Why 'average' equipment can cause trouble (explained for an 11-year-old)
When designers make tools, chairs, desks, clothing or machines only for the "average" person, they forget that people come in many sizes, strengths, and abilities. That can cause problems. Here are 8 important problems (causes) that happen, with simple examples and easy fixes.
-
Some people don't fit the equipment
Explanation: If a chair, helmet, or glove is only made for the average size, shorter or taller people might not fit safely or comfortably.
Example: A stool is too tall for a short worker, so their feet dangle and they feel unstable.
Quick fix: Use adjustable or different-size options so everyone can fit safely.
-
More accidents and injuries
Explanation: When equipment doesn't match a person's body, they may use wrong posture or extra force, causing strains, slips, or falls.
Example: A heavy lever is designed for a very strong person, so others strain their backs trying to pull it.
Quick fix: Design controls that need less force and add safety features like handles shaped for many hand sizes.
-
People get tired faster and work slower
Explanation: Poorly fitting equipment makes tasks harder, so people use more energy and take longer to finish jobs.
Example: A keyboard is too high, so typing is awkward and slower.
Quick fix: Offer adjustable height or different setups so people can work comfortably and faster.
-
Lower morale and happiness at work
Explanation: If workers feel the tools weren’t made for them, they may feel overlooked or unimportant.
Example: Small-handed people always get gloves that are too big and feel frustrated.
Quick fix: Ask workers for feedback and provide sizes or adjustable gear for everyone.
-
Some groups are unfairly excluded
Explanation: Designing for the average can accidentally favor one group (like adult males) and make life harder for women, children doing part-time jobs, older adults, or disabled people.
Example: Machine controls placed high on a panel are hard to reach for shorter workers or wheelchair users.
Quick fix: Use inclusive design that considers lots of body types and abilities from the start.
-
More sick days and employee turnover
Explanation: If workers get injured or burned out, they might miss work or quit, which costs the company time and money.
Example: Repetitive strain from tools causes long-term pain and people stop coming to work.
Quick fix: Provide ergonomic equipment and let people choose what fits them best.
-
Safety rules can be harder to follow
Explanation: If safety gear doesn't fit most users, people might skip wearing it or use it wrong, increasing risk.
Example: A safety vest only in one size is too big and catches on machines, so workers stop wearing it.
Quick fix: Offer safety gear in multiple sizes and test it with real users before buying lots of one type.
-
Companies face legal or reputation problems
Explanation: If equipment causes harm or excludes people, companies can be fined or get bad publicity.
Example: Customers or workers complain that the workplace is unsafe or unfair because tools are not adjustable.
Quick fix: Follow rules, ask diverse people to try equipment, and choose designs that fit many users.
Short checklist for better designs:
- Make equipment adjustable (height, angle, force needed).
- Offer multiple sizes and test with different people.
- Ask workers for feedback and watch how they use the tools.
- Think about safety, comfort, and fairness from the start.
That way, workplaces are safer, happier, and work better for everyone — not just the "average."
