Purpose-Oriented Modelling of the Learning Process When Using Prototypes

Abstract

Prototypes are often used as a tool in the product development process and their usage is advised in many guidelines, frameworks and product development methods. Those prototypes achieve different goals of which most relate to getting new insights and information about the product in development. For the development of those prototypes however, significantly less development methods are available compared to the number of methods for the development of products. Investigating the process of using a prototype leads to the idea that the main purpose of those prototypes is describable as learning about the product. This idea is elaborated further and followed by the introduction of the detailed process model for prototyping which is primarily based on the detailed process model for products. However, the purpose of the prototype differs from the purpose of the product which leads to some significant changes of the model. To give an example of a prototyping process, the development of a sensor- integrating elastic claw coupling is introduced and analysed. In addition, this paper discusses the question, how other product development models may be applied to the development of prototypes.

A Review on Sensor‐Integrating Machine Elements

“…Schork et al [178] proposed two concepts for sensor-integrating not shiftable, flexible, interlocking couplings: i) a helical beam coupling for the measurement of shaft misalignments and ii) a concept for an elastic jaw coupling. The advantage of the helical beam coupling for sensor integration is the fact that it has a relatively large installation space for the electronics due to the cavity, which is even partially capsuled.…”

“…By applying strain gauges on the plate the deformation can be measured. Schork et al [178] found that angular displacement can be reliably measured, whereas radial displacement can only be determined inadequately. For the elastic jaw coupling, they integrated a bending plate, with applied strain gauges in one tooth of the gear rim, in order to measure the deformation of the tooth.…”

“…In addition, the process of prototyping serves as a valuable tool for assessing the potential manufacturability and production feasibility of a given physical product [49]. The development of prototypes that bear a strong resemblance to the ultimate product enables teams to evaluate a range of factors, including material compatibility, assembly processes, and cost considerations [50]. The prompt detection of manufacturing limitations or obstacles confers upon teams the ability to effectuate requisite design adjustments, thereby guaranteeing a seamless progression from prototype to production.…”
