     The reading value is utilized as a foundation for prioritizing the sequence of consideration for the groups, in which the system reading value constructed by different models gives designers lots of options to perform the reading, so as to acquire the undesired result features of the prioritized consideration.

PATENT DESCRIPTION
BACKGROUND 
       [0001]    The invention relates to decision process, and in particular to TRIZ decision process of a clustering method. 
         [0002]    This section is intended to introduce the reader to various aspects of the art, which may be related to various aspects of the present invention, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present invention. Accordingly, it should be understood that these statements are to be read given said understanding, and not as admissions of prior art. 
         [0003]    In creating a design, designers are often confronted with contradictory problems due to different realistic conditions, or are indulged in deep thought, resulting in research and development (R &amp; D) delays and inefficient use of time. In order to facilitate the creative process, abstract-idea-based design concepts and engineering problem-solving techniques have become objective trends for designers. The intelligent system implemented by this practice shall help improve the design process. 
         [0004]    Conventionally, when using a TRIZ matrix, manpower is required for determining improving features and no-worsening features in advance, thereby finding several inventive principles, and accordingly determining better inventive principles. It is difficult for a less-experienced user to determine no-worsening features and priority among inventive principles. 
       SUMMARY 
       [0005]    Certain aspects commensurate in scope with the claimed invention are set forth below. It should be understood that these aspects are presented merely to provide the reader with a brief summary of certain forms the invention might take and that these aspects are not intended to limit the scope of the invention. Indeed, the invention may encompass a variety of aspects that may not be set forth below. 
         [0006]    A clustering TRIZ analysis method is provided. The method comprises steps of: (1) constructing cluster elements according to features and inventive principles of a TRIZ matrix by associating items with similar physical meanings as one cluster; (2) calculating display times of each cluster according to improved feature cluster and inventive principle cluster, calculating the display times of the corresponding inventive principle cluster and the no-worsening feature cluster according to a TRIZ contradiction matrix, and storing results of the calculation in a database; (3) determining discrimination values of each model according to the display time results in step (2), and using the discrimination values to determine a priority order of the clusters.

