Optimization of product dimensions for discrete sizing applied to a tool handle

In Publications

Garneau, C. J. and Parkinson, M. B. (2012). International Journal of Industrial Ergonomics 42(1): 56-64.

The allocation of adjustability and use of discrete sizes are two methods of accounting for the variability in the population of prospective users of a product. This paper addresses the discrete sizing problem, adapting recent adjustability research. This is done in the context of the optimization of tool handle sizes, and a case study of designing multiple sizes of a nonuniform cylindrical tool handle is presented. Continue reading…

Optimization of tool handle shape for a target user population

One goal of Designing for Human Variability (DfHV) is to optimize the interaction between user and device. Often, this interaction is dictated by the spatial dimensions or shape of the artifacts with which people interact. A novel approach that applies DfHV principles including virtual fitting trials to optimize the shape of an artifact is presented and applied to the design of a tool handle. Continue reading…

Optimal product sizing through digital human models

Designing for human variability (DfHV) requires efficient allocation of sizing and adjustability. This can preserve product performance while reducing some measures of cost. For example, specifying only as much adjustability as necessary for a desired level of accommodation leads to devices which are better suited to their users and more cost efficient. Similarly, when multiple sizes of an adjustable artifact are to be produced, specifying only as many sizes as are necessary, with an appropriate amount of adjustability per size, leads to a set of products that cost less, require fewer unique parts, facilitate maintenance standardization, and ease inventory control.
