You are an engineer reviewing the production line for a new smoke alarm. The following is an extract of the FMEA that has been conducted on the product and you have been tasked with reviewing components, production and the safety of the product. Design Verification Process System Subsystem Component Potential Failure Mode and Effects Analysis (Design FMEA) FMEA Number Project III Prepared By Sylvia Wu FMEA Date 22/10/2020 Design Lead Key Date Revision Date 21/08/2021 Shay Isaac See Project III R1 Report Core Team Page 1 of 6 Potential Failure Models) Item/Function Potential Effects) of Failure Sey Potential Causesy Mechanisms) of Failure Human error Occ Action Results 81 Actions Taken Current Design Controls Det Recommende d Action(s) RPN Responsibility & Target Completion Date Sensor A A Faulty fire sensor 9 Not correctly calibrated 2 Training and verification 3 3 of testing Insufficien t volume 9 Faulty Purchase specialised calibration tool Investigate alternative alarm component Alarm component Faulty fire sensor 1 Inspection 5 component Alarm housing 3 Incorrectly cast housing 4 Inspection 2 Alarm cover breaks at first removal Replacement housing required Negotiate quality with supplier Answer the following questions: 1. You think you have a way to detect failures better. Based on the FMEA approach, which item will you focus these efforts on? Sensor A, the Alarm Component or the Alarm housing? 2. Justify your answer to question 1 above. 3. Another option you find is to improve the manufacture of the alarm housing so that the FMEA Occurence value of it breaking at first removal halves. What is the new RPN for the Alarm housing item?
