Our talk with CHAYMA

3 March 2021

"As a mechanical engineer, I have to intervene in solutions and research"

Congratulations to the winner of the HeroesToo Design Challenge 2020-21, Chayma Bedoui!

Last week we had the opportunity to sit down and talk to Chayma about her participation in the challenge, the inspiration of her idea and much more!

Chayma plans to use the challenge's grand prize, a 3D printer, to set up a 3D print-club for children in her local area!

A special thank you to our sponsors @GrabCad @stratasys @steelcase & @makerbot for their support of the challenge

Collective action helps to solve larger issues! Let's work together! We can all be HeroesToo!

6 Finalists

18 February 2021

Study Shield

This design & product would allow for students and teachers to work in close proximity to each other, while transparent polypropylene sheets would keep each other safe! 

Social Distancing Bench / Chair

This furniture would allow social distancing and sanitisation, while being able to move into several configurations! 

Social Distancing Watch

This watch would maintain social distancing in enclosed environment by measuring the distance via Bluetooth and alerting the users if they're too close! 

Umbrella Frock

This frock already measures the social distancing requirements when worn! 

The compact Queue

This would reduce the length of the existing queue, maintain spacing & act as a protective barrier between people. Simultaneously, people may rest while waiting and communicate securely! 

Lounge Sofa

This sofa maintains distance while being able to communicate with others as normal! 

We are truly thankful for all your hardwork!  We can all be HeroesToo 

HeroesToo presents

Design Challenge 2020-21:

Creative ideas in a pandemic

Putting your imaginative spirit to the test, HeroesToo Design Challenge 2020-21 aims to promote creative thinking and problem-solving capabilities among the student community, while addressing social and environmental issues.


The challenge is open to teams from primary and secondary schools in Hong Kong and abroad. The teams will have to develop innovative and sustainable solutions for social distancing issues while retaining the essence of ‘pre-social distancing’ normalcy.


Details of Design Challenge 2020-21


The competition is looking for a design that can act as a physical barrier, serving the purpose of social distancing, while

maintaining the dynamics (i.e. form of communication, lunchtime set up, fluid exchange of ideas etc.) of the original

learning environment.


Create a sustainable design idea that makes your school life normal again, while keeping the social distance guidelines in place.


  1. It should, for example, allow you to: spend your lunchtime with your classmates, eating, laughing or playing; have team competitions like sports or musical events; have normal social interactions with your classmates and teachers

  2. A design that can eventually be manufacture and distributed on a large scale by our partners, helping to address the issue of social distancing in a sustainable way

  3. A design that is beyond what is available in the market right now

Imagine you win, hundreds of thousands of people will be using your invention?! 

Let’s put our thinking caps on and get this problem solved!
