Abstract: Abstract The preceding chapters traces the transition from abstract functional descriptions to concrete product concepts. Central is the identification of physical, chemical, or biological effects that realize defined functions. These are mapped in an effects–function matrix, supporting systematic technology selection while revealing interactions, efficiencies, and disturbance variables. Design emerges as a negotiation between potential and limitation, where effect carriers, geometries, and transmission paths determine feasibility. Conceptual design translates effects into workable structures guided by clarity, simplicity, safety, and sustainability. Different archetypes, e. g. working-path and surface design, inside-out or outside-in approaches, standard-component use, and symmetry or scaling illustrate how internal requirements and external constraints shape form. Managing side effects such as heat loss, vibration, or environmental impact is essential to maintain efficiency and durability. Sound concepts minimize unnecessary energy conversions and force transmissions while enhancing robustness and longevity. To broaden the solution space, methods like SCAMPER, generation development, and heuristic design principles are introduced: short force paths, uniform stress, balanced loads, tailored stiffness, redundancy, and self-protection. Finally, emissions and EcoDesign are treated as integral design dimensions. Approaches such as Design for X and the “ten golden rules” demonstrate how ecological, economic, and social factors must inform conceptual design from the outset.
