How to prevent children dying from vehicular heatstroke?

Why we chose the idea? Why it is innovative?

According to, 774 children have died due to vehicular heatstroke since 1998 in the US alone, and the number keeps rising. 74% of the children are younger than two years old. Therefore, reminding parents not to forget their children in the hot car can prevent irreversible damage and deadly tragedies. 

With the intention of finding a solution, we searched the web and found that Mercedes Benz cars have solved this problem by adding sensors in the car, and alerting the parents accordingly. However, not every family can afford this luxury car. Thus, there is a market for a product that is easy to use, cheap and efficient. We took advantage of smartphones and that every child sits in a baby car seat, to develop a built-in feature in the baby seat accompanied with an app as a solution for the problem.

A simple and innovative solution does not exist in the market, and since we are passionate about the problem, we choose to tackle this ourselves.


Can you figure out a solution and design a product to prevent future kids from losing their lives in vehicular heatstroke? Consider as many situations as you can that may cause pediatric vehicular heat stroke accidents, make it easy to use and avoid over-alarming.


  1. Divide into groups to discuss how dangerous pediatric vehicular heat stroke is, and why do you think it occurred.
  2. Search for the past research about vehicular heatstroke from the Internet. You can read this article published by Stanford University as a starting point.
  3. Work out a solution to prevent future tragedies and how to do it innovatively;
  4. Present your solution with a presentation or video.


Requirement of the product:

  1. Applicable, user-friendly
  2. Thoughtful, consider as many situations as possible
  3. Affordable for customers




Explaining the danger of vehicular heat stroke



Collecting data from the internet and search for existing products that try to prevent children’s heat stroke



Solution to deal with children’s heat stroke.



Presenting the solution, which needs to be logical, innovative and applicable.



Teamwork: work allocation between teammates.



Learning outcomes:

By completing this assignment, students will develop the abilities to communicate, collaborate, collect and process data, and ICT literacy:

  1. To convey their ideas to others and accept others’ opinions, students must acquire communication skills such as writing, speaking, listening and networking.
  2. To work in groups, students will develop collaboration skills including teamwork and accepting others’ opinions.
  3. To search the Internet and work out a solution, students will develop data collecting and processing skills like retrieval, assessing information source, and analyzing.
  4. To present their ideas, students will develop ICT literacy.

These are the expected outcomes of this assignment.



According to the assignment, we formed a 5-person group; we went through the information about vehicle heatstroke and decided to produce a baby car seat accompanied with an app, and we named it "Don’t forget Me".

The special aspect about this baby seat is that it has a built-in weight sensor, heat sensor and distance sensor. The weight sensor detects if there is baby in the car seat, the heat sensor measures the temperature of the car and the distance sensor measures the distance between the parent's phone and the car seat.

As a result, when the distance sensor detects that the parent exceeds certain length, and the weight sensor detects that the baby is still in the car, an alarming notification will remind the parent to get the baby.

In addition, when the temperature of the car gets dangerous, a notification will also be sent to the parent's phone.

Thus, the parent won't leave their babies in unwanted conditions and lives are saved. The product is easy to use, avoids over-alarming and meets the requirements of the assignment.

Dear Group #5,

First, it was a pleasure reading your PBL, and have the brainstorming.

I think the PBL is well-defined. For further elaboration, on specific theme, we learned that parents do not invest in such devices eventhough they are lifesaving. The rationale might be, of the parents incapable of overcoming the obstacle of "admitting" that they might accidentlly forget their loved ones in a car.

Perhaps, a key requirement on the PBL should be addressing these critical point, and asking the students to implement a low-singature solution, that would not require an initiative from the parents side.

I am impressed by your clear layout of the PBL instruction and the sample. However, as our team has discussed, parents may be reluctant to purchase the product since they hardly think they would ignore their kids in the back seat. Another possibility is that parents have already made great efforts in the car seats. The market size would be small as a consequence.

To further improve your product/idea and make it more persuasive, I highly recommend you to read the articles that tell the stories of other dangers in and around the vehicle that could seriously harm or even kill the child below:

As been stated in the articles/website, cars and car seats have been researched and inspected carefully. If you can refine your idea with the above concerns being taken into consideration, it would be much more convincing in the real market.

I'm so impressed with this PBL design. What impressed me most includes:

1. Clear description of task.

A brief and vivid video is provided so that participants can easily understand the project. 

2. Proper selection of the question.

Kids' heatstroke is such a popular question around the world, while seldom high-quality solutions have been provided. Solving this problem requires knowledge and experience in many disciplines, and in this way, it can stimulate innovation.

3. Brief but data-based background infomation.

 The background introdution is data-based and convincing, which easily raise attention of participants.

4. Detailed and friendly guides

Detailed guidelines make the course friendly to students.


I think the following part could be improved if more time permitted:


A more detailed assessment form could be deisgned for participants, with detailed criteria that can measure how they perform and collaborate with each other.


Overall this PBL design is still very impressive for me.

I like this PBL assignment, especiall for its clear guidelines. 

I believe the clear guidelines can be very helpful for students who join in PBL at first time. And It is a good way to ensure the quality of PBL.

One thing I suggest to do is to show the criteria of assessment more clearly. In this assignment, I see the assessment includes 5 parts, but I have no idea about how each part will be assessed.

In our assignment, we have two kinds of criteria. One is for self-assessment part, and the other is for peer-assessment part. In the former part, we present some specific questions about the market and competitiors' products. In the latter part, we ask some questions about the skills and techniques students use or learn in the process of PBL, as well as the contribution and involvement. (Refer to our assignment:
