Authors propose a method to classify the antipatterns, allowing their further definition for manual and automatic usage. We apply antipatterns in quality assessment as a negative quality reference. This enables counting and measuring similarity to predictable errors (antipatterns), automatic identification of erroneous structures found in mechanica...

... each phase of the machine's lifetime it is possible to identify and meaningfully apply the method of detecting similarities to known antipatterns [3,4,9] to increase the overall quality of the process. As in other phases, the antipatterns can be identified in designs of incorrect feature values (Fig. 4), relations between feature values (Fig. 5), and structural errors (Fig. 6). Feature value based antipatterns, are ones that are easiest to identify and correct. The incorrectness of the design arises from assigning a wrong value to a feature of an element. Because such wrong value changes the properties of the element, and such a change has a negative effect on the function of ...

... at the relations in the construction and between many feature values. The incorrectness of these antipatterns arise from negative properties observed after combining multiple elements. These sometimes implicit relations between parts of the construction, define the final fitness of the design for the intended function. In the example below (Fig. 5) the welding should be placed at the end of the corpse, but depending on its position with regards to elements and this placement can be correct or an antipattern. This positioning problem is caused by the difference in how the forces will act on the welding and how well the weld will hold the structure ...
Context 3
... drawings (traditionally used to represent mechanical designs) create a set of implicit relations that can be noticed only when applying expert knowledge or computer simulation [7]. This limitation is directly related to the incompleteness and lack of contextual information (i.e. fitness for assumed function). In case of the weld positioning (Fig. 5) the drawing is missing the information on kinetic forces that will be affecting the weld. Having these represented in the drawing, the antipattern could be reduced to detection of limited strength of the welding joint. In the structural example below (Fig. 6) the designer has defined the slope of the gearbox's floor simply by ...
