Cuto!

Creating a cutting knife for children that is safe, intuitive, and easily used.

Description

This project was created during my sophomore SolidWorks class at RISD. We were given a task to redesign an object for a specific group of users for the final redesign projects. I have selected children as my target users, and the object I have selected is a cutting knife. My goal is to design a safe, ease-to-use tool for kids.

BACKGROUND

Inspiration from Observation

While working at the children's art program a year ago, I realized that we still lacked a tool that could help children with crafts.

01/
A lack of efficiency.

While working at the children's art program a year ago, I realized that we still lacked a tool that could help children with crafts. Many of the children were using plastic scissors, which were not only inefficient but also not user-friendly.

02/
Hard to use.

On the other hand, when using a utility knife, they had trouble cutting clean lines due to their lack of strength. Additionally, some of the utility knives were too big for small children's hands.

Target User: Children of age 4-10

With the observation in mind, I have decided to make the target users children from 4 - 12 years old, during an age that need many creative crafting yet still unable to control their bodies fully.

DEFINE PROBLEMS

Dissemble

To understand the mechanism of the product, I first disassembled it to have a greater look at the connections and relationships between each individual part. By doing so, I can gain a deeper knowledge of the functionality, which can inform my later design.

The problems

The current utility knife has great cutting functionality. However, it is not user friendly to the children. Here are some problems that younger children will face while using regular utility knife in their daily life:

01/
Potential injuries.

It is very easy for the children to get injured due to the long and sharp knife blade.

02/
Lack of Strength.

When students use utility knife, they tend to have unequal cuts due to lack of strength.

03/
Unmatched Size.

Children's hands are way smaller than those of adults, making their hands unsuited for the ergonomics

SOLUTION

Redesign the utility knife to improve safety, functionality and comfortability for the children.
