A shaping pad structure was provided. The shaping pad structure includes a moldable layer, a shape retaining object, a structure of releasing mechanism, and a crystallization trigger. The moldable layer has a flexible material that allows amendable shaping. The shape retaining object is a crystallizable fluid and is in the interior of the moldable layer. The structure of releasing mechanism is put inside the moldable layer and makes contact with the shape retaining object. The crystallization trigger inside the structure of releasing mechanism can initiate the crystallization of the crystallizable fluid into solid form. The crystallization trigger is isolated inside the structure of releasing mechanism , and the structure of releasing mechanism could release the crystallization trigger into the crystallizable fluid after receiving an external effect.本案提出一種塑形墊結構,包括一塑形層,係由一軟性具可塑形之材質組成;一定形物,係由具可結晶固化之流體組成,其中所述定形物裝於所述塑形層內部;一釋物部,置於所述塑形層內部,與所述定型物接觸;以及一結晶物,可輔助所述定型物由流體結晶為固態,所述結晶物置於所述釋物部內部,其中所述釋物部接收外部作用後可釋出所述結晶物於所述定型物中。10‧‧‧塑形墊結構11‧‧‧塑形層12a‧‧‧定型物13‧‧‧釋物部14‧‧‧結晶物
