01 / Refill systems
A refill system is designed at the second purchase
The permanent case gets the photograph. Compatibility, replenishment, and the empty-state experience determine whether it stays in use.
A notebook for looking closer
Ten field notes on the decisions behind everyday products. Each one pairs a specific design question with a sketch and objects from the collection.
01 / Refill systems
The permanent case gets the photograph. Compatibility, replenishment, and the empty-state experience determine whether it stays in use.
02 / Solid & waterless
Replacing a bottle with a bar removes one container—and introduces a storage problem between uses.
03 / Compact objects
Capacity is only one dimension of portability. The unused spaces around an object can matter just as much.
04 / Concentrates
When a product ships without its final dilution, mixing instructions become part of its physical design.
05 / Reuse
The first use is half the story. Carrying, cleaning, drying, and remembering create the next use.
06 / Screen-free
Removing a display shifts work to objects, labels, sound, and memory. Those choices deserve the same scrutiny as an app.
07 / Transformation
The tote and the backpack are easy to photograph. The transition is where the design earns its place.
08 / Modularity
A growing collection of parts is useful only if people can tell what connects—and what will still connect later.
09 / Materials
An unusual input material and a workable end-of-life route are different claims. A good product page separates them.
10 / Design critique
A simple test for product novelty: identify the behavior that changes, then identify the burden that comes with it.
