Good Design. One hundred years of responsible design (with a bit of psychology in the background)
When we furnish an apartment today, choose a crib, a lamp, or a desk for our child, we think about aesthetics, quality, and trends. We rarely realize that behind rounded edges, a calm color palette, or a soft-close system lie a hundred years of psychological, sociological, and accident analysis research.
Good product design is no accident. It has evolved from mere decoration to a responsibility.
From ornament to function: When design was given a task
The founding of the Bauhaus in 1919 is considered the symbolic beginning of the modern understanding of design. The modernists believed that form should arise from function and that an object should serve people instead of impressing them with superfluous ornamentation.
Designers of that era were convinced that well-designed homes—bright, structured, and functional—could positively influence family life, health, and even social relationships. From the outset, design had a social dimension. It was no longer understood merely as a creative discipline, but as a responsibility.
Psychology changes design.
The real turning point came when developmental psychology was incorporated into the design.
Jean Piaget showed that children are not "little adults." They think concretely, react impulsively, and can only foresee consequences to a limited extent. This was a key insight for design.
Children react more quickly to color and contrast than to text. They explore the world through movement and touch. They do not analyze risks rationally.
The perceptual psychologist James J. Gibson coined the term affordance – that is, the action possibilities that an object conveys through its form. If something looks like a handle, it will be pulled. If something looks like a step, it will be climbed. Children react particularly directly to such visual signals.
Therefore, contemporary design rounds off edges, avoids small, detachable parts, uses contrasts to highlight differences in level, and reduces shapes that could provoke risky behavior. This is not a passing fad, but a consequence of our understanding of how the brain works.
Accidents as a turning point
Research into childhood accidents increased significantly in the 1960s and 1970s. Reports from the World Health Organization showed that accidents were among the most common causes of death in children.
This changed the perspective. Instead of asking why a child was careless, the focus shifted to analyzing context and product design. This led to the principle of "Safety by Design," where safety is considered as early as the concept phase.
In practice, this meant the development of fault-tolerant solutions: more stable furniture constructions, mechanisms to prevent pinched fingers, pollutant-free materials, and seat belts as mandatory equipment in cars. User error was no longer considered an individual failing, but rather a component of a system that had to be taken into account.
A good product forgives mistakes.
At the end of the 20th century , Donald Norman coined the concept of human-centered design. His thesis was clear: if users repeatedly make mistakes, the problem usually lies in the design.
This way of thinking also influenced products for children. Soft-close mechanisms, safety locks, tip-proof designs, and non-toxic materials became standard.
Design began not to punish mistakes, but to minimize their consequences.
Spaces influence emotions
Environmental psychology shows that spaces influence stress, concentration, and behavior. Sensory overload increases arousal and impulsiveness—especially in children whose nervous systems are still developing. Clear structures and natural light, on the other hand, have a regulating effect.
Therefore, contemporary children's and family rooms increasingly rely on calm color schemes, natural materials and visual order.
The social context also plays a role. Jane Jacobs showed that safety increases where spaces are visible and lively. Playgrounds in the center of a residential area, semi-public courtyards, or traffic-calmed zones promote natural social control and strengthen the sense of community.
Security and autonomy in balance
Current developmental psychology research indicates that completely eliminating risk is not beneficial. Children learn to assess dangers through experience. They need challenges – but controlled ones.
Modern design therefore seeks balance. Structures are stable, surfaces cushion falls, and heights are age-appropriate. Protection does not mean preventing exploration.
