Translucent Head Impact Model for Brain Trauma Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing the effects of head impacts on the brain lack a simulated model that includes a brain component, making it difficult to measure direct brain trauma and evaluate the effectiveness of protective gear in reducing brain acceleration and trauma.
Innovation Solution
A head impact test system comprising a head model with a skull, brain, and fluid components, coupled with a mount and a translucent cover, which allows for imaging of the brain during impact, enabling analysis of motion factors such as velocity and deformation using a camera and computer analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a head impact test system includes a brain component and translucent cover for imaging, then measurement precision of brain trauma is improved, but device complexity increases
Solution Approach 1:
The patent creates a simplified model copy of the human head including skull, brain, and fluid components rather than testing on actual human subjects. This model copy enables precise measurement of brain trauma through imaging while avoiding the complexities and ethical issues of human testing.
Solution Approach 2:
The translucent cover acts as an intermediary that allows optical imaging systems to observe brain component movement and deformation during impact without interfering with the impact mechanics. This mediator enables measurement precision while maintaining a relatively simple test setup.
2Reliability
If the head model includes fluid component surrounding the brain, then reliability of brain trauma simulation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent uses a fluid component (hydraulic analog) to surround the brain component within the skull, simulating the cerebrospinal fluid environment. This hydraulic approach reliably reproduces the mechanical behavior of real brain tissue during impact while allowing for manufacturing tolerances in the head model assembly.

AI summary
An impact test system includes a head model having a head exterior component; a skull component; a brain component; a fluid component; an interior cavity surface; and a translucent cover, wherein the head model is coupled with a mount, the brain component and fluid components are configured within the interior cavity, and wherein the translucent cover is configured over a portion of the brain component and fluid component. A mount is configured to a least partially restrain the head model. A camera is configured to take a plurality of images of the brain and the fluid components through the translucent cover when the head model is under an impact force.
