Patent ID: 7328142

Claim:
A design method for designing a vehicular lamp, comprising: a standard data selection step for generating lamp design data by selecting one piece of standard data from a plurality of standard data registered in a standard database based on design conditions including a performance condition required for the vehicular lamp and a restriction condition given for the lamp, wherein the plurality of standard data is utilizable as source data of the lamp design data used for lamp designing, the standard data being prepared, respectively, in a predetermined uniform data format having at least constitution data about a constitution of the lamp, and wherein the restriction condition includes a shape restriction condition and an appearance restriction condition; and a morphing step for preparing lamp data satisfying the design conditions by updating a necessary part of the lamp design data based on the design conditions, and storing the updated lamp design data in a computer-readable storage unit, said morphing step including a shape design step of updating shape data in the lamp design data by obtaining a shape template from a technology database for use as the shape data, the shape template being prepared so as to correspond to the data format of the standard data and having a shape parameter for deformation, and setting a value of the shape parameter to update the shape data.
