FMEA Hunter Boundary Diagram Introduction
During the development of new products or design change, FMEA uses the boundary diagram (block diagram or B diagram) to determine the scope of analysis, and analyzes the components and their interfaces within the scope of analysis, as well as external interfaces with customers, manufacturers, service providers, etc., and displays the physical and logical relationships between various system elements of the product through the boundary diagram.
FMEA Hunter boundary diagram provides powerful editing capabilities, and is a sharp tool for determining the scope of analysis and conducting structure analysis and interface function analysis.
1、 FMEA Hunter Boundary Diagram creation
Through FMEA Hunter Boundary Diagram software, it is easy to draw beautiful and practical graphics.
1. Define the analysis scope. The analysis object of this example is the starter;
2. Identify external components and parts and internal components and parts;
The external components are engine support, switch, battery/power cord, flywheel.
The internal components are electromagnetic control system, DC motor, transmission system, housing, single clutch and fork.
3. Identify the interface functional;
The types of interface functional relations are: physical connection, one-way energy transfer, two-way energy transfer, one-way information exchange, two-way information exchange, one-way material exchange, two-way material exchange, human-machine interaction;
The relationship scoring is classified as follows: 2: Interaction is necessary to realize the function 1: Interaction is beneficial, not absolutely necessary to realize the function 0: Interaction does not affect the function -1: Interaction has negative impact, does not hinder the function -2: Interaction must be prevented in order to play the function
2、 FMEA Hunter loads the structure tree to the boundary diagram
Read the structure information of the structure tree into the boundary graph, as shown in the following animation
3、 FMEA Hunter boundary diagram interface function confirmation
Batch modify the type, description and rating of interface function, and determine whether to generate functions by confirming the identification.
4、 FMEA Hunter boundary diagram generation structure and function
Generate the corresponding structure tree and function from the structure and interface function in the boundary diagram, as shown in the following animation
