The invention provides an improved design method of a table top water purifier base with TRIZ applied. Five invention principles (including: number 3, 7, 8, 27, and 40) recommended by TRIZ are used for guiding technological innovation of an original product, so that a relatively satisfied ideal solution of the improved design is obtained, and the novel table top water purifier base with a counterweight iron member is formed. The base comprises a stainless steel housing of the water purifier base, counterweight iron blocks and permanent magnets are embedded in the housing, and an ABS injection molding body is inlaid and injected in counterweight iron block cavities; the water purifier base is organically compounded by four materials; and the base and related parts are assembled into a novel table top water purifier. The improved design based on TRIZ maintains basic functions of the original product, and an inflow magnetization function is increased and manufacture cost is reduced.

The invention relates to a method and device for improving the reliability of a tool magazine system. The method includes: step 1: using a fault analysis method to analyze potential faults of the tool magazine system to obtain key failure modes; step 2: based on the TRIZ analysis method, establishing A contradiction matrix, extracting a reliability improvement direction corresponding to the key failure mode in the contradiction matrix, and performing reliability improvement according to the direction.

The invention discloses a TRIZ-based guidance method for the condition maintenance of substation equipment, including the steps of establishing a guidance model for the condition maintenance of the substation equipment: setting the TRIZ invention principle matrix, and collecting various state quantities of the condition maintenance of the substation equipment to be guided Each parameter in the empirical value sequence of the TRIZ invention principle domain, obtain the mapped discrete sequence value of the state quantity reconstruction, obtain the complete correlation coefficient between the state quantity and the TRIZ invention principle, and construct the guidance model of the substation equipment; and use variable The steps of the electric equipment guidance model to guide the substation equipment: collect the parameters of various state quantities of the condition-based maintenance of the substation equipment to be guided and the actual sequence of the principle domain of the TRIZ invention, and obtain the actual mapping discrete sequence of the reconstruction of the state quantity Value, obtain the complete correlation coefficient between the state quantity and the TRIZ invention principle and obtain the guidance result of the substation equipment. The invention improves the accuracy of regular evaluation results of the working states of No. 1 and No. 2 substation equipment of the 220KV substation of the power grid.

The invention discloses a maintainability qualitative design method in the product design stage, comprising the steps of: establishing a maintainability design obstacle tree for a design target; performing qualitative analysis on the established maintainability design obstacle tree, and analyzing the minimum cut set of the maintainability design obstacle tree and the minimum path set to obtain the conflict vector of the design goal; obtain the corrected maintainability conflict matrix according to the TRIZ conflict matrix, determine the deterioration parameters and improvement parameters of the maintainability design conflict matrix, and establish the mapping relationship between the invention principle set and the product design feature set; Based on the revised maintainability conflict matrix of TRIZ, the principle understanding vector of TRIZ is obtained, and then combined with the obtained conflict vector, the relationship matrix between the design conflict vector and the principle understanding vector is obtained, and the corresponding conflict vector-principle understanding vector relationship equation of the conflict design system is established , to help design decisions. The present invention provides a method for resolving conflicts between maintainability design requirements and other quality design features.
