How this project started?

The brief : Explore safety risks among children aged 4–6.
01PHASE 01

Identify a real safety problem through research.

02PHASE 02

Design and prototype a solution for the identified problem.

In urban playgrounds, overcrowding, poor maintenance and overlapping play patterns can increase the risk of injury. For children aged 4–6, falls, collisions and unsafe equipment are recurring concerns.

Research phase

Now how was the problem identified, let’s get into the research phase of it

I started by mapping the problem space , explored different areas of child safety, from transportation and emergency response to playground environments, before narrowing the research toward playground safety.

The problem

A fun space
can also be a risky one.

Playground injuries are a leading cause of emergency room visits among young children. In India, particularly in urban areas like Mumbai, children aged 4 to 6 are prone to injuries from falls, collisions, and improper use of playground equipment. Common injuries include minor cuts, bruises, fractures, and dislocations, many of which occur due to unsafe surfaces, equipment misuse, and poor maintenance.

Key issues identified
01

Falls from Slides

Steep slides don’t account for a child’s weight or developmental stage, causing children to drop too quickly and lose control.

02

Unsafe Surfaces

Rough, hard surfaces like concrete or gravel contribute to injuries. The lack of impact-absorbing materials increases the likelihood of cuts, bruises and fractures.

03

Inadequate Maintenance

Wear and tear often goes unnoticed, increasing the risk of injury. Lack of regular safety checks and maintenance leads to unsafe conditions.

04

Weather Conditions

Extreme weather (e.g. heat or rain) can make equipment slippery, leading to falls, burns and abrasions.

A safer playground is possible with thoughtful design.

Once it was identified that playground safety is a huge concern , it was time to build a solution while keeping in mind that a playground is a fun environment to be

Our solution

A safer playground,
for brighter tomorrows.

A design approach that combines safer equipment, smarter layouts, better materials and clear guidance — creating a fun and secure environment for children aged 4–6.

1

Modular Design

Adjustable, age-appropriate equipment based on age, weight and physical abilities for a safer play experience.

Adjustable heights
2

Impact-Absorbing Flooring

Use rubber mulch, synthetic turf or padded tiles to create softer landing zones, especially around high-risk equipment.

3

Safer Play Zones

Separate zones for high-energy (e.g. swings, slides) and low-energy activities (e.g. sandboxes) to reduce overcrowding and accidents.

4

Education & Signage

Clear, engaging signage to educate children and caregivers about safe play behaviours, with visual cues and simple warnings.

Simple and fun messages
5

Supervision-Friendly Layout

Open sightlines and designated seating areas for caregivers ensure better supervision and safer play environment.

The solution

How the solution works

A zone-based playground design that uses colour, space and movement to create a safer and more intuitive play experience for children aged 4–6.

Top view of the scale model with labelled zones N · Top view (Scale model)
Zone designation

Red Zone

High-risk areas around swings, slides, and merry-go-rounds. Injury prone areas.

Yellow Zone

Moderate-risk transition areas between high and low risk.

Blue Zone

Low-risk areas for free play or resting.

Trails

Durable, bicolor trails guide children safely between zones, acting as playful signage.

Spatial layout

Sufficient spacing between equipment to reduce overcrowding, with clear sightlines for supervision.

Engagement & education

Playful and child-friendly colours teach children about zones and trails in a simple, fun way.

Behavioral insights

Design zones and trails to align with natural play patterns while guiding safe movement.

Process

Glimpse of the process

A scaled architectural model (1:32) of the redesigned playground was created, supported by CAD designs and 3D-printed elements. The model incorporated laser-cut elements to reflect real-world measurements.

Feedback

Feedback received:

The children will definitely look at the trails and follow
them so this will avoid collision

Trails
SPEED

The color coded zone is simple
but can turn out to be effective as children may psychologically start slowing down as they see the color red

Colour coded zones

Include activities that require:

  • Two children to activate something together
  • Taking turns
  • Racing
  • Following one another
  • Building something collectively
  • Pretend play
Play together
Way forwards/future prospects :
