A leading European manufacturer of medical equipment trolleys expands into Southeast Asia. The product is mature, has won multiple awards, and is well made. Six months after launch, sales are below expectations. Distributors report: “Customers try it, compare it briefly, and move on.”
The problem: The trolley handle is optimized for users between 170 and 180 cm tall. Average body height differs significantly across these markets. Men in Vietnam, for example, average around 164 cm, compared with around 171 cm in Japan. A trolley that forces users to work with their shoulders raised or their arms in an awkward position isn't an ergonomic product. It's a physical burden.
The body-height matrix: What it means for product design

What does a 10–15 cm difference in body height mean for a medical trolley? It changes the height at which users comfortably push, pull, access equipment, read displays, and operate controls. A trolley designed around a taller user population can place handles, screens, drawers, or mounted devices too high for shorter users. What looks like a small dimensional difference on a technical drawing can become a meaningful ergonomic difference during everyday hospital use.
What trolley manufacturers need to change for Asian markets
Adapting a European medical trolley for Asian markets doesn't mean simply offering a cheaper version. It means:
- Handle height: Extend the adjustment range downward or design the handle position around a broader range of users. A fixed position based primarily on European anthropometric data can be uncomfortable for shorter users.
- More adjustment options: Fixed positions limit who can use the trolley comfortably. More finely spaced adjustment points or continuously adjustable components can accommodate a wider range of body sizes.
- Adjust the proportions: Overall height, equipment mounting positions, drawer heights, screen placement, and access to controls all affect usability. A trolley shouldn't force users to reach unnecessarily high or work in awkward postures.
- Weight: A trolley that's easy to maneuver for one user population may feel very different to another. Total weight, weight distribution, rolling resistance, and the force required to start or stop the trolley all matter.
- Wheels: Flooring conditions vary between hospitals and markets. Wheel diameter, material, rolling resistance, maneuverability, and braking behavior need to match the environments in which the trolley will actually be used.
This isn't just a trolley problem
The trolley is an example of a much broader pattern in global product development: A product is optimized for its home market and then “adapted” for international markets, with adaptation often meaning little more than translating the documentation, labels, or packaging.
MedTech and ergonomics
Medical devices, instrument handles, control panels, and operating heights designed around the anthropometrics of one user population can be ergonomically unsuitable for users with different body proportions. During long procedures or repeated daily use, poor ergonomics can increase physical strain. This isn't an anecdote. It's a medical product design issue with regulatory implications.
Vehicles and seating systems
Automakers such as Toyota and Honda have developed different seat geometries and pedal distances for their global markets. What feels comfortable for an average German driver may be too far away or too low for a Japanese driver.
Tools and handheld devices
Handle sizes on tools, grip diameters on medical devices, and keyboard widths are all calibrated around hand dimensions and ergonomic standards that often originate in the product's home market. In markets with smaller average hand sizes, including parts of Asia, that can lead to fatigue, operating errors, and lower product satisfaction.
South America: An underestimated market with its own profile
Brazil, Argentina, Colombia, and Peru share some characteristics: moderate average male heights of roughly 165–175 cm, a strong preference for functionality and durability over aesthetics, and different price sensitivities than European markets.
For product manufacturers, that means:
- Climate adaptations, including heat and humidity, can be more important than ergonomic ones
- Repairability can be a purchase criterion, unlike the European “disposable product” mindset
- Local certifications and conformity requirements need to be assessed; in Brazil, certain product categories are subject to mandatory INMETRO requirements
- Distribution structures differ, and direct imports aren't always possible
The strategic lesson for product management
International product adaptation doesn't start with translating labels or documentation. It starts with a question: What body, what habits, and what environment did we design this product for, and what needs to change for it to work just as well in another market?
The answer is almost always: more than the color or the words on the product.
Anthropometrics: Body height, hand dimensions, reach ranges, and relevant ergonomic standards in the target market
Climate: Temperature, humidity, and UV exposure. These affect materials and electronics.
Infrastructure: Electrical standards, flooring, storage conditions, and transportation networks
Regulation: Local certifications, standards, and import requirements
Cultural preferences: Color, feel, labeling, language, and sizing conventions
Pricing model: Willingness to pay, financing models, and local competitors
“A product that's the same everywhere is truly at home nowhere. The best global products feel like they were made locally.”
Thinking globally requires feeling locally. That's not a contradiction. It's a core capability in international product management and one of the most underestimated strategic skills in growing B2B companies.
