組み立てる and 分解: from parts to a whole and back to parts
Compare assembling a bookcase with taking a clock apart. Examining the inside after disassembly does not establish completed repairs or reassembly.
Build the whole from parts
組み立てる, read くみたてる, means assemble or construct. 説明書を見ながら本棚を組み立てた。 says that someone assembled the bookcase while looking at the instructions.
Read the direction of assembling the whole. The action is reported, while later inspection results or the installation place require other information.
Take the whole apart and examine it
分解, read ぶんかい, means disassembly. 壊れた時計を分解して中を調べた。 says that someone took the broken clock apart and examined its inside.
Disassembly and examination are completed actions. They do not establish that the clock was repaired or put back together.
A condition and another constructed object
この棚は分解すれば車にも積める。 says that the shelf can also be loaded into a car if it is disassembled. Disassembly is a condition and loading a possibility.
集めた情報を順序立てて一つの物語に組み立てる。 describes arranging the collected information into one story in sequence. 組み立てる is not limited to assembling physical parts.
Does 時計を分解して中を調べた。 establish that repair and reassembly are finished?
Show the answer and why
No. Taking it apart and examining the inside are completed. Repair and reassembly need separate information.
