design criteria

For each of our target audiences we identified the design criteria. The design criteria provides the framework for designers to brainstorm and create prototypes that align with the needs and preferences of the target audience.

Below are the design criteria for our ‘typical family’.
Easy to clean

No smell and enough space to move around, read news, stand-up and open door

Lifespan of 4-5 years

Can self-build but willing to have some parts purchased

Child-friendly and safe to use – hole not too big

Not ecosan – do not want to handle waste

Low cost


Here is what the prototype session came up with.
