39 Common DFX Concepts


DFX indicates the design dealing with every process of NPI cycle. X could represent any process or feature of NPI cycle. As a modern integrated design method, it shall take every factor of product into account, including performance, quality, manufacturability, assimilability, testability, service and price, etc., aiming to get it right at the first time.

Common DFX includes following:

DFA: Design for Assembly. Design the product based on the analysis of component fit to promote assembly efficiency.

DFC: Design for Compatibility,ensuring the connectivity between the designed product and other devices, as well as the compatibility after product upgrading.

DFC: Design for Compliance, ensuring the designed product conforms to relevant standard/ regulations and market access.

DFC: Design for Cost, intending to reduce product cost as much as possible on the premise of fulfilling user demand.

DFD: Design for Diagnosability, to improve the capability of locating faults when product failure occurs.

DFD: Design for Disassembly, making product easy to be disassembled, convenient for recycling;

DFD: Design for Discard, focusing on the design of service strategy and promoting replacing faulty parts rather than repairing;

DFE: Design for Environment, aiming to reduce the bad impact of NPI cycle on the environment;

DFE: Design for Extensibility, making it easy for the product to add new features or modify the existing functions.

DFEE: Design for Energy Efficiency, intending to reduce the power consumption of product and improve its energy efficiency.

DFF: Design for Flexibility, to ensure the flexibility of framework interface so as to cope with the system change.

DFH: Design for Humanity/Ergonomics, emphasizing on fulfillment of people’s spiritual needs affection needs.

DFI: Design for Installability, aiming to improve the efficiency of engineering installation, commissioning and acceptance.

DFI: Design for interoperability, to ensure the connectivity between products and other devices.

DFL: Design for Logistics, intending to reduce the logistics cost including packaging, transportation, customs clearance and so on;

DFM: Design for Migrationability, ensuring the portability and upgradability of product system.

DFM: Design for Maintainability, ensuring high maintainability and efficiency.

DFM: Design for Manufacturability, intending to improve first pass yield of product.

DFPDesign for Packaging.

DFP: Design for Portability, making it easy for system porting between platforms.

DFP: Design for Performance, focusing on the improvement of system by considering time delay, throughput rate and resource utilization when designing the product.

DFP: Design for Procurement, putting more emphasis on the convenience and low cost of material procurement on the premise of fulfillment of product features and performance.

DFP: Design for Postponement, supporting postponing the fulfillment of differentiated demand to after-sale link.

DFQ:Design For Quality.

DFR:Design for Recycling, to enable the product easy to be recycled.

DFR:Design for Reliability, ensuring the product could fulfill user’s demands, including decrease in fault and fault’s impact, as well as restoration after fault.

DFR:Design for Repair, considering the convenience of product service.

DFR:Design for Reusability, enabling the product design/module be used by the subsequent version or other products, thus to improve the efficiency of development.

DFR:Design for Reusability, considering more about the protection of human safety during product usage.

DFS:Design for Scalability, to fulfill the requirement of system capacity change.

DFS:Design for Security, to reduce the vulnerability of capital and resources, including confidentiality, completeness, availability, access control, authentication and privacy protection, etc.

DFS:Design for Serviceability, to improve the capability of system test and maintenance.

DFS:Design for Simplicity, to reduce the complexity and components of product, thus decreasing the cost of material, supply and maintenance.

DFSC:Design for Supply Chain, to promote the efficiency of supply and stock turnover, so as to reduce delivery time.

DFS:Design for Sustainability, to enable the sustainable interaction among material, production and comsuption.

DFT:Design for Testability, intending to improve the capability of fault detection, positioning and isolation of product by adding some special design into the circuit for the convenience of product test. Generally, such design would arrange more test point (exposed via) and more silk screen on the circuit board.

DFU:Design for Upgradeability, to ease the upgrading operation of product.

DFU:Design for Usability, to improve the convenience, effectiveness and efficiency of usage.

DFV:Design for Variety, to balance the diversified demands of users and scale supply efficiency.

The practical product design could focus on the main design based on real needs.
