ENVIRONMENTALLY CONSCIOUS DESIGN (ECD) PRIMER
DESIGN FOR X
Different criteria that are not focused primarily on the product function are introduced in modern design practice. Developed product has to satisfy functionality criteria as a basic condition, but also has to satisfy many additional criteria that can develop product success or failure. The paradigm for these additional considerations is called Design for X, and according to T.E. Graedel and B.R. Allenby (1995) following ideas can be used for "X":
Assembly (A): "The consideration of assimilability, including
ease of assembly, error-free assembly, common part assembly, and so on",
Compliance (C): "Consideration of the regulatory compliance required for manufacturing and field use, and including such topics as electromagnetic compatibility",
Environment (E): This component of DFX, and the philosophy on which it is based, is a principal subject of this primer,
Manufacturability (M): "The consideration of how well a design can be integrated into factory processes such as fabrication and assembly",
Material Logistics and Component Applicability (MC): "The topic focuses on factory and field material movement and management considerations, and the corresponding applicability of components and materials",
Order ability (O): "The consideration of how the design impacts the ordering process from the customer perspective, and corresponding manufacturing and distribution considerations",
Reliability (R): "The consideration of such topics as electrostatic discharge, corrosion resistance, and operation under variable ambient conditions",
Safety and Liability Prevention (SL): "Adherence to safety standards and design to forestall misuse; thus the prevention of costly field or at service centers",
Serviceability (S): "Design to facilitate initial installation, as well as repair and modification of product in the field or at service centers",
Testability (T): Design to facilitate factory and field testing at all levels of system complexity: devices, circuit boards, systems, and so forth.
This is summarized in the following Figure.
