  • Yes

Date Started


Project Stage: Select the description below that best applies to your approach.

  • Idea (hoping to get started in the future)

1. Personal Journey: What’s the story behind why you decided to start this project? NOTE: All applications must include a 1 minute video that answers: “I am stepping up to make change because..."

VIDEO COMING SOON! After seeing all of the incidences of these poor innocent children becoming injured or even losing their lives because of forgetful, careless or just outright negligent parents, I knew it was time for a change. After talking with family and friends for a way to keep our little ones safe, we came up with the idea that could either be implemented into the harness or seating area of a car seat or passenger seat that, once outside of bluetooth range (approx 25-50ft), your phone will alert you with a haptic and loud audible tone that you have someone still in the vehicle. Only after going back and taking the child out of the car or acknowledging that the child is being left with a responsible person in the vehicle, would the alarm stop. I hope this safety system will seriously cut down or entirely stop children from being left in vehicles and facing possible harm!

2. The Problem: What problem are you helping to solve?

The issue with children being left or forgotten in vehicles which could cause harm.

3. Your Solution: How are you planning to solve this problem? Share your specific approach.

Reaching out to individual developers or car seat producers to implement a device into the harness or seat that will notify the parent once the device has exited bluetooth range with an alarm that will continue to notify the person until they either acknowledge that the child is being left with a responsible person or until the child is removed from the seat.

4. Example: Please walk us through a specific example of what happens when a person or group gets involved with your project.

They will be helping either develop the device or helping write the software that will be implemented with the device that will be connected to the car seat.

5. The X Factor: What is different about your project compared to other programs or solutions already out there?

Most of the attempts available, from what has been notably used is just signage or reminders set my individual merchants or businesses reminding customers to check for children left behind.

6. Impact: How has your project made a difference so far?

While this is merely in its 'idea' phase. I strongly believe that this could revolutionize child safety worldwide and even be implemented in other means or built directly into new production vehicles as a standard safety feature.

7. What’s Next: What are your ideas for taking your project to the next level?

Reaching out to major safety system manufacturers for help with development of this project or building a team to make this project our own reality.

8. Future Support: What are the resources needed to make your vision a reality?

I would be looking for team members with technical and electrical knowledge to help build prototypes for this project, sponsorship to help the public see this revolutionary safety system and funding to help this product hit the main stream market and truly make our world a safer place!

10. Ripple Effect: Please share some ideas of how you could partner with other changemakers or involve other young people as leaders in making a difference.

Anyone who has the technical knowledge of coding for mobile applications and anyone with the knowledge of building electronic devices are more than welcome to reach out to become a team member and make this product real!

I believe this is a good concept. It’s horrible to hear how so many incidents of children being left behind in cars. Your concept of designing a device that can be implemented into the harness or seating area of a car, then once outside of bluetooth range the phone will alert with a loud audible tone that someone still in the vehicle. Great idea!

This could definitely be extended to every child that has been left unattended in different situations. thank you for sharing. Depending on the age group, it could even be a toy that the kid has and it connects with your phone.

This is such a great idea! I see two paths your idea could go in:
1) You create a connected device that can be installed in any car seat
2) Or you bring this idea to car seat manufacturers and try to convince them to include something like this in their car seats.

The latter would likely create more change, but would be much more difficult than the former. I would suggest starting with the former to create a prototype, and then approach car seat manufacturers to see if they would include your device in their car seats.
