Collapsible Kicksled

Goal

The goal of this third year project was to create a kicksled that uses traditional materials, is fun with friends and collapses for easy storage.

Materials

The use of wood and sinew in the design of kicksleds is nothing new. However, using traditional materials and minimalist design to create a collapsible sled is.

Functionality

I primarily focused on the mechanism that would allow the kicksled to collapse. During this phase of the design I planned out how I would bend the skis and what the dimensions for each piece would be.

 
Ergonomic User Testing

Static Model

First, a full-scale static model was created to ensure the ergonomics of the kicksled were correct.

Functional Prototype

Next, a full-scale model was created to perform real-world user testing. A lot was learned and a lot of fun was had along the way.

 

User Testing

Once the functional prototype was created, it was tested on snow with a several users.

Appearance Model

With user testing completed, I started to figure out how I was going to build the final appearance model. I decided to use basswood as it is easy to work with and very light.

Appearance Model

Once I had cut and sanded the main structure of the sled, the slots that allow it to collapse needed to be made using the milling machine.

Appearance Model

To create the skis for the sled I steam bent plywood and molded it around a jig to the desired shape. Using two sheets of plywood per ski created tension and compression forces acting in opposite directions, making it very strong.

 
Sanding final appearance model

Appearance Model

Once all of the structural elements and skis were made it was time to fasten them together and sand the entire model. The appearance model was created over the course of four (very long) days.

 
 

Renderings

Renderings were created for presentation material and to show the sled in different orientations.
