Claim One:
1. A method for constructing one or more golf clubs comprising the steps of: a. capturing input data measuring values for a plurality of input parameters corresponding to a golfer's performance needs, the plurality of input parameters comprising club head speed, ball speed, launch angle, backspin, spin rate, effective loft, face angle, and the normal and tangential components of the force vector; b. drawing inferences about golf club design parameters from said plurality of input parameters, where the inferences are made by a processor programmed to use a fuzzy logic algorithm comprising the steps of: i. providing one or more membership functions to transform input data into antecedent variables belonging to fuzzy sets; ii. applying fuzzy rules to the fuzzy sets by steps comprising: 1. assigning a relative weight to each antecedent variable; 2. applying a logical operator between the different antecedent variables of each rule; 3. implying the consequent variable for each rule; 4. aggregating all consequent variables; and 5. wherein the fuzzy rule is either a single-input-single-output rule, a multiple-input-single-output rule, or a multiple-input-multiple-output rule, and iii. defuzzifying the consequent variables into crisp variables; c. developing one or more computer models based on the inferences about one or more golf club design parameters; and d. operating a machine configured to fabricate one or more golf club heads according to the one or more computer models.
