Abstract
The purpose of this paper is to improve the efficiency of engineering challenges solving through the application of optimal solution scheme. The paper describes various schemes of identification of engineering and physical contradictions in engineering systems when solving engineering challenges: linear and subdivided, sequential and cyclic.
The research showed that the application of a sequential linear scheme provides getting of the most cost-effective engineering solution, but decreases the feasibility of obtaining optimal solution. The application of sequential subdivided or cyclic linear scheme spends more time for engineering solution obtaining, but increases the feasibility of obtaining optimal solution. Maximum feasibility of obtaining optimal solution is achieved when using cyclic subdivided scheme, although the time expenditure in this case will also be maximum.
The paper gives an example of obtaining solutions of the problem of temperature decrease when processing part by grinding using the methods of technical creativity when applying various schemes of finding solutions. The scheme used in the example doubles the number of solutions on stage 2 (direct problem solution, without application of technical creativity methods), stage 3 (determination of system utility which should be stored), stage 6 (detection of physical contradiction), and stage 7 (engineering solutions getting). As a result, we get two direct solutions, define four utilities, respectively formulate four engineering contradictions and four ideal solutions, formulate eight physical contradictions, and when eliminating these contradictions we get 16 engineering solutions, and then, analyzing the advantages and disadvantages of each solution, choose the optimal one.
The study of methods for solving engineering problems using the methods of technical creativity within the framework of the educational process proved that it is appropriate to consider both linear and subdivided schemes of obtaining solutions in order to allow students to compare their advantages and disadvantages. The experience shows that the students get the most interesting engineering solutions when using subdivided scheme.
