“…The theory of inventive problem solving (TRIZ, Russian abbreviation) and the space -time LT -table of physical quantities are two different dialectical tools used to solve inventive problems in engineering systems (ES) [1]. TRIZ is a heuristic methodology, created on the basis of the discovery of the law of evolution of ES in patent documentation [2].…”

“…This system can be correlated with the International System of Units of Measurement (SI) [6][7][8]. The main disadvantage of Bartini's LT-table of physical quantities is the vagueness when it comes to its possible practical application in solving inventive problems [1]. The authors tried to compensate for this vagueness in their works [9][10][11][12].…”

“…The focus of his research is on finding a connection between the Inventive Problem Solving Algorithm (ARIZ, Russian abbreviation) as the most powerful tool of TRIZ and Bartini's LT-table of physical quantities. Only in the works [1,3,[13][14][15][16] there is a correlation established between Altschuller's contradiction matrix as the most popular and most represented tool of TRIZ and Bartini's LT-table of physical quantities. By critically considering and upgrading these two tools, the LT-contradiction matrix was created as a new tool of inventology that offers solutions for 3210 different contradictions that may appear in inventive problems [1,3,13,15,16].…”

“…These are the criterion of measurability of all physical quantities that it encompasses, the criterion of their invariance regardless of the coordinate system in which the event takes place and the criterion of proportionality according to which everything changes in order to remain unchanged. This inventory tool includes 64 parameters presented in the form of the general expression L m T n [1,3,13,15,16]. The LTcontradiction matrix has 7 fields of ES evolution that are defined by the value of the evolutionary gene s m+n = ±(0,1,2,3).…”

The spatial-temporal LT-contradiction matrix is an inventology tool that enables exact calculations of certain parameters in an engineering system through mathematical-physical modeling. It objectifies the decision-making process and creates the preconditions to finding an adequate resource (X-element) with a higher probability, and thus to reach a higher degree of ideality solution (HDIS) of an inventive problem as well. Any engineering system that generates an inventive problem can be described using the LT-contradiction matrix. By crossing the appropriate parameters in the LT-contradiction matrix, with the help of the differential geometry of the tensor, a qualitative-quantitative analysis and calculation of relevant degree all contradictions that exist in the inventive problem can be performed. After that, the path to finding the physical characteristics of the X-element in the mathematical-physical model is facilitated, i.e. finding a real resource that will enable a HDIS of the inventive problem in an engineering system.

A Conflict Solving Process Based on Mapping between Physical Parameters and Engineering Parameters

With the continuous expansion of system scale, the parameter coupling of the system is prominent. Due to limitations in knowledge and experience, it is difficult for designers to objectively analyze the interaction relationship between parameters, resulting in the low accuracy of engineering parameter selection, hence affecting conflict solving. In order to improve the accuracy of engineering parameter selection and the efficiency of conflict solving, this paper proposes a conflict solving process based on mapping between physical parameters and engineering parameters. First, the physical parameters related to the components of the system function model are extracted, and dimensional analysis is used to construct a physical parameter logical network. Secondly, the physical parameter change path related to the problem in the physical parameter logical network is found, and the physical parameter sets corresponding to both conflicting parties are obtained. Then, the engineering parameters corresponding to conflicts can be selected through the mapping model between physical parameters and engineering parameters, which is trained by a neural network with the sample data of physical parameter sets and engineering parameters in existing cases. Finally, Theory of Inventive Problem Solving (TRIZ) tools are used to solve conflicts, and the final design scheme is obtained through evaluation. The feasibility and effectiveness of the proposed method are verified by redesigning a bulk traditional Chinese medicine dispenser.

This study proposes an evaluation framework to explore the solution concepts generated by inventive design approaches in the concept generation phase of the engineering design process. The concept generation phase significantly impacts producing inventive solutions, as a failure at this stage can lead to time-consuming redesign and expensive rework without any solution. The proposed framework is focused on solving two problems at this stage: first, how to represent a solution concept that is not an obvious product but rather a rough idea capable of guiding designers to produce inventive solutions. And second, how to analyze the solution concepts to evaluate and compare with others. The evaluation framework is based on the classical Gero's function, behavior, and structure product modeling formalism. The capability of the proposed evaluation framework is initially tested through its application to solution concepts generated by inventive design approaches like the Russian Theory of Inventive Problem Solving TRIZ.
