Table 2.1 Examples of time axis design cases
No. Case name
Description
1
Message soap
A letter is embedded in the soap and when
the user washes his/her body with the soap,
the letter appears at a certain time
2
BABUBU furniture (http://shinse-i.jp/bab
ubu/)
If the bed size does not fit a baby because
of his/her growth, it is customized to a desk
by applying additional parts
3
Bonsai
Bonsai refers to potted plants grown with
special care for appreciation. A user can
tailor the bonsai to his/her taste by taking
care of it as the plant grows and the
environment changes. (https://www.bonsai

4
Copying machine
A copying machine is provided with
maintenance service in case of trouble
5
LEGO (https://www.lego.com/en-us)
By preparing different sets of LEGO
according to age, LEGO can respond to the
changes in children’s preferences
6
Wine
Wine is matured by storing it until it is
ready to drink after purchasing it
7
Skype translation (https://www.skype.
com/ja/)
As the AI learning, it leads to improve the
performance of translation technology
8
Baggage made of bamboo
Bamboo used as material of a baggage is
getting attractive as the user uses
9
Beaker pudding container (https://www.har
ioscience.com/)
By adding a measuring function in pudding
container, the container can be used as a
beaker after eating the pudding
10
Moist hair dryer: Areti (https://areti.jp/)
The dryer has the function to adjust air
volume in response to the changes in the
user’s age and season
changes because it is ambiguous. By collecting and classifying the cases of time axis
design, we made a matrix between the changes and the countermeasures as shown
in Table 2.4. This Table 2.4 shows the number of the cases corresponding to each
change and each countermeasure. Since the red cells in this Table 2.4 have enough
number of cases, we consider that the countermeasure in this cell is effective to the
change in this cell. And, we use these cells to find out design ideas in Sect. 2.6.
