:: To Review:

The goal of Pillar’s is to have an integrated system that will identify, detect, alarm, locate, and respond to a drowning event. Several criteria and constraints were developed, and used to analyze the design alternatives and choose a final design.

::  Design Criteria:

The design must be:

• Safe and Reliable

• Robust

• Sustainable

• An attractive solution

• Cost Effective

::  Design Constraints:

The design must:

•     Successfully detect an event in less than 10 seconds

•     Successfully initiate and complete an automated response in less than 40 Seconds

•     Be water resistant – The mechanism will be exposed to water and therefore the detection and response mechanism should be water resistant. 

•     Have an operational life span of 30 years – A back-yard pool has a life span of approximately 30 years, according to a private pool installation company, therefore requiring the mechanism to have the same maximum lifespan.  

•     Have a manual emergency backup system – In case of a failure in the system, the response mechanism can be initiated through a manual emergency backup system.

•     Have a bystander e-stop – If the mechanism is malfunctioning, it can be stopped by a bystander using an e-stop button.
