Usage tips
Compound word
'Innenleben' (inner life / inner workings) is a compound noun made up of the adverb 'innen' (inside) and the noun 'das Leben' (life). So it literally means 'the life inside' and is used both for people and for devices.
EXAMPLE
Das Buch gibt einen tiefen Einblick in das Innenleben der Hauptfigur.
The book gives a deep insight into the inner life of the main character.
Context clue
You can easily distinguish the two meanings: If people speak of the 'Innenleben' (inner life) of a person, they mean their thoughts and feelings. If people speak of the 'Innenleben' (inner workings) of a machine or organization, they mean its internal functioning.
EXAMPLE
Er spricht nur selten über sein Innenleben.
He rarely talks about his inner life.
Typical collocations
In the psychological sense, 'Innenleben' (inner life) is often described with adjectives such as 'reich' (rich), 'komplex' (complex), or 'geheim' (secret). Common verbs are 'verstehen' (to understand), 'offenbaren' (to reveal), or 'Einblick geben in' (to give insight into).

Innenleben vs Aufbau
structure / assembly
'der Aufbau' and 'das Innenleben' can both describe how something is organized internally. 'der Aufbau' is more general: you can use it to describe the structure of a text, a device, a company, or a plan. 'das Innenleben' more specifically means what happens inside a device, machine, or even an organization, and how the parts work. Learners may confuse the words because both point to structure. 'Aufbau' fits when you mean the order or organization. 'Innenleben' fits more when you are looking inside something or want to explain its inner workings.
