The Smart Trash Can
It's connected to the internet and to your phone
It knows when it's full and needs to be emptied
Can be connected to a hose bib for periodic cleaning
Can take itself to the curb for trash day
It can't open doors, gates, or pass through other solid obstacles without assistance
Needs to be charged periodically. Battery life provides for about 1 km of roundtrip travel distance over average terrain to the curb
Bin has a weight limit of 110 kg
There is no on-device interface except for a multi-color LED and two programmable buttons
Once items are thrown away, they cannot be retrieved
Who is my user?
Who is my client, as opposed to the customer that will use the product?
What type of trash can? Is it a wastebasket or something larger?
What are the physical dimensions of the trash can? What is the volume limit?
How does it maneuver in two (or possibly three dimensions)?
What triggers it to go to the curb on trash day? Is it interoperable with the trash collection company's machinery?
What are the non-functional requirements (sustainability/supply chain/MSDS)?
What specific type of trash? Compost? Recycling? Landfill?
Are all of the features intended to have equal weight or priority?
Why is taking out the trash considered to be burdensome?
How could the experience of taking out the trash be improved?
What would make a trash can "smart?"
What information does the user (and app) need to get from the trash can?
What instructions does the app need to give to the trash can?
What will encourage the user to choose a smart trash can over a regular one?
what I deduced based on the info
If it takes itself to the curb on trash day, then it must mean the 'trash can' is large enough to warrant being mobile and meant to be used outside.
If the weight limit is 110 kg (242 lbs), then that implies a weight heavier than a human can handle, and therefore a lifting mechanism will be necessary to empty out the trash.
If a lifting mechanism is needed, the trash can will need to be interoperable with the trash collection company's machinery.
If items cannot be retrieved once they're thrown away, then the security of waste is crucial and only authorized persons (presumably the garbage men) can retrieve the garbage.
If it can't open doors or go through obstacles, something or someone will have to clear the path.
who is involved?
Asks for a trash can
Designs the trash can
Produces the trash can
Collects trash on a schedule
More people = more trash
Uses the trash can every day
Challenge brief implies a family by alluding to the conflict over responsibility over the trash. Resolving this conflict leads to a more robust solution.
There are many possibilities for a multi-person household but the nuclear family presents the most interesting interpersonal dynamics. It can be parent to parent, parent to child, parent as intermediary between the children.
i need data!
1. From start to finish, will you tell me how you dispose of trash?
2. What kinds of trash do you usually throw out?
3. Do you separate your trash?
4. How often do you leave trash at the curb for pickup?
5. What are the approximate dimensions of your trash can?
6. Who takes out the trash?
7. How do you feel about having to take out the trash?
8. What don't you like about taking out the trash?
9. What do you like about taking out the trash?
10. If you could change anything about the trash, what would you change?
let's cluster our data!
"It looks dirty seeing the garbage without the lids."
What goes into the trash?
"I do it, mostly. The kids sometimes take it out but rarely."
"It's dirty, it leaks, and it smells. I don't want it to drip on me."
"Anything non-recyclable or non-compostable."
Pick up schedule
"I bring it out once a week on Monday nights."
"Once a week."
Transporting the trash can
"I don't like having to walk out."
"Even though I can roll it out, it's still heavy!"
"I wish it cleans itself!"
"I wish I didn't need to walk out with it!"
Throwing the trash is a two-step process. First, the user gathers all trash from the wastebaskets inside the house. Second, the user then puts them all in the bigger trash can that is taken to the curb.
The indoor trash is much more visible and it's apparent when it needs to be transferred to a bigger trash can.
It's the outdoor can that is "out of sight, out of mind" for which more feedback would be helpful to the family.
Trash cans get heavy, that's why they are stored on the ground floor (commonly in the garage) to be rolled or easily carried to the curb .
Forgetting to take the trash out is not uncommon.
Trash cans are usually cleaned after being emptied.
who's the persona?
Linda is a 39-year old mother living in suburban Walnut Creek. She and her husband Jamie have a 15-year old daughter and a 9-year old son. As a busy working mom, she has a lot of responsibility, working outside the home and taking care of the kids. With so much to keep track of, even the smallest chores, such as taking out the trash, can be annoying. It's heavy, stinky, and grimy from all of the leaking garbage.
Would like to have minimal interaction with the trash can
Wants to make taking out the trash easier for her and the kids
Would like an effective way to clean the trash can
what's Linda's journey like?
