Consumer-Friction Product Design begins with concrete inconveniences rather than a generic desire to launch a product. The founder records what fails during actual use, watches how other customers handle the same situation, and converts each recurring problem into a feature requirement. Shay Mitchell described wanting a large bag without losing small items, keeping shoes separate, and stopping a bag from sliding off a carry-on; those needs became a key leash, separate compartment, and trolley pass-through. The method then tests the whole proposition against competing constraints: the product should look good, perform its job, remain durable, and stay within the intended price range. The output is a product whose details can be explained as solutions, not decoration.

Core principles
- 01Start with problems you experience as a real customer
- 02Translate each frustration into a purposeful feature
- 03Observe how people use existing products in context
- 04Balance appearance, function, durability, and price
How to run it
- 1
Live the customer journey
Use the category as a customer and note where available products create repeated inconvenience, risk, or compromise.
Pro tip Capture the problem at the moment it occurs rather than relying on a later general impression.
Watch out A personal annoyance is only a starting signal, not proof that a wider market shares it.
- 2
Observe real use
Watch how people carry, store, move, and compensate for existing products in the environment where they are used.
Pro tip Look for improvised workarounds; they often reveal an unmet requirement.
- 3
Define the unmet combination
Identify the combination of appearance, function, reliability, and price that no current option delivers together.
Watch out Do not call a market gap solely because one preferred colour or minor detail is unavailable.
- 4
Map problems to features
Assign a specific design response to every important friction and explain exactly how it improves use.
Pro tip If the team cannot explain why a feature exists, reconsider it.
Watch out Too many narrowly useful features can make a product cumbersome.
- 5
Prototype the system
Sketch and sample the complete product, then test whether its features work together without undermining cost or usability.
Pro tip Test in the real use environment, not only on a presentation table.
In the wild
Mitchell wanted a large travel bag but disliked losing keys, mixing shoes with other belongings, and having the bag slide off a carry-on. She translated those problems into a key leash, a separate compartment, and a trolley pass-through while keeping the overall look restrained.
→ The observed travel frictions became defining product features rather than a lightly modified generic bag.
After becoming a parent, Mitchell found that carrying a drink while managing two children consumed a needed hand. A dedicated drink compartment in a small sling addressed that everyday constraint.
→ A new life-stage friction informed a practical feature for short daily journeys.
Common mistakes
Designing from category conventions
Copying what products in the category usually include misses the workarounds and frustrations that create differentiation.
Adding function without restraint
More compartments or mechanisms are not automatically better; each feature should solve a meaningful problem without making the product harder to use.
Is it for you?
Best for
It is best for founders who personally understand a category and can observe customers using its products.
Not ideal for
It is not ideal when the founder has neither firsthand experience nor reliable access to customer behaviour.

“to be a solution based company”
“I was drawing up a design that sort of met the needs that I couldn't find out there.”
