Concept Development

Concept Generation

The concept generation shows different concepts we identified for the selection of the foam.

Test Rig Concept Generation

The test rig concept selection shows different ideas and approaches towards building a test rig.

Different designs created for the test rig are considered here: Test Rig Designs

Concept Selection

We have not fully selected one concept and will not choose one until drop testing and prototyping as well as CAD simulation models have been created. You will find the Pugh Analysis with different selection criteria which helped us narrow down a few concepts to test and use.

Systems Architecture

Our proposed system design can be found here: Systems Architecture

This is an overview of what the process will look like and what functions the foam and the drop test rig must perform.

Feasibility Analysis

We have narrowed down four important feasibility analyses to perform.

1. What will the helmet need to withstand for G-forces upon impact in order to protect players from concussions?

Impact Forces Analysis

2. How many impacts will the padding have to be reliable/durable for? How many seasons must it be able to last before needing to be replaced?

Durability Analysis

3. Can we design a test rig that matches the specifications of standard testing equipment that is repeatable, and will allow us to test different impact scenarios?

Test Rig Design Analysis

4. Approximately how much will a prototype cost?

Prototype Cost Analysis

Risk Assessment

Risk Assessment

We came up with 23 different risks that could occur during the project and plans of action in case any of these risks actually happen.

-Project Plan:

All of the notes from the review have been addressed and updated.

Things that we need to experiment with:

1. Importing the 3D scan into solid works

2. Positioning the head scan in to the helmet in solid works. -It was suggested that reference points could be used to help with this. We will have to develop an easy way to do this because it will eventually become part of our work flow.

3. Creating CAD models of the different geometries we want to test and perform virtual testing to save time and materials.

4. Deciding what to use as the test dummy head inside the helmet.