     DETAILED DESCRIPTION 
       [0013]    One or more specific embodiments of the invention are described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers&#39; specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacturing for those with ordinary skill of the art having the benefit of this disclosure. 
         [0014]    In the following detailed description, reference is made to the accompanying drawings which form a part hereof, shown by way of illustration of specific embodiments. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that structural, logical and electrical changes may be made without departing from the spirit and scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense. The leading digit(s) of reference numbers appearing in the figures corresponds to the Figure number, with the exception that the same reference number is used throughout to refer to an identical component which appears in multiple Figures. It should be understood that many of the elements described and illustrated throughout the specification are functional in nature and may be embodied in one or more physical entities or may take other forms beyond those described or depicted. 
         [0015]      FIG. 1  shows a clustering TRIZ deciphering model, which is generally described as follows: 
         [0016]    In step S 10 , a TRIZ matrix is provided. 
         [0017]    In step S 11 , cluster elements are constructed. The cluster elements are matched with the features and the inventive principles of the TRIZ matrix, and are collated to be clusters according to similar physical meanings, as shown in  FIG. 2 . 
         [0018]    In step S 12 , display times of each cluster are calculated. The display times of the corresponding inventive principle cluster and the no-worsening feature cluster are calculated by means of the clustered improved feature cluster and inventive principle cluster, and through the TRIZ contradiction matrix, and then stored in the database, which can be a reference for the construction of each model. The details are shown in  FIG. 3 . 
         [0019]    In step S 13 , the discrimination values of each model are established. The discrimination values are matched with the display time results from the statistics in step S 12 . Furthermore, the display times are used to construct the discrimination methods of each model (including the display time model, Bayes probability model, fuzzy value model, and the combined fuzzy value and the Bayes probability model). The discrimination value acquired by the system is taken as the priority order of clusters (step S 14 ), from which designers can consider a suitable priority order of clusters for the design (steps S 15  and  16 ). The details are shown in  FIG. 4 . 
         [0020]    1. Construction of cluster elements (step S 11  in  FIG. 1 , as shown in  FIG. 2 ) 
         [0021]    Based on the likelihood of the physical meanings, the 39 features and 40 inventive principles of the TRIZ matrix are rearranged to be 13 clusters. For example, the clustering of the 40 features comprises object segmentation and extraction cluster, prior handling cluster, counteraction cluster, cluster of partial action or structural change, balance object cluster, vibration and structural dynamicity cluster, harmful factor cluster, mechanical system replacement cluster, material cluster, physical change cluster, chemical action cluster, rejection and maintenance cluster, and system combination cluster. Object segmentation and extraction cluster comprises principles of segmentation, extraction, asymmetry, prior action, cushion in advance, and dynamicity. Cluster of partial action or structural change comprises principles of local quality, spheroidality, and partial, overdone or excessive action. Mechanical system replacement cluster comprises principles of moving to a new dimension, copying, replacement of a mechanical system, use of a pneumatic or hydraulic construction, and color change. Material cluster comprises principles of substituting an expensive, durable object by an inexpensive, short-life one, flexible film or thin membrane, use of porous material, homogeneity, and composite material. 
         [0022]    Next, construction of each model is described. ( FIG. 1 , step S 13 ) 
         [0023]    (1) Display Time Model 
         [0024]    The construction process of the display time model is described as follows: 
         [0025]    Step  1 : The improved feature clusters and the inventive principle clusters having similar physical meanings are selected. 
         [0026]    Step  2 : The display times acquired from the statistics on the various clusters are calculated in accordance with the contents of the TRIZ matrix, together with the display time results from the statistics on each corresponding inventive principle cluster made by each improved feature cluster. 
         [0027]    Step  3 : The acquired display times are used as a reference for users in arranging the priority order of the inventive principle clusters. The display times are arranged in proper order as shown in Table 1. 
         [0028]    Step  4 : The moving object cluster is acquired. The moving object cluster is the display times acquired from the statistics on the corresponding inventive principle clusters and no-worsening feature clusters of the improved feature clusters in accordance with the contents of the TRIZ matrix, together with the display time results from the statistics on each corresponding no-worsening feature cluster made by each corresponding inventive principle cluster of each improved feature cluster. 
         [0029]    Step S 5 : The acquired display times are used as a reference for users in arranging the priority order of the no-worsening feature clusters. Taking the moving object feature cluster as the considered improving factor, the display times of the object segmentation and extraction inventive principle clusters and the corresponding no-worsening feature clusters can be acquired, as shown in Table 2. 
         [0030]    (2) Bayes Probability Model 
         [0031]    The construction process of the Bayes probability model is described as follows: 
         [0032]    Step  1 : The improved feature clusters and the inventive principle clusters having similar physical meanings are selected. 
         [0033]    Step  2 : The required display probability is acquired in accordance with the contents of the TRIZ matrix, together with the display time results from the statistics on each corresponding inventive principle cluster (I j ) made by each improved feature cluster. The Bayes probability (P(C i |I j )) of each inventive principle cluster is realized through the Bayes theorem equation, which is expressed as equation (3-1).

         [0034]    In equation (3-1), “a” denotes the total number of inventive principle clusters, i denotes the number of improved feature clusters, and i=1, 2, . . . ,10, j denotes number of inventive principle clusters, and j=1, 2, . . . ,13, P(C i ) denotes the display probability of improved feature cluster (Ci) in the entire TRIZ table, and P(I j |C i )denotes the display probability of inventive principle cluster (Ij) in the improved feature cluster. 
         [0035]    Step  3 : The acquired Bayes probability value is taken as the priority order, which is taken by users as a reference for priority order in the no-worsening feature clusters. A table of the probability value of each corresponding inventive principle cluster of the moving object improved feature cluster is formulated, as shown in Table 3. 
         [0036]    Step  4 : The required display probability is acquired in accordance with the contents of the TRIZ matrix, together with the statistics on the display times of each corresponding no-worsening feature cluster (I′ j ) made by each corresponding inventive principle cluster (C′ i ) of each improved feature cluster. The Bayes probability value P′(C′ i |I′ j ) of each no-worsening feature cluster is realized through the Bayes theorem equation, which is expressed as equation (3-2):

         [0039]    (3) Fuzzy Value Model 
         [0040]    The construction process of the Fuzzy value model is described as follows: 
         [0041]    Step  1 : The improved feature clusters and the inventive principle clusters having similar physical meanings are selected. 
         [0042]    Step  2 : The fuzzy relationship value of each element in each feature cluster is defined by 10 feature clusters having similar physical meanings in accordance with the concept of the fuzzy object oriented model. For example, a certain feature in the cluster is used as a major consideration factor for defining the fuzzy relationship value (F_value) between the major considered feature factor and other related features. In the moving object cluster, if the weight of moving object (simply referred to as “WMO,” hereinafter) is taken as the major consideration target, then the fuzzy relationship value with the length of moving object (simply referred to as “LMO,” hereinafter) is 0.6, the fuzzy relationship value with the area of moving object (simply referred to as “AMO,” hereinafter) is 0.7, and the fuzzy relationship value with the volume of moving object (simply referred to as “VMO,” hereinafter) is 0.8. The fuzzy relationship values of other elements are shown in Table 5. 
         [0043]    Step  3 : The display times (I_F_value i ) of the added fuzzy value of each cluster and the total display times (S_F_value j ) of the added fuzzy values of the entire cluster required by the system is acquired in accordance with the contents of the TRIZ matrix, together with the statistics on the display times (N i ) of each corresponding inventive principle cluster made by the improved feature cluster, and from the fuzzy relationship value (F_value i ) between the display times (N i ) and the elements in the improved feature cluster acquired through the fuzzy object oriented model. The correlation is shown as in equation (3-3, 3-4):

