independently

4. Create complete concepts by selecting one option from each row and combining them

5. Each unique combination represents a distinct design concept worth exploring

Example morphological chart — universal jar opener:

From this single morphological chart, selecting one option from each row generates 4 × 4 × 4 × 4 × 4 = 1,024 theoretically distinct design concepts — ensuring genuine diversity in the ideation output.

In practice, designers use morphological analysis to identify 6 to 10 promising combinations that represent genuinely different design directions, which can then be developed further through sketching and modelling.

Real-World Example:

When Dyson was developing their digital motor technology for universal application across vacuum cleaners, hair dryers, and hand dryers, their engineering teams used morphological analysis to explore combinations of motor type, airflow geometry, filter system, and housing form. The systematic exploration of component combinations revealed configurations that would not have been reached through simple brainstorming — leading to several of Dyson's most innovative product architectures.

What is it?

Biomimicry is an ideation technique that looks to nature for design inspiration — studying how living organisms solve problems through millions of years of evolutionary refinement, and applying those solutions to human design challenges.

Nature has solved many of the same challenges that designers face — grip, adhesion, structural strength, thermal regulation, water management, and sensory communication — through elegant, efficient, and sustainable mechanisms.

How to use biomimicry in ideation:

1. Identify the core functional challenge in your design problem

2. Ask: "How does nature solve this challenge?"

3. Research natural organisms and systems that address similar challenges

4. Extract the principles behind the natural solution — not the form itself

5. Apply those principles to your design challenge

Examples of biomimicry in universal design:

Real-World Example:

The development of Sharklet — a surface texture inspired by the microscopic geometry of shark skin — demonstrates biomimicry applied to universal design in healthcare. Shark skin prevents bacterial adhesion through microstructure geometry rather than chemical treatment. Applied to hospital surfaces and medical equipment, Sharklet technology reduces bacterial infection rates — a universal safety benefit derived entirely from natural observation.

In product design, the Velcro fastening system — inspired by the hook-and-loop geometry of burdock seed burrs — has become one of the most significant universal design innovations in clothing and equipment fastening, enabling independent dressing for users with limited fine motor control who cannot manage buttons or laces.

What is it?

Analogical thinking is an ideation technique that consciously transfers solutions from one domain or context to a completely different design challenge. It asks: "Where has a similar problem already been solved — and how might that solution be applied here?"

Unlike biomimicry — which specifically looks to nature — analogical thinking looks across all human-designed systems, products, industries, and contexts for transferable solutions.

How to use analogical thinking:

1. Identify the core functional challenge in your design

2. Ask: "What other domain faces the same fundamental challenge?"

3. Research how that domain has solved the challenge

4. Extract the principle behind the solution

5. Transfer the principle to your design context

Examples of analogical thinking in universal design:

Real-World Example:

The EpiPen auto-injector — a life-saving device designed for self-administration of adrenaline during allergic reactions — was developed using analogical thinking borrowed from military auto-injector technology designed for field use by soldiers who may be injured, panicked, or wearing gloves.

The military context had solved the same fundamental challenge: enabling a critical medical intervention by a non-expert user, under stress, with potentially compromised fine motor control. Transferring the spring-loaded, cap-remove-and-press mechanism from military to civilian medical context produced a device that could be successfully operated by users ranging from young children to elderly adults — a powerful universal design outcome achieved through systematic analogical thinking.

What is it?

Random stimulus is an ideation technique that breaks habitual thinking patterns by introducing a completely unrelated word, image, or object as a creative prompt — forcing the designer's brain to make unexpected connections between the stimulus and the design challenge.

It is particularly effective when other ideation techniques have produced a cluster of similar ideas — when creative thinking has become trapped in familiar territory.

How to use random stimulus:

1. Select a random word (from a dictionary, a randomly opened book, or a random word generator)

2. List the qualities, characteristics, and associations of that word

3. Force connections between those qualities and your design challenge

4. Record every connection generated — however tenuous it seems

Example — random stimulus for a jar opener redesign:

Random word: "Umbrella"

Qualities and associations of an umbrella:

• Opens and closes with a single hand gesture

• Radial expanding geometry

• Thin when closed, wide when open

• Provides protection from external force

• Collapsible and portable

• Automatic spring-release mechanism

Forced connections to jar opener design:

• Single-hand gesture opening → A jar opener that opens with a single pinch gesture rather than requiring grip and rotation

• Radial expanding geometry → A jar opener using expanding radial arms that grip the lid from inside the rim rather than around the outside

• Automatic spring-release mechanism → A spring-loaded mechanism that applies consistent opening torque without requiring sustained user force

• Thin when closed, wide when open → A flat, credit-card-profile opener that expands into an operational form when deployed

After ideation, group related ideas into clusters — identifying the major design directions that have emerged. This reveals the landscape of possibilities without immediately eliminating any direction.

For each promising idea or direction, ask:

• "Does this idea address the defined problem for the defined user?"

• "Is this response appropriate to the context identified in the problem statement?"

• 
  

Ideas that cannot be connected to the problem statement are noted but set aside.

Screen remaining ideas against the essential criteria of the design specification:

• Does this idea have the potential to meet the essential functional requirements?

• Are there any essential criteria that this idea fundamentally cannot address?

Ideas that fail to meet essential criteria are rejected or significantly modified.

From the evaluated ideas, select three to five promising concepts that represent genuinely different design directions — not just variations on the same approach. These become the design concepts to be developed, modelled, and further evaluated in subsequent stages of the design process.
