Chinese pepper picking tool designs and evaluations based on the TRIZ theory and the triangular fuzzy number

Abstract

Farmers are prone to be scratched when they are picking Chinese peppers by hands because of the thorns. Therefore, the safe and effective picking tools are extremely significant for the workers. But there is no one Chinese pepper picking tool that is really suitable for farmers. In this paper, four Sichuan pepper picking tool schemes are designed based on the TRIZ theory and they are evaluated by the triangular fuzzy number complementary judgment matrix. The evaluation indexes are marked by four raters. Calculating utility value and then we select the best scheme. And this paper may provide an evaluation method for the other product Designs.