         [0049]    (4) Combined Fuzzy Value and Bayes Probability Model 
         [0050]    The construction process of the combined fuzzy value and Bayes probability model is described as follows: 
         [0051]    Step  1 : The improved feature clusters and the inventive principle clusters having similar physical meanings are selected. 
         [0052]    Step  2 : The fuzzy relationship value of each element in each cluster is defined by  10  feature clusters having similar physical meanings in accordance with the concept of the fuzzy object oriented model. The practice is to take a certain feature in the cluster as a major consideration factor for defining the fuzzy relationship value (F_value) between the major considered feature factor and other related features. In the moving object feature cluster, if the WMO is taken as the major consideration target, then the fuzzy relationship value with the LMO is 0.6, the fuzzy relationship value with the AMO is 0.7, and the fuzzy relationship value with the VMO is 0.8. The fuzzy relationship values of other elements are shown in Table 6. 
         [0053]    Step  3 : The display times (I_F_value i ) of the added fuzzy value of each feature factor and the total display times (S_F_value i ) of the added fuzzy values of the entire cluster are acquired in accordance with the contents of the TRIZ matrix, together with the statistics on the display times (N i ) of each corresponding inventive principle cluster made by the improved feature cluster (C m ), and from the fuzzy relationship value (F_value i ) between the display times and the elements in the improved feature cluster acquired through the fuzzy object oriented model. The correlation is shown in equation (3-7, 3-8).

         [0054]    In equations (3-7) and (3-8), “a” denotes the total number of inventive principle clusters. 
         [0055]    Table 7 shows the display times of the corresponding object segmentation and extraction cluster of each feature factor in the moving object cluster. Table 8 shows the fuzzy relationship values that take WMO as the major element in the moving object cluster. Table 9 shows the display times (I_F_value i ) of the added fuzzy value of the corresponding object segmentation and extraction cluster of each feature factor in the moving object cluster and the total display times (S_F_value i ) of the added fuzzy values of the WMO-based object segmentation and extraction cluster. 
         [0056]    Step  4 : The display probability (P(F_I n |C m )) of the added fuzzy value is obtained by using the total display times (S_F_value i ) of the added fuzzy values of the entire cluster acquired in Step  3 ,. The relation equation is shown in equation (3-9). The Bayes probability value (P(C m |F_I n )) of the added fuzzy value of each inventive principle cluster is acquired through the Bayes theorem equation. The Bayes theorem equation is expressed as equation (3-10).

         [0057]    In equations (3-9) and (3-10), “m” denotes the number of improved feature clusters, and m=1, 2, . . . ,10, “n” denotes the number of inventive principle clusters, and n=1, 2,  . . . ,13, P(C m ) denotes the display probability of the added fuzzy value of the improved feature cluster (C m ) in the entire TRIZ matrix, and P(F_I n |C m ) denotes the display probability of the added fuzzy value of the inventive principle cluster (F_I n ) in the improved feature cluster. 
         [0058]    Table 10 shows the representative values of P(C m ) and P(F_I n |C m ) of the corresponding object segmentation and extraction cluster of the moving object cluster. Table 11 shows the probability value (P(C m |F_I n )) of the corresponding object segmentation and extraction cluster of the moving object cluster. 
         [0059]    Step S 5 : The acquired probability value of the added fuzzy value is taken as the priority order, which is the user&#39;s referential priority order in the inventive principle cluster. Table 12 shows the fuzzied probability value of each corresponding inventive principle cluster of the moving object cluster which takes WMO as the consideration target. 
         [0060]    Step  6 : The display times (N′_I_F_value i ) of the added fuzzy value of each cluster and the total display times (N′_S_F_value j ) of the added fuzzy values of the entire cluster are acquired in accordance with the contents of the TRIZ matrix, together with the statistics on the display times (N′_N i ) of each corresponding no-worsening feature cluster (C′ m ) made by each corresponding inventive principle cluster of the element in each improved feature cluster, and from the fuzzy relationship value (F_value i ) between the display times (N′_N i ) and the elements in the improved feature cluster acquired through the fuzzy object oriented model. The correlation is shown in equation (3-11, 3-12).

