Design for Human Variability (DfHV) is the practice of designing artifacts, tasks, and environments that are robust to the variability in their users. Designs often incorporate adjustability and/or offer several sizes to account for the different requirements of the target user population. There are several situations where DfHV can provide platforming opportunities that might otherwise be overlooked. Continue reading…

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…

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.
