Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0045] A system analysis method based on the TRIZ object field analysis tool focusing on the system boundary, such as figure 1 shown, including the following steps:

[0046] Step 1: Take all system components associated with the system problem to be analyzed as the scope of system components to be analyzed;

[0047] Step 2: Identify the near-boundary components of the system and the supersystem according to the contact surfaces of the system components and the supersystem components. The schematic diagram of the system boundary is as follows figure 2 shown;

[0048] The super system refers to the system formed by the external environment of the current system;

[0049] Step 3: Based on the near-boundary components of the system, draw the connection diagram of all components of the system, and determine the type of effect that the near-boundary compo...

Abstract

The invention discloses a system analysis method achieved by focusing system boundaries on the basis of a TRIZ object field analysis tool. According to the method, a clear direction and a basis are provided for system analysis by focusing the system boundaries, ignoring a large number of non-boundary assemblies and paying close attention to near boundary assemblies. Near boundary assembly pairs on the boundaries are described and analyzed by introducing classical and widely-applied object field models and object field analysis in the TRIZ theory, and the system problems are better described and analyzed by playing the advantages of a definition model and an analysis model of the tool. A user can systematically analyze a system through help of the analysis procedures and the detailed analysis steps which are provided by the method, and a method and procedures with the objective operability are provided for system analysis.

Description

technical field [0001] The invention belongs to the field of system analysis in the machinery industry, and relates to a system analysis method based on a TRIZ object field analysis tool focusing system boundaries. Background technique [0002] System analysis is the key to finding system problems (such as the system not working properly or the system is not operating well), and it is an essential step before optimizing the system. For a complex mechanical system with a large number of components, it is difficult to analyze the system conveniently and accurately, and the accumulation of experience and professional knowledge is very demanding. Most engineers rely on personal work experience and subjective judgment when analyzing the system, and sometimes they can only conduct blind searches, lacking systematic guidance methods. [0003] At present, the widely used system analysis method is the function analysis method, which splits the functions of the system and analyzes th...