         [0062]    Table 13 shows the display times of the corresponding physical property cluster of the feature factor in the moving object cluster that takes WMO as the major consideration factor. Table 14 shows the fuzzy relationship values of the feature factor in the moving object cluster that takes WMO as the major consideration factor. Table 15 shows the display times of the added fuzzy value of the physical property cluster in each feature factor and the total display times of the added fuzzy values of the entire cluster. 
         [0063]    Step  7 : The display probability (P′(F′_I n |C m )) of the added fuzzy value is obtained by using the total display times (N′_S_F_value j ) of the added fuzzy values of the entire cluster acquired in Step  6 . The relation equation is shown in equation (3-13). The Bayes probability value of each inventive principle cluster is acquired through the Bayes theorem equation. The Bayes theorem equation is expressed as equation (3-14).

         [0067]    3. Deciphering Procedures of Clustering TRIZ Deciphering Model 
         [0068]    The process for improving the deciphering ability of the TRIZ matrix is illustrated in  FIG. 5 , comprising 6 steps: 
         [0069]    In step S 51 , the design direction is determined. A user (designer) evaluates knowledge of various aspects of the design and related patent information, and determines the goal achievements of the new design direction and the related limitation conditions. 
         [0070]    In step S 52 , the improved feature clusters are selected. Coordinating with the decided new design direction, the consideration of the meanings of the  10  feature clusters is carried out. The improved feature clusters that conform to the design direction are selected to carry out system judgment. 
         [0071]    In step S 53 , the priority of inventive principle cluster is determined by the system. Entering the system interface by inputting selected improved feature cluster (as shown in Appendix 1), a menu for selecting the decided improved feature clusters is provided, such as the moving object cluster. When the analysis button is pressed, the priority order of the related inventive principle clusters is determined, as shown in the table in Appendix 2. The table shows the inventive principle cluster of the priority order. The order of the considered selections from the top to the bottom includes the inventive principle clusters which are considered suitable for the design direction and available technology. When the button of the statistical table on times and the probability table is pressed, a file in Excel format is shown (see Appendix 3). References of different models are provided for facilitating calculation of the discrimination value, helping users make a correct judgment when considering the inventive principle cluster conforming to the design direction. 
         [0072]    In step S 54 , the priority order of the no-worsening feature cluster is determined by the system. According to the inventive principle clusters selected in Step S 53 , the clusters in the interfaced table are selected, as shown in Appendix 4. The priority order of the no-worsening feature cluster is determined by the system. The order of the considered selections from the top to the bottom includes the no-worsening feature clusters which are considered suitable for the design direction and available technology. When the button of the statistical table on times and the probability table is pressed, a file in Excel format is shown (see Appendix 5). It provides users with referential values in deciding the priority order when considering the no-worsening feature cluster conforming to the design direction. 
         [0073]    In step S 55 , the general table of discrimination values of the entire inventive principle cluster and the no-worsening feature cluster is generated, just like the general table of display times of the corresponding inventive principle cluster of the moving object cluster and different no-worsening feature clusters, as shown in Appendix 6. The table of probability conversion is selected, and then the display times are converted to the form of a probability value, as shown in Appendix 7. Based on the selected no-worsening feature clusters, it is determined whether the best priority order is in the general table of discrimination values of the inventive principle cluster and the no-worsening feature cluster. During the discrimination, it is determined whether the roll is the best priority order through the vertical examination of the selected inventive principle clusters, or whether the column is the best priority order through the horizontal examination of the selected no-worsening feature clusters. After the determination, it is known whether the result conforms to the design direction, limitation conditions and technological requirements. If positive, a better no-worsening feature cluster can be decided, if negative, the steps return to Step 3 to decide the adoption of inventive principle cluster again. 
         [0074]    In step S 56 , the original TRIZ matrix is discriminated. From the selected improved feature clusters and the finally decided no-worsening feature clusters, the single improved feature and the single worsened feature that conform with the design direction and limitation conditions are selected. The original TRIZ matrix, as shown in Table 19, shows the corresponding inventive principle. Then, the preliminary idea of design can be acquired (step S 57 ). 
         [0075]    In S 57  step, the user get some inventive principle form s 56 . Then according to these ideas, engineer can judged by the ways of engineering knowledge, inference, analog, etc. So as to generator a preliminary technological idea of a design 
