Defining Filtering Protective Suit Ideality using a Mathematical-Modeling Method

Abstract

<jats:p>Real systems approach the ideal by solving technical and physical contradictions. Optimization of system engineering (SE) is achieved when the problem is solved at the level of technical contradiction. When the problem is solved at the level of physical contradiction, the idealization of SE is achieved. Two possible ways of achieving ideality are described in this paper. The expansion process flows at the level of SE (i.e., idealization of another type), and the reduction process flows at the subsystem level (i.e., idealization of the first type). A procedure of mathematical modeling is presented for determining the level of ideality as a criterion for filtering protective suit (FPS) effectiveness, which can be used as a standard for determining the ideality of any SE.</jats:p>

Compatibility between TRIZ contradiction matrix and LT-units system

“…Testing of the protective properties of FPS against the effects of HTS was conducted by the total process of penetration of Syperite vapours through their materials. During hours of examination, in all models of FPS, output contamination density did not reach the value of 4 μg/сm 2 , which fulfilled the set request from standards [4]. Comparison of FPS-M3 and FPS-M4, in terms of surface mass of outer and inner layer, shows that FPS-M4 has 30 g/m 2 greater surface mass and 80 g/m 2 of the inner layer.…”

“…However, from a practical point of view, it is necessary to determine values of key parameters that are important for calculating the IFS. The highest ponder belongs to the heart frequency as the most important physiological parameter which directly impacts the safety (life) of the user, followed by surface mass, wearing comfort and price [4]. FPS-M3 model reached ideality of 69.98%, and model FPS-M4 -66.01%.…”

“…Applying the methods of optimization of the listed parameters, FPS-M4 was chosen as an overly better means. However, applying the formula for calculating ideality showed that the difference in mass, as an unwanted parameter, was so much better for the FPS-M3 that this parameter was the prevailing factor in deciding the greater total ideality of this means [4]. Increasing ideality of both FPS models can be achieved by increasing their individual parameters.…”

“…The Filtering Protective Suit (FPS) is a filtering means that protects user's body from high toxic materials (HTM) [4]. This paper deals with experiments that were conducted to test the basic physical and mechanical characteristics of FPS-M1-M3 (manufactured by "Trayal Korporacija", Krusevac, Serbia) and FPS-M4 (manufactured by "Proizvodnja Mile Dragić", Zrenjanin, Serbia).…”

“…In order to overcome a TC in most other methodologies, system optimization is performed. However, TRIZ strives to overcome every problem by achieving the Ideal Final Solution (IFS) [3][4][5]. In case of applying the Contradiction Matrix, by intersecting the parameters that are being improved with those that deteriorate automatically, it is proposed in the cells of the matrix to use several different TRIZ principles out of a total of 40 defined, the application of which would most probability resolve the TC.…”
