A Demonstration of Potential Role of Golden Ratio in Product Design Applications

Abstract

The product design related evolutionary transformations are strongly linked to the different geometrical dimensions. The natural process of evolution of life forms on Earth provides a blueprint for improvements in design dimensions of products. It took thousands and thousands of years for various biological varieties of plants and animals to evolve into their current form through the process of natural selection. During this long transition period, many biological species have developed a variety of geometrical shapes, inside and outside their bodies. However, there are certain geometrical patterns, which occur more repeatedly in the living creatures like plants and animals. The repeated appearance of golden ratio in a lot of life forms is evidence of its recognition by nature, in the process of evolution. The present work derives the motivation from occurrences of such mathematically defined graphics, especially the golden ratio. As an investigation, a simulation of crane hook has been created under the static stress. Two 3D models of hook have been created using Solidworks design software. One model is prepared as per the standard pre-existing proportions, and another being designed using the “golden ratio-based geometry.” Both models have been tested for “Maximum von mises stress,” under the application of same level of external pressures and forces. Stress distribution pattern in two designs were observed and compared for examining any possible significance of direct utilization of golden ratio in this product design application.
