Application

Design takeaway

Incorporate tolerance analysis as an integral part of the conceptual design process, rather than treating it as a separate, later stage.

How to apply

Develop or adopt a modelling framework that allows for the simultaneous representation of design intent and tolerance specifications from the earliest stages of concept development.

Project actions

Method & Evidence

AimHow can a unified conceptual model combining graph-based tolerancing and the Contact and Channel approach facilitate the integration of tolerancing into conceptual design for enhanced robustness?
MethodConceptual modelling and case study application.
ProcedureThe study proposes a conceptual model that merges two distinct approaches: graph-based tolerancing and the Contact and Channel approach. This combined model was then applied to a specific design problem, a coinage machine, to demonstrate its utility in evaluating the robustness of design concepts.
ContextProduct design and engineering, specifically focusing on conceptual design and tolerancing.

Variables

IVIntegration of graph-based tolerancing and Contact and Channel approach into conceptual modelling.
DVRobustness of the design concept.
CVSpecific product being modelled (e.g., coinage machine), functional requirements.

Strengths & Limitations

Strengths

  • +Provides a novel conceptual framework for integrating two key design domains.
  • +Demonstrates practical application through a case study.

Limitations

The complexity of the chosen modelling approach might be challenging to implement fully within the scope of a typical design project.

Reliability & validity

The validity of the model's findings is supported by its application in a case study, though further validation across diverse product types would enhance its generalizability. Reliability would depend on the consistency of application by different design teams.

Think critically

To what extent can a purely conceptual model truly capture the complexities of real-world manufacturing tolerances, and what are the trade-offs between model simplicity and predictive accuracy?

05

Design Principles

"Robustness is achieved through the early and integrated consideration of variability and its impact on function."

Early integration of tolerancing principles into the conceptual design process is crucial for achieving robust designs. This approach allows for the identification and mitigation of potential issues related to manufacturing variability before significant design commitments are made, ultimately reducing costly revisions later in the development cycle.

What This Means for Your Design

Think about how parts will fit together and how small manufacturing errors might affect how something works *while you are still sketching ideas*, not just when you are figuring out the exact measurements.

Paragraph starter

The integration of tolerancing considerations into the conceptual design phase, as proposed by Grauberger et al. (2020), is essential for achieving robust designs. By employing unified conceptual models that link design intent with potential manufacturing variations early on, designers can proactively identify and mitigate risks, leading to more reliable and cost-effective product development.
