This work completes Sigmund Freud's drive theory by supplying the formal mechanism he never defined. Freud correctly identified that human behaviour emerges from conflicts between opposing drives, but his model lacked a structural explanation for how these contradictions escalate, collapse, or resolve. Using the Carlo Framework, this paper introduces three missing components: the contradiction engine, the trajectory update rule, and the Reset Operator > . Together, these provide a dynamic mechanism that models repression, discharge, stabilisation, and reorganisation as predictable outcomes of drive conflict. The completed theory transforms Freud's descriptive model into a coherent system capable of representing how psychological tension evolves over time, how contradictions force structural change, and how new stable states emerge. This paper formalises the drive–counterdrive loop, defines the conditions under which it collapses, and demonstrates how the Carlo reset mechanism produces the outcomes Freud described but could not mechanise. The result is a fully structured, internally consistent model of drive dynamics.
