The benefits obtained from inconvenience, which we call the FUrther BENEfit of a Kind of Inconvenience (fuben-eki), are now being recognized in many research fields. To design systems that embody such benefits, this paper proposes fuben-eki cards. A set of them consists of principle cards and benefit cards. Each principle card shows a tenet to make a system inconvenient that leads to the positive outcomes shown on each benefit card. The results of evaluation experiments show that principle cards increased the number of ideas when they were used for the divergent thinking processes of a fuben-eki system design.
