Abstract: Key of the high quality trimming innovative design is to exploit available resources within the system and super-system to redistribute useful functions, in which the difficulty is to find potential available resources. The readily-available resources of the system searched by the list of resource-attributes which is constructed, and with substance attribute as constrain, the exploit method of potential available resources based on the resource similarity is proposed. The standard solutions are reconstructed based on the function feature, and the derivation of the available resources assisted by the standard solutions which are used as knowledge source. The list of standard solutions-attributes is constructed, on the basis of second attribute similarity between standard solutions and resource attributes, introducing additional ideal resource to reconstruct available resource. On this base, the systematic method of deriving available resources with the assist of standard solutions is formed. Finally, the feasibility and effectiveness of the trimming method are verified by the example of mechanical fruit picking rod.
