Four complex biotechnology products/product systems(a protein purification system,a bioreactor system,a surface plasmon resonance biosensor,and an enzymatic glucose analyzer)are analyzed using conceptual design principles.A design model well-known in mechanical system design,the Hubka-Eder(HE)model,is adapted to biotechnology products that exemplify combined technical systems of mechanical,electronic,and biological components,here referred to as bio-mechatronic systems.The analysis concludes that an extension of the previous HE model with a separate biological systems entity significantly contributes to facilitating the functional and systematic analyses of bio-mechatronic systems.
