Industrial trolleys designed without considering worker anthropometry, specifically handle height, lead to increased discomfort and musculoskeletal disorders. This human factors research insight is drawn from a 2019 study published in American Journal of Industrial and Business Management. Using Comparative analysis and statistical testing with 50 workers, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must prioritize user anthropometry, particularly for adjustable or critical dimensions like handle height, to prevent musculoskeletal disorders and enhance user comfort and efficiency.

Key Findings
- 01A mismatch exists between worker anthropometry and industrial trolley dimensions.
- 02Short wheel radius and handle height were identified as key issues causing worker discomfort.
- 03Workers reported pain in various body parts due to non-ergonomic trolley design.
Application
Design takeaway
Designers must prioritize user anthropometry, particularly for adjustable or critical dimensions like handle height, to prevent musculoskeletal disorders and enhance user comfort and efficiency.
How to apply
When designing any equipment that requires manual interaction, collect relevant anthropometric data from the target user group and ensure key dimensions (like handle height, grip diameter, reach) are within the optimal range.
Project actions
- 01When designing a product for a specific user group, gather anthropometric data relevant to that group.
- 02Consider how different body sizes will interact with your design and identify potential ergonomic issues.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Directly addresses a real-world problem in industrial settings.
- +Combines physical measurements with user feedback.
Limitations
My study might only consider a narrow range of user body types or specific trolley models. The subjective nature of reported pain can also be a limitation.
Reliability & validity
The study's reliability could be enhanced by using standardized anthropometric measurement tools and protocols. Validity is supported by correlating physical measurements with reported user pain.
Think critically
How might the findings change if the study included workers of significantly different ages or genders, or if the trolleys were designed for different types of industrial environments?
Design Principles
"Design for the user's physical dimensions to ensure comfort, safety, and efficiency."
This highlights the critical link between product design and user well-being in industrial settings. Ignoring human factors can result in significant health issues for workers and reduced operational efficiency.
What This Means for Your Design
If you design a tool or piece of equipment without thinking about the size of the people who will use it, they might get hurt or find it really uncomfortable to use.
How to use in your project
- 1.Use anthropometric data to justify design choices for dimensions like handle height, button placement, or seat dimensions.
- 2.Refer to this study when discussing the negative impacts of non-ergonomic design on user health and productivity.

Paragraph starter
The study by Talapatra et al. (2019) highlights the critical impact of industrial trolley design on worker musculoskeletal disorders. By failing to align trolley dimensions, such as handle height and wheel radius, with worker anthropometry, significant discomfort and pain were reported. This underscores the necessity for designers to integrate comprehensive anthropometric data to ensure user comfort, safety, and operational efficiency in manual handling equipment.
