Description:
Hello,

I work in a research lab at the University of Utah. We need to make a frame that can hold a patient's head in place while we image their brain with custom ultrasound transducers.

We have designed the transducers and general shape of the brain helmet. We are seeking solutions to 1) mechanically holding the head in place and 2) making the frame as aesthetically pleasing as possible. All mechanisms for adjustment (i.e. extention/retraction) should be complete in the design i.e. functional.

I attached the solidworks files and a very quick (and ugly) sketch of the general concept. This is just the first idea so please take this as a jumping-off point and feel free to be creative!

Our one requirement is that one of the head fixation parts be a sliding piece over the middle of the head that fixes to the bride of the patient's nose (called the nasion).
Wants:
Completeness of adjustment mechanism details and practicality.
Solution for adjustable fixation of the bride of the nose.
As aesthetically pleasing as possible. Sleek, beautiful form.
Don't Wants:
Ugly bulky design
Impractical design with no possibility of 3d printing
Vague or non-functional mechanisms.
Software:
  1. SolidWorks

I can work on some light weighting approaches if that is what the main goal is, keeping in mind 3d printing and respective additive manufacturing constraints.

@Chaniago No logo for this project, thanks. We are going for a sleek, high-quality, professional look. The ultrasound arrays do not need to be adjustable, in fact they need to be fixed. The head fixation mechanisms are the only thing that should be adjustable. The existing ultrasound array cannot be modified. However, do not worry too much about creating a way to embed them into the device. We will figure that out when we design this for manufacturing. We need you to focus on the form of the frame that surrounds the arrays and head fixation mechanisms only.

Hi...Tom
I have a few things I want to ask
*Do you need a logo on this product. If needed, please share the log ?
*Do ultrasound arrays have to be adjustable ?
*Is it possible if I modify the existing ultrasound array ?

Regards,
Chaniago

@Ysuf Aryasa Thanks for checking. No electrical components in the frame. It is just for holding the patient's head and transducers.

Hello Tom, are there any electrical components in the frame? Or just only for holding the transducers and the patient's head?

Thank you.

@Steven wijay Just design for 3D print is sufficient. Thanks!

@Harry the transducer case DopplerPhasedArray1 cannot be changed unfortunately. Everything else around it can though. Hoping to make the frame sleek to hide this bulky transducer.

Hai Tom, i have one question. your goal for now is only good design and 3d printable ? or wanna until mass production ? because there is different design method for them both.

if you wanna design for 3dprint. i can do optimal for that goal.

Thanks for the .step file.
Now my question is can we change the shape and size of the bulky transducer case? If we can, what's the minimum size?

@Harry S. I uploaded a .STEP file of the array assembly. The ultrasound transducers are the parts labeled 'DopplerPhasedArray1'. Let me know if you have any questions.

I can't open the files in SW 2019. Could you save to older version or to .step files?

Solidworks is preferred. But if Blender can export to STL for 3d printing then that is fine.

May I make it in Blender software?

I may not understand your question, sorry, but I will try to give as much information as I can. The human will be lying down with their head fixed in place within the device. There needs to be no material between the arrays and patient's head so ultrasound can pass through uninterrupted. I.e. nothing can be on the sides of the head between the transducers. Gel pads that press agaist the forehead could work! As long as they are adjustable to fit several different adult patients - male and female (this typically requires 40 mm of adjustable length).

If not need to be human head in fixed places. Why not using gel pad and strap it on to bicycle helmet. :)
Wed, 06 Oct 2021 11:25:55 +0000
Hmm, does the human head need to be in fixed place so the scanner could scan easliy? or redesign the helmet to scan a brain?

It was an M3 screw. But any screw is accessible to us.

Can you tell me which screw where used with the 3 D print i.e which is easily accessible to you.

"They Might Be Giants" School Award
I am a local community member working with a K-8 school principal to develop a custom award for two members of their faculty to be given out each year. The award is called "They Might Be Giants" and it celebrates educators who have been the "shoulders" that younger educators have stood on. Think like a mentor, but more than that. Ultimately the creation from this contest will be 3D Printed and integrated into the final award. Think 6" - 8" high 3D giant. I'm open to ideas, but the attached pictures provides a good references of the giant idea and it supporting people on its shoulders. If you notice the male and female standing on the giant's shoulders in the reference photo you get a sense of them looking into the horizon. Where the Giant has a sense of forward motion. It is the combination of the sense of movement toward the horizon, and the eagerness to look toward the future that I to capture with this 3D element. The working concept for this award is based on an award presented by the Advertising Hall of Fame called "The Golden Ladder" Award (See attached photo). In place of the golden ladder will be the giant element that this contest is looking to produce. The total height from the foot of the giant, to the top of the tallest head of the person standing on the giant's shoulders will be no more than 8" high
