解説
問 61
Incorrectア
Barrier-free design is a design and improvement approach that aims to remove, after the fact, the barriers felt by specific groups such as the elderly or people with disabilities. Its focus is on “dealing with” existing barriers, so its starting point differs from universal design, which is “designed from the outset so that diverse people of all kinds can use it.” It does not fit the question’s intent of aiming from the very beginning for the inclusiveness of “as many people as possible.”
Incorrectイ
Fail-safe is a reliability-design approach in which a system or device is designed so that, even if it fails or malfunctions, it minimizes harm and shifts to a safe-side state. It has nothing to do with the diversity of users or comfortable usability, and its domain differs from the intent of the question.
Incorrectウ
Foolproof is a design approach in which the mechanism is made so that erroneous operation is impossible in the first place, so that no danger or malfunction occurs even if the user operates it incorrectly. Its purpose is to prevent operating mistakes, not a design philosophy aiming for “comfortable use by diverse people,” so it is incorrect.
- エ
正解 The correct answer is エ “Universal design.” Universal design refers to a design philosophy for products, environments, and services that are intentionally made, from the very start, to be comfortably and fairly usable by as many people as possible, regardless of differences in culture, language, age, or gender, or the presence of disabilities and differences in ability. The statement in the question—“a design that aims to be comfortably usable by as many people as possible regardless of differences or the presence of disabilities”—matches the definition of universal design exactly, so エ is correct.
ここがポイント
- Universal design = a design philosophy that aims, from the very start, to be comfortably and fairly usable by as many people as possible, regardless of culture, language, age, gender, presence of disabilities, or differences in ability.
- Watch out for confusion: barrier-free means “removing existing barriers after the fact,” fail-safe means “shifting to the safe side upon failure,” and foolproof means “preventing erroneous operation”—each has a different purpose.
