Advances in all areas of knowledge have increased the average and quality of life of the current society, many of the resources involved in maintaining our global quality of life are finite and certain regions of the world have greater benefits than others, in the current context the human being suffers from different global problems such as:


-Natural catastrophes.

-Pollution of the environment.


-Social insecurity.


These global problems are constant and the number of victims are increasing exponentially while the number of habitants in our planet increases, In most cases there is a common factor which we will take as a problem to solve in our idea:

"The sudden loss of homes"

Since 2003, more than 67 million people had to leave their homes due to some of the causes mentioned above, in more developed countries there are protocols and areas destined to serve as shelters in case of emergency (in many cases they are not enough), but in less developed countries there is no solution or plan to accommodate the victims of an emergency, so we focus on developing a product that can meet this need, a safe, livable, easy to transport, reusable and economical shelter.

In the market there are many shelter solutions for emergencies, most are focused on practicality and economy (tents and awnings). We believe that people who go through an emergency that forces them to leave their homes need a decent temporary space. A refuge that brings them:

-Thermal isolation

-Acoustic isolation



We designed CAVE, a shelter that gives victims a space of privacy and tranquility, which allows them to overcome emergencies in the best conditions.

The walls are manufactured with recycled EVA by NIKE GRIND, they isolate temperature and acoustics, it is also designed in modules, which can be interconnected to adapt to each type of family or community. Because emergencies are unpredictable CAVE is designed so that each region has a batch of shelters ready for an emergency.


In the history of man there are several technological leaps, they represent the foundations of our global society and all the technology that grows rapidly.

We do not have the data of when but it is known that one of the most important jumps occurs when the man stops being nomadic and becomes sedentary, when he manages to gather all the necessary elements to survive in a single geographical region, without the need to move constantly. 

One of the factors that catalyzed this breakthrough was to start living in caverns, natural caves that are in the mountains, these gave to primitive man the necessary protection to avoid being cold and get sick in winters, not get wet in storms or be eaten by nocturnal predators.

When a man begins to inhabit caves, his quality of life increases considerably and the population begins to grow, which in turn forces him to become a social being, and through gestures and sounds the species begins to create a language to communicate ideas.

The main characteristics of a refuge are:

-Protection of natural elements.
-Protection of predators.
-Living temperature.
-Ability to store food or objects.

Which Nike Grind materials will your idea utilize?

  • EVA Foam Injection Scraps
  • EVA Foam Flashings
  • EVA Foam Sheets & Blocks
  • EVA Foam Components
  • Laminated EVA Foam

How specifically will these materials be incorporated into your solution?

The system is composed mainly of two elements: 1-The Ublock The Ublock have two functions, gives the necessary mechanical stability to the structure and isolates the living area. It is made of two materials: aluminum on the ends so that each piece is durable and the tension does not deform the geometry with the passage of time, and Eva of NIKE GRIND mixed with a polyester binder, later compacted in a hydraulic press of 10 tons with a mold that gives him the geometry. 2-The tie-down Tensioner that works for the assembly of the system, is a product that already exists in the market, and its use is very common in many activities.

Please include a visual (can be either 2D or 3D) representation/prototype of your concept. (required)

What is the current stage of development of your idea?

  • Research & Early Testing

Describe your target market. Who will benefit from your product?

More than 67 million people have left their own home because of a humanitarian crisis since 2003.

How will you scale your idea? Please describe in detail your plan to scale your concept.

We are proposing a universal refuge, which is a functional solution for any emergency, in any part of the world, therefore, the potential of this product is that each community has a lot of shelters as a precaution.

How is your idea innovative?

CAVE is a shelter designed to respond in an emergency, allowing the displacement of a large number of shelters immediately. In addition, the walls of CAVE made of EVA allow thermal and acoustic isolation, which increases the quality of life of victims who habit it in an emergency, helping to face emergencies in better conditions.

What inspired this idea?

We want to provide a quick living space when there is an emergency, to make families recovery easier.

Tell us about yourself and your team. What is your background and experience?

Luca Ruiz / Industrial Designer Efren Caraveo / Architect

In what city are you located?

Puerto Vallarta & Guadalajara

In what country are you located?


Please describe how becoming a Top Idea will support the growth of your concept.

We have the tools and the team to make this possible, we only need the push.

I like the idea of CAVE as a solution to humanitarian crisis for so many people around the work who at some point will need emergency shelter. Sad thing is the number keeps growing. I would agree that this is an innovative and practical solution.

Hi Dahalia, thank you for your comment, we agree with you, CAVE is designed to respond immediately to a humanitarian crisis, we seek to give a comfortable space to the people affected, the system is designed to meet two main functions:
-Storage and transportation: this shelter is like a life jacket in a community, it will always be folded and stored in some warehouse in case an emergency arises, it is easy to transport if you have to send the shelters to a neighboring community as support.
-Robust, durable and isolate: It must provide the greatest comfort to people who use it, providing privacy, a comfortable temperature, protection from the weather, and a quiet space to sleep.
This system is definitely not a solution to avoid a humanitarian crisis, but it is a tool for the positive recovery of communities.
