Key Findings

  • 01Manikin families representing obese passengers were successfully developed.
  • 02These manikins can be used to assess and improve aircraft seat dimensions for better accommodation.
  • 03The approach facilitates anthropometric accommodation of larger airline passengers.
02

Application

Design takeaway

Incorporate anthropometric data for diverse body types, including obese individuals, into the design process for enclosed spaces to ensure comfort, safety, and accessibility.

How to apply

Utilize specialized digital human models in CAD software to test the fit and ergonomics of seating and other interior components for a wider range of user body types.

Project actions

  • 01When designing products for public spaces, consider including a wider range of body sizes in your user research.
  • 02Use digital modeling tools to test how your designs accommodate different anthropometric profiles.
03

Method & Evidence

AimTo develop manikin families representing obese US airline passengers to inform aircraft seat design and improve accommodation.
MethodFactor analysis and cuboid enclosure modeling
ProcedureAnthropometric data from obese individuals was analyzed using Principal Component Analysis (PCA). For each gender, a 99% enclosure cuboid was defined, and a representative set of manikins was created based on these cuboids. Digital human models were then generated using CAD software.
ContextAeronautics and passenger accommodation design

Variables

IVAnthropometric data of obese passengers
DVAircraft seat dimensions and accommodation effectiveness
CVGender, passenger space constraints

Strengths & Limitations

Strengths

  • +Addresses an underrepresented user group in a critical design context.
  • +Utilizes quantitative anthropometric data and digital modeling for practical design recommendations.

Limitations

The manikins are digital representations and may not capture all nuances of human comfort or interaction. The specific data used might not represent all obese individuals globally.

Reliability & validity

Reliability is supported by the use of a standardized database (CAESAR) and PCA. Validity is established by the practical application of the manikins to inform design recommendations for aircraft seats.

Think critically

How might the development of manikin families for other specific user groups (e.g., elderly, disabled) further enhance the inclusivity of product design?

05

Design Principles

"Design for inclusivity by representing the full spectrum of user anthropometry in digital models."

Designers often rely on average anthropometric data, which can exclude significant portions of the population. By creating specialized digital models that represent diverse body sizes, such as those of obese passengers, designers can proactively identify and mitigate potential issues related to fit, comfort, and safety in enclosed spaces like aircraft cabins.

06

What This Means for Your Design

Researchers made computer models of people who are obese to help design airplane seats that are more comfortable and safer for them.

How to use in your project

  • 1.Reference this study when discussing the importance of anthropometric data and user diversity in your design process.
  • 2.Use the concept of developing specialized manikins to justify your own user modeling if applicable.