         [0076]    Using an automatic polishing pad changing structure of the compensating chemical mechanical wafer polishing apparatus as an example, a technological shortcoming exists, i.e., when the main polishing head having a diameter smaller than that of a wafer, and the compensating polishing head are used to undergo polishing, the polishing pad is adhered to the polishing head, and when replacing the polishing pad, the worn out old polishing pad is detached from the polishing head, the surface is cleaned, and then a new polishing pad is attached to it. During the replacement, the CMP has to be shut down for a long period of time, causing inconvenience and inefficient use of time. Therefore, the replacement of polishing pad is improved by automation of the replacement process. The design idea acquired at this time takes the designers&#39; professional experience principles as a reference. Having understood the design direction based on their experience, the designers can follow the traditional TRIZ procedures to discriminate the related suggested conditions that the improving feature is the 38th item, i.e. level of automation, the no-worsening feature is the 28th item, i.e. accuracy of measurement, and the inventive principle is the 28th item, i.e. replacement of mechanical system. After the related suggested conditions are achieved, the designers enter the TRIZ deciphering procedures constructed to carry out discrimination. It is known that the automation of the improving feature is in the control cluster of the improved feature cluster of the system. After using the control cluster, together with the improvement of the interface of the TRIZ deciphering system, a description of the procedures is made as follows: 
         [0077]    Step  1 : Having known that the improving cluster is the control cluster, the system interface is entered, as shown in Appendix 8. 
         [0078]    Step  2 : The control cluster is selected through the interface as the major considered improving cluster. The analysis button is pressed, and the priority order of the inventive principle clusters appear as shown in the table of Appendix 9. If the related numerical expressions of the priority order need to be known, the buttons of the statistical table on the number of times and the Bayes probability table are pressed. Then the Excel format as shown in Appendix 10 would appear. 
         [0079]    Step  3 : After referring to the experience principles of the researcher, it is discriminated that the adopted inventive principle is the replacement of the mechanical system. This inventive principle is in the cluster of mechanical system replacement in the inventive principle cluster of the system. Therefore, based on the priority order of the inventive principle clusters acquired by the system in Step  2 , it is observed from the table in Appendix 9 that the 2nd inventive principle cluster being considered in the first priority is the cluster of mechanical system replacement. From the referential numerical values in Appendix 10, it can be clearly seen that the referential numerical values conform to the inventive principle cluster which is considered by designers, and they are not the same values whose difference can thus be perceived. The system also considers the cluster of mechanical system replacement to carry out the judgment of the no-worsening feature cluster. 
         [0080]    Step  4 : Knowing that the cluster of mechanical system replacement is the considered inventive principle cluster, the cluster of mechanical system replacement on the table of the interface is selected to acquire the priority of the no-worsening feature clusters, as shown in the table in Appendix 11. If the related numerical expressions of the priority order would like to be known, the buttons of the statistical table on the number of times and the Bayes probability table are pressed. Then the Excel format as shown in Appendix 12 would appear. 
         [0081]    Step  5 : The general table of the entire inventive principle cluster and the no-worsening feature cluster, as shown in Appendix 13, assists in making judgment on the acquired priority of no-worsening feature clusters. After referring to the experience principles of the researcher, it is discriminated that the adopted no-worsening feature is the accuracy of measurement. This no-worsening feature is in the cluster of manufacturing and measurement accuracy in the no-worsening feature cluster of the system. Therefore, based on the priority order of the no-worsening feature clusters acquired by the system in Step  4 , it can be observed from the table in Appendix 12 that the 2nd no-worsening feature cluster being considered in the first priority is the cluster of mechanical system replacement, conforming with the consideration direction of designers. 
         [0082]    Step  6 : It is acquired from Step  3  that the inventive principle cluster is the cluster of mechanical system replacement and from Step  5  that the no-worsening feature cluster is the control cluster. Then a simplified TRIZ matrix as shown in Table 20 can be formed. By clustering, the improved feature cluster, no-worsening feature cluster and inventive principle cluster are filtered out. By using the clustering TRIZ matrix, together with the design concepts and according to level of automation of professional discrimination, the no-worsening feature as the accuracy of measurement, and the inventive principle as the replacement of mechanical system, it can be known that the improving feature, no-worsening feature and inventive principle filtered out from the clustering results are consistent with the results acquired from the traditional TRIZ procedures. For the automatic polishing pad changing structure based on this concept, the mechanical design is to cut the holding ring of polishing pad into two halves. The ring can grip the entire polishing pad and cover the edge of the polishing head, enabling the polishing pad to be firmly fixed on the polishing surface of the polishing head. The outer ring is attached with the track, which drives the machine to complete the automatic gripping action. The replacement of the entire polishing pad can be completely automated, saving mechanical work time. 
         [0083]    While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
