設計: designing a bridge and a desk’s storage purpose
Compare the act of designing in 設計して with a design characteristic in 設計になっている. Read the model built after a bridge design and the desk’s purpose of providing more storage.
The act of designing a bridge
設計 (せっけい) means design or planning. 「小さな橋を設計して模型を作った。」 means “I designed a small bridge and built a model.” 設計して expresses the act of designing the small bridge.
The object built after the design is a 模型, or model. Connect the bridge as the design’s target with the model as the object made, keeping their roles separate.
A desk’s design characteristic
「この机は収納を増やす設計になっている。」 means “This desk is designed to provide more storage space.” The desk has a design intended to provide more storage space.
In 設計になっている, 設計 names the desk’s design characteristic. The sentence expresses a storage purpose without stating a measured increase in actual storage.
An action or an intended function
設計して presents the designing action followed by making a model. 設計になっている presents the current design of the desk. The same word has different roles within the sentences.
For the bridge example, follow the design’s target and the object subsequently made. For the desk example, follow the storage purpose served by its design.
What was made in the bridge example, and what purpose does the desk’s design express?
Show the answer and why
A model was made after the bridge was designed. The desk’s design is intended to provide more storage space, illustrating a design characteristic rather than the designing action and its resulting model.
