Parametric Design Method for Personalized Bras
Published in Marcelo M. Soares, Francisco Rebelo, Tareq Z. Ahram, Handbook of Usability and User Experience, 2022
“Parametric design, or parametric modeling, is a CAD technique that uses parameters or variables (numbers, length, points or curves, etc.) to rule, clarify, and encode the relationship between design intent and design response” (Jabi, 2013). Baek and Lee, in their study of parametric human body shape (Baek and Lee, 2012), utilize the parametric design method to integrate the human body shape and size into multiple applications. Other researchers, such as Wang and Shatin, also explore the parametric design methods using mannequins to study human bodies (Wang and Shatin, 2005). These cutting-edge studies provide us valuable experience on how to manipulate the body data, define the parameters and construct the relationship between design inputs and outputs. In this study, our software platform is the Rhino CAD program with Grasshopper Plug-in, which allows us to visualize the logic behind the parametric algorithm on a flowchart-styled processor, adjust the parameter values and reform the 3D models in real-time.

Grasshopper, a parametric design tool, is one of the visual programming tools used by this study. Plugged into a Rhino interface, Grasshopper can check and correct planning and design processes by parametric computing logic. The merit of Grasshopper is the ability to extract numerous parameters (including environmental information parameters, physical information, and digital information). Since there are multiple evaluation criteria for the discussion of urban issues, different design criteria can be defined through the computing of parameters, such as shelter ratios, volume ratio restriction conditions, calculation of the best route, analysis of sunshine and shadow surfaces, and horizon analysis. Parameter computing design not only inspects the design criteria that have been set but also creates a dynamic urban model through the change of parameters.
Metadesigning Customizable Houses

Developing a parametric model is in fact programming: entities are defined that form larger assemblies, relationships are established, values are assigned to parameters. Some designers do this through scripting (i.e. programming) and some use sophisticated modeling software that features visual programming. Regardless of the way in which it is done, effective parametric design requires abstractions, definitions of relationships, i.e. more than the simple knowledge of syntax of some programming or scripting language or the features of some modeling software. Once the project’s topology is articulated, the geometry can be either procedurally created (via programming scripts) or interactively modeled using some visual context for establishing associations between constituent elements of the geometry.

Parametric design refers to a representation method that allows variables that affect the shape of a mass, such as its dimensions or structures of a particular part, to be easily changed by defining them in a particular way. This representation method is used to generate an optimal form to meet complex design requirements, and since the late 1990s, formal experiments have been carried out through parametric modeling or generative capabilities of digital scripting (Dasgupta and Michalewicz 1997; Mitchell 1996; Rasheed, Hirsh, and Gelsey 1997). Parametric design methodology functions as a new toolkit in designers’ formal experiments. This allows designers to define diverse variables that determine a form and their relationships in advance and construct a design algorithm to adjust the displacement value, which leads to the production of creative variations in controlling the form in a rational manner. In its early stages, parametric design started from a purely formal approach as a way to generate a complex form in a system environment. Today, however, the scope of its usage has been expanded to address diverse issues from the visual, synesthetic, material, structural, and environmental perspectives (Schumacher 2009; Woodbury 2010).

According to Barrios (2005, p. 394), ‘parametric design is the process of designing in parametric modelling settings’. Parametric modelling, in turn, involves the representation of geometric entities along with their relationships through associated components and attributes within a hierarchical chain of dependencies. Based on this hierarchy, each of the geometric attributes is expressed through a parameter. The parameters are then split into independent and dependent parameters, where the independent parameters act as inputs to feed data to the dependent parameters that receive data and apply changes based on this data (Turrin et al., 2011). More precisely, the process enables the dependent parameters to change automatically when the independent parameters change manually, allowing an automated generation of several instances of a basic design form (Turrin et al., 2011). In this light, parametrisation is the process of defining the relations between parameters. This includes which parameters in the parametric model will be fixed, which parameters will vary, which of the variable parameters are independently variable (manually changeable), and which parameters are dependently variable (automatically changeable), together with how the variation occurs, and the range of each variation (Barrios, 2005).
