<jats:p>In the search for sustainable products idea, Bio-mimicry is one of the method to find alternative solutions. Bio mimicry is a method to define solution that is filtered and developed by nature. This study used bio mimicry technology to formulate a model of “hand swimming aids” to increase hands thrust in the water when swimming. The proposed model is based on the use of the Bio mimicry Design Spiral rule. Spiral Bio mimicry Design Rules used to simulate the shape and functional design of selected natural organisms. This study learn how frog lining model help frog to swim and select one model and apply it on hand swimmer tool design so that it can produce more sustainable products and can apply the design function of natural model well.</jats:p>
