This paper presents a conceptual engineering framework for designing product systems with intrinsic resistance to reverse engineering. Abstract Modern consumer and industrial products are increasingly vulnerable to replication due to the widespread availability of analytical techniques, manufacturing knowledge, and global supply chains. Traditional protection strategies such as patents and trade secrecy often provide incomplete protection once products reach the market. This paper introduces a conceptual engineering framework for designing product systems with intrinsic resistance to reverse engineering. The framework proposes entropy-informed architectural principles and introduces the concept of Replication Friction, defined as the structural difficulty associated with accurately reconstructing a product system. Through analysis of system entropy, component interdependence, and informational asymmetry, the study outlines how product complexity can be deliberately structured to increase replication barriers while maintaining functional efficiency. The proposed framework offers insights applicable to consumer chemical systems, industrial formulations, and engineered consumer goods where intellectual protection through design becomes a strategic engineering objective.
