Since this is for children, making it smaller with probably less weight constraints, I wonder if it could be bass inject plastic like some plastic furniture (Bellini chair).

I second the prototypes thing. Make a bunch of simple dirty models out of pink foam and photo with kids, rough plywood cut outs, whatever.

Hi Yo,

Imagining children will be using this 24/7, light weight is an important aspect to remember. Some materials we proposed are aluminum since its very cheap, polycarbonate which surprisingly light and strong, and also carbon fiber but keeping in mind the expensive price. Do you have any more suggestions on materials that I possibly could use?

As a group (it is a group project), we did some quick mockups out of pvc tubing. As long we can explore and get feed back on the structure and how it feels when its being used.

Thank you :)

It looks to me like you are styling something. Have you spent time with disabled children that use walkers, have you looked into grip strength, balance, weight of the devices, how will it collapse for transport, how will it work indoors and out and on various surfaces. And, for the age range your designing for, adjustability to accommodate for changing height, arm length, grip size and user weight over time,

Hi Dan Lewis,

One of the main focus on this assignment is about styling, exploring style and forms. I have to tell you that the sketches were in the very beginning stage of the process. As I work on more, I do have some adjustment on the configurations.

The population of the user will be children that able to walk and have upper body strength ( mild diplegia). So they will be able to stand, walk, and have strength to grip the handles. The purpose of the walker for them is for their balance. Adding to some thought about the grip on handle, it might be on angle instead of straight because the children tented to "rest" their arm on the handle bar and having the grip on handle on angle will be more comfortable for them.

How it will collapse, it will have hinges on the leg so it folds up, the other two legs will fold up like an umbrella, the handle will fold down. Roughly that is the idea for now. The form after its collapse will be only as big as a backpack.

All the parts are adjustable to provide the user's growth since it will be use for years as they grow up.

Thanks
While my question may not seem relevant to the design process, it does have an impact that, in my perception, is rarely addressed by students. This by no means is the fault of the student. I squarely put the blame on your instruction.

I would like to preface the following rant with I truly believe there is value in design exercises that are not constrained to reality. My problem when I review portfolios from new graduates, it seem there is little, if any, regard to those constraints. And it is frustrating because I have to train the fresh graduate with those limits when they should have gotten some instruction about it.

So back to the insurance/Medicaid question. They are the entities that will pay for your walker. Sure, you will have a very low percentage of people paying directly. But there is no company in the world that will base their total available market on people paying cash for a medical device. Not gonna happen. Insurance companies and Medicaid have rules about medical device reimbursement. A company producing your walker will follow those rules.

You are certainly don't have to follow this constraint for this project. But please pressure your instructors to at least inform you of these limitations when you are designing. Your future employer will appreciate that you have that knowledge.

I'm open to any question about this project not just from the design point of view :)

Yeah, as a class our in structure never mentioned anything about how the insurance or Medicaid will reimburse it. Thank you so much for explaining it to me.
I would have no idea about it if you never mention it. I honestly thought that the insurance or Medicaid will just reimburse it. but again, thank you so much for the information. I will let my instructor know about this.

Thank you :)

Nice sketches. I had two projects like this when I was in school too for "design walking devices". One of them was called the "Quick Step by Arbin Care" the other was called "Rollz Motion". They both had pretty cool designs, just google the names they might give you some inspiration.

Hi Svenas,

I googled both of your project. Looking really good. The idea of the Rollz Motion is really nice. Able to flip it from wheel chair into walker are brilliant.
Doing the research for this project a lot of the users do need BOTH walker and wheelchair. The design of the Quick Step is really nice too. Simple and approachable.

A little update before the final next week.

Here is my final design. Still do some refinement for the graphic details, but this is so far I have and might be my final direction.

the reason behind the color choice are orange is a safety color and also general colors for booth girls and boys,

any color suggestions for children ages 8 - 12? other than orange.

I don't quite understand how it is used. Can you put the silhouette of a person in there to show use?

Hey there. I see you're from AAU? I might go to that school
in the future if funds permit...

Anyway A few friendly suggestions....

Seems like you need some REALLY good inspirational items to look into
researching before even putting that pen & maker to paper....

Since its a walker and has "legs" I highly suggest thinking out of the box
for this project and look into robot legs.
Here's a quick google search I did for you:

https://www.google.com/search?site=imgh ... s&tbm=isch


Robots are great inspirational sources to draw from!
Even some vehicle design can be traced from japanese
gundam and robotech robots.

Another good source of inspiration are those caterpillar and komatsu
construction equipment... Like for instance the forklifts can signify
(from an emotional design perspective) STRENGTH AND SUPPORT.
This is a good concept to draw on your project since you want your walker
to have STRENGTH AND SUPPORT for the kid using it... :D

Here's a good source:

https://www.google.com/search?site=imgh ... t&tbm=isch


There are MANY other sources of inspiration you can draw from as well.
You just have to look for them....
Lastly, you can try listening to "Save tonight" by Eagle Eye Cherry
and a cup of coffee and start cranking those sketches and see what you find... Good luck! :mrgreen:
