Commercial vehicle seats designed for populations in manufacturing countries do not fit Nigerian drivers, leading to ergonomic risks. This human factors research insight is drawn from a 2023 study published in International Journal of Scientific Research and Management (IJSRM). Using Quantitative observational study with 161 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must research and apply anthropometric data specific to their target user population, rather than relying on generic or foreign data, to ensure product suitability and user well-being.

Key Findings

  • 01Average sitting height (erect) was 83.01 cm, sitting height (normal) was 77.86 cm, shoulder height was 52.71 cm, buttock-knee length was 57.07 cm, and buttock-popliteal length was 50.20 cm.
  • 02A significant mismatch was found between the drivers' anthropometric measurements and the dimensions of the vehicle seats.
  • 03Existing commercial vehicle seats are not compatible with the anthropometric dimensions of the drivers in the Southwest region.

Application

Design takeaway

Designers must research and apply anthropometric data specific to their target user population, rather than relying on generic or foreign data, to ensure product suitability and user well-being.

How to apply

When designing any product that involves physical interaction, such as furniture, tools, or vehicles, use anthropometric data relevant to the intended users' geographical location and demographic.

Project actions

  • 01If designing a product for a specific user group, find out their average body measurements (anthropometry).
  • 02Consider how different body sizes might affect the usability and comfort of your design.

Method & Evidence

AimTo determine the extent of mismatch between the anthropometric measurements of occupational drivers in Southwest Nigeria and the design parameters of vehicle seats in commercial vehicles.
MethodQuantitative observational study
Procedure1. Randomly selected 161 male drivers. 2. Collected anthropometric data (sitting height, shoulder height, buttock-knee length, buttock-popliteal length) using a stadiometer and measuring tape. 3. Measured vehicle seat design variables (seat dimensions) using a tape rule and steel rule. 4. Statistically analyzed anthropometric data to calculate means, standard deviations, and percentiles (5th, 50th, 95th). 5. Compared driver anthropometric measurements with vehicle seat dimensions.
Sample161 participants
ContextCommercial vehicle drivers in Southwest Nigeria

IVAnthropometric measurements of drivers, Vehicle seat design parameters
DVMismatch between anthropometric measurements and seat design parameters

Strengths & Limitations

Strengths

  • +Uses statistical analysis to quantify anthropometric data.
  • +Directly compares user measurements with product specifications.

Limitations

Your own anthropometric study might have a small sample size or be limited to a specific demographic, affecting generalizability.

Reliability & validity

The study's reliability is supported by the use of standard measurement tools and statistical analysis. Validity is strong as it directly compares user measurements to product specifications within a defined context. However, generalizability may be limited by the specific sample and region.

Think critically

What are the ethical implications of designing products for a global market without considering local anthropometric variations?

05

Design Principles

"Design for the user's specific anthropometric characteristics."

This highlights a critical failure in applying anthropometric data to product design, directly impacting user comfort, health, and safety. Designers must consider the specific user population and their anthropometric variations when designing products for diverse global markets.

06

What This Means for Your Design

Car seats in Nigeria are too small for the people who drive there because they were designed for people in other countries.

How to use in your project

  • 1.Use this study to justify the need for anthropometric research for your target user group in your Design Brief.
  • 2.Cite this study when discussing the importance of user research and anthropometric data in your Evaluation section.

Paragraph starter

The study by Onawumi et al. (2023) highlights a critical issue in product design where a mismatch between user anthropometry and product dimensions can lead to ergonomic risks. Their research on Nigerian drivers revealed that vehicle seats designed for foreign populations did not accommodate the local drivers' physical characteristics, resulting in incompatibility and potential musculoskeletal disorders. This underscores the necessity for designers to conduct thorough anthropometric research specific to their target user group and geographical context to ensure product suitability, comfort, and safety.
