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. :)

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.

Russian Doll Maze Variant
Hello Designers! I am looking for a variant of the "Russian Doll Maze Puzzle" on Thingiverse. Here's a little bit about the project: I run a small home business in Utah that provides 3D printing services for the local area. Lately, we've been donating our extra machine time to making these puzzles for charity (Anti-boredom bags for children in hospital waiting rooms.) They've been a massive hit among the kids, however we've been hearing that the locking mechanism is 'unsnapping' over time while the puzzle is assembled, making them inoperable. We'd like to remedy that for the future! A few required design change specifications: 1. Cylindrical instead of Octagonal 2. The maze "Locking" mechanism needs a fix. Currently, it snaps "Up" into position, however the clicking mechanism is small and wears down, resulting in older puzzles 'locking' inside because they've come undone. We're looking for innovative solutions to solve this issue (potentially rotating sideways at the end, instead of up, to add another safety mechanic) 3. Thick bottom and outer wall for embossing names, if chosen. Needs to be strong enough for children to not break with regular usage. 4. Difficulty of maze appropriate to 8 and up age levels. Dimensions overall approximately 4" height, 2 1/2" round. 1/8" to 5/16" inner wall construction (solid).
Pool Zones
Need 3D structure studios pool design in zero edge pool and spa: MUST BE Zero Edge Pool and spa: shown in photographs Create some large stepping stones and create the slope shown from one side to other of 15". Basic and minor details for the house (keep house basic outline in 3D or show house as pad only) Some grade changes in the yard as well: yard drops from one side of the to the other by up to 15" Use the pool in the updated plan for the dimensions and pool and spa sizing.
