Universal design (German: Design für Alle; in the European standards context also called design for all) is the design approach of laying out a product from the outset so that as many people as possible can use it without adaptation, including people with limited strength, mobility, vision, or hearing.
From special solutions to basic design
The approach differs from assistive special solutions: Instead of adapting a standard product afterwards, the range of abilities is built into the design from the start.
The practical benefit usually extends beyond the target group. A closure that opens with little force also helps the nurse under time pressure. High-contrast labeling also helps in poor light.
Particular importance in medical technology
In medical technology, the user group is often restricted by definition: Users are ill, undergoing treatment, weakened, or older. What is an edge case in other industries is the normal case here.
This is especially evident for products intended for home use. There, nobody operates the product with training and routine; the patient or a family member does. The representative users are then exactly those people whose abilities vary the most.
Typical weaknesses in practice
- Accessibility as a retrofit. The requirements are examined only once the design is settled. Then only a special solution remains.
- User group defined too narrowly. The use specification describes the experienced, healthy user, although the actual users are ill, weakened, or older.
- Tests without users with limitations. The sample lacks people with limited strength, mobility, vision, or hearing.
- Only the screen considered. Accessibility is applied to the software. Packaging, labeling, and instructions for use are left out.
Standards and rules
At the European level, EN 17161 (2019 edition) describes the design-for-all approach as a management task. The standard treats design for all, universal design, accessible design, and inclusive design as terms with similar meaning. For digital products, EN 301 549 specifies the accessibility requirements in concrete terms. It was newly published in September 2026 in version V4.1.1 and adopts WCAG 2.2; the Official Journal of the EU still cites version V3.2.1 (as of September 2026). The rules are thus in motion.
Universal design lays out a product from the start for the full range of human abilities instead of adapting a standard product afterwards. In medical technology, this is the normal case and not a marginal topic: Users are often ill, weakened, or older, especially for products intended for home use.
Frequently asked questions (FAQ)
What distinguishes universal design from accessibility?
Accessibility usually describes a requirement that a product must meet. Universal design describes the design approach of considering that requirement from the start instead of retrofitting a special solution. In effect, the two overlap strongly.
Why is the approach particularly important in medical technology?
Because users there are often ill, weakened, or older. What is an edge case in other industries is the normal case in medical technology. Especially for products intended for home use, nobody operates the product with training and routine.
Which standards are relevant?
EN 17161 describes design for all as a management task, and EN 301 549 specifies accessibility requirements for digital products and was newly published in September 2026 in version V4.1.1.
Is design for all the same as universal design?
Largely, yes. EN 17161 treats design for all, universal design, accessible design, and inclusive design as terms with similar meaning, and ISO/IEC Guide 71 notes that they are often used synonymously.
