Element i: Prototype Testing and Data Collecting with Results

Problem Statement

According to the U.S. Department of interior, approximately 90% of all wildfires are caused by human interference leading to approximately 6.9 million acres of burnt fields and homes. This problem has led to millions of people without homes and has led to major economic problems, due to the fact that most cities cannot function without proper human infrastructure. If this problem continues, wildfires can lead to long term effects that can be irreversible and many people living near forests have the potential of losing their home.

Introduction

Testing is conducted to ensure the successful performance of any engineering design solution. During testing, I will examine and evaluate my solution to determine its ability to meet the predetermined specifications. I will also be documenting the effectiveness and reliability of the materials to ensure I get precise results.

Conclusion

In this phase of the design process I learned the importance of collecting all required materials including cost, quantity, and place of purchase. In addition, I learned the value of developing detailed testing procedures to collect data that can be analyzed to understand how my prototype meets my design specifications. During one of my tests, one of the jet sprays from the third artificial tree broke due to high pressure. As a result I had to replace the broken jet spray and double check that all four artificial trees were in good condition before continuing the test. Overall, performing all of these test were truly satisfying since my brainstorming, research and design truly measured my standards.
