DFR - Moving from 4 Traditional to 33 Innovative Ways to Improve Reliability

Problem: The traditional four (4) methods for improving reliability; 1) High design safety margin, 2) Reduction in component count or system architectural complexity, 3) Redundancy, and 4) Back-up capability, are often ignored or perceived as being excessively costly in weight, space claim as well as money.

Solution 1: Discussed here are the practical and very cost effective methods for achieving improved reliability by Functional Interface Stress Hardening (FISHtm or FISHingtm). The Author has been able to apply FISH to eliminate 70-92% of unscheduled equipment downtime, within 30-60 days, for more than 30 of the Fortune 500 and many other large companies which utilize automation controls, computers, power electronics and hydraulic control systems.

Solution 2: From Structured Innovation the 33 DFR Methods & R-TRIZ Tool can be used to grow or improve reliability, via rapid innovation. The R-TRIZ tool) is provided so that users can instantly select the best 2, 3 or 4 of these 33 Principles for eliminating the PoF, thus solving any given reliability constraint or problem.

Reliability is the key driver of minimal warranty support costs. Reliability is a key driver trustworthy design, product reputation and expanding market share. Reliability is key to bottom line profitability. DFR is likewise essential to supporting missions of the US Army.
